2021-02-15:
- rebased on v5.11 final
- fixed anx7688 fw flashing timeout
- added Samuel's patches:
  - allow to use RTC wakeup when powered off
  - NVMEM driver for RTC data registers
- pulled in some fixes from linux-next into fixes-5.11
- 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)

  - 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

  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

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

This is the 5.10.16 stable release

This is the 5.4.98 stable release

This is the 4.19.176 stable release

wireless-drivers-next patches for v5.12

Second set of patches for v5.12. Last time there was a smaller pull
request so unsurprisingly this time we have a big one. mt76 has new
hardware support and lots of new features, iwlwifi getting new
features and rtw88 got NAPI support. And the usual cleanups and fixes
all over.

Major changes:

- Blank screen fix

Power management fixes for 5.11-rc8

Address a performance regression related to scale-invariance on x86
that may prevent turbo CPU frequencies from being used in certain
workloads on systems using acpi-cpufreq as the CPU performance
scaling driver and schedutil as the scaling governor.

ACPI fix for 5.11-rc8

Revert a problematic ACPICA commit that changed the code to attempt
to update memory regions which may be read-only on some systems (Ard
Biesheuvel).

Release: orange-pi-5.10-20210210-1337

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

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!
