FROMLIST: drm: bridge: analogix/dp: Fix the possible dead lock in bridge disable time

It may caused a dead lock if we flush the hpd work in bridge disable time.

The normal flow would like:
  IN --> DRM IOCTL
        1. Acquire crtc_ww_class_mutex (DRM IOCTL)
  IN --> analogix_dp_bridge
        2. Acquire hpd work lock (Flush hpd work)
        3. HPD work already in idle, no need to run the work function.
  OUT <-- analogix_dp_bridge
  OUT <-- DRM IOCTL

The dead lock flow would like:
  IN --> DRM IOCTL
        1. Acquire crtc_ww_class_mutex (DRM IOCTL)
  IN --> analogix_dp_bridge
        2. Acquire hpd work lock (Flush hpd work)
  IN --> analogix_dp_hotplug
  IN --> drm_helper_hpd_irq_event
        3. Acquire mode_config lock (This lock already have been acquired in previous step 1)
** Dead Lock Now **

It's wrong to flush the hpd work in bridge->disable time, I guess the
original code just want to ensure the delay work must be finish before
encoder disabled.

The flush work in bridge disable time is try to ensure the HPD event
won't be missed before display card disabled, actually we can take a
fast respond way(interrupt thread) to update DRM HPD event to fix the
delay update and possible dead lock.

UPSTREAM: drm/exynos: dp: Fix panel and bridge lookup logic

Commit a9fa852886fd ("drm/exynos: dp: add of_graph dt binding support
for panel") made the Exynos DP DT binding more consistent since the OF
graph could be used to lookup either a panel or a bridge device node.

Before that commit, a panel would be looked up using a phandle and a
bridge using the OF graph which made the DT binding not consistent.

But the patch broke the later case since not finding a panel dev node
would cause the driver's to do a probe deferral instead of attempting
to lookup a bridge device node associated with the remote endpoint.

So instead of returning a -EPROBE_DEFER if a panel is not found, check
if there's a bridge and only do a probe deferral if both aren't found.

UPSTREAM: iommu/rockchip: Reconstruct to support multi slaves

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.

FROMLIST: iommu: dma-iommu: use common implementation also on ARM architecture

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

i2c: rk3x: add i2c support for rk3399 soc

- 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)

  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.

UPSTREAM: drm/rockchip: fix wrong pitch/size using on gem

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.

UPSTREAM: drm/rockchip: don't wait for vblank if fb hasn't changed

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.

UPSTREAM: drm/rockchip: vop: fix mask when updating interrupts

Commit dbb3d94 (drm/rockchip: vop: move interrupt registers into
vop_data) introduced new macros for updating the interrupt control
registers but these always use the mask from the register definition
without refining it for the particular bits that are being changed.

This means that whenever we enable/disable a particular interrupt we end
up disabling all of the others as a side effect.

Since the mipi dsi driver need to use the clock of vop to make the
calculation of Blanking. But sometimes the clock driver can not set a
accurate clock_rate for vop, get it by clk_round_rate before mode_set,
so we can get the true value.
