Subject: [PATCH 5.7 088/477] clk: sprd: fix compile-testing
From: Arnd Bergmann <arnd@...db.de>
[ Upstream commit b5f73d47f34b238221ac771b5fe4907df621d7cb ]
I got a build failure with CONFIG_ARCH_SPRD=m when the
main portion of the clock driver failed to get linked into
the kernel:
ERROR: modpost: "sprd_pll_sc_gate_ops" [drivers/clk/sprd/sc9863a-clk.ko] undefined!

This is a combination of two trivial bugs:
- A platform should not be 'tristate', it should be a 'bool' symbol
like the other platforms, if only for consistency, and to avoid
surprises like this one.
- The clk Makefile does not traverse into the sprd subdirectory
if the platform is disabled but the drivers are enabled for
compile-testing.
Fixing either of the two would be sufficient to address the link failure,
but for correctness, both need to be changed.
Fixes: 2b1b799d7630 ("arm64: change ARCH_SPRD Kconfig to tristate")
Fixes: d41f59fd92f2 ("clk: sprd: Add common infrastructure")
