Those look good to me as well. I'd say just apply them.

To me it looks like up until and including patch 18?
Feel free to add my

On these.

It looks good to me so I sent an explicit ACK on that patch.

I dare not speak of this. Laurent has the long and tedious experience
with panels and pretty much anything related so if Laurent is
hesitant then I am hesitant too. His buy-in is absolutely required.

But IIUC that is just for patch 19+20?

It'd be good to apply the rest and get down the stack.

Just to keep you busy and make sure you don't run out of work
(haha) I noticed that the gpio_chip in this driver can use
the new GPIO_REGMAP helper library with the fixes just
landed in Torvald's tree.

At your convenience and when you think there is too little
stuff in your sn65dsi86 TODO, check out
pinctrl-bcm63xx.c for an example of select GPIO_REGMAP
made very simple (this works fine as long as they are bit
offsets starting from 0).

Yours,
Linus Walleij
