This patch adds of_graph dt binding support for panel device
and also keeps the backward compatibility.
i.e.,
The dts file for Exynos5800 based peach pi board
has a panel property so we need to keep the backward compatibility.
Changelog v3:
- bind only one of two nodes outbound - panel or bridge.
Changelog v2:
- return -EINVAL if getting a port node failed.

Let pm_runtime handle the enabling/disabling of the device with
proper refcnt instead of rely on specific flags to track the enabled
state.
Chnagelog v3:
- revive dpms_mode to keep current dpms mode.

Add a helper that can be used to obtain the number of bits per pixel
corresponding to a given MIPI DSI pixel format. This is useful in
bandwidth calculations, for example.

There are some IPs, such as video encoder/decoder, contains 2 slave iommus,
one for reading and the other for writing. They share the same irq and
clock with master.
This patch reconstructs to support this case by making them share the same
Page Directory, Page Tables and even the register operations.
That means every instruction to the reading MMU registers would be
duplicated to the writing MMU and vice versa.

This patch replaces ARM-specific IOMMU-based DMA-mapping implementation
with generic IOMMU DMA-mapping code shared with ARM64 architecture. The
side-effect of this change is a switch from bitmap-based IO address space
management to tree-based code. There should be no functional changes
for drivers, which rely on initialization from generic arch_setup_dna_ops()
interface. Code, which used old arm_iommu_* functions must be updated to
new interface.
To avoid build failed on ARCH arm,we mannually fix the following two files that
to use arch_set_dma_ops API
arch/arm/mach-highbank/highbank.c
arch/arm/mach-mvebu/coherency.c

- new method to caculate i2c timings for rk3399:
There was an timing issue about "repeated start" time at the I2C
controller of version0, controller appears to drop SDA at .875x (7/8)
programmed clk high. On version 1 of the controller, the rule(.875x)
isn't enough to meet tSU;STA
requirements on 100k's Standard-mode. To resolve this issue,
sda_update_config, start_setup_config and stop_setup_config for I2C
timing information are added, new rules are designed to calculate
the timing information at new v1.
- pclk and function clk are separated at rk3399.
- support i2c highspeed mode: 1.7MHz for rk3399

export the framebuffer_changed() helper so it can be reused.
