do {
val = hdmi_readb(hdmi, HDMI_PHY_STAT0) & HDMI_PHY_TX_PHY_LOCK;

while is break if pll is not lock yet, the real lock status may
be after the dw_hdmi_enable_video_path.

This bug is fixed in commit <a479fa5417b12fdf7aef8e41fdb99393e1c28581>
(FROMLIST: drm: bridge: dw-hdmi: Fix the PHY power up sequence)

FROMLIST: drm: bridge: dw-hdmi: Fix the PHY power up sequence

When powering the PHY up we need to wait for the PLL to lock. This is
done by polling the TX_PHY_LOCK bit in the HDMI_PHY_STAT0 register
(interrupt-based wait could be implemented as well but is likely
overkill). The bit is asserted when the PLL locks, but the current code
incorrectly waits for the bit to be deasserted. Fix it, and while at it,
replace the udelay() with a sleep as the code never runs in
non-sleepable context.

To be consistent with the power down implementation move the poll loop
to the power off function.

FROMLIST: drm: bridge: dw-hdmi: Fix the PHY power down sequence

The PHY requires us to wait for the PHY to switch to low power mode
after deasserting TXPWRON and before asserting PDDQ in the power down
sequence, otherwise power down will fail.

The PHY power down can be monitored though the TX_READY bit, available
through I2C in the PHY registers, or the TX_PHY_LOCK bit, available
through the HDMI TX registers. As the two are equivalent, let's pick the
easier solution of polling the TX_PHY_LOCK bit.

The power down code is currently duplicated in multiple places. To avoid
spreading multiple calls to a TX_PHY_LOCK poll function, we have to
refactor the power down code and group it all in a single function.

Tests showed that one poll iteration was enough for TX_PHY_LOCK to
become low, without requiring any additional delay. Retrying the read
five times with a 1ms to 2ms delay between each attempt should thus be
more than enough.

UPSTREAM: drm: bridge: dw-hdmi: Handle overflow workaround based on device version

Use the device version queried at runtime instead of the device type
provided through platform data to handle the overflow workaround. This
will make support of other SoCs integrating the same HDMI TX controller
version easier.

Among the supported platforms only i.MX6DL and i.MX6Q have been
identified as needing the workaround. Disabling it on Rockchip RK3288
(which integrates a v2.00a controller) didn't produce any error or
artifact.

UPSTREAM: drm: bridge: dw-hdmi: Reject invalid product IDs

The DWC HDMI TX can be recognized by the two product identification
registers. If the registers don't read as expect the IP will be very
different than what the driver has been designed for, or will be
misconfigured in a way that makes it non-operational (invalid memory
address, incorrect clocks, ...). We should reject this situation with an
error.

While this isn't critical for proper operation with supported IPs at the
moment, the driver will soon gain automatic device-specific handling
based on runtime device identification. This change makes it easier to
implement that without having to default to a random guess in case the
device can't be identified.

While at it print a readable version number in the device identification
message instead of raw register values.

CHROMIUM: xhci: fix USB3 device undetected after resume

Some xHC controllers (e.g. Rockchip rk3399) integrated in
DWC3 IP, will be powered down in S3, and reinitialized after
resume.

However, if a USB3 device is plugged before system enter S3,
the device will be disconnected after resume because of xHC
lose power. And the device can't be detected again even if
we reinitialize xHC. In this case, CCS and CSC is '0' and
can't reflect the current state of the port, also the link
state stays in Rx.Detect.

So try to do warm reset on resume to reset USB3 device to
the default state, also reset a USB3 link, and re-exchange
link configuration information.

UPSTREAM: ARM: DTS: Fix register map for virt-capable GIC

Since everybody copied my own mistake from the DT binding example,
let's address all the offenders in one swift go.

Most of them got the CPU interface size wrong (4kB, while it should
be 8kB), except for both keystone platforms which got the control
interface wrong (4kB instead of 8kB).

In a few cases where I knew for sure what implementation was used,
I've added the "arm,gic-400" compatible string. I'm 99% sure that
this is what everyone is using, but short of having the TRM for
all the other SoCs, I've left them alone.
