+Date: Wed, 30 Mar 2022 16:16:56 +0200
+Subject: [PATCH] mtd: spi-nor: support eon en25qh256a variant
+
+The EN25QH256A variant of the EN25QH256 doesn't initialize correctly from SFDP
+alone and only accesses memory below 8m (addr_width is 4 but read_opcode takes
+only 3 bytes).
+
+Set SNOR_F_4B_OPCODES if the flash chip variant was detected using hwcaps.
+
+The fix submitted upstream uses the PARSE_SFDP initializer that is not
+available in the kernel used with Openwrt.

+Subject: [PATCH] nvmem: core: Add support for keepout regions
+
+Introduce support into the nvmem core for arrays of register ranges
+that should not result in actual device access. For these regions a
+constant byte (repeated) is returned instead on read, and writes are
+quietly ignored and returned as successful.
+
+This is useful for instance if certain efuse regions are protected
+from access by Linux because they contain secret info to another part
+of the system (like an integrated modem).

+Subject: [PATCH] nvmem: Add driver to expose reserved memory as nvmem
+
+Firmware/co-processors might use reserved memory areas in order to pass
+data stemming from an nvmem device otherwise non accessible to Linux.
+For example an EEPROM memory only physically accessible to firmware, or
+data only accessible early at boot time.
+
+In order to expose this data to other drivers and user-space, the driver
+models the reserved memory area as an nvmem device.

+Subject: [PATCH] nvmem: core: Add functions to make number reading easy
+
+Sometimes the clients of nvmem just want to get a number out of
+nvmem. They don't want to think about exactly how many bytes the nvmem
+cell took up. They just want the number. Let's make it easy.
+
+In general this concept is useful because nvmem space is precious and
+usually the fewest bits are allocated that will hold a given value on
+a given system. However, even though small numbers might be fine on
+one system that doesn't mean that logically the number couldn't be
+bigger. Imagine nvmem containing a max frequency for a component. On
+one system perhaps that fits in 16 bits. On another system it might
+fit in 32 bits. The code reading this number doesn't care--it just
+wants the number.
+
+We'll provide two functions: nvmem_cell_read_variable_le_u32() and
+nvmem_cell_read_variable_le_u64().
+
+Comparing these to the existing functions like nvmem_cell_read_u32():
+* These new functions have no problems if the value was stored in
+  nvmem in fewer bytes. It's OK to use these function as long as the
+  value stored will fit in 32-bits (or 64-bits).
+* These functions avoid problems that the earlier APIs had with bit
+  offsets. For instance, you can't use nvmem_cell_read_u32() to read a
+  value has nbits=32 and bit_offset=4 because the nvmem cell must be
+  at least 5 bytes big to hold this value. The new API accounts for
+  this and works fine.
+* These functions make it very explicit that they assume that the
+  number was stored in little endian format. The old functions made
+  this assumption whenever bit_offset was non-zero (see
+  nvmem_shift_read_buffer_in_place()) but didn't whenever the
+  bit_offset was zero.
+
+NOTE: it's assumed that we don't need an 8-bit or 16-bit version of
+this function. The 32-bit version of the function can be used to read
+8-bit or 16-bit data.
+
+At the moment, I'm only adding the "unsigned" versions of these
+functions, but if it ends up being useful someone could add a "signed"
+version that did 2's complement sign extension.
+
+At the moment, I'm only adding the "little endian" versions of these
+functions. Adding the "big endian" version would require adding "big
+endian" support to nvmem_shift_read_buffer_in_place().

+
+The shifting of the u8 integer buf[3] by 24 bits to the left will
+be promoted to a 32 bit signed int and then sign-extended to a
+u64. In the event that the top bit of buf[3] is set then all
+then all the upper 32 bits of the u64 end up as also being set
+because of the sign-extension. Fix this by casting buf[i] to

+Subject: [PATCH] nvmem: core: allow specifying of_node
+
+Until now, the of_node of the parent device is used. Some devices
+provide more than just the nvmem provider. To avoid name space clashes,
+add a way to allow specifying the nvmem cells in subnodes. Consider the
+following example:
+
+    flash@0 {
+        compatible = "jedec,spi-nor";
+
+        partitions {
+            compatible = "fixed-partitions";
+            #address-cells = <1>;
+            #size-cells = <1>;
+
+            partition@0 {
+                reg = <0x000000 0x010000>;
+            };
+        };
+
+        otp {
+            compatible = "user-otp";
+            #address-cells = <1>;
+            #size-cells = <1>;
+
+            serial-number@0 {
+                reg = <0x0 0x8>;
+            };
+        };
+    };
+
+There the nvmem provider might be the MTD partition or the OTP region of
+the flash.
+
+Add a new config->of_node parameter, which if set, will be used instead
+of the parent's of_node.

+Subject: [PATCH] nvmem: core: fix error handling while validating keepout
+ regions
+
+Current error path on failure of validating keepout regions is calling
+put_device, eventhough the device is not even registered at that point.
+
+Fix this by adding proper error handling of freeing ida and nvmem.

+Subject: [PATCH] nvmem: nintendo-otp: Add new driver for the Wii and Wii U OTP
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This OTP is read-only and contains various keys used by the console to
+decrypt, encrypt or verify various pieces of storage.
+
+Its size depends on the console, it is 128 bytes on the Wii and
+1024 bytes on the Wii U (split into eight 128 bytes banks).
+
+It can be used directly by writing into one register and reading from
+the other one, without any additional synchronisation.
+
+This driver was written based on reversed documentation, see:
+https://wiiubrew.org/wiki/Hardware/OTP

+
+The Nintendo Wii and Wii U OTP is only present on Nintendo Wii and Wii U
+consoles.  Hence add a dependency on WII, to prevent asking the user
+about this driver when configuring a kernel without Nintendo Wii and Wii
+U console support.

+Subject: [PATCH] nvmem: core: rework nvmem cell instance creation
+
+In the existing design, we do not create a instance per nvmem cell consumer
+but we directly refer cell from nvmem cell list that are added to provider.
+
+However this design has some limitations when consumers want to assign name
+or connection id the nvmem cell instance, ex: via "nvmem-cell-names" or
+id in nvmem_cell_get(id).
+
+Having a name associated with nvmem cell consumer instance will help
+provider drivers in performing post processing of nvmem cell data if required
+before data is seen by the consumers. This is pretty normal with some vendors
+storing nvmem cells like mac-address in a vendor specific data layouts that
+are not directly usable by the consumer drivers.
+
+With this patch nvmem cell will be created dynamically during nvmem_cell_get
+and destroyed in nvmem_cell_put, allowing consumers to associate name with
+nvmem cell consumer instance.
+
+With this patch a new struct nvmem_cell_entry replaces struct nvmem_cell
+for storing nvmem cell information within the core.
+This patch does not change nvmem-consumer interface based on nvmem_cell.

+Subject: [PATCH] nvmem: core: add nvmem cell post processing callback
+
+Some NVMEM providers have certain nvmem cells encoded, which requires
+post processing before actually using it.
+
+For example mac-address is stored in either in ascii or delimited or reverse-order.
+
+Having a post-process callback hook to provider drivers would enable them to
+do this vendor specific post processing before nvmem consumers see it.

+Subject: [PATCH] nvmem: core: Fix a conflict between MTD and NVMEM on wp-gpios
+ property
+
+Wp-gpios property can be used on NVMEM nodes and the same property can
+be also used on MTD NAND nodes. In case of the wp-gpios property is
+defined at NAND level node, the GPIO management is done at NAND driver
+level. Write protect is disabled when the driver is probed or resumed
+and is enabled when the driver is released or suspended.
+
+When no partitions are defined in the NAND DT node, then the NAND DT node
+will be passed to NVMEM framework. If wp-gpios property is defined in
+this node, the GPIO resource is taken twice and the NAND controller
+driver fails to probe.
+
+It would be possible to set config->wp_gpio at MTD level before calling
+nvmem_register function but NVMEM framework will toggle this GPIO on
+each write when this GPIO should only be controlled at NAND level driver
+to ensure that the Write Protect has not been enabled.
+
+A way to fix this conflict is to add a new boolean flag in nvmem_config
+named ignore_wp. In case ignore_wp is set, the GPIO resource will
+be managed by the provider.
+

+
+nvmem_unregister() frees resources and standard pattern is to allow
+caller to not care if it's NULL or not. This will reduce burden on

+
+sc7180 blow fuses got slightly chances to hit qfprom_reg_write timeout.
+Current timeout is simply too low. Since blowing fuses is a
+very rare operation, so the risk associated with overestimating this
+number is low.
+Increase fuse blow timeout from 1ms to 10ms.

+Subject: [PATCH] nvmem: microchip-otpc: add support
+
+Add support for Microchip OTP controller available on SAMA7G5. The OTPC
+controls the access to a non-volatile memory. The memory behind OTPC is
+organized into packets, packets are composed by a fixed length header
+(4 bytes long) and a variable length payload (payload length is available
+in the header). When software request the data at an offset in memory
+the OTPC will return (via header + data registers) the whole packet that
+has a word at that offset. For the OTP memory layout like below:
+
+offset  OTP Memory layout
+
+         .           .
+         .    ...    .
+         .           .
+0x0E     +-----------+	<--- packet X
+         | header  X |
+0x12     +-----------+
+         | payload X |
+0x16     |           |
+         |           |
+0x1A     |           |
+         +-----------+
+         .           .
+         .    ...    .
+         .           .
+
+if user requests data at address 0x16 the data started at 0x0E will be
+returned by controller. User will be able to fetch the whole packet
+starting at 0x0E (or parts of the packet) via proper registers. The same
+packet will be returned if software request the data at offset 0x0E or
+0x12 or 0x1A.
+
+The OTP will be populated by Microchip with at least 2 packets first one
+being boot configuration packet and the 2nd one being temperature
+calibration packet. The packet order will be preserved b/w different chip
+revisions but the packet sizes may change.
+
+For the above reasons and to keep the same software able to work on all
+chip variants the read function of the driver is working with a packet
+id instead of an offset in OTP memory.

+Subject: [PATCH] nvmem: core: add error handling for dev_set_name
+
+The type of return value of dev_set_name is int, which may return
+wrong result, so we add error handling for it to reclaim memory
+of nvmem resource, and return early when an error occurs.

+Use kzalloc(...) rather than kcalloc(1, ...) because the number of
