[PATCH v2 00/14] Expand available features on Qnap TS433

[Heiko Stuebner <heiko@sntech.de>]

Thanks to the nicely supported rk3568, the hardest part for adding things,
is to pull things from the vendor-kernel and translating them to mainline
standards.

This series allows the TS433 to use all 4 bays [0], wiggle some LEDs and
access devices connected to all 3 usb ports.

The device runs stable now and might be usable for actual usage.

There is still a todo-list though:
- the ethernet mac address for the realtek chip seems correct,
  but the gmac0 interface currently uses a wrong one
- i2cdetect reports devices on i2c-1 on addresses 54,55,56,57
  model_Q0B20_Q0B30_10_10.conf from the original rescue image labels them
    VPD_MB = I2C:0x54, VPD_BP = I2C:0x56
  the meaning currently being unknown. Some eeprom maybe?
- The regulator tree is slightly dubious. Everthing seems to follow rk3568
  reference designs, but especially the regulator labeled vcc3v3_sd
  seems to supply some PCIe functionality. So I guess the device's
  schematics will look quite different than the regulators added to the
  vendor devicetree.
- Quite a bit of functionality is provided by the MCU connected to uart0.
  According to the model.conf there should be fan-control, a number of
  additional LEDs (status,locate,usb?)


Thanks to Qnap engineers adding an easily accessible header for maskrom
mode on the board, replacing the bootloader is also quite a breeze. A
branch on top of today's u-boot master branch can be found on [1]. I'll
submit that code to u-boot once I can cherry-pick the dts patches.


changes in v2:
- add patches for tsadc, gpio-keys, cpu-supply, pmic, gpu and io-domains


[0] I only have two drives right now, but I tested both the internal
sata connector as well as the PCIe connected sata controller in different
combinations.
