Subject[PATCH v7 00/13] Convert period and duty cycle to u64
Date
Changes from v6:
- Split out the driver changes out into separate patches, one patch per file
for ease of reviewing.

Changes from v5:
- Dropped the conversion of struct pwm_capture to u64 for reasons mentioned
in https://www.spinics.net/lists/linux-pwm/msg11541.html

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).

Changes from v3:
- Rebased to current tip of for-next.

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 v1:
- Fixed compilation errors seen when compiling for different archs.

Reworked the change pushed upstream earlier [1] so as to not add an extension
to an obsolete API. With this change, pwm_ops->apply() can be used to set
pwm_state parameters as usual.
