In order to provide low jitter dclk_lcdc for dislay(especially HDMI),
we neeed to set dclk_lcdc's src pll with max VCO. Thus we add
clk_pll_ops_3368_low_jitter type pll to get pll low jitter setting
from a table. Also dclk_lcdc ops in rk3368 is modifided to get best
parent rate from a table firstly, or caculate a parent rate if not
found in the table.

Sometimes we want to display logo at hdmi screen. but hdmi uboot
resolution maybe different with framebuffer size, so we need read
logo config from regs and decide how to display logo at kernel.
now only support uboot logo size = kernel logo size

This patch introduces generic code to perform PM domain look-up using
device tree and automatically bind devices to their PM domains.
Generic device tree bindings are introduced to specify PM domains of
devices in their device tree nodes.
Backwards compatibility with legacy Samsung-specific PM domain bindings
is provided, but for now the new code is not compiled when
CONFIG_ARCH_EXYNOS is selected to avoid collision with legacy code.
This will change as soon as the Exynos PM domain code gets converted to
use the generic framework in further patch.
This patch was originally submitted by Tomasz Figa when he was employed
by Samsung.

The intent of this callback is to simplify detachment of devices from
their PM domains. Further patches will show the benefit.

In some cases, we want to be able to round the divider to the closest one,
instead than rounding up.
This patch adds a new CLK_DIVIDER_ROUND_CLOSEST flag to specify the divider
has to round to closest div, keeping rounding up as de default behaviour.

commit ccf54555da upstream.
The direction field is set on 7 bits, thus we need to AND it with 0111 111 mask
in order to retrieve it, that is 0x7F, not 0xCF as it is now.

commit f144d1496b upstream.
This can be set by quirks/drivers to be used by the architecture code
that assigns the MSI addresses.
We additionally add verification in the core MSI code that the values
assigned by the architecture do satisfy the limitation in order to fail
gracefully if they don't (ie. the arch hasn't been updated to deal with
that quirk yet).

[ Upstream commit 84bc88688e ]
There could be a signed overflow in the following code.
The expression, (32-logmask) is comprised between 0 and 31 included.
It may be equal to 31.
In such a case the left shift will produce a signed integer overflow.
According to the C99 Standard, this is an undefined behavior.
A simple fix is to replace the signed int 1 with the unsigned int 1U.

There are two thread will update the win config,
one is update_regs handler, another is hdmi hotplug
thread, win config maybe modify by another thread
unexpectly, then vop scan umap address, cause iommu
crash, so we need use a mutex to protect win config.

dw_mci write cmd index to CMD register to trigger sending cmd by BIU.
However, if device fall into panic holding cmd/data line to low level cause BIU
cannnot send out cmd forever. So no cmd_done_int will come. AND, cmd response timeout
only valid after cmd been sent. Nothing to break this loop, we need a s/w recovery from
STATE_SENDING_CMD to STATE_IDLE, and the pending one reported as -ETIMEOUT, let caller
decide howto again.

Introduce common framework for client/protocol drivers and
controller drivers of Inter-Processor-Communication (IPC).
Client driver developers should have a look at
include/linux/mailbox_client.h to understand the part of
the API exposed to client drivers.
Similarly controller driver developers should have a look
at include/linux/mailbox_controller.h
