Commit 761ed4a94582 ("tty: serial_core: convert uart_close to use
tty_port_close") created a case where a port used for a console does not
get shutdown on tty closing. Then a call to uart_tx_stopped() segfaults
because the tty is NULL. This could be fixed to restore old behavior,
but we also want to allow tty_ports to work without a tty attached. So
this change to allow a NULL tty_struct is needed either way.

Add a node for a GPIO-based FAN cooling device for msm8996
CV2X boards. This GPIO has a single speed and can be controlled
from user space.

Currently, FULL_SOC and MONOTONIC_SOC registers are updated
multiple times when the recharge SOC threshold is close enough to
trigger the recharging frequently. This was leading to a SOC
fluctuation when SOC masking algorithm is enabled.
Rearrange charge_full_update used in SOC masking algorithm such
that FULL_SOC and MONOTONIC_SOC registers are updated just once
when the charge_full flag is cleared.
Also, when the device is rebooted/shutdown and if charge_full
flag is set, write to FULL_SOC with battery_soc and a full value
to MONOTONIC_SOC registers. This helps to maintain the same SOC
across a device reboot.

Add new parameters to account for different MCUs that can
be used with this driver. These devices have different reset
sequences and number of bits per word supported via SPI. Add
bindings for the mpc5746c controller and make the reset signal
optional.

The WFD setup path has few register writes. If the MDP clocks
aren't switched on, the register access might cause SMMU
faults. Turn on the clocks, before calling WFD setup.
