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.

(cherry picked from commit ec26d9e938)
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.

(cherry picked from commit cd6438c5f8)
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

This patch moves all the IOMMU-based DMA-mapping code from arch/arm64/mm

- 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

The Rockchip driver cannot use drm_atomic_helper_wait_for_vblanks()
because it has hardware counters for neither vblanks nor scanlines.
In order to simplify re-implementing the functionality for this driver,
export the framebuffer_changed() helper so it can be reused.

(cherry picked from commit f0442df215)
args->pitch and args->size may not be set by userspace, sometimes
userspace only malloc args and not memset args to zero, then
args->pitch and args->size is random, it is very danger to use
pitch/size on gem.
pitch's type is u32, and min_pitch's type is int, example,
pitch is 0xffffffff, then pitch < min_pitch return true, then gem will
alloc very very big bufffer, it would eat all the memory and cause kernel
crash.
Stop using pitch/size from args, calc them from other args.

(cherry picked from commit e3c4abdb3b)
As commented in drm_atomic_helper_wait_for_vblanks(), userspace relies
on cursor ioctls being unsynced. Converting the rockchip driver to
atomic has significantly impacted cursor performance by making every
cursor update wait for vblank.
By skipping the vblank sync when the framebuffer has not changed (as is
done in drm_atomic_helper_wait_for_vblanks()) we can avoid this for the
common case of moving the cursor and only need to delay the cursor ioctl
when the cursor icon changes.
We cannot add the check on legacy_cursor_update since that results in
the cursor bo being unreferenced while the hardware may still be reading
it. Fully supporting unsynced cursor updates is left for the future
when the atomic helper framework supports async updates.
