From 675992be6f7b603b8cfda4678f173e1021fc1ab6 Mon Sep 17 00:00:00 2001
From: Vladimir Oltean <vladimir.oltean@nxp.com>
Date: Thu, 7 Oct 2021 19:47:10 +0300
Subject: [PATCH] net: dsa: mv88e6xxx: keep the pvid at 0 when VLAN-unaware
The VLAN support in mv88e6xxx has a loaded history. Commit 2ea7a679ca2a
("net: dsa: Don't add vlans when vlan filtering is disabled") noticed
some issues with VLAN and decided the best way to deal with them was to
make the DSA core ignore VLANs added by the bridge while VLAN awareness
is turned off. Those issues were never explained, just presented as
"at least one corner case".
That approach had problems of its own, presented by
commit 54a0ed0df496 ("net: dsa: provide an option for drivers to always
receive bridge VLANs") for the DSA core, followed by
commit 1fb74191988f ("net: dsa: mv88e6xxx: fix vlan setup") which
applied ds->configure_vlan_while_not_filtering = true for mv88e6xxx in
particular.
We still don't know what corner case Andrew saw when he wrote
commit 2ea7a679ca2a ("net: dsa: Don't add vlans when vlan filtering is
disabled"), but Tobias now reports that when we use TX forwarding
offload, pinging an external station from the bridge device is broken if
the front-facing DSA user port has flooding turned off. The full
description is in the link below, but for short, when a mv88e6xxx port
is under a VLAN-unaware bridge, it inherits that bridge's pvid.
So packets ingressing a user port will be classified to e.g. VID 1
(assuming that value for the bridge_default_pvid), whereas when
tag_dsa.c xmits towards a user port, it always sends packets using a VID
of 0 if that port is standalone or under a VLAN-unaware bridge - or at
least it did so prior to commit d82f8ab0d874 ("net: dsa: tag_dsa:
offload the bridge forwarding process").
In any case, when there is a conversation between the CPU and a station
connected to a user port, the station's MAC address is learned in VID 1
but the CPU tries to transmit through VID 0. The packets reach the
intended station, but via flooding and not by virtue of matching the
existing ATU entry.
DSA has established (and enforced in other drivers: sja1105, felix,
mt7530) that a VLAN-unaware port should use a private pvid, and not
inherit the one from the bridge. The bridge's pvid should only be
inherited when that bridge is VLAN-aware, so all state transitions need
to be handled. On the other hand, all bridge VLANs should sit in the VTU
starting with the moment when the bridge offloads them via switchdev,
they are just not used.
This solves the problem that Tobias sees because packets ingressing on
VLAN-unaware user ports now get classified to VID 0, which is also the
VID used by tag_dsa.c on xmit.
Fixes: d82f8ab0d874 ("net: dsa: tag_dsa: offload the bridge forwarding process")

From 28d0ed88f536dd639adf1b0c7c08e04be3c8f294 Mon Sep 17 00:00:00 2001
From: Thomas Pedersen <twp@codeaurora.org>
Date: Mon, 16 May 2016 17:58:50 -0700
Subject: [PATCH 01/69] dtbindings: qcom_adm: Fix channel specifiers
Original patch from Andy Gross.
This patch removes the crci information from the dma
channel property. At least one client device requires
using more than one CRCI value for a channel. This does
not match the current binding and the crci information
needs to be removed.
Instead, the client device will provide this information
via other means.

Subject: [PATCH 33/69] ARM: qcom: automatically select PCI_DOMAINS if PCI is
enabled
If multiple PCIe devices are present in the system, the kernel will
panic at boot time when trying to scan the PCI buses. This happens on
IPQ806x based platforms, which has 3 PCIe ports.
Enabling this option allows the kernel to assign the pci-domains
according to the device-tree content. This allows multiple PCIe
controllers to coexist in the system.

Subject: [PATCH 60/69] HACK: arch: arm: force ZRELADDR on arch-qcom
ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended
on most ARM architectures. This automatically calculate ZRELADDR by
masking PHYS_OFFSET with 0xf8000000.
However, on IPQ806x, the first ~20MB of RAM is reserved for the hardware
network accelerators, and the bootloader removes this section from the
layout passed from the ATAGS (when used).
For newer bootloader, when DT is used, this is not a problem, we just
reserve this memory in the device tree. But if the bootloader doesn't
have DT support, then ATAGS have to be used. In this case, the ARM
decompressor will position the kernel in this low mem, which will not be
in the RAM section mapped by the bootloader, which means the kernel will
freeze in the middle of the boot process trying to map the memory.
As a work around, this patch allows disabling AUTO_ZRELADDR when
ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders
which don't support device-tree, which is the case on certain early
IPQ806x based designs.

Subject: [PATCH 67/69] generic: Mangle bootloader's kernel arguments
The command-line arguments provided by the boot loader will be
appended to a new device tree property: bootloader-args.
If there is a property "append-rootblock" in DT under /chosen
and a root= option in bootloaders command line it will be parsed
and added to DT bootargs with the form: <append-rootblock>XX.
Only command line ATAG will be processed, the rest of the ATAGs
sent by bootloader will be ignored.
This is usefull in dual boot systems, to get the current root partition
without afecting the rest of the system.

Subject: [PATCH 1/4] ipq806x: gcc: add missing clk flag
Some flag are missing from the original code.
These clk can't be set using the protected-clock proprities as they
cause the malfunction of the serial interface.
These clks are needed for the rpm interface to work proprely or the
cpu regulators starts to fail as soon as they are disabled by the
kernel.

Subject: [PATCH 1/8] cpufreq: add Krait dedicated scaling driver
This new driver is based on generic cpufreq-dt driver.
Krait SoCs have 2-4 cpu and one shared L2 cache that can
operate at different frequency based on the maximum cpu clk
across all core.
L2 frequency and voltage are scaled on every frequency change
if needed. On Krait SoCs is present a bug that can cause
transition problem between frequency bin, to workaround this
on more than one transition, the L2 frequency is first set to the
base rate and then to the target rate.
The L2 frequency use the OPP framework and use the opp-level
bindings to link the l2 freq to different cpu freq. This is needed
as the Krait l2 clk are note mapped 1:1 to the core clks and some
of the l2 clk is set based on a range of the cpu clks. If the driver
find a broken config (for example no opp-level set) the l2 scaling is
skipped.

+title: CPU Frequency scaling driver for Krait SoCs
+
+maintainers:
+ - Ansuel Smith <ansuelsmth@gmail.com>
+
+description: |
+ The krait cpufreq driver is a dedicated frequency scaling driver
+ based on cpufreq-dt generic driver that scale L2 cache and the
+ cores. TEST
+
+ The L2 cache is scaled based on the max clk across all cores and
+ the clock is decided based on the opp-level set in the device tree.
+
+ Different core freq can be linked to a specific l2 freq and the driver
+ on frequency change will scale the core and the l2 clk based of the
+ linked freq.
+
+ On Krait SoC is present a bug and on every L2 clk change the driver
+ needs to set the clk to the idle freq before changing it to the new value.
+
+ This requires the qcom cpufreq nvmem driver to parse the different opp
+ core clk and an additional opp table for the l2 scaling.
+
+ If the driver detect broken config (for example missing opp-level) the
+ cpufreq driver skips the l2 scaling
+
+ Referring to this example opp-level can be used to link a range of cpu freq
+ to a specific l2 freq:
+ cpu opp freq 384000000 has opp-level 0
+ l2 opp freq 384000000 has opp-level 0
+ The driver will scale l2 to 384000000
+
+ cpu opp freq 600000000-1000000000 has opp-level 1
+ l2 opp freq 1000000000 has opp-level 1
+ The driver will scale l2 to 1000000000

Subject: [PATCH 1/2] mtd: nand: raw: qcom_nandc: add boot_layout_mode support
ipq806x nand have a special ecc configuration for the boot pages. The
use of the non-boot pages configuration on boot pages cause I/O error
and can cause broken data written to the nand. Add support for this
special configuration if the page to be read/write is in the size of the
boot pages set by the dts.

Subject: [PATCH] ARM: dts: qcom: reduce pci IO size to 64K
The current value is probably a typo and is actually uncommon to find
1MB IO space even on a x86 arch. Also with recent changes to the pci
driver, pci1 and pci2 now fails to function as any connected device
fails any reg read/write. Reduce this to 64K as it should be more than
enough and 3 * 64K of total IO space doesn't exceed the IO_SPACE_LIMIT
hardcoded for the ARM arch.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Sparse complains about mt7621_pci_ops symbol is not declared and asks if
it should be declared as static instead. Sparse is right. Hence declare
symbol as static.

Subject: [PATCH] PCI: mt7621: Move MIPS setup to pcibios_root_bridge_prepare()
On the MIPS ralink mt7621 platform, we need to set up I/O coherency units
based on the host bridge apertures.
To remove this arch dependency from the driver itself, move the coherency
setup from the driver to pcibios_root_bridge_prepare().

Subject: [PATCH] PCI: mt7621: Drop of_match_ptr() to avoid unused variable
We have stubs for most OF interfaces even when CONFIG_OF is not set, so we
allow building of pcie-mt7621.c in that case for compile testing.
When CONFIG_OF is not set, "of_match_ptr(mt7621_pcie_ids)" compiles to
NULL, which leaves mt7621_pcie_ids unused:
$ make W=1
drivers/pci/controller/pcie-mt7621.c:549:34: warning: unused variable 'mt7621_pcie_ids' [-Wunused-const-variable]
Drop of_match_ptr() to avoid the unused variable warning.

Subject: [PATCH] PCI: mt7621: Remove unused function pcie_rmw()
Function pcie_rmw() is not being used at all and can be deleted. Hence get
rid of it, which fixes this warning:
drivers/pci/controller/pcie-mt7621.c:112:20: warning: unused function 'pcie_rmw' [-Wunused-function]
Fixes: 2bdd5238e756 ("PCI: mt7621: Add MediaTek MT7621 PCIe host controller driver")

Subject: [PATCH] PCI: Let pcibios_root_bridge_prepare() access bridge->windows
When pci_register_host_bridge() is called, bridge->windows are already
available. However these windows are being moved temporarily from there.
To let pcibios_root_bridge_prepare() have access to these windows, move the
windows movement after calling this function. This is useful for the MIPS
ralink mt7621 platform so it can set up I/O coherence units and avoid
custom MIPS code in the mt7621 PCIe controller driver.

Subject: [PATCH] MIPS: add bootargs-override property
Add support for the bootargs-override property to the chosen node
similar to the one used on ipq806x or mpc85xx.
This is necessary, as the U-Boot used on some boards, notably the
Ubiquiti UniFi 6 Lite, overwrite the bootargs property of the chosen
node leading to a kernel panic when loading OpenWrt.

Subject: [PATCH] MIPS: add support for buggy MT7621S core detection
Most MT7621 SoCs have 2 cores, which is detected and supported properly
by CPS.
Unfortunately, MT7621 SoC has a less common S variant with only one core.
On MT7621S, GCR_CONFIG still reports 2 cores, which leads to hangs when
starting SMP. CPULAUNCH registers can be used in that case to detect the
absence of the second core and override the GCR_CONFIG PCORES field.
Rework a long-standing OpenWrt patch to override the value of
mips_cps_numcores on single-core MT7621 systems.
Tested on a dual-core MT7621 device (Ubiquiti ER-X) and a single-core
MT7621 device (Netgear R6220).

Add MTD support for the BoHong bh25q128as SPI NOR chip.
The chip has 16MB of total capacity, divided into a total of 256
sectors, each 64KB sized. The chip also supports 4KB sectors.
Additionally, it supports dual and quad read modes.
Functionality was verified on an Tenbay WR1800K / MTK MT7621 board.

Subject: [PATCH 1/2] mtd: rawnand: add driver support for MT7621 nand
flash controller
This patch adds NAND flash controller driver for MediaTek MT7621 SoC.
The NAND flash controller is similar with controllers described in
mtk_nand.c, except that the controller from MT7621 doesn't support DMA
transmission, and some registers' offset and fields are different.

+Ralink SoC GPIO controller bindings
+
+Required properties:
+- compatible:
+ - "ralink,rt2880-gpio" for Ralink controllers
+- #gpio-cells : Should be two.
+ - first cell is the pin number
+ - second cell is used to specify optional parameters (unused)
+- gpio-controller : Marks the device node as a GPIO controller
+- reg : Physical base address and length of the controller's registers
+- interrupt-parent: phandle to the INTC device node
+- interrupts : Specify the INTC interrupt number
+- ngpios : Specify the number of GPIOs
+- ralink,register-map : The register layout depends on the GPIO bank and actual
+ SoC type. Register offsets need to be in this order.
+ [ INT, EDGE, RENA, FENA, DATA, DIR, POL, SET, RESET, TOGGLE ]
+
+Optional properties:
+- ralink,gpio-base : Specify the GPIO chips base number
+
+Example:
+
+ gpio0: gpio@600 {
+ compatible = "ralink,rt5350-gpio", "ralink,rt2880-gpio";
+
+ #gpio-cells = <2>;
+ gpio-controller;

+ interrupt-parent = <&intc>;
+ interrupts = <6>;

Subject: [PATCH v5 1/2] pinctrl: Add driver for Awinic AW9523/B I2C GPIO
Expander
Date: Mon, 25 Jan 2021 19:22:18 +0100
The Awinic AW9523(B) is a multi-function I2C gpio expander in a
TQFN-24L package, featuring PWM (max 37mA per pin, or total max
power 3.2Watts) for LED driving capability.
It has two ports with 8 pins per port (for a total of 16 pins),
configurable as either PWM with 1/256 stepping or GPIO input/output,
1.8V logic input; each GPIO can be configured as input or output
independently from each other.
This IC also has an internal interrupt controller, which is capable
of generating an interrupt for each GPIO, depending on the
configuration, and will raise an interrupt on the INTN pin to
advertise this to an external interrupt controller.

+I2C for Ralink platforms
+
+Required properties :
+- compatible : Must be "link,rt3052-i2c"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- #address-cells = <1>;
+- #size-cells = <0>;
+
+Optional properties:
+- Child nodes conforming to i2c bus binding
+
+Example :
+
