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.
