Jean Delvare b26c04f47c drm/exynos: Fix PTN3460 dependency
The following configuration options combination:

CONFIG_DRM_EXYNOS_DP=y
CONFIG_DRM_PTN3460=m

currently leads to the following linker failure:

drivers/built-in.o: In function `exynos_drm_attach_lcd_bridge':
.../drivers/gpu/drm/exynos/exynos_dp_core.c:1004:
undefined reference to `ptn3460_init'

This is because ptn3460_init can't be implemented in a module while
its caller is built into the kernel. So add the proper dependency in
Kconfig so that the above can't happen.

I moved DRM_PTN3460 earlier in Kconfig, next to the I2C helper module
section, so that the user has a chance to select it before moving to
the Exynos-specific section.

IMHO the proper way to solve the problem would be to turn ptn3460 into
a clean I2C driver, similar to the other I2C helper chip drivers. It's
the only way to not sink into impossible-to-guess dependencies. Then
ptn3460 could even be moved together with the other I2C helper chip
drivers.

Rahul Sharma 66367461e5 drm/exynos: use 4WORD dma burst length for small fbs
In case of exynos, setting dma-burst to 16Word causes permanent
tearing for very small buffers, e.g. cursor buffer. Burst Mode
switching, which is based on overlay size is not recommended as
overlay size varies a lot towards the end of the screen. This
causes unstable DMA which results into tearing again.

Rendering small buffers with lower burst size doesn't
cause any noticable performance overhead. 128 pixel width is
selected based on mulitple experiments with exynos5 SoCs.

Rahul Sharma 049d34e94f drm/exynos: use regmap interface to set hdmiphy control bit in pmu
Exynos drm hdmi driver used to get dummy hdmiphy clock to
control the PMU bit for hdmiphy. This bit needs to be set
before setting any resolution to hdmi hardware. This was
handled using dummy hdmiphy clock which is removed here.

PMU is already defined as system controller for exynos
SoCs. Hdmi driver is modified to control the phy enable bit
inside PMU using regmap interfaces.

Devicetree binding document for hdmi is also updated.

Therefore, it is not necessary to set fix->smem_{start,len} or

Sagar Kamble 6c6a3996f2 Documentation: drm: describing drm properties exposed by various drivers
Started documenting drm properties for drm drivers. This patch provides
information about properties in drm, i915, psb and cdv/gma-500. Information
about other properties can be added on top of these.

v2: Added description of drm properties in armada, exynos, i2c/ch7006, noveau,
omap, qxl, radeon, rcar-du

v3: Removed "Property Object" column since it is implementation related. Property
type column refined.[Ville's review comments]

v4: Removed whitespace warnings and minor nits. [Randy's review comments]

v5: Restructured output for ENUM properties

v6: Review comments on formatting the table. [Laurent's review comments]
