drm/mediatek: Add ovl_adaptor support for MT8195

2023-03-22T16:25:16+00:00

Add ovl_adaptor driver for MT8195. Ovl_adaptor is an encapsulated module and designed for simplified DRM control flow. This module is composed of 8 RDMAs, 4 MERGEs and an ETHDR. Two RDMAs merge into one layer, so this module support 4 layers.

drm/mediatek: Add ETHDR support for MT8195

2023-03-22T16:25:00+00:00

ETHDR is a part of ovl_adaptor. ETHDR is designed for HDR video and graphics conversion in the external display path. It handles multiple HDR input types and performs tone mapping, color space/color format conversion, and then combine different layers, output the required HDR or SDR signal to the subsequent display path.

drm/mediatek: Add MT8195 Embedded DisplayPort driver

2022-09-04T12:32:05+00:00

This patch adds a embedded displayport driver for the MediaTek mt8195 SoC. It supports the MT8195, the embedded DisplayPort units. It offers DisplayPort 1.4 with up to 4 lanes. The driver creates a child device for the phy. The child device will never exist without the parent being active. As they are sharing a register range, the parent passes a regmap pointer to the child so that both can work with the same register range. The phy driver sets device data that is read by the parent to get the phy device that can be used to control the phy properties. This driver is based on an initial version by Jitao shi Signed-off-by: Markus Schneider-Pargmann Signed-off-by: Guillaume Ranquet Signed-off-by: Bo-Chen Chen Reviewed-by: CK Hu Tested-by: AngeloGioacchino Del Regno Reviewed-by: AngeloGioacchino Del Regno Signed-off-by: Dmitry Osipenko Link: https://patchwork.freedesktop.org/patch/msgid/20220901044149.16782-4-rex-bc.chen@mediatek.com
