Organization: Wires
Add MEDIA_BUS_FMT_RGB101010_1X7X5_{JEIDA,SPWG} support in
drm_of_lvds_get_data_mapping() function implementation so that function
callers may get the two LVDS data mappings.

+
+description: |
+ The IT6263 is a high-performance single-chip De-SSC(De-Spread Spectrum) LVDS
+ to HDMI converter. Combined with LVDS receiver and HDMI 1.4a transmitter,
+ the IT6263 supports LVDS input and HDMI 1.4 output by conversion function.
+ The built-in LVDS receiver can support single-link and dual-link LVDS inputs,
+ and the built-in HDMI transmitter is fully compliant with HDMI 1.4a/3D, HDCP
+ 1.2 and backward compatible with DVI 1.0 specification.
+
+ The IT6263 also encodes and transmits up to 8 channels of I2S digital audio,
+ with sampling rate up to 192KHz and sample size up to 24 bits. In addition,
+ an S/PDIF input port takes in compressed audio of up to 192KHz frame rate.
+
+ The newly supported High-Bit Rate(HBR) audio by HDMI specifications v1.3 is
+ provided by the IT6263 in two interfaces: the four I2S input ports or the
+ S/PDIF input port. With both interfaces the highest possible HBR frame rate
+ is supported at up to 768KHz.

Subject: [PATCH 33/35] drm/bridge: Add ITE IT6263 LVDS to HDMI converter
Organization: Wires
Add basic HDMI video output support. Currently, only RGB888 output
pixel format is supported. At the LVDS input side, the driver
supports single LVDS link and dual LVDS links with "jeida-24" LVDS
mapping.

Subject: [PATCH 34/35] drm/bridge: ite-it6263: Support VESA-24 input format
Organization: Wires
Introduce it6263_is_input_bus_fmt_valid() and refactor the
it6263_bridge_atomic_get_input_bus_fmts() function to support VESA-24
format by selecting the LVDS input format based on the LVDS data mapping
and thereby support both JEIDA-24 and VESA-24 input formats.

dereference in probe()
Organization: Wires
If devm_i2c_new_dummy_device() fails then we were supposed to return an
error code, but instead the function continues and will crash on the next
line. Add the missing return statement.
