2014-04-03ENGR00306875-2 video: mxc_hdmi: Set hdmi cable state a bit earilierNicolin Chen
During hdmi hotplug test, there's a possibility that X-server unblanks the frame buffer while HDMI-audio just gets the signal to start playback. Then audio would get an unblanked state right before the playback and bypassed the DMA enabling code. So this issue is caused by the race between unblank and set_cable_state(). This patch sets the hdmi cable state a bit earilier so as to let audio play first. If unblank happens later, the hdmi core and hdmi audio would be robust enough to handle that case as long as it's not racing with the other parts.

2014-03-17ENGR00303663 mxc v4l2 capture: Don't return error if we cannot get mipi csi2Liu Ying
The mipi csi2 code is ugly present in the capture pipeline setup/disable routions with '#ifdef CONFIG_MXC_MIPI_CSI2/#endif' protected. Whenever it finds mipi_csi2_info is not gotten correctly, it will return error to callers. This breaks the normally routines in which mipi csi2 is not used and mipi csi2 driver is disabled in its devicetree node(but with the Kconfig CONFIG_MXC_MIPI_CSI2 defined). A real example is the capture feature on the MX6 Sabreauto platforms. We have only parallel CSI input on it and the mipi csi2 driver is disabled in its devicetree node but with the Kconfig CONFIG_MXC_MIPI_CSI2 defined. So, a reasonable choice at present is not to return error if mipi_csi2_info cannot be gotten, though we could eventually re-organize the capture code for a better total solution in the future.

2014-03-17ENGR00303308 hdmi:update default video mode setting required by xserverSandor Yu
xserver will read default video mode in command line by sysfs node /sys/class/graphics/fb0/mode, but the sysfs node is not initialized when system bootup without hdmi cable plugin or frame buffer register in blank state. Fixed: - Remove unused previous_mode - Add default_mode, initialize in disp_init function. - Initialize fbi->mode in disp_init function and hdmi_setup function.

commit f8e1a3bb62eecf93a31a51c4dbe08a0214fa1d57 introduced an annoying kernel log by changing a pure debug info to error level. This patch reverts that change.

2014-03-17ENGR00243315-3 MXC V4L2 Capture:Remove unnecessary mclk settingLiu Ying
commit f8e1a3bb62eecf93a31a51c4dbe08a0214fa1d57 added a hard coding for csi_parma.mclk setting to 27MHz. The comment added by that commit is totally wrong by telling that csi_param.mclk would be a kind of 'pixel clock' set in 'csi_data_dest' register. This patch removes the unnecessary mclk setting for csi_param.mclk variable, since it is only valid for CSI test mode.
