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.
