Subject: [PATCH 0/5] drm/i915/dsi: Control panel and backlight enable GPIOs from VBT
Date: Sun, 15 Dec 2019 17:38:05 +0100	[thread overview]
Message-ID: <20191215163810.52356-1-hdegoede@redhat.com> (raw)

Hi All,

This is a new (completely rewritten) version of my patches to make the
i915 code control the SoC panel- and backlight-enable GPIOs on Bay Trail
devices when the VBT indicates that the SoC should be used for backlight
control. This fixes the panel not lighting up on various devices when
booted with a HDMI monitor connected, in which case the firmware skips
initializing the panel as it inits the HDMI instead.

This series has been tested on; and fixes this issue on; the following models:

Peaq C1010
Point of View MOBII TAB-P800W
Point of View MOBII TAB-P1005W
Terra Pad 1061
Thundersoft TST178
Yours Y8W81

Linus, this series starts with the already discussed pinctrl change to
export the function to unregister a pinctrl-map. We can either merge this
through drm-intel, or you could pick it up and then provide an immutable
branch with it for merging into drm-intel-next. Which option do you prefer?

Lee, I know you don't like this, but unfortunately this series introcudes
some (other) changes to drivers/mfd/intel_soc_pmic_core.c. The GPIO subsys
allows only one mapping-table per consumer, so in hindsight adding the code
which adds the mapping for the PMIC panel-enable pin to the PMIC mfd driver
was a mistake, as the PMIC code is a provider where as mapping-tables are
per consumer. The 4th patch fixes this by moving the mapping-table to the
i915 code, so that we can also add mappings for some of the pins on the SoC
itself. Since this whole series makes change to the i915 code I plan to
merge this mfd change to the drm-intel tree.

Regards,

Hans
