I'm not sure if this patch can be taken via drm-intel in isolation as it is part of a series... Will let you know if I need to make such a request. Thank you.

[Intel-gfx] [PATCH v9 01/11] drm/i915: Use 64-bit division macro
Since the PWM framework is switching struct pwm_state.duty_cycle's datatype to u64, prepare for this transition by using DIV_ROUND_UP_ULL to handle a 64-bit dividend.
