[PATCH v11 0/5] arm64: add Ambarella CV75 SoC support

[Long Zhao via B4 Relay]

Add the Ambarella CV75 SoC and EVK support: the board binding, the
RCT clock binding and driver, ARCH_AMBARELLA, the devicetree and
MAINTAINERS.

The clock ID header is added before the devicetree that includes it,
so patch 2 (the clock binding) has to be applied before patch 4 (the
devicetree).

The ambarella vendor prefix and the CV75 secure scratchpad syscon
binding are already in linux-next. This series does not repeat
either of them.

GPIO, UART and pinctrl bindings and drivers are separate series.
This devicetree references those compatibles.

Tested on the CV75 EVK. The board boots. That boot used a local tree
that also includes the GPIO, UART and pinctrl patches.

Changes in v11:
- clk: use builtin_platform_driver(). The Kconfig symbol is bool. (Brian)
- clk: drop CLK_IS_CRITICAL from the core PLL. It has no enable op. (Brian)
- clk: drop the misleading (u64) cast in the div_u64() call. (Brian)
- clk: add .suppress_bind_attrs = true to block sysfs unbind. (Brian)
- clk: drop MODULE_AUTHOR. (Brian)
