* | msm: mdss: esd recovery support for 8x10 targetsShivaraj Shetty2016-03-23
| | | | | | | | | | | | | | | | | | | | | | Add kernel side support for esd recovery for mdp3 targets. The functionality of this driver is to check the panel status periodicaly and send event to HAL if panel has gone bad.

| | | | | | | | | | | | | | | | | | | | | | Currently there is no error handling done for DSI DCS command APIs like mdss_dsi_cmdlist_put. So for ESD thread use cases, the caller functions of these DCS command APIs do not have error propagated if the panel read/write commands fail. Hence add support for error handling for these functions. Change-Id: I0e558fd32fbfd8ae247b60c92fa2756159c3d3c6 Signed-off-by: Padmanabhan Komanduru <pkomandu@codeaurora.org>

* | msm: mdss: Fix clk warnings for esc clk with dual-dsi panelsUjwal Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | In current implementation if dual-dsi panel's continuous splash screen feature is enabled then feature flag is disabled only for master and not for secondary panel. This leads to clk prepare without clk set rate. For esc clk this leads to clk warning back-trace in the logs. For other clocks, if clk rate changes between suspend/resume then it will lead to rate incorrect programming and unknown behaviour. Fix this by disabling secondary panel's feature flag.

* | mdp3: Add battery FET regulator usageTerence Hampson2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | During idle power-collapse using smart-panel, when PMIC chip goes to sleep, it puts battery FET (batfet) to low power mode (LPM) which allows less than 100mA current to be drawn. Since smart-panel is in self-refresh mode, it can still draw more than 100mA current causing PMIC and MSM reset. To fix this issue, batfet has to be kept in high power mode (HPM). In order to keep batfet in HPM, display driver enables batfet regulator whenever display panel is on.
