The Snapdragon Lenovo T14s Gen6 can be bought with a number of different
panels. This patch series adds support for the OLED model which has a
Samsung ATNA40YK20 panel.

With this patch series the backlight of the OLED eDP panel does not
illuminate since the brightness is incorrectly read from the eDP panel
as (to be clear this is not a regression). This is fixed in [0].

It would be good to get OLED support for the T14s merged. Are you
planning on sending another revision of this series?
No reply for over a month. Do you intend to respin these or should
someone else take over?

Neil, do you have the OLED version now?
I'm not sure, how do I determine that ? Is there something specific in the type number ?
Yes, yours is the OLED version, the exact models stated above.
Ack thx, I'll test and re-spin this patchset then.
Sorry for the delay. I've just sent a v5 of this patch. I will look at
the eDP brightness patch next...

Strictly speaking you could have posted this last patch on it's own as
it doesn't depend on adding the hpd pinctrl.
