[PATCH v6 0/5] Enable rk3066a HDMI sound
by Johan Jonker 22 Mar '21

22 Mar '21

Update the rk3066a HDMI documents with a #sound-dai-cells property. Include the code for sound in the HDMI driver. Add a simple-sound-card compatible node to rk3066a.dtsi, because I2S0 and HDMI TX are connected internally. And as last enable rk3066a HDMI sound in the rk3066a-mk808.dts file. make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- -j4 cp ./arch/arm/boot/zImage ../zImage-dtb cat ./arch/arm/boot/dts/rk3066a-mk808.dtb >> ../zImage-dtb ../tools/rkcrc -k ../zImage-dtb ../mk808.… [View More]

[PATCH] RFC: i915: Drop relocation support on Gen12+
by Jason Ekstrand 12 Mar '21

12 Mar '21

The Vulkan driver in Mesa for Intel hardware never uses relocations if it's running on a version of i915 that supports at least softpin which all versions of i915 supporting Gen12 do. On the OpenGL side, Gen12 is only supported by iris which never uses relocations. The older i965 driver in Mesa does use relocations but it only supports Intel hardware through Gen11 and has been deprecated for all hardware Gen9+. The entire relocation UAPI and related infrastructure, therefore, doesn't have any … [View More]

[PATCH v5 0/7] drm: add simpledrm driver
by David Herrmann 12 Mar '21

12 Mar '21

Hey On request of Noralf, I picked up the patches and prepared v5. Works fine with Xorg, if configured according to: https://lists.freedesktop.org/archives/dri-devel/2014-January/052777.html If anyone knows how to make Xorg pick it up dynamically without such a static configuration, please let me know.

[PATCH v3 0/5] phy: phy-fsl-imx8-mipi-dphy: Add i.MX8qxp LVDS PHY mode support
by Liu Ying 08 Mar '21

08 Mar '21

Hi, This series adds i.MX8qxp LVDS PHY mode support for the Mixel PHY in the Freescale i.MX8qxp SoC. The Mixel PHY is MIPI DPHY + LVDS PHY combo, which can works in either MIPI DPHY mode or LVDS PHY mode. The PHY mode is controlled by i.MX8qxp SCU firmware. The PHY driver would call a SCU function to configure the mode. The PHY driver is already supporting the Mixel MIPI DPHY in i.MX8mq SoC, where it appears to be a single MIPI DPHY. Patch 1/5 sets PHY mode in the Northwest Logic MIPI … [View More]
