Phong Hoang c60a31db39 clocksource/drivers/sh_cmt: Fix wrong setting if don't request IRQ for clock source channel ... [ Upstream commit be83c3b6e7b8ff22f72827a613bf6f3aa5afadbb ] If CMT instance has at least two channels, one channel will be used as a clock source and another one used as a clock event device. In that case, IRQ is not requested for clock source channel so sh_cmt_clock_event_program_verify() might work incorrectly. Besides, when a channel is only used for clock source, don't need to re-set the next match_value since it should be maximum timeout as it still is. On the other hand, due to no IRQ, total_cycles is not counted up when reaches compare match time (timer counter resets to zero), so sh_cmt_clocksource_read() returns unexpected value. Therefore, use 64-bit clocksoure's mask for 32-bit or 16-bit variants will also lead to wrong delta calculation. Hence, this mask should correspond to timer counter width, and above function just returns the raw value of timer counter register.
