[RFC PATCH 1/1] drm/exynos: Move platform drivers registration to module init

[Ajay kumar]

Hi,

I have rebased my bridge series on top of linux-next.

This is my git log:
4b38a6f Revert "Revert "ARM: exynos_defconfig: Enable options for
display panel support""
6fb39a7 ARM: dts: peach-pit: represent the connection between bridge
and panel using videoport and endpoints
aee649c ARM: dts: snow: represent the connection between bridge and
panel using videoport and endpoints
5b76d8d drm/bridge: Add i2c based driver for ps8622/ps8625 bridge
581257f Documentation: bridge: Add documentation for ps8622 DT properties
178e8b9 Documentation: devicetree: Add vendor prefix for parade
0ceea75 Documentation: drm: bridge: move to video/bridge
f143e2e drm/bridge: ptn3460: use gpiod interface
2d5cb9d drm/bridge: ptn3460: probe connector at the end of bridge attach
32ac563 drm/bridge: ptn3460: support drm_panel
91c6c30 drm/exynos: dp: support drm_bridge
7eea7eb drm/bridge: ptn3460: Convert to i2c driver model
602f343 drm/bridge: make bridge registration independent of drm flow
14c7143 drm/bridge: do not pass drm_bridge_funcs to drm_bridge_init
2c01ac4 drm/bridge: ptn3460: Few trivial cleanups
7415f6c arm: dts: Exynos5: Use pmu_system_controller phandle for dp phy
28655d1 drm/exynos: Move platform drivers registration to module init
ed6778a Add linux-next specific files for 20141121

I have attached the rebased patches as well.
I tested it on snow, peach_pit and peach_pi without *clk_ignore_unused*.
Display is totally fine with exynos_defconfig (booting is fine even
with CONFIG_SND_SOC_SNOW=y)

Regards,
Ajay Kumar
