* msm: mdss: hdmi: handle CEC interrupts if CEC feature is enabledTatenda Chipeperekwa2016-06-17
| | | | | | | | | | | | Handle CEC interrupts in the CEC hardware module only if the CEC feature is explicitly enabled by the CEC framework. This will prevent the CEC hardware module from unnecessarily processing interrupts that will not be handled by the CEC framework (if the feature is not explicity enabled).

* msm: mdss: enable ref count based PM_QOS request for DSISandeep Panda2016-06-16
| | | | | | | | | | | | | DSI controller requests for PM_QOS while sending DCS commands, so that CPU does not go to idle state until DCS command transfer is finished. But this request can come independently from multiple clients such as different DSI controllers. So this change adds ref count based PM_QOS request to avoid warning for multiple QOS add request and unwanted results, if one client removes the request while the other clients still need it.

* msm: mdss: Update the default PP bindingGopikrishnaiah Anandan2016-06-07
| | | | | | | | | | | | | | If mdss version is not part of get driver ops function currently we set the driver ops to NULL. When driver ops is NULL post processing driver will treat that msm is legacy target and program the post processing registers. For newer target if get driver ops function is not updated pp driver will assume it as legacy msm target and programme the registers incorrectly. Changing the default behaviour to stub function pointers will ensure that above use-case is gracefully handled.

* msm: mdss: fix pipe cleanup for multi-rect pipesIngrid Gallardo2016-06-03
| | | | | | | | | | | | | | | | | | For multi-rect pipes, driver tries to release the pipe only when both pipes for both rectangles are in the destroy list. Current code always detects that there are two pipes with the same number in the list, since the first iteration to look for the pipe in the list always correspond to the same pipe used as the initial index. This causes that driver unnecesary halt the dma pipe when still in use for the second rect that is still not freed. Fix this issue by making sure the same pipe objects are not used to check if there are two pipes with the same index in the release list.

* Revert "msm: mdss: hdmi: check clk state before power on"Tatenda Chipeperekwa2016-06-01
| | | | | | | | | | | | | This reverts commit 05f3cbbe5cc481141434a90e606ff9fc92da5e0d ("msm: mdss: hdmi: check clk state before power on"). The check for clock state was required for earlier target's fast hot plug use cases, and uses the clock framework for check for clock rates. This approach does not work on msmcobalt and causes the power on sequence for HDMI to fail.

* msm: mdss: Export rotator interrupt and share rotator smmuAlan Kwong2016-05-26
| | | | | | | | | | | | | | | | | | | Existing rotator block is serviced by fbdev rotator driver. This change enables usermode to use external v4l2 rotator driver by exporting rotator interrupts (WB0 & WB1) thru interrupt domain, and share smmu access for writeback and rotator. mdp_irq_export is only set if has_separate_rotator is specified in device tree and MDSS version is prior to 2.0. mdp_irq_export is set to zero otherwise, and will effectively disable mdp irq export and will introduce only minimal overhead to interrupt processing. This is the default behaviour for MDSS newer than 2.0. CRs-Fixed: 1017182 Signed-off-by: Alan Kwong <akwong@codeaurora.org> Change-Id: If634894768b02d124ceab071a9eca1c36f258600
