big patch into patchset. So please use, test and applied! Thanks.

config.
Also, cleanup for cros config.

There's no reason to force the command line at this point.
Forcing the command like makes it pretty hard to switch between eMMC and
SD card boots because the old command line forced the root filesystem to
/dev/mmcblk0p3 vs. depthcharge automatically inserting the right UUID
based on where it found the kernel.
BUG=None
TEST=I see my command line now.

The trackpad bits in the DTS needed some love. This adds some basic
infrastructure support in the main gru dts file and then adds the
specific trackpad used on kevin-r0 and kevin-r1. For now just duplicate
between kevin-r0 and kevin-r1 and we'll decide if we want to share
later (perhaps we want an "atmel" snippet?).
Note that gpio-keymap here makes the driver appear as a trackpad rather
than a touchscreen (driver assumes that anything with buttons is a
trackpad). Input entry corresponding to the button on the trackpad was
found by experimentation as suggested in the device tree bindings.
BUG=chrome-os-partner:52637
TEST=With series, trackpad works in browser; button works.

Whenever the current temperature is updated, the trip points immediately
below and above the current temperature are found. A sensor driver
callback `set_trips' is then called with the temperatures.
Lastly, The sensor will trigger the hardware high temperature interrupts
to increase the sampleing rate and throttle frequency to limit the temperature
rising When performing passive cooling.

With interrupt driven thermal zones we pass the lower and upper temperature
on which shall be acted, so in the governor we have to act on the exact lower
temperature to be consistent. Otherwise an interrupt may be generated on the
exact lower temperature, but the bang bang governor does not react.

The .get_trend callback in struct thermal_zone_device_ops has the prototype:
int (*get_trend) (struct thermal_zone_device *, int,
enum thermal_trend *);
whereas the .get_trend callback in struct thermal_zone_of_device_ops has:
int (*get_trend)(void *, long *);
Streamline both prototypes and add the trip argument to the OF callback
aswell and use enum thermal_trend * instead of an integer pointer.
While the OF prototype may be the better one, this should be decided at
framework level and not on OF level.

This adds support for hardware-tracked trip points to the device tree
thermal sensor framework.
The framework supports an arbitrary number of trip points. Whenever
the current temperature is updated, the trip points immediately
below and above the current temperature are found. A .set_trips
callback is then called with the temperatures. If there is no trip
point above or below the current temperature, the passed trip
temperature will be -INT_MAX or INT_MAX respectively. In this callback,
the driver should program the hardware such that it is notified
when either of these trip points are triggered. When a trip point
is triggered, the driver should call `thermal_zone_device_update'
for the respective thermal zone. This will cause the trip points
to be updated again.
If .set_trips is not implemented, the framework behaves as before.
This patch is based on an earlier version from Mikko Perttunen

When we use the MIPI screen, the driver will unprepare and disable
the phy_cfg, it will diable its parent pclk_vio:
dw_mipi_dsi_phy_init
--> clk_disable_unprepare
--> clk_disable
--> clk_core_disable(core->parent)
The pclk_vio supply power for pclk_vio_grf, hence, disable pclk_vio_grf will
cause other drivers failed to operate GRF.

commit 61b914eb81 ("mmc: sdhci-of-arasan: add phy support for
sdhci-of-arasan") introduce phy support for arasan. According to
the vendor's databook, we should make sure the phy is in poweroff
stat before we configure the clk stuff. Otherwise it may cause
some IO sample timing issue from the test. But we don't need this
extra operation while running in non HS200/HS400 mode since phy
doesn't trigger sampling block.

This patch add some optional configuration for dt. freq-sel can be used
to decide the phy sample clk in order to match the real freq of emmc
controller. dr-sel can be configured to match the requirement of different
drive strength of phy IO. opdelay should be used to adjust the output
delay for clk IO and data IO, which is useful for sloving timing issue.

We must not to adjust the port order, cause the port id is mapping
to VOP type. Current driver just hardcode that VOP Lit is ID 0, and
VOP Big is ID 1.
ret = rockchip_drm_encoder_get_mux_id(dp->dev->of_node, encoder);
if (ret)
val = dp->data->lcdsel_lit | dp->data->lcdsel_mask;
else
val = dp->data->lcdsel_big | dp->data->lcdsel_mask;
Besides eDP could work well with VOP Lit, so we need to revert this
hack. Just revert commit 602f4f79c8.
