With this change, pwm_ops->apply() can be used to set pwm_state parameters as usual. [1] https://lore.kernel.org/lkml/20190916140048.GB7488@ulmo/ Changes from v1: - Fixed compilation errors seen when compiling for different archs. Changes from v2: - Fixed %u -> %llu in a dev_dbg in pwm-stm32-lp.c, thanks to kbuild test robot - Added a couple of fixes to pwm-imx-tpm.c and pwm-sifive.c Changes from v3: - Rebased to current tip of for-next. Changes from v4: - Split the patch into two: one for changes to the drivers, and the actual switch to u64 for ease of reverting should the need arise. - Re-examined the patch and made the following corrections: * intel_panel.c: DIV64_U64_ROUND_UP -> DIV_ROUND_UP_ULL (as only the numerator would be 64-bit in this case). * pwm-sti.c: do_div -> div_u64 (do_div is optimized only for x86 architectures, and div_u64's comment block suggests to use this as much as possible).
