Merge omapdss public header refactoring, which separates the public
header into omapdrm and omapfb parts.
|
|
To allow supporting displays that need some logic to enable power to the
display try to get a vcc-supply property from the device tree and drive
the resulting regulator accordingly.

Some displays have a reset input. To assert that the display is
functional the reset gpio must be deasserted.
Teach the driver to get and drive such a gpio accordingly.

All drivers to include the omapdrm/dss/omapdss.h header file. This header
includes the <video/omapdss.h>

A lot of the display drivers for OMAP use the gpio descriptor functions
that are only available in linux/gpio.h if GPIOLIB is enabled and
otherwise produce a build error:
drivers/gpu/drm/omapdrm/displays/encoder-opa362.c: In function 'opa362_enable':
drivers/gpu/drm/omapdrm/displays/encoder-opa362.c:101:3: error: implicit declaration of function 'gpiod_set_value_cansleep' [-Werror=implicit-function-declaration]
drivers/gpu/drm/omapdrm/displays/panel-dpi.c: In function 'panel_dpi_probe_pdata':
drivers/gpu/drm/omapdrm/displays/panel-dpi.c:189:23: error: implicit declaration of function 'gpio_to_desc' [-Werror=implicit-function-declaration]

This replaces the existing linux/gpio.h with linux/gpio/consumer.h
where needed. In case of panel-lgphilips-lb035q02.c however, we
also have to include linux/gpio.h to get the definition of gpio_is_valid
and gpio_set_value_cansleep that are used for the non-DT case.

With certain kernel config options many omapdrm files fail to compile
due to missing include of linux/gpio/consumer.h and linux/of.h.
This patch adds those includes.

Now that omapfb has its own copy of omapdss and display drivers, we can
move omapdss and display drivers which omapdrm uses to omapdrm's
directory.
We also need to change the main drm Makefile so that omapdrm directory
is always entered, because omapdss has a file that can't be built as a
module.
