Re: [PATCH v3 0/3] Novatek NT51021 DSI panel IC driver

[Ryan Brue]

Tested-by: Ryan Brue <ryanbrue.dev@xxxxxxxxx> # Amazon Fire HD 10 
(2017), boe,tv101wum-nm0

On the CABC teardown for the nm0 variant that Sashiko found: the write 
is a single DSI generic command to the panel IC just before it is 
powered off, so there is nothing on I2C for it to collide with (the 
LP8557 backlight is a different device and is already off by then). On 
the Fire HD 10 the full disable/unprepare then prepare/enable path runs 
on every DPMS cycle and system suspend, and the panel comes back cleanly 
every time. Skipping the call for variants that never turn CABC on would 
be tidier, though, and I am fine either way; I'll let it be your call 
Nickolay. Thanks for pulling in my patches!
