The patch adds parallel output interface to FIMD device driver.
It also restores support for panels initialized by boot loader,
but without proper kernel driver.
Driver uses video interface bindings to find connected panel.
It uses drm_panel interface to interact with the panel.

This patch removes all of the suspend/resume logic from the individual
drivers and consolidates it in drm_drv. This consolidation reduces the
number of functions which enable/disable the hardware to just one -- the
dpms callback. This ensures that we always power up/down in a consistent
manner.

This patch separates the fimd_activate function into poweron/poweroff
functions to be more consistent with the other drivers in exynos drm. It
also properly cleans up after failures in poweron. The functions have
also been shuffled around such that they are all in the same
spot in the file and poweron/poweroff can be called from the dpms function.

This patch splits display and manager from subdrv. The result is that
crtc functions can directly call into manager callbacks and encoder
functions can directly call into display callbacks. This will allow
us to remove the exynos_drm_hdmi shim and support mixer/hdmi & fimd/dp
with common code.

This patch renames the display_op power_on to dpms to accurately reflect
what the function does.
The side-effect of this patch is that the new hdmi dpms callback is now
invoked twice in the dpms path. This is safe and will be dealt with when
the exynos_drm shim goes away.

This patch changes the manager ops callbacks from accepting the subdrv

This patch fixes wrong pixel format setting.
A pixel format is decided according to bpp and depth, or user-requested
format but fimd driver considered only bpp value to decide a proper pixel
format. So this patch makes a proper pixel format to be set according
to drm_framebuffer's pixel_format which is set by addfb with bpp and
depth, or addfb2 with user-requested format.

While migrating to common clock framework (CCF), I found that the FIMD clocks
were pulled down by the CCF.
If CCF finds any clock(s) which has NOT been claimed by any of the
drivers, then such clock(s) are PULLed low by CCF.
Calling clk_prepare() for FIMD clocks fixes the issue.
This patch also replaces clk_disable() with clk_unprepare() during exit, since
clk_prepare() is called in fimd_probe().

Replaces the "platform_get_resource() for IORESOURCE_IRQ" with
platform_get_resource_byname().
Both in exynos4 and exynos5, FIMD IP has 3 interrupts in the order: "fifo",
"vsync", and "lcd_sys".
But The FIMD driver expects the "vsync" interrupt to be mentioned as the
1st parameter in the FIMD DT node. So to meet this expectation of the
driver, the FIMD DT node was forced to be made by keeping "vsync" as the
1st paramter.
For example in exynos4, the FIMD DT node has interrupt numbers
mentioned as <11, 1> <11, 0> <11, 2> keeping "vsync" as the 1st paramter.
This patch fixes the above mentioned "hack" of re-ordering of the
FIMD interrupt numbers by getting interrupt resource of FIMD by using
platform_get_resource_byname().

If fimd is runtime suspended (by DPMS OFF), fimd_suspend does not
call fimd_activate(false) and just returns. Similarily the check in
fimd_resume should not resume if previously runtime_suspended.
Instead the existing check does the opposite. So if fimd was not
runtime suspended, suspend will turn off fimd but resume will not turn
it on. This patch fixes this issue by reversing the condition.
