commit bf5ce5bf3cc7136fd7fe5e8999a580bc93a9c8f6 upstream.
Commit 655fe4effe0f ("usbcore: add sysfs support to xHCI usb3
hardware LPM") introduced usb3_hardware_lpm sysfs node. This
doesn't show the correct status of USB3 U1 and U2 LPM status.
This patch fixes this by replacing usb3_hardware_lpm with two
nodes, usb3_hardware_lpm_u1 (for U1) and usb3_hardware_lpm_u2
(for U2), and recording the U1/U2 LPM status in right places.
This patch should be back-ported to kernels as old as 4.3,
that contains Commit 655fe4effe0f ("usbcore: add sysfs support
to xHCI usb3 hardware LPM").

In the current implementation, driver makes a decision to use
pingpong-split data path if HW supports pingpong-split and connected
panel is a dual-DSI. However, in the high tier targets like msm8996 it
is possible to use dual-dsi panels in multiple modes, i.e with single
layer mixer + pingpong-split or dual layer mixer. So the correct place to
define if pingpong-split will be used or not is with panel configuration
not with the MDP driver.
In order to support this, MDP device node will continue using its
property qcom,has-pingpong-split to tell driver that underlying HW
supports pingpong-split. Introduce a new panel property,
qcom,split-mode, which will be used to decide if pingpong-split
for a given panel should be used or not.

In the current implementation, the continuous splash screen flag
is set based on whether there is handoff pending in MDP or not.
With the dual DSI use-case now in place, there is possibility that
the primary panel has continuous splash enabled whereas the other
panel doesn't have the feature enabled. Add change to take care of
this by checking if a particular interface is enabled in MDP_INTF_SEL
register to set the cont. splash screen flag. Remove the DT entries
for continuous splash screen since it is no longer needed after this
change.

For command mode panels current code calculations adjust the mdp
clock rate based on the minimum dsi pixel clock rate. This is
wrong and can lead to power issues since this rate considers
the blanking times which are not required for the mdp clock
calculations.
This change optimize the calculations by only considering the worst
width that could be processed by the mdp without blanking periods
and consider the time expected for the transfer by adjusting
the mdp clock in order to meet the performance requested; this
time can be tuned through the panel configuration.

Based on the board configuration, the two DSI controllers can either
drive two independent panels or drive a single panel in split display
mode. DSI0 PLL can drive split display configuration ands it is not
supported by DSI1 PLL. DSI0 PLL can drive a single DSI panel on either
DSI0 or DSI1 controller whereas DSI1 PLL can drive a DSI panel only on
DSI1 controller. Based on this, it is necessary to configure the
source for the DSI link clocks dynamically. Implement this by adding
support for a new pll source configuration entry.

Current DSI driver implementation treats the two DSI controllers
as separate devices. However, some use cases might require the
two DSI devices to be aware of the global configuration of the
display interfaces. For instance, the panel/board configuration
might require both the DSI controllers to work in tandem and
drive a split DSI panel or else drive two different panels
independently. Add a root DSI node in MDSS dtsi and the two
DSI controller nodes as the child nodes. Refactor the DSI
panel related dtsi files and DSI drivers to support this new
design. The DSI root node contains the global information needed
for the DSI controllers like the DSI h/w configuration needed to
drive the panel(s), the DSI register space ranges etc.

MDSS currently has fixed maximum bandwidth enabled in DT file.
But there are scenarios where this maximum bandwidth support
can change to enhance performance. Based on scenarios such as
camera use, or flip involved declare the max bandwidth for
usecase in DT and change accordingly based on usecase.

During split display case, pll-1 share vco output of pll-0.
Therefore pll-1's related clock dividers need to be
configured along with pll-0.

Implement dsi related clocks framework so that dsi
vco pll related function be called to output correct
vco rate base on byte clock rate. After that pixel
clock rate can be achieved through MND setting.

TZ introduced a recent change which mandates the scm call
before accessing the pll registers. So, when continuous splash
is disabledin bootloader, the scm call is not made and it causes
device crash when the pll driver tries to access the registers.
This change makes it return with a disabled handoff clk from the
pll driver when continuous splash is disabled, thus not accessing
the pll registers at this point.

Each display output interface such as eDP, HDMI and
DSI are clocked by different pll clocks to support
various displays at different resolution simultaneously.
The mdss pll driver handles all these display output
interfaces' pll clocks separately. It also handles their
resources through dtsi configuration.
