Subject: [RFC 0/3] Make WLAN and Bluetooth basically work for CI20

RFC V1 2023-02-15 18:31:58:
With the applied patch

rtc: jz4740: Register clock provider for the CLK32K pin

by Paul Cercueil <paul@...pouillou.net> it is now possible to make the
CI20 WiFi and Bluetooth setup do something reasonable.

This series adds #clock-cells to the jz4780 and fixes the device tree for
the CI20. It contains two ugly workarounds since BL_WAKE and WL_WAKE can not
be controlled as shutdown-gpios or device-wakeup-gpios by the drivers.
We also update the power setup and sequencing and add a clock chain for
the 32 kHz clock.
Finally, we enable some required CONFIGs for the CI20.

Tested on CI20 with v6.2-rc6.

H. Nikolaus Schaller (3):
  MIPS: DTS: jz4780: add #clock-cells to rtc_dev
  MIPS: DTS: CI20: fixes for WiFi/Bluetooth
  MIPS: configs: ci20: enable drivers we need for WiFi/Bluetooth
