Subject: [PATCH] clk: qcom: fix some Kconfig corner cases
Date:   Tue,  1 Aug 2023 12:56:32 +0200

From: Arnd Bergmann <arnd@arndb.de>

The SM_GCC_8550 symbol and others can only be built for ARM64 or when
compile testing, but it gets selected by other drivers that can also be
built for 32-bit ARCH_QCOM when not compile testing, which results in
a Kconfig warning:

WARNING: unmet direct dependencies detected for SM_GCC_8550
  Depends on [n]: COMMON_CLK [=y] && COMMON_CLK_QCOM [=m] && (ARM64 || COMPILE_TEST [=n])
  Selected by [m]:
  - SM_GPUCC_8550 [=m] && COMMON_CLK [=y] && COMMON_CLK_QCOM [=m]
  - SM_VIDEOCC_8550 [=m] && COMMON_CLK [=y] && COMMON_CLK_QCOM [=m]

Add further 'depends on' statements to tighten this in a way that
avoids the missing dependencies.
