drm/panel: Add Kingdisplay KD097D04 panel driver
Support Kingdisplay KD097D04 9.7" 1536x2048 TFT LCD panel, it is a MIPI
dual-DSI panel.
v4-resend:
- Thierry noted missing dt-bindings for v4 but forgot that he
already had applied them one kernel release back in
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ebc950fdff6d5f9250cd5a5a348af97f7d8508df
v4:
- address Philipp's comments
- real range for usleep_range and
- poweroff ordering in kingdisplay_panel_prepare
- return value beautification in panel_probe
- update author naming for full name
v3:
- address Thierry's comments
- error handling for init dsi writes in init
- unconditionally remove the panel
- don't use drm_panel_detach
- a bit of variable signednes wiggling
- I did talk to ChromeOS people and the delays really should be as short
as possible, so dropped the 100ms from the delay comments
v2:
- update timing + cmds from chromeos kernel
- new backlight API including switch to devm_of_find_backlight
- fix most of Sean Paul's comments
enable/prepare tracking seems something all panels do
- document origins of the init sequence
- lanes per dsi interface to 4 (two interfaces). Matches how tegra
and pending rockchip dual-dsi handle (dual-)dsi lanes
- spdx header instead of license boilerplate
