Hi Mike, Stephen,
Here are a couple fixes for the clk core. They are unrelated but overlap in diff context, so I'm sending them together.
Patch 1 makes the clk core honor CLK_OPS_PARENT_ENABLE for clk gate ops. Without this, dumping clk_summary on the MT8192 would cause the system to hang.
Patch 2 reorders the runtime PM call in clk_core_unprepare() to match the order described in its original commit, and the opposite of that in clk_core_prepare().
Changes since v1 - Use clk_core_{enable,disable}_lock() instead of non-locking variant. Reported by Nícolas - Added coverage for clk_core_is_prepared() - Correct sequencing in clk_core_is_enabled() so that runtime PM is handled before parent clock is enabled, matching other functions.
Regards ChenYu
