drm/dp/mst: make mst i2c transfer code more robust.

2015-10-14T23:06:20Z

This zeroes the msg so no random stack data ends up getting sent, it also limits the function to not accepting > 4 i2c msgs. Cc: stable@vger.kernel.org Reviewed-by: Daniel Vetter Signed-off-by: Dave Airlie

drm/dp/mst: split connector registration into two parts (v2)

2015-10-02T05:34:41Z

In order to cache the EDID properly for tiled displays, we need to retrieve it before we register the connector with userspace, otherwise userspace can call get resources and try and get the edid before we've even cached it. This fixes some problems when hotplugging mst monitors, with X/mutter running. As mutter seems to get 0 modes for one of the monitors in the tile. v2: fix warning in radeon handle tile setting in cached path rather than get edid path.

drm: Add a non-locking version of drm_kms_helper_poll_enable(), v2

2015-09-30T13:04:08Z

drm_kms_helper_poll_enable() was converted to lock the mode_config mutex in commit 8c4ccc4ab6f64e859d4ff8d7c02c2ed2e956e07f ("drm/probe-helper: Grab mode_config.mutex in poll_init/enable"). This disregarded the cases where this function is called from a context where this mutex is already locked. Add a non-locking version as well. Changes since v1: - use function name suffix '_locked' for the function that is to be called from a locked context. Signed-off-by: Egbert Eich Reviewed-by: Daniel Vetter Signed-off-by: Jani Nikula

drm/i915: Drop port_mst_index parameter from pin/eld callback

2015-09-03T10:09:03Z

The port_mst_index parameter was reserved for future use, but maintainers prefer to add it later when it is actually used. [Note: this is an update patch to commit [51e1d83cab99: drm/i915: Call audio pin/ELD notify function] where I mistakenly applied the older version.

drm/i915: Add audio pin sense / ELD callback

2015-09-02T09:30:44Z

This callback will be called by the i915 driver to notify the hda driver that its HDMI information needs to be refreshed, i e, that audio output is now available (or unavailable) - usually as a result of a monitor being plugged in (or unplugged).

Merge branch 'drm-dwhdmi-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into drm-next

2015-08-27T03:01:57Z

Here are some development updates for the Synopsis Designware HDMI driver, which clean up some of the code, and start preparing to add audio support to the driver. This series of patches are based on a couple of dependent commits from the ALSA tree. Briefly, the updates are: - move comments which should have moved with the phy values to the IMX part of the driver. - clean up the phy configuration: to all lookups before starting to program the phy. - clean up the HDMI clock regenerator code - use the drm_hdmi_avi_infoframe_from_display_mode() helper which allows the code to be subsequently simplified - remove the unused 'regmap' pointer in struct dw_hdmi - use the bridge drm device rather than the connector (we're the bridge code) - remove private hsync/vsync/interlaced flags, getting them from the DRM mode structure instead. - implement interface functions to support audio - setting the audio sample rate, and enabling the audio clocks. - removal of broken pixel repetition support - cleanup DVI vs HDMI sink handling - enable audio only if connected device supports audio - avoid double-enabling bridge in the sink path (once in mode_set, and again in commit) - rename mis-named dw_hdmi_phy_enable_power() - fix bridge enable/disable handing, so a plug-in event doesn't reconfigure the bridge if DRM has disabled the output - fix from Vladimir Zapolskiy for the I2CM_ADDRESS macro name These are primerily preparitory patches for the AHB audio driver and the I2S audio driver (from Rockchip) for this IP. * 'drm-dwhdmi-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: drm: bridge/dw_hdmi: fix register I2CM_ADDRESS register name drm: bridge/dw_hdmi: fix phy enable/disable handling drm: bridge/dw_hdmi: rename dw_hdmi_phy_enable_power() drm: bridge/dw_hdmi: avoid enabling interface in mode_set drm: bridge/dw_hdmi: enable audio only if sink supports audio drm: bridge/dw_hdmi: clean up HDMI vs DVI mode handling drm: bridge/dw_hdmi: don't support any pixel doubled modes drm: bridge/dw_hdmi: remove pixel repetition setting for all VICs drm: bridge/dw_hdmi: introduce interfaces to enable and disable audio drm: bridge/dw_hdmi: introduce interface to setting sample rate drm: bridge/dw_hdmi: remove mhsyncpolarity/mvsyncpolarity/minterlaced drm: bridge/dw_hdmi: use our own drm_device drm: bridge/dw_hdmi: remove unused 'regmap' struct member drm: bridge/dw_hdmi: simplify hdmi_config_AVI() a little drm: bridge/dw_hdmi: use drm_hdmi_avi_infoframe_from_display_mode() drm: bridge/dw_hdmi: clean up hdmi_set_clk_regenerator() drm: bridge/dw_hdmi: clean up phy configuration drm: imx/dw_hdmi: move phy comments drm/edid: add function to help find SADs
