[PATCH 0/2] clk: add Ambarella CV75 RCT clock controller

[Long Zhao via B4 Relay <devnull+longzhao.ambarella.com@kernel.org>]

Split from the combined CV75 bring-up series.

CLK_AMBARELLA_CV75 depends on ARCH_AMBARELLA || COMPILE_TEST, so the
driver still builds with COMPILE_TEST when the SoC symbol is absent.
The binding uses the ambarella vendor prefix, which is added by the
SoC series and is not in mainline yet; dt_binding_check needs that
prefix. The MAINTAINERS entry for these files is in the SoC series.

Changes since the patches in the combined v9:
- drop the redundant linux/math.h include (Andy)
- use for (unsigned int i = 0; ...) (Andy)
- initialize the spinlock after the allocation succeeds (Andy)
- group the ctrl, frac and ctrl2 offsets in struct cv75_pll_regs (Andy)
