A new request arrives after a NULL request was sent to the mmc_queue,
which is waiting for completion of a former request.

Currently driver doesn't prevent system suspend if UART port is
being used. This change adds support to prevent system suspend
when UART port is opened/under used. With this feature, wakelock
is acquire when UART port is being opened and release when UART
port is being closed.
To enable this feature, set use_pm platform data with required
UART port.
Also document use_pm pdata usage with device tree binding.

GSBI based UART is used in shared mode. Hence this driver only
supports configuring Tx and Rx GPIOs with configuring GSBI control
register with I2C/UART Shared mode protocol.
Add support in this driver for 4-wire UART related configuration
i.e.GPIOs (i.e. Tx, Rx, CTS, RFR signal lines) and programming
GSBI control register with UART mode protocol.
4-wire UART related configuration is done based on platform data
variable config_gpio.
For 4-wire UART, set config_gpio as 4 to configre all 4 GPIOs.
For 2-wire UART, set config_gpio as 1 to configure only Tx and Rx
GPIOs.
Also document added new pdata and their usage with device tree.

During constant voltage charging, the BMS reports a SoC calculated
by linearly interpolating battery current. However, sometimes the
charger does not immediately stop at -100 mA, and sometimes dips a bit
lower. This causes the BMS to report > 100% SoC and may cause a bad
user experience.
Fix this by clamping the linearly interpolated SoC to [0, 100].

Upon interface suspend driver performs suspend on data channel
first and then on control channel. In case if suspend aborts
due to pending transfer on control channel, driver is not
undoing data channel suspend. This causes stall on data channel.
Fix the problem by performing suspend check on control channel
first. In this case if suspend aborts on control channel, driver
does not have to undo anything to abort interface suspend. Once
data channel suspend succeeds driver performs suspend on control
channel.

Commit: b7434561, "USB: dwc3: Add support for basic OTG in superspeed
mode" introduced regression by not putting hardware in LPM on bootup
without USB cable connected.
During boot-up external transceiver driver may notify initial BSV
and ID events to OTG driver even if they are not changed. Since,
ext_xceiv driver brings hardware out of LPM before notifying
events to OTG, hence, schedule state-machine which then takes care
of putting hardware in LPM accordingly.

Rx buffers are freed after user space consumes them. This results in

Don't queue the Rx buffer immediately. Defer it till user space consumes

degradation. The Rx buffers will be freed when interface is suspended

The clocks for these can be selected between master_clk or

if clk_gating is enabled using DWC3's GCTL register, hence,
select master_clk as RAM clock using QSCRATCH.
This allows other BAMs to access USB RAMs when clock gating is enabled
via DWC3's GCTL. Otherwise issues are seen where RAM clocks get turned
