[PATCH 1/4] dt-bindings: display: simple: Document support for Innolux G121XCE-L01

[PATCH 1/4] dt-bindings: display: simple: Document support for Innolux G121XCE-L01

[Marek Vasut]

Document support for Innolux CheMei 12" G121XCE-L01 XGA LVDS display.

G121XCE-L01 is a Color Active Matrix Liquid Crystal Display composed of
a TFT LCD panel, a driver circuit, and LED backlight system. The screen
format is intended to support the 4:3, 1024(H) x 768(V) screen and either
262k/16.7M colors (RGB 6-bits or 8-bits) with LED backlight driver circuit.
All input signals are LVDS interface compatible.

Documentation [1] and [2] indicate that G121X1-L03 and G121XCE-L01 are
effectively identical panels, use the former as RGB 6-bits variant and
document the later as RGB 8-bits variant.

[PATCH 2/4] drm/panel: simple: Add missing Innolux G121X1-L03 format, flags, connector

[Marek Vasut]

The .bpc = 6 implies .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG ,
add the missing bus_format. Add missing connector type and bus_flags
as well.

Documentation [1] 1.4 GENERAL SPECIFICATI0NS indicates this panel is
capable of both RGB 18bit/24bit panel, the current configuration uses
18bit mode, .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , .bpc = 6.

Support for the 24bit mode would require another entry in panel-simple
with .bus_format = MEDIA_BUS_FMT_RGB666_1X7X4_SPWG and .bpc = 8, which
is out of scope of this fix.

[PATCH 3/4] drm/panel: simple: Convert Innolux G121X1-L03 to display_timing

[Marek Vasut]

Use display_timing instead of drm_display_mode to define a range of
possible display timings supported by this panel. This makes the panel
support more flexible and improves compatibility. No functional change
is expected.

The settings are picked from documentation [1] section 6.1 INPUT SIGNAL
TIMING SPECIFICATIONS.
