In MDP5, CTL contains information of the whole pipeline whose output goes down to a display interface. In various cases, one interface may require 2 CRTCs, but only one CTL. Some interfaces also require to use certain CTLs. Instead of allocating CTL for each active CRTC, this change is to associate a CTL with each interface. Signed-off-by:

This change is to add properties alpha/zpos/blend_mode to mdp5 plane for alpha blending operation to generate the blended output. v1: Initial change v2: Change "premultilied" property to enum (Rob's comment) Signed-off-by:

This was a hold-over from the pre-atomic days and legacy userspace that only understood CRTCs. Fortunately we don't have any properties, so this doesn't change anything. But before we start growing some plane properties, we should fix this. Signed-off-by: -

DSI PHY errors are falsely reported whenever a dsi error occurs. This is because DSI_DLN0_PHY_ERR isn't only used as a status register, but also used to mask PHY errors. Currently, we end up reading the mask bits too and therefore always report errors. Ignore the register mask bits and check for only the status/clear bits. Signed-off-by:

The maximum output width of one pipeline depends on the LayerMixer's capability. It may be different on each target. Also, MDP5 doesn't have vertical limitation in one frame, as long as the pixel clock can be supported. This change obtains the maximum LM resolution from configuration table and treat it as the whole pipe's limitation for MDP5. The size limit on MDP4 is not changed. Signed-off-by: -

This change adds the MDP and HDMI support for msm8x94. Note that HDMI PHY registers are not being accessed anymore from the driver. Signed-off-by:
Stephane Viau <sviau@codeaurora.org> [rename compatible s/8x94/8994/ since preference is to not trust the marketing folks who invent chip #'s but instead name things after the lead chip.. we should rename some 80XY to 89XY to standardize on the lead chip but leave that for another patch. Also, update dt bindings doc] Signed-off-by:

->reset() currently only accesses HDMI core registers, and yet it is located in hdmi_phy*. Since no PHY registers are being accessed during ->reset(), it would be better to bring that function in hdmi core module where HDMI core registers are usually being accessed. This will also help for msm8x94 for which no PHY registers accesses are done (->phy_init == NULL) but the HDMI PHY reset from HDMI core still needs to be done. Note: SW_RESET_PLL bit is not written in hdmi_phy_8x60_reset(); this write should not affect anything if the corresponding field is not writable. Signed-off-by:

The current term of *dual panel* in DSI driver code causes confusion. It is supposed to indicate the panel using two DSI links. Rename it to *dual DSI*. Signed-off-by:

Hai Li authored
The source PLL to be used by each DSI PHY should be decided by DSI manager based on dual DSI information, while the register programming to select PLL is different from one type of PHY to another. This change adds the H/W difference to PHY configuration and updates the interface between DSI manager and PHY. With this change, PLL selection can be supported on different targets. Signed-off-by:

Release all blocks after the pipe is disabled, even when vsync didn't happen in some error cases. Allow requesting SMB multiple times before configuring to hardware, by releasing blocks not programmed to hardware yet for shrinking case. This fixes a potential leak of shared memory pool blocks.

Merge tag 'drm-amdkfd-next-fixes-2015-08-05' of git://people.freedesktop.org/~gabbayo/linux into drm-next Two small bug fixes for the code you pulled for 4.3: - Used a SHIFT define instead of a MASK define to check if a bit is turned on when destroying hqd. Luckily, this is in gfx7 interface file with amdgpu, which was used only for bring-up purposes of amdgpu, so no real effect on a running system - Used a logical AND instead of a bitwise AND operator, when initializing sdma virtual memory when using SDMA queues * tag 'drm-amdkfd-next-fixes-2015-08-05' of git://people.freedesktop.org/~gabbayo/linux: drm/amdkfd: fix bug when initializing sdma vm drm/amdgpu: fix bug when amdkfd destroys hqd

Merge branch 'drm-sti-next-atomic-2015-08-11' of http://git.linaro.org/people/benjamin.gaignard/kernel into drm-next This serie of patches fix minor bugs around how driver sub-components are bind and planes z-ordering. The main part is about atomic support: using more atomic helpers allow us to simplify the code (~300 lines removed) and to ahve a better match between drm concepts (planes and crtc) and hardware split.

Thierry Reding authored
The drm_send_vblank_event() function treats negative CRTC indices as meaning that a driver doesn't have proper VBLANK handling. This is the only place where DRM needs negative CRTC indices, so in order to enable subsequent cleanup, remove this special case and replace it by the more obvious check for whether or not VBLANK support was initialized.

Some setups do not register a default VGA device, in which case the VGA arbiter will still complain about the (non-existent) PCI device being a non-VGA device. Fix this by making the error message conditional on a default VGA device having been set up. Note that the easy route of erroring out early isn't going to work because otherwise priv->target won't be properly updated. Signed-off-by:
