* | msm: mdss: fix fb device pm suspend and resume handlersAravind Venkateswaran2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Under normal circumstances, the framebuffer device should have been blanked or configured to a low power mode prior to the pm suspend callback getting executed. In cases when this sequence is not followed, blank the framebuffer as part of pm suspend handler to ensure that all display resources are freed. Similarly, if the framebuffer was explicitly blanked during suspend, then unblank it when resuming. This also eliminates the need for the existing sysfs node to indicate always-on display mode.

* | msm: mdss: reduce waiting time before turn off mdp clockKuogee Hsieh2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | Vsync happens at every 16.6 ms. Currently it waits for 6 vsyncs (100 ms) time before turning off mdp clock if there is no new frame update. During suspend procedure, change it to 1 so that mdp clock is turned off 1 vsync after kickoff has completed if there is kickoff pending. Otherwise mdp clock is turned off at next vsync.

* | mdss: mdp: secure buffer is unmaped without iommu attachedSiva Yarravarapu2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | For secure content/buffers, it is a requirement that IOMMU is attached before un-mapping can be called, otherwise the scm call to unmap the buffer will not be successful. In the current implementation it is possible to unmap buffer while going into suspend without IOMMU being attached which leads to secure playback failures in subsequent sessions. Fix this by ensuring IOMMU is attached before buffer is freed/unmapped.

| | | | | | | | | | | | | | | | | | compat layer ovarlay structure needs to be updated whenever there is change in 64 bit overlay structure. This change updates the compat layer. Change-Id: Ibeaef3d825d8c33ee8c6abf9caaae8432b6b0645 Signed-off-by: Jeevan Shriram <jshriram@codeaurora.org>
* | msm: mdss: Align the shared memory length to PAGE_SIZEJeevan Shriram2016-03-23
| | | | | | | | | | | | | | | | | | It is possible that userspace modifies the frame buffer parameters. In such cases ensure to align the frame buffer size to avoid mmap failures. Change-Id: I4a002694c26c8fface45d8e274d79d5624cc8158 Signed-off-by: Jeevan Shriram <jshriram@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | Framebuffer commpression(FBC) 2.0 has new bit fields added to the registers. Configure FBC registers correctly based on the dtsi configuration. FBC 2.0 has increased the compression ratio to 1/3 and has configurable block size(in lines).

| | | | | | | | | | | | | | | | | | | | When entering doze mode, do not turn off the interface clocks since display updates are expected in this mode. This also avoid unnecessary delays when entering doze mode while trying to wait for the clocks to be turned off.
