[PATCH 00/10] Ambarella CV75 SoC minimal bring-up

This series adds minimal Ambarella CV75 support sufficient for early
bring-up with a serial console.

It introduces DT bindings and drivers for the RCT clock controller,
pinctrl, and UART, plus ARCH_AMBARELLA, a minimal CV75 EVK device tree,
arm64 defconfig entries, and a MAINTAINERS entry.

The goal of this first submission is a small, reviewable console-capable
baseline. Further SoC peripherals can follow in later series.

The series is based on linux-next. It has been booted on CV75
hardware with the serial console working.

Testing:
 - Booted to console on CV75 EVK with initramfs
 - scripts/checkpatch.pl --strict
 - make dt_binding_check DT_SCHEMA_FILES=ambarella

Long Zhao (10):
  dt-bindings: arm: add Ambarella CV75 platforms
  dt-bindings: soc: add Ambarella secure scratchpad
  dt-bindings: clock: add Ambarella CV75 RCT clock controller
  dt-bindings: pinctrl: add Ambarella CV75 pinctrl
  dt-bindings: serial: add Ambarella UART
  clk: ambarella: add CV75 CCU driver
  pinctrl: ambarella: add Ambarella pin controller
  serial: ambarella: add Ambarella UART driver
  arm64: ambarella: add ARCH_AMBARELLA and CV75 EVK DT
  MAINTAINERS: add ARM/AMBARELLA SoC support
