[PATCH v2 0/2] drm/panel: Add support for TSD TST070WSBE-196C 8" MIPI-DSI panel

[William Bright]

This series adds support for the TSD TST070WSBE-196C, a 7" 1024x600                                                                   
MIPI-DSI TFT LCD panel module based on the Fitipower EK79007AD                                                                        
controller. The panel is connected over a 4-lane MIPI-DSI video-mode                                                                  
interface and uses the RGB888 pixel format.                                                                                           
                                                                                                                                        
The driver is a simple non-configurable panel: the EK79007AD comes up                                                                 
with usable defaults after the power/reset sequence, so no                                                                 
DCS init sequence is required. It supports a single power supply, a                                                                   
reset GPIO and the standard backlight framework.

Note that in patch 2, link [2] has the incorrect DTSI name 
(TST070WSBE-165C.dtsi instead of TST070WSBE-196C.dtsi) even though 
its for the same panel as this patchset.
   
Patch 1 adds the dt-binding for the panel.                                                                                            
Patch 2 adds the panel driver, Kconfig/Makefile entries and a                                                                       
MAINTAINERS entry.

Changes in v2:
- As suggested by Dmitry, rework patch 1 and 2 so that the 
  panel-simple driver is modified instead of creating a new custom 
  driver for the panel since the panel doesn't require programming 
  via DSI.
- The panel controller (EK79007AD) supports 
  MIPI_DSI_MODE_VIDEO_BURST and
  MIPI_DSI_MODE_VIDEO_SYNC_PULSE. These have been added to the
  panel-desc flags.
- Rework patch 1 and 2 to rename the panel vendor as 
  Team Source Display instead of using the shortened version (TSD).
- Within the timing table, the pixel clock is now given 
  as an explict value instead of a calculated value
  to be similar to the other panels defined in simple-panel.

[PATCH v2 2/2] drm/panel: simple: Add Team Source Display TST070WSBE-196C panel

[William Bright]

Add a dedicated panel driver for the Team Source Display
TST070WSBE-196C, a 7" 1024x600 MIPI-DSI TFT LCD panel
using an EK79007AD controller.

The DSI timings were calculated using
"linux-mdss-dsi-panel-driver-generator" [1], reading the downstream
file "dsi-panel-imdt-tst070wsbe165c-video.dtsi" [2].
