cadence_qspi.c and cadence_ospi_versal.c call xilinx_pm_request()
directly in a few places, guarded by IS_ENABLED(CONFIG_ZYNQMP_FIRMWARE)
checks. This series replaces those with named weak/strong wrapper
pairs (zynqmp_pm_ospi_init(), zynqmp_pm_ospi_enable_linear_mode(),
zynqmp_pm_ospi_flash_reset()): a no-op or raw-MMIO weak default per
platform, and a firmware-backed override in firmware-zynqmp.c.
Akshay Belsare (6):
power: firmware: zynqmp: add shared request_node() helper
spi: cadence_qspi: Abstract PM node requests behind firmware helper
spi: cadence_ospi_versal: decouple OSPI mux selection from firmware
calls
spi: cadence_qspi: propagate mux-select failure instead of only
logging it
firmware: zynqmp: add OSPI flash reset IOCTL wrapper
spi: cadence_ospi_versal: route OSPI flash reset through firmware
