Having a single place where stuff that is absolutely critical for proper SoC operation can be selected is very useful and avoids hard to debug issues due to slightly wrong configs in the long run.As mentioned in the cover letter, please ignore this patch set entirely. The ARCH_MXC is actually used on arm32 too, so it won't work. I'm working on a patchset that will add the Kconfig into drivers/clk/imx/ and in it will add CLK_IMX8MQ. That will fix the clock dependency since the CLK_IMX8MQ will depend on ARCH_MXC and ARM64. I believe the CLK_IMX8QXP will follow the same pattern. As for the SOC_IMX8MQ, all the other vendors have one single config for all the arm64 platforms. TBH, to control every SoC independently it's a little bit of an overkill.
Lucas, We are still waiting for further comments from Olof [1]. But it sounds like SoC specific option is not welcomed on ARM64.
