In some situaitons, we will want a clock rate be kept while its parent

From: Icenowy Zheng
Notify TCON0 clock (and in consequence PLL-MIPI by CLK_SET_RATE_PARENT)
to reset when PLL-Video0 changes (because of HDMI PHY clk which is a
child of PLL-Video0 and has CLK_SET_RATE_PARENT set). In this way we can
get clock tree to satisfy both pipelines.

From: Icenowy Zheng
As the A64 CCU driver has already the ability to keep TCON0 clock stable
when HDMI changes its parent's clock, do not protect TCON0 clock on A64
in the TCON driver to allow PLL-Video0 gets changed by HDMI (the CCU
will then restore the TCON0 clock rate).

The following functions are only used inside the mm subsystem, so it's
better to move their declarations to the mm/internal.h file.
1. shrinker_debugfs_add()
2. shrinker_debugfs_detach()
3. shrinker_debugfs_remove()

The debugfs_remove_recursive() will wait for debugfs_file_put() to return,
so the shrinker will not be freed when doing debugfs operations (such as
shrinker_debugfs_count_show() and shrinker_debugfs_scan_write()), so there
is no need to hold shrinker_rwsem during debugfs operations.

Currently, the shrinker instances can be divided into the following three
types:
a) global shrinker instance statically defined in the kernel, such as
workingset_shadow_shrinker.
b) global shrinker instance statically defined in the kernel modules, such
as mmu_shrinker in x86.
c) shrinker

Currently, the synchronize_shrinkers() is only used by TTM pool. It only
requires that no shrinkers run in parallel.
After we use RCU+refcount method to implement the lockless slab shrink,
we can not use shrinker_rwsem or synchronize_rcu() to guarantee that all
shrinker invocations have seen an up
Currently, we maintain two linear arrays per node per memcg, which are
shrinker_info::map and shrinker_info::nr_deferred. And we need to resize
them when the shrinker_nr_max is exceeded, that is, allocate a new array,
and then copy the old array to the new array, and finally free the old
array by R
The shrinker_rwsem is a global read-write lock in shrinkers subsystem,
which protects most operations such as slab shrink, registration and
unregistration of shrinkers, etc. This can easily cause problems in the
following cases.
1) When the memory pressure is high and there are many filesystems
Like global slab shrink, this commit also uses refcount+RCU method to make
memcg slab shrink lockless.
Use the following script to do slab shrink stress test:
```
DIR="/root/shrinker/memcg/mnt"
do_create()
{
mkdir -p /sys/fs/cgroup/memory/test
echo 4G > /sys/fs/cgroup/memory/test/memory
For now, reparent_shrinker_deferred() is the only holder of read lock of
shrinker_rwsem. And it already holds the global cgroup_mutex, so it will
not be called in parallel.
Therefore, in order to convert shrinker_rwsem to shrinker_mutex later,
here we change to hold the write lock of shrinker_rwse
Now there are no readers of shrinker_rwsem, so we can simply replace it
with mutex lock.

Of hand looks good to me,
Samsung DSIM used in older Exynos SoCs (like Exynos 4210, 4x12, 3250)
doesn't report empty level of packer header FIFO. In case of those SoCs,
use the old way of waiting for empty command tranfsfer FIFO, removed
recently by commit 14806c641582 ("Drain command transfer FIFO before
transfer").
Fixes
PCI core API pci_dev_id() can be used to get the BDF number for a pci
device. We don't need to compose it mannually. Use pci_dev_id() to
simplify the code a little bit.

Hello,
These patches add support for the JDI LPM102A188A display panel,
found in the Google Pixel C.
Patch 1 adds the DT bindings for the panel.
Patch 2 adds the panel driver, which is based on the downstream
kernel driver published by Google and developed by Sean Paul.
Patches 3-5 add DT nodes
The JDI LPM102A188A is a 2560x1800 IPS panel found in the Google Pixel C.
This driver is based on the downstream GPLv2 driver released by Google
written by Sean Paul [1], which was then adapted to the newer kernel APIs.

There was some debate on IRC about software color conversion in DRM
drivers. I was not part of it, but one of my optimization for mgag200
might be affected. So I think it's better to document it clearly, so
that it's easier to know what is allowed or not.
I hope it reflects the actual consensus, an
After discussions on IRC, the consensus is that the DRM drivers should
not do software color conversion, and only advertise the supported formats.
Update the doc accordingly so that the rule and exceptions are clear for
everyone.

The encode_dma() function has some validation on in_trans->size but it's
not complete and it would be more clear to move those checks to
find_and_map_user_pages().
The encode_dma() had two checks:
if (in_trans->addr + in_trans->size < in_trans->addr || !in_trans->size)

This patch adds support for the bridge/connector attached to the
HDMI output, allowing to model the hardware properly. It keeps
backwards compatibility with existing bindings and is required
by devices which have a simple or MHL bridge connected to HDMI
output like ASUS P1801-T or LG P880/P895 or H
All ASUS Transformers have micro-HDMI connector directly available.
After Tegra HDMI got bridge/connector support, we should use connector
framework for proper HW description.

Some Tegra device-trees may specify a video output graph, which involves
MHL bridge/simple bridge and/or connector framework. This patch adds
support for the bridge/connector attached to the HDMI output, allowing
us to model the hardware properly.
