regulator: fan53555: fix up the dcdc is disabled when reboot

Before reboot if the DCDC is disabled,
the DCDC is still disabled after restart.
We have an method to workaround:
Use vsel pin to switch the voltage between value in FAN53555_VSEL0
and FAN53555_VSEL1. If VSEL pin is inactive, the voltage of DCDC
are controlled by FAN53555_VSEL0, when we pull vsel pin to active,
they would be controlled by FAN53555_VSEL1.
In this case, we can set FAN53555_VSEL1 to disable dcdc,
So we can make vsel pin to active to disable dcdc,
VSEL pin is inactive to enable DCDC.

rockchip/vcodec: fix crash on decoder buffer empty

On vpu2 register separate interrupt bit and enable bit to different
register. When decoder found a buffer empty error which means the input
stream is not enough for one complete frame decoder will not stop
reading input stream buffer until it reach the end of buffer. This will

In order to avoid this case decoder need to clear the enable bit in the

arm64: dts: rockchip: optimize clks for rk3399 dwc3

1. modify clock-names, according to Heiko's suggestion, clock names
should always be in the scope of the device block (named after what
it supplies), and clock-names are always meant from the perspective
of the individual ip-block.

2. remove unnecessary clocks, refer to rk3399 TRM, aclk_usb3 is the
parent of aclk_usb3otg0/1 and aclk_usb3_grf, and we will enable
aclk_usb3otg0/1 and aclk_usb3_grf, so don't need to enable aclk_usb3
again. In addition, the aclk_usb3_rksoc_axi_perf clk is used for usb3
performance monitor module which we don't use now, so don't need to
enable it.

phy: phy-rockchip-typec: fix rx eq training fail

When do Rx compliance test, PHY is in loopback mode, we
observed that Rx test failed with long cable, and it was
found that equalizer adaptation is not happening properly.
With rx_eq_training forced from PMA, the equalizer adaptation
working fine and Rx test can pass. The root cause is that
the Rx REE component will be turned off when control data
is being received by default PHY configuration. So we need
to unmask REE control data by setting REE control data mask
register, and with this patch, equalizer training will happen
based on the signal coming from controller only.

UPSTREAM: usb: dwc2: Avoid more calls to dwc2_core_reset()

Calls to dwc2_core_reset() are currently very slow, taking at least
150ms (possibly more).  It behooves us to take as many of these calls
out as possible.

It turns out that the calls in dwc2_fs_phy_init() and dwc2_hs_phy_init()
should (as documented in the code) only be needed if we need to do a PHY
SELECT.  That means that if we see that we can avoid the PHY SELECT then
we can avoid the reset.

This patch appears to successfully bypass two resets (one per USB
device) on rk3288-based ARM Chromebooks.

UPSTREAM: usb: dwc2: reduce dwc2 driver probe time

I found that the probe function of dwc2 driver takes much time
when kernel boot up. There are many long delays in the probe
function these take almost 1 second.

This patch trying to reduce unnecessary delay time.

In dwc2_core_reset() I see it use two at least 20ms delays to
wait AHB idle and core soft reset, but dwc2 data book said that
dwc2 core soft reset and AHB idle just need a few clocks (I think
it refers to AHB clock, and AHB clock run at 150MHz in my RK3288
board), so 20ms is too long, delay 1us for wait AHB idle and soft
reset is enough.

And in dwc2_get_hwparams() it takes 150ms to wait ForceHostMode
and ForceDeviceMode valid but in data book it said software must
wait at least 25ms before the change to take effect, so I reduce
this time to 25ms~50ms. By the way, is there any state bit show
that the force mode take effect ? Could we poll curmod bit for
figuring out if the change take effect ?

It seems that usleep_range() at boot time will pick the longest
value in the range. In dwc2_core_reset() there is a very long
delay takes 200ms, and this function run twice when probe, could
any one tell me is this delay time resonable ?

I have tried this patch in my RK3288-evb board. It works well.

UPSTREAM: usb: dwc2: Speed dwc2_get_hwparams() on some host-only ports

On some host-only DWC2 ports (like the one in rk3288) when we set
GUSBCFG_FORCEHOSTMODE in GUSBCFG and then read back, we don't see the
bit set.  Presumably that's because the port is always forced to HOST
mode so there's no reason to implement these status bits.

Since we know dwc2_core_reset() is always called before
dwc2_get_hwparams() and we know dwc2_core_reset() should have set
GUSBCFG_FORCEHOSTMODE whenever hsotg->dr_mode == USB_DR_MODE_HOST, we
can just check hsotg->dr_mode to decide that we can skip the delays in

UPSTREAM: usb: dwc2: Avoid double-reset at boot time

In (usb: dwc2: reset dwc2 core before dwc2_get_hwparams()) we added an
extra reset to the probe path for the dwc2 USB controllers.  This
allowed proper detection of parameters even if the firmware had already
used the USB part.

Unfortunately, this extra reset is quite slow and is affecting boot
speed.  We can avoid the double-reset by skipping the extra reset that
would happen just after the one we added.  Logic that explains why this
is safe:

* As of the CL mentioned above, we now always call dwc2_core_reset() in
  dwc2_driver_probe() before dwc2_hcd_init().

* The only caller of dwc2_hcd_init() is dwc2_driver_probe(), so we're
  guaranteed that dwc2_core_reset() was called before dwc2_hdc_init().

* dwc2_hdc_init() is the only caller that passes an irq other than -1 to
  dwc2_core_init().  Thus if dwc2_core_init() is called with an irq
  other than -1 we're guaranteed that dwc2_core_reset was called before
  dwc2_core_init().

...this allows us to remove the dwc2_core_reset() in dwc2_core_init() if
irq is not < 0.

Note that since "irq" wasn't used in the function dwc2_core_init()
anyway and since select_phy was always set at exactly the same times we
could avoid the reset, we remove "irq" and rename "select_phy" to
"initial_setup" and adjust the callers accordingly.

We initiate dwc2 usb controller in BIOS, dwc2_core_reset() should

UPSTREAM: usb: dwc2: Restore GUSBCFG in dwc2_get_hwparams()

Previously dwc2_get_hwparams() was changing GUSBCFG and not putting it
back the way it was (specifically it set and cleared FORCEHOSTMODE).
Since we want to move dwc2_core_reset() _before_ dwc2_get_hwparams() we
should make sure dwc2_get_hwparams() isn't messing with things in a
permanent way.

Since we're now looking at GUSBCFG, it's obvious that we shouldn't need
all the extra delays if FORCEHOSTMODE was already set.  This will avoid
some delays for any ports that have forced host mode.

arm64: dts: rockchip: disabled the dw-hdmi-audio by default for Sapphire board

The dw-hdmi-audio driver could only work on FB dw-hdmi driver, we can't
use it on DRM display sub-system. So I think it's better to disable the
dw-hdmi-audio by default for Sapphire board, but enable this device node
for excavator-edp and excavator-box boards.

arm64: dts: rockchip: split the backlight device node to Sapphire SoC board

Backlight is the common device node, this would help to reduce
dumplicate code.
