[PATCH 00/10] ARM: dts: rockchip: enable edp functionality

[Heiko Stuebner]

This is the companion series to Yakir's rework of the analogix-dp
driver used both by Exynos and Rockchip.

These patches have been sitting in my tree for some time, and already
got tested (and thus refined) by a number of people.

So I'll post them now, to get applied after the driver-side gets
accepted hopefully soonish.

[PATCH 03/10] ARM: dts: rockchip: move edp-hpd pin definition into common location

[Heiko Stuebner]

The edp hotplug pin is fixed on the soc side, anybody wanting to use it
will need the same definition anyway, so move it to a common location.

[PATCH 04/10] ARM: dts: rockchip: add startup delay to rk3288-veyron panel-regulators

[Heiko Stuebner]

The panels need a bit of time to actually turn on. If this isn't
observed, this results in problems when trying talk to the panels
and thus produces detection errors. 100ms seem to be a safe value
for the time being.

[PATCH 05/10] ARM: dts: rockchip: add core rk3288-veyron backlight and panel nodes

Many Veyron chromebooks share the same panel type, so define the core
settings for all of them and allow the few runaways to override it later.

[PATCH 06/10] ARM: dts: rockchip: add rk3288-veyron-jaq backlight and panel overrides

[Heiko Stuebner]

From: Caesar Wang <wxt-TNX95d0MmH7DzftRWevZcw@public.gmane.org>

The panel which jaq uses requires the pwm duty cycle larger than 3%,
when the backlight status from power off to power on, otherwise the
backlight will flush, so we modify the second brightness-level to 8,
and when the backlight from power off to power on the pwm duty cycle
will larger than 3%.

[PATCH 07/10] ARM: dts: rockchip: add rk3288-veyron-minnie backlight and panel settings

[Heiko Stuebner]

The pwm for Minnie's backlight needs to be above 1%, so adapt the start
of non-zero brightness accordingly. Minnie is also using a different
panel, so re-set the compatible property.

[PATCH 08/10] ARM: dts: rockchip: override edp hpd handling on veyron-pinky and speedy

[Heiko Stuebner]

Pinky boards don't have the hotplug pin connected. So remove the
hotplug pinctrl setting and enable the force-hpd option, to allow
them to find the display too.

While on speedy boards, the hotplug pin is connected, judging by comments
in a chromeos change it seems the "panels HPD voltage is too low to be
detected", so it also needs the forced hotplug, as we of course also know
that a display is connected.

Awesome!  I picked this along with the eDP series and I was able to
use the builtin panel on my veyron-jerry.  :)  I was testing on a
4.4-based tree with backports.

with the edp driver entering the drm tree for 4.7, I've now applied the dt-
