[PATCH v4 0/3] drm_of_encoder_active_endpoint helpers
by Philipp Zabel 30 Jan '16

30 Jan '16

Hi, these are rebased onto v4.5-rc1 and the rockchip patch is updated to also replace the rockchip_drm_encoder_get_mux_id() call in dw-mipi-dsi.c. The first two patches are unchanged, I'm just looking for feedback whether I should include the rockchip patch in the next imx-drm pull request. Changes since v3: - Rebased onto v4.5-rc1, - also update dw-mipi-dsi from rockchip_drm_encoder_get_mux_id() to drm_of_encoder_active_endpoint(). regards Philipp Philipp Zabel (3): drm: add drm_of_encoder_active_endpoint helpers drm/imx: remove imx_drm_encoder_get_mux_id drm/rockchip: remove rockchip_drm_encoder_get_mux_id drivers/gpu/drm/drm_of.c | 34 +++++++++++++++++++++++++++++ drivers/gpu/drm/imx/dw_hdmi-imx.c | 2 +- drivers/gpu/drm/imx/imx-drm-core.c | 30 ------------------------- drivers/gpu/drm/imx/imx-drm.h | 2 -- drivers/gpu/drm/imx/imx-ldb.c | 5 +++-- drivers/gpu/drm/rockchip/dw-mipi-dsi.c | 2 +- drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c | 2 +- drivers/gpu/drm/rockchip/rockchip_drm_drv.c | 30 ------------------------- drivers/gpu/drm/rockchip/rockchip_drm_drv.h | 2 -- include/drm/drm_of.h | 32 +++++++++++++++++++++++++++ 10 files changed, 72 insertions(+), 69 deletions(-) -- 2.7.0.rc3

[PATCH v5 00/14] ASoC: hdac_hdmi: Add DP & notification support
by Subhransu S. Prusty 30 Jan '16

30 Jan '16

This patch series adds DP audio and hotplug notification support. In skylake platform the DP is on a different port which is not enabled by default. A vendor widget is programmed to enable playback on all ports. This also enables all the converters. Codec Dais, widgets, graph are now created dynamically based on the nodes enumerated, thus removing the hardcoding. Mux controls are used to establish routing stream to a specific port. For DP audio support, infoframe needs to be different. Based on ELD queried we either pack HDMI or DP infoframe. Also with this series, Jack notification support is added and Jack event is reported to userspace as is done in case of legacy driver. Few fixes are added to check for possible memory leak, reconfiguring register during resume from D3 etc. The 8th patch is adding a small macro for getting connection type in drm header. It is reviewed by drm folks, CCed them. Please merge it through sound trees. Changes in v5: - Added more comments and reworded some commit messages - Jack reporting support to user space added - Fix to check for possible memory leak in hw_params - Fix not to fail in dai startup to make userland APIs happy Cc: Jani Nikula <jani.nikula(a)intel.com> Cc: David Airlie <airlied(a)linux.ie> Cc: dri-devel(a)lists.freedesktop.org Cc: Daniel Vetter <daniel.vetter(a)intel.com> Jeeja KP (2): ASoC: hdac_hdmi: Add jack reporting ASoC: hdac_hdmi: Add PM support Ramesh Babu (1): ASoC: hdac_hdmi: Fix to keep codec power active during enumeration.

Exynos Snow board display regression
by Michal Suchanek 29 Jan '16

29 Jan '16

Hello, after commit a9fa852886fd5a7ccec3b7e9eff75f85072f009c display no longer works on the Snow board. The built-in panel is no longer probed. The commit *supposedly* provides for backwards compatibility and at first glance only new options for probing the panel are added. However, reverting the commit on top of 4.5-rc1 gives working display again so there is probably some subtle non-obvious catch in the logic. Any ideas what might go wrong here? Thanks Michal Author: Inki Dae <inki.dae(a)samsung.com> Date: Thu Nov 26 21:34:18 2015 +0900 drm/exynos: dp: add of_graph dt binding support for panel This patch adds of_graph dt binding support for panel device and also keeps the backward compatibility. i.e., The dts file for Exynos5800 based peach pi board has a panel property so we need to keep the backward compatibility. Changelog v3: - bind only one of two nodes outbound - panel or bridge. Changelog v2: - return -EINVAL if getting a port node failed.

[PATCH 00/11] sync framework de-staging: part 1 - clean up

From: Gustavo Padovan <gustavo.padovan(a)collabora.co.uk> Hi, The following patches are some clean ups on the sync framework before we start the actual de-staging. The main changes here are the move of SW_SYNC_USER to debugfs. Removal of struct sync_pt in favor of direct use of struct fence. And the rename of sync_fence to sync_file, a name to better reflect what it is for, a struct that connects struct fence(s) to a file. Please review. Thanks.
