Add remaining IO expansions on Lichee Pi 4A

[PATCH v2 0/5] Add remaining IO expansions on Lichee Pi 4A

Posted by Icenowy Zheng 1 week, 4 days ago

This patchset is split off the "Add TH1520 USB support" patchset,
dedicating to enable the IO expansion chips, because the situation
becomes complex when one of them (but not all) was added for Wi-Fi
support.

I fixed a small issue of the existing I2C1 device node, and then all
original patches are aligned with the existing I2C1 node for
consistency.

Emil Renner Berthing (2):
  riscv: dts: thead: Add IO labels for the IO expansion on I2C1
  riscv: dts: thead: Add remaining Lichee Pi 4A IO expansions

Icenowy Zheng (2):
  riscv: dts: thead: th1520: remove pclk for I2C1
  riscv: dts: thead: lpi4a: sort nodes

Thomas Bonnefille (1):
  riscv: dts: thead: Add TH1520 I2C nodes

I have applied all 5 patches to thead-dt-for-next and they are now in
linux-next:

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/log/arch/riscv/boot/dts/thead

If no problems arise, then I will send thead-dt PR for 7.3 in a few days.

Thanks,
Drew
