[PATCH -next] drm/nouveau/nv04: Use match_string() helper to simplify the code
by YueHaibing 06 Jan '20

06 Jan '20

match_string() returns the array index of a matching string. Use it instead of the open-coded implementation.

[PATCH resend 0/2] drm/connector: Add support for specifying panel_orientation on the kernel cmdline
by Hans de Goede 05 Jan '20

05 Jan '20

Hi All, This is a resend of the last 2 remaining patches of my series for adding support for specifying panel_orientation on the kernel cmdline. I've already pushed the other 11 patches which were mostly cleanups / bug-fixes to the cmdline-parsing code and where all acked by Maxime to drm-misc-next. The first patch of these 2 still needs to be reviewed, if someone can review it that would be great. Once this is reviewed the question becomes how to merge this, both patches are mostly drm-misc material and the second patch depends on the changes I just pushed to drm-misc-next, so this series should probably be pushed to drm-misc-next, but it also makes some changes to i915 code. I've checked and there is no conflict with these patches as they apply to drm-misc-next vs drm-intel-next-queued (atm). So it should be fine to push these 2 patches to drm-misc-next and then do a back-merge to drm-intel-next-queued. Regards, Hans

[PATCH v2 0/3] drm: Add support for Cadence MHDP DPI/DP bridge and J721E wrapper.
by Yuti Amonkar 04 Jan '20

04 Jan '20

This patch series adds new DRM driver for Cadence Display Port. The Cadence Display Port is also referred as MHDP (Mobile High Definition Link, High-Definition Multimedia Interface Display Port) Cadence Display Port complies with VESA DisplayPort (DP) and embedded Display Port (eDP) standards This driver implements Single Stream Transport (SST) support. Adds Texas Instruments SoC J721e specific wrapper and adds the device tree bindings in YAML format. The patch series has three patches which applies the changes in the below sequence 1. 001-dt-bindings-drm-bridge-Document-Cadence-MHDP-bridge-bindings-in-yaml-format Documents the bindings in yaml format. 2. 002-drm-bridge-Add-support-for-Cadence-MHDP-bridge This patch adds new DRM driver for Cadence MHDP Display Port. The patch implements supports for single stream transport mode. 3. 003-drm-mhdp-add-j721e-wrapper Add Texas Instruments (TI) j721e wrapper for mhdp. The wrapper configures mhdp clocks and muxes as required by SoC. Version History: v2: - Use enum in compatible property of YAML file. - Add reg-names property to YAML file - Add minItems and maxItems to reg property in YAML. - Remove cdns_mhdp_link_probe function to remove duplication of reading dpcd capabilities.

[PATCH v1 0/2] Add suppport for rm69299 Visionox panel driver and add devicetree bindings for visionox panel.
by Harigovindan P 04 Jan '20

04 Jan '20

Current patchset adds support for rm69299 visionox panel driver used in MSM reference platforms. The visionox panel driver supports a resolution of 1080x2248 with 4 lanes and supports only single DSI mode. Current patchset is tested on actual panel. Changes in v1: -add devicetree bindings for visionox panel. -Split out panel driver patch from dsi config changes(Rob Clark). -Remove unrelated code(Stephen Boyd). -Remove static arrays to make regulator setup open coded in probe(Stephen Boyd). -Remove pre-assigning variables(Stephen Boyd). -Inline panel_add function into probe(Stephen Boyd). -Use mipi_dsi_dcs_write directly(Rob Clark). -Remove qcom_rm69299_1080p_panel_magic_cmds array(Rob Clark).

[PATCH 1/2] drm/panel: Add DT bindings for Novatek NT35510-based panels
by Linus Walleij 04 Jan '20

04 Jan '20

This adds device tree bindings for the Novatek NT35510-based family of panels. Since several such panels are in existence we define bindings common for all, and define the compatible string for one certain panel (Hydis HVA40WV1). As other panels are discovered and investigated, we can add more compatibles to the binding.
