[PATCH V2 0/8] Add interconnect support to QSPI and QUP drivers

[Akash Asthana <akashast-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>]

dt-binding patch for QUP drivers.
 - https://patchwork.kernel.org/patch/11436621/ [Convert QUP bindings
	to YAML and add ICC, pin swap doc]

dt-binding patch for QSPI.
 - https://patchwork.kernel.org/patch/11436719/ [Convert QSPI binding
	to YAML and add interconnect doc]

High level design:
 - QUP wrapper/common driver.
   Vote for QUP core on behalf of earlycon from probe.
   Remove BW vote during sys suspend call

 - SERIAL driver.
   Vote only for CPU/CORE path because driver is in FIFO mode only
   Vote/unvote from qcom_geni_serial_pm func.
   Bump up the CPU vote from set_termios call based on real time need

 - I2C driver.
   Vote for CORE/CPU/DDR path
   Vote/unvote from runtime resume/suspend callback
   As bus speed for I2C is fixed from probe itself no need for bump up.

 - SPI QUP driver.
   Vote only for CPU/CORE path because driver is in FIFO mode only
   Vote/unvote from runtime resume/suspend callback
   Bump up CPU vote based on real time need per transfer.

 - QSPI driver.
   Vote only for CPU path
   Vote/unvote from runtime resume/suspend callback
   Bump up CPU vote based on real time need per transfer.


Changes in V2:
 - Add devm_of_icc_get() API interconnect core.
 - Add ICC support to common driver to fix earlyconsole crash.
