drm/msm: Remove local fbdev emulation Kconfig option

2015-10-22T19:46:36Z

DRM_MSM_FBDEV config is used to enable/disable fbdev emulation for the msm kms driver. Replace this with the top level DRM_FBDEV_EMULATION config option where applicable. This also prevents build breaks caused by undefined drm_fb_helper_* functions when legacy fbdev support was disabled. Signed-off-by: Archit Taneja Signed-off-by: Rob Clark

drm/msm/mdp5: Basic support for MDP5 v1.7 (MSM8996)

2015-10-22T19:39:57Z

This change adds the basic MDP5 support for MSM8996. Signed-off-by: Stephane Viau Signed-off-by: Rob Clark

drm/msm/mdp: Add Software Pixel Extension support

2015-10-22T19:39:56Z

In order to produce an image, the scalar needs to be fed extra pixels. These top/bottom/left/right values depend on a various of factors, including resolution, scaling type, phase step and initial phase. Pixel Extension are programmed by hardware in most targets - and can be overwritten by software. For some targets (e.g.: msm8996), software *must* program those registers. In order to ease this computation, let's always use bilinear filters, which are easier to program from kernel. Eventually, all of these values will come down from user space for better quality.

drm/msm/mdp5: Use the newly introduced enum mdp_component_type

2015-10-22T19:39:56Z

When calculating phase steps, let's use the same enum mdp_component_type in order to ease the readability; 0/1 indexes are a bit confusing and we now have explicit values to index this type of arrays. Signed-off-by: Stephane Viau Signed-off-by: Rob Clark

drm/msm/hdmi: Add basic HDMI support for msm8996

2015-10-22T19:39:55Z

The HDMI controller is new in MDP5 v1.7. As of now, this change doesn't reflect the novelty and only adds the basics so the probe gets triggered. Signed-off-by: Stephane Viau Signed-off-by: Rob Clark

drm/msm/mdp5: Avoid printing error messages for optional clocks

2015-10-22T19:39:55Z

The current behavior is to try to get optional clocks and print a dev_err message in case of failure. This looks rather confusing and may increase with the amount of optional clocks. We may need a cleaner way to handle per-device clocks but in the meantime, let's reduce the amount of dev_err messages during the probe. Signed-off-by: Stephane Viau Signed-off-by: Rob Clark

drm/msm: Fix IOMMU clean up path in case msm_iommu_new() fails

2015-10-22T19:39:54Z

msm_iommu_new() can fail and this change makes sure that we detect the failure and free the allocated domain before going any further. Signed-off-by: Stephane Viau Signed-off-by: Rob Clark

drm/msm/mdp5: remove the cfg pointer from SMP struct

2015-10-22T19:39:54Z

We want to make sure we control all the information being passed down to SMP block. Having access to the cfg pointer here may create bad things in the future. Signed-off-by: Stephane Viau Signed-off-by: Rob Clark

drm/msm/dsi: Updata LNn_CFG4 register settings for 28nm PHY

2015-10-22T19:39:54Z

The current settings for 28nm PHY data lane CFG4 registers do not work with certain panels. This change is to modify them to hw recommended values. Signed-off-by: Hai Li Signed-off-by: Rob Clark

drm: msm: dsi: Don't attempt changing voltage of switches

2015-10-22T19:39:53Z

In some configurations the supplies are voltage switches and not LDOs, making the set voltage call to fail. Check with the regulator framework if the supply can change voltage before attempting. Signed-off-by: Bjorn Andersson Reviewed-by: Archit Taneja Signed-off-by: Rob Clark
