043652aa3d drm/panel: Add driver for Seiko 43WVF1G panel
Add driver for Seiko Instruments Inc. 4.3" WVGA (800 x RGB x 480)
TFT with Touch-Panel.

Datasheet available at:
http://www.glyn.de/data/glyn/media/doc/43wvf1g-0.pdf

Seiko 43WVF1G panel has two power supplies: avdd and dvdd and they
require a specific power on/down sequence.
For this reason the simple panel driver cannot be used to drive this
panel, so create a new one heavily based on simple panel.

Based on initial patch submission from Breno Lima.

f0a5bb9803 drm/panel: Add support for OTM8009A panel driver
This patch adds Orise Tech OTM8009A 3.97" 480x800 TFT LCD
panel driver (MIPI-DSI video mode). The panel backlight is
managed through the DSI link. This panel driver is used in
several STM32 boards.

50d5ed3992 drm/panel: make DRM_PANEL_LD9040 depend on SPI
Rather than DRM_PANEL_LD9040 selecting SPI, which then results in an
increase in the probability of Kconf reporting circular dependencies
(we're one "select" away from that right now), make this depend on
SPI instead.  This is akin to having some driver select DRM.

Having some drivers depend on a subsystem, and other drivers select a
subsystem is a recipe for circular dependencies, and there's really no
need for it.

The potential circular dependency (which can be caused today by the
addition of selecting DRM_PANEL from DRM_IMX_LDB) is:

  symbol DMADEVICES is selected by SAMSUNG_DMADEV
  symbol SAMSUNG_DMADEV is selected by S3C64XX_PL080
  symbol S3C64XX_PL080 is selected by SPI_S3C64XX
  symbol SPI_S3C64XX depends on SPI
  symbol SPI is selected by DRM_PANEL_LD9040
  symbol DRM_PANEL_LD9040 depends on DRM_PANEL
  symbol DRM_PANEL is selected by DRM_IMX_LDB
  symbol DRM_IMX_LDB depends on MFD_SYSCON
  symbol MFD_SYSCON is selected by POWER_RESET_KEYSTONE
  symbol POWER_RESET_KEYSTONE depends on POWER_SUPPLY
  symbol POWER_SUPPLY is selected by HID_SONY
  symbol HID_SONY depends on NEW_LEDS
  symbol NEW_LEDS is selected by BACKLIGHT_ADP8860
  symbol BACKLIGHT_ADP8860 depends on BACKLIGHT_CLASS_DEVICE
  symbol BACKLIGHT_CLASS_DEVICE is selected by FB_MX3
  symbol FB_MX3 depends on MX3_IPU

DRM_PANEL_LD9040 and DRM_PANEL_S6E8AA0 both explicitly depended on
DRM_PANEL && DRM, whereas DRM_PANEL_SIMPLE relies upon the dependency

We do not need to use explicit dependencies if we make the menu depend

depend on DRM_PANEL && DRM without this needing to be explicitly stated
against every entry.

aead40ea0b drm: Add panel support
Add a very simple framework to register and lookup panels. Panel drivers
can initialize a DRM panel and register it with the framework, allowing
them to be retrieved and used by display drivers. Currently only support
for DPMS and obtaining panel modes is provided. However it should be
sufficient to enable a large number of panels. The framework should also
be easily extensible to support more sophisticated kinds of panels such
as DSI.

The framework hasn't been tied into the DRM core, even though it should
be easily possible to do so if that's what we want. In the current
implementation, display drivers can simple make use of it to retrieve a
panel, obtain its modes and control its DPMS mode.

Note that this is currently only tested on systems that boot from a
device tree. No glue code has been written yet for systems that use
platform data, but it should be easy to add.
