Pull pwm fixes from Uwe Kleine-König: "A set of fixes for pwm core and various drivers The first three patches handle clk_get_rate() returning 0 (which might happen for example if the CCF is disabled). The first of these was found because this triggered a warning with clang, the two others by looking for similar issues in other drivers. The remaining three fixes address issues in the new waveform pwm API. Now that I worked on this a bit more, the finer details and corner cases are better understood and the code is fixed accordingly" * tag 'pwm/for-6.15-rc2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux: pwm: axi-pwmgen: Let .round_waveform_tohw() signal when request was rounded up pwm: stm32: Search an appropriate duty_cycle if period cannot be modified pwm: Let pwm_set_waveform() succeed even if lowlevel driver rounded up pwm: fsl-ftm: Handle clk_get_rate() returning 0 pwm: rcar: Improve register calculation pwm: mediatek: Prevent divide-by-zero in pwm_mediatek_config()
