Shane Synan 5163ca420f ipq806x: fix min<>target opp-microvolt DTS mixup
Rearrange all voltage triplets for "opp_table0" to match the
specifications.  "opp-microvolt" and "opp-microvolt-<name>" triplets
are in order of <target min max>, and NOT <min target max>.

Previously, the CPU would *always* spend its time at the "minimum"
voltage, ignoring the actual intended target.  This is a regression
from previous behavior.

On an NBG6817 with a Qualcomm CPU of PVS bin #2...
(see &opp_table0 -> opp-1725000000 -> opp-microvolt-speed0-pvs2-v0)

* Before:
/usr/bin/tail -n +1 /sys/kernel/debug/opp/cpu0/opp\:1725000000/supply-0/u_volt_*
==> /sys/kernel/debug/opp/cpu0/opp:1725000000/supply-0/u_volt_max <==
1260000

==> /sys/kernel/debug/opp/cpu0/opp:1725000000/supply-0/u_volt_min <==
1200000

==> /sys/kernel/debug/opp/cpu0/opp:1725000000/supply-0/u_volt_target <==
1140000

* After:
/usr/bin/tail -n +1 /sys/kernel/debug/opp/cpu0/opp\:1725000000/supply-0/u_volt_*
==> /sys/kernel/debug/opp/cpu0/opp:1725000000/supply-0/u_volt_max <==
1260000

==> /sys/kernel/debug/opp/cpu0/opp:1725000000/supply-0/u_volt_min <==
1140000

==> /sys/kernel/debug/opp/cpu0/opp:1725000000/supply-0/u_volt_target <==
1200000

To check voltages and frequencies at run time, use...
/bin/cat /sys/kernel/debug/regulator/regulator_summary &&
  /bin/cat /sys/kernel/debug/clk/clk_summary | grep "hfpll"

PROJECT IMMORTALWRT

The Core Source Code of ImmortalWrt

Welcome to our Telegram Group: @ctcgfw_openwrt_discuss.


How to make it

Minimum requirements

Linux with case sensitive
2G DDR2 RAM
2 CPU Cores (AMD64, 1.4Ghz)
25G disk space left
Has access to both ChinaNet & Internet

Install the necessary packages (for Ubuntu user)

sudo apt-get update -y
sudo apt-get full-upgrade -y
sudo apt-get install -y build-essential cmake asciidoc binutils bzip2 gawk gettext git libncurses5-dev libz-dev patch unzip zlib1g-dev lib32gcc1 libc6-dev-i386 subversion flex uglifyjs git-core gcc-multilib g++-multilib p7zip p7zip-full msmtp libssl-dev texinfo libreadline-dev libglib2.0-dev xmlto qemu-utils upx libelf-dev autoconf automake libtool autopoint ccache curl wget vim nano python2.7 python3 python3-pip python3-ply haveged lrzsz device-tree-compiler scons antlr3 gperf intltool mkisofs rsync

For mainland China & Ubuntu(16.04+) user, you may run the following command to setup quickly:

sudo bash -c "bash <(curl -s https://build-scripts.project-openwrt.eu.org/init_build_environment.sh)"

Clone the source

git clone -b openwrt-18.06-k5.4 --single-branch https://github.com/immortalwrt/immortalwrt && cd immortalwrt
./scripts/feeds update -a && ./scripts/feeds install -a

Configure your firmware

make menuconfig

Make it

make -j$(nproc) V=s

Tips

You'd better not use root to make it, or you may be not able to use.
Default login address: 192.168.1.1, username is root and password is password.
