drm/msm: basic KMS driver for snapdragon The snapdragon chips have multiple different display controllers, depending on which chip variant/version. (As far as I can tell, current devices have either MDP3 or MDP4, and upcoming devices have MDSS.) And then external to the display controller are HDMI, DSI, etc. blocks which may be shared across devices which have different display controller blocks. To more easily add support for different display controller blocks, the display controller specific bits are split out into a "kms" module, which provides the kms plane/crtc/encoder objects. The external HDMI, DSI, etc. blocks are part encoder, and part connector currently. But I think I will pull in the drm_bridge patches from chromeos tree, and split them into a bridge+connector, with the registers that need to be set in modeset handled by the bridge. This would remove the 'msm_connector' base class. But some things need to be double checked to make sure I could get the correct ON/OFF sequencing.. This patch adds support for mdp4 crtc (including hw cursor), dtv encoder (part of MDP4 block), and hdmi. Signed-off-by: Rob Clark <robdclark@gmail.com>

drm/msm: drop ARCH_MSM Kconfig depend The ARCH_MSM depend is redundant with ARCH_MSM8960, so we can remove it. Additionally, we are splitting Qualcomm MSM support into legacy (ARCH_MSM) and multiplatform (ARCH_QCOM). The MSM8960 with be ARCH_QCOM going forward so dropping ARCH_MSM will work properly for the new ARCH_QCOM multiplatform build.

DRM/KMS driver for MSM/snapdragon.
config DRM_MSM_FBDEV
bool "Enable legacy fbdev support for MSM modesetting driver"
depends on DRM_MSM
drm: Add separate Kconfig option for fbdev helpers For drivers which might want to disable fbdev legacy support. Select the new option in all drivers for now, so this shouldn't result in any change. Drivers need some work anyway to make fbdev support optional (if they have it implemented, that is), so the recommended way to expose this is by adding per-driver options. At least as long as most drivers don't support disabling the fbdev support. v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm driver can already take advantage of this, which allows us to build msm without any fbdev depencies in the kernel! v3: Move the MODULE_* stuff from the fbdev helper file to drm_crtc_helper.c.

Choose this option if you have a need for the legacy fbdev
support. Note that this support also provide the linux console
support on top of the MSM modesetting driver.

help
Compile in support for logging register reads/writes in a format
that can be parsed by envytools demsm tool. If enabled, register
logging can be switched on via msm.reglog=y module param.
