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 earlycon exit 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. Changes in V3: - Define common ICC APIs in geni-se driver and use it across geni based I2C,SPI and UART driver.
