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