If anyone has any objections, please let me know. ------------------ From: Michael Trimarchi commit 09018d4bd7994c2c9f775029bc24589bc85f76fa upstream. clk-gate core will take bit_idx through clk_register_gate and then do clk_gate_ops by using BIT(bit_idx), but rtc-sun6i is passing bit_idx as BIT(bit_idx) it becomes BIT(BIT(bit_idx) which is wrong and eventually external gate clock is not enabling. This patch fixed by passing bit index and the original change introduced from below commit.
