Merge tag 'drm-misc-next-2024-11-08' of https://gitlab.freedesktop.org/drm/misc/kernel into drm-next
drm-misc-next for v6.13: UAPI Changes: - Add 1X7X5 media-bus formats. Cross-subsystem Changes: - Maintainer updates for VKMS and IT6263. - Add media-bus-fmt for MEDIA_BUS_FMT_RGB101010_1X7X5_*. - Add IT6263 DT bindings and driver. Core Changes: - Add ABGR210101010 support to panic handler. - Use ATOMIC64_INIT in drm_file.c - Improve scheduler teardown documentation. Driver Changes: - Make mediatek compile on ARM again. - Add missing drm/drm_bridge.h header include, already in drm-next. - Small fixes and cleanups to vkms, bridge/it6505, panfrost, panthor. - Add panic support to nouveau for nv50+.

+title: ITE IT6263 LVDS to HDMI converter
+
+maintainers:
+ - Liu Ying <victor.liu@nxp.com>
+
+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.
