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: Fix the name of the PHY reset macros

The PHY reset signal is controlled by bit PHYRSTZ in the MC_PHYRSTZ
register. The signal is active low on Gen1 PHYs and active high on Gen2
PHYs. The driver toggles the signal high then low, which is correct for
all currently supported platforms, but the register values macros are
incorrectly named. Replace them with a single macro named after the bit,
and add a comment to the source code to explain the behaviour.

The driver's behaviour isn't changed by this rename, the code will still
need to be fixed to support Gen1 PHYs.

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

based on runtime device identification. This change makes it easier to

device can't be identified.

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.
