Subject: [PATCH v3 0/3] pinctrl: qcom: Introduce Pinctrl/GPIO for SM8650

The SM8650 Top Level Mode Multiplexer supports 211 GPIOs,
and the usual UFS Reset, SDC Clk/Cmd/Data special pins.

An handful of pins can have their IRQ generated by the PDC
module, and for this support for the new wakeup_present &
wakeup_enable_bit is required to allow the "wakeup" event
to be passed to PDC and generate an interrupt or a wakeup
system event.

As SM8550, it also supports the i2c_pull_bit bit to enable the
on-SoC load resistor for I2C busses.

Dependencies: None

For convenience, a regularly refreshed linux-next based git tree containing
all the SM8650 related work is available at:
