Hi Chris,

Never use hotmail.com for sending patches.
They corrupt Message-ID, so use for example Gmail.

X-Microsoft-Original-Message-ID:
 <20210419155718.17348-3-macromorgan@xxxxxxxxxxx>

Message-ID:
<SN6PR06MB53420A0E831C17342A73188BA5499@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>

====

If you like rk817.txt should be converted to YAML, which is beyond your
serie, so move these changes to rk817.txt instead for now if rob+dt
agrees. ;)

====

Include the dts patch back in, so we can compare it with the
documentation changes.

If you want to convert rk817.txt to rockchip,rk817.yaml then add

maintainers:
  - Heiko Stuebner <heiko@xxxxxxxxx>

Move things with "#" below as much as possible.

This is part of a sub node now.

Add compatible "rockchip,rk817" to properties

Without rockchip,rk817.yaml this example will generate notifications.

add include for IRQ_TYPE_LEVEL_LOW

Move things with "#" down below the list in possible.

add include for SCLK_I2S_8CH_OUT

Heiko's sort rules:

compatible
reg
interrupts
[alphabetical]
status [if needed]

Move to rk817.txt example.

Never use status in examples.
