This reverts commit d089621896 was
original to prevent multiple MODULE_DEVICE_TABLE in one module.
Which, as a side-effect broke autoloading of the module.
Since 21bdd17b21 it is possible to have
multiple calls to MODULE_DEVICE_TABLE, so the patch can be
reverted to restore support for autoloading

The offset of register DSIM_PLLTMR_REG in Exynos5410 / 5420 / 5440
SoCs is different from the one in Exynos4 SoCs.
In case of Exynos5410 / 5420 / 5440 SoCs, there is no frequency
band bit in DSIM_PLLCTRL_REG, and it uses DSIM_PHYCTRL_REG and
DSIM_PHYTIMING*_REG instead.
So this patch adds driver data to distinguish it.

This is a temporary solution and should be made by more
generic way.
To support LCD I80 interface, the DSI host should register
TE interrupt handler from the TE GPIO of attached panel.
So the panel generates a tearing effect synchronization signal
then the DSI host calls the CRTC device manager to trigger
to transfer video image.

This configuration could be used in MIPI DSI command mode also.
And adds user manual description for display configuration.

This patch makes sure that exynos drm framework handles deferred
probe case correctly.
Sub drivers could be probed before resources, clock, regulator,
phy or panel, are ready for them so we should make sure that exynos
drm core waits until all resources are ready and sub drivers are
probed correctly.
Chagelog v2:
- Make sure that exynos drm core tries to bind sub drivers only in case that
they have a pair: crtc and encoder/connector components should be a pair.
- Remove unnecessary patch:
drm/exynos: mipi-dsi: consider panel driver-deferred probe
- Return error type correctly.

Exynos drm driver is a single driver so pm operation
for kms drivers should be done by connector->dpms
at top level driver.
If kms driver has its own pm interfaces, single driver model
would be broken so this patch removes unnecessary pm interfaces
from dsi driver.

This patch adds component framework support to resolve
the probe order issue.
Until now, exynos drm had used codes specific to exynos drm
to resolve that issue so with this patch, the specific codes
are removed.

The patch adds driver for Exynos DSI master (DSIM). It is a platform driver
which is registered as exynos_drm_display sub-driver of exynos_drm framework
and implements DRM encoder/connector pair.
It is also MIPI-DSI host driver and provides DSI bus for panels.
It interacts with its panel(s) using drm_panel framework.
