Subject: [PATCH 193/224] clk: mediatek: adjust dependency of reset.c to avoid
|
|
unexpectedly being built
|
|
|
|
Changes from v1->v2:
|
|
Add 'select RESET_CONTROLLER' under COMMON_CLK_MEDIATEK and enable
|
|
reset.c to be built when COMMON_CLK_MEDIATEK is selected. That should
|
|
be quite reasonable because the reset controller is tightly embedded
|
|
inside and exported from these clock subsystems. At least it can be found
|
|
on infracfg and pericfg subsystem that both are really fundamental block
|
|
lots of devices must depend on.
|
|
|
|
commit 74cb0d6dde8 ("clk: mediatek: fixup test-building of MediaTek clock
|
|
drivers") can let the build system looking into the directory where the
|
|
clock drivers resides and then allow test-building the drivers.
|
|
|
|
But the change also gives rise to certain incorrect behavior which is
|
|
reset.c being built even not depending on either COMPILE_TEST or
|
|
ARCH_MEDIATEK alternative dependency. To get rid of reset.c being built
|
|
unexpectedly on the other platforms, it would be a good change that the
|
|
file should be built depending on its own specific configuration rather
|
|
than just on generic RESET_CONTROLLER one.
