KNOWN ISSUES:
- You must use crust-firmware/arm-trusted-firmware and the latest crust with this kernel
  branch on PinePhone, otherwise cpuidle will cause your phone to overheat and consume
  too much power (4W+). The proper TF-A/crust build is already available in my p-boot
  repository, so if you use p-boot just update the fw.bin.

  smaeul: "all idle entry attempts will return PSCI_E_INVALID_PARAMS, and Linux
  isn't smart enough to stop trying without these patches:
  https://github.com/crust-firmware/arm-trusted-firmware/commits/d6ebf5dab2daab8"

2021-06-05:
- rebase on linus/master (5.13-rc5)

  (until now it was hardcoded in device tree)
  - minimum brightness calibration instructions (default for lth_brightness is 10%,
    meaning is 'PWM duty cycle at the lowest brightness setting'):

  echo 1 > /sys/class/backlight/backlight/brightness
  echo 1 > /sys/class/backlight/backlight/device/lth_brightness
  echo 2 > /sys/class/backlight/backlight/device/lth_brightness
  echo 3 > /sys/class/backlight/backlight/device/lth_brightness

  ... increase values until you like the minimum brightness

  ... then make sure to restore this value after each boot by writing it to
  /sys/class/backlight/backlight/device/lth_brightness

2021-06-05:
- rebase on linus/master (5.13-rc4+)
2021-05-31:

2021-05-21:
- rebase on linus/master (5.13-rc2+)
2021-05-20:
- rebase on linus/master (5.13-rc2+)
- fixed up booting with fw_devlink=on (see fixes-5.13)
- applied Samuel's time travel avoidance fix https://patchwork.kernel.org/project/linux-arm-kernel/patch/20210515021439.55316-1-samuel@sholland.org/
  - this should fix occasional stalls and system hangs
- revert fine tuned OCV based capacity reporting, PMIC is not reporting OCV correctly
  so kernel has garbage input for the OCV -> capacity conversion and thus produces
  garbage output too (this stops large jumps in capacity when plugging in a charger
  and in general makes capacity reporting saner)
- fixed "NOHZ tick-stop error: Non-RCU local softirq work is pending, handler #08!!!"
- wifi driver no longer prevents dynticks from working
- improved (well..., added) suspend/resume code to anx7688 driver :)
  - fixes some issues caused by this driver ignoring the suspend/resume cycle

- rebase on linus/master (pre 5.13-rc1)
2021-05-01:
- fixed suspend failure of light/proximity sensor
- raise the default minimum frequency for mbus devfreq governor
  (you can still lower it in sysfs for higher runtime power savings at the cost
  of some performance, see /sys/class/devfreq and tune it there for your distro)
2021-04-26:
- rebase on 5.12 final
- fixed behavior with dumb charger (DCP) being forced to 500mA on boot from anx7688
  driver
- disable lradc wakeup by default (lowers the power consumption in suspend)
2021-04-25:
- rebase on linus/master
- I've created a patch that disables touchscreen controller during system sleep
  reducing power consumption by about 40mW in sleep (and by 130mW when touching
  the screen in sleep)
  - before: https://megous.com/dl/tmp/0533207eed42258c.png
  - after: https://megous.com/dl/tmp/5d504d680415e2e3.png
  - those power spikes are touch controller checking if there's a finger touching
    the screen, and those dense spikes are when the finger is actually touching
    the screen

- rebase on 5.12-rc4
2021-03-15:

- disable MMC runtime PM again (causes issues on H5/H6 https://megous.com/dl/tmp/1eec9b1c7f03ad93.png)
- used nvmem reboot driver (suggested by Samuel in RFC patch) for rebooting to FEL,
  eMMC bootloader, various p-boot boot configs on either eMMC or SD card's bootfs filesystems,
  boot menu, etc. via reboot() syscall with extra arg (see LINUX_REBOOT_CMD_RESTART2)
  (p-boot is also updated to support this mechanism, as of 2021-02-15)
2021-02-08:
- rebased on 5.11-rc7
2021-02-04:
- rebased on linus/master

2020-12-11:
- rebased on top of linus/master
2020-12-07:
- rebased on top of 5.10-rc7
2020-12-05:
- modem power driver: add more powerup modes and change interface for dumb and fastboot powerup
  - you can now write 2, 3 or 4 to .../powered sysfs file to select differnt powerup mode from
    the normal one (1)
  - this is useful for selecting alternate userspace configurations early in boot to allow
    tracing the userspace processes from early on for reverse engineering, and in the near
    future, it will be used to switch between original and fully-FOSS userspace code
    running on the modem's APPS CPU on powerup
    - see https://xnux.eu/log/#028
2020-12-02:
- fix WiFi blocking suspend
- improve modem power driver interaction with kernel's autosleep
- shorten resume times from 1.2s to 400ms (wifi driver optimization)
2020-11-30:
- I improved the anx7688 driver to actually respect PD capabilities of the source,
  and don't overload it. This should make it more likely to work with the USB-C
  docks when docks are powered.
- Pine64 dock can provide either 500mA when powered from regular USB-A charger
  (regardless of what kind of charger it is, it can't use more current from it)
- With my 3A PD charger, Pine64 dock will advertise 2600mA and Pinephone will
  now respect this limit.
- rebase on linus/master (5.10-rc6 atm)
- increase I2C clock for sensors and touchscreen/anx7688 from 100kHz to 400kHz
- added patch from https://patchwork.kernel.org/project/dri-devel/cover/20200222024210.18697-1-yuq825@gmail.com/#23237865
  for easier GPU debugging (suggested by bshah)

My kernel's main integration branch is 'orange-pi-$VER' (this one).
No other branch is supposed to work alone. My defconfigs are tested
and work on the boards I support. Read the README.md for more info.

Only my branches based on the current mainline kernel branch are
maintained (those are usually the -rc# kernels!). You can find the
current mainline version here https://www.kernel.org/ (mainline: ...)

My prebuilt kernels can be found at https://xff.cz/kernels/ You can
use them to test that your board works, or just run them without
bothering with building everything yourself. I run them on all my
boards.

My website is https://xnux.eu and may contain useful advice.

Good luck!
