Merge tag 'v6.14-rc4' into drm-next
Backmerge Linux 6.14-rc4 at the request of tzimmermann so misc-next
can base on rc4.

This driver uses the enable-gpios property and it is confusing that the
error message refers to reset-gpios. Use the correct name when the
enable GPIO is not found.

In jadard_prepare() a reset pulse is generated with the following
statements (delays ommited for clarity):
gpiod_set_value(jadard->reset, 1); --> Deassert reset
gpiod_set_value(jadard->reset, 0); --> Assert reset for 10ms
gpiod_set_value(jadard->reset, 1); --> Deassert reset
However, specifying second argument of "0" to gpiod_set_value() means to
deassert the GPIO, and "1" means to assert it. If the reset signal is
defined as GPIO_ACTIVE_LOW in the DTS, the above statements will
incorrectly generate the reset pulse (inverted) and leave it asserted
(LOW) at the end of jadard_prepare().
Fix reset behavior by inverting gpiod_set_value() second argument
in jadard_prepare(). Also modify second argument to devm_gpiod_get()
in jadard_dsi_probe() to assert the reset when probing.
Do not modify it in jadard_unprepare() as it is already properly
asserted with "1", which seems to be the intended behavior.

The Lenovo Thinkpad T14s Gen6 Snapdragon is currently sold with three
different panel versions: OLED, Low Power IPS or IPS with Touchscreen.
My Low Power IPS version had this panel and the kernel complained
about not knowing any details. I don't have any panel documentation,
but as far as I can see the same timings for the already supported
CSO panel also work for this one.
The raw EDID is:

We have a few reports of sc7180-trogdor-pompom devices that have a

We've been unable to locate a datasheet for this panel and our partner
has not been responsive, but all Starry eDP datasheets that we can
find agree on the same timing (delay_100_500_e200) so it should be
safe to use that here instead of the super conservative timings. We'll
still go a little extra conservative and allow `hpd_absent` of 200
instead of 100 because that won't add any real-world delay in most
cases.
We'll associate the string from the EDID ("116KHD024006") with this
panel. Given that the ID is the suspicious value of 0x0004 it seems
likely that Starry doesn't always update their IDs but the string will
still work to differentiate if we ever need to in the future.

The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.
