drm/exynos: fix incorrect cpu address for dma_mmap_attrs()

2016-02-15T14:25:23+00:00

dma_mmap_attrs() should be called with cpu address returned by
dma_alloc_attrs(). Existing code however passed pages array base as cpu
address. This worked only by a pure luck on ARM architecture. This patch
fixes this issue.

drm/exynos: exynos5433_decon: fix wrong state in decon_vblank_enable

2016-02-15T14:25:22+00:00

BIT_IRQS_ENABLED was never set because of incorrect test in
decon_vlank_enable() function, what resulted in lack of enabling vblank
support. This patch fixes this issue.

drm/exynos: exynos5433_decon: fix wrong state assignment in decon_enable

2016-02-15T14:25:22+00:00

Patch ebf3fd403b79ba6561bd1a4bb5a7cacc99da08e5 ("drm/exynos: add
pm_runtime to DECON 5433") removed some code from decon_enable()
function, but it left set_bit(BIT_SUSPENDED, &ctx->flags) call, which
was earlier called only in error path. This patch removes it, what
finally lets driver to go out of suspended state.

drm/exynos: dsi: restore support for drm bridge

2016-02-15T14:25:21+00:00

This patch fixes issue introduced by commit
cf67cc9a29ac19c98bc4fa0e6d14b0c1f592d322 ("drm/exynos: remove struct
exynos_drm_display"), which removed assigning of drm bridge to drm
encoder. Lack of it caused that no bridge callbacks were called on
encoder enable/disable actions.

drm/exynos: mic: make all functions static

2016-02-15T14:25:20+00:00

There is no point exposing all internal functions to global kernel name
space, so make all internals functions static.

drm/exynos: mic: convert to component framework

2016-02-15T14:25:19+00:00

MIC is SoC component and important part of kms pipeline on Exynos5433,
so convert it to use component framework like other KMS/CRTC drivers.
MIC driver is already listed on KMS component driver list in Exynos DRM
core, so without this conversion, initialization of Exynos DRM core
fails on Exynos 5433 SoC.

drm/exynos: ipp: fix incorrect format specifiers in debug messages

2016-02-15T14:25:17+00:00

Drivers should use %p for printing pointers instead of hardcoding them
as hexadecimal integers. This patch fixes compilation warnings on 64bit
architectures.
