    Subject[PATCH v3 0/7] drm/vc4: Fix the core clock behaviour
    From
    Date
    Hi,

    Those patches used to be part of a larger clock fixes series:
    https://lore.kernel.org/linux-clk/20220715160014.2623107-1-maxime@cerno.tech/

    However, that series doesn't seem to be getting anywhere, so I've split out
    these patches that fix a regression that has been there since 5.18 and that
    prevents the 4k output from working on the RaspberryPi4.

    Hopefully, we will be able to merge those patches through the DRM tree to avoid
    any further disruption.

    Let me know what you think,
    Maxime

    Changes in v3:
    - Return UINT_MAX when the firmware call fails in the _get_max_rate function
    - Link to v2: https://lore.kernel.org/r/20220815-rpi-fix-4k-60-v2-0-983276b83f62@cerno.tech

    Changes in v2:
    - Dropped the clock patches, made an ad-hoc function in the firmware driver
    - Link to v1: https://lore.kernel.org/r/20220815-rpi-fix-4k-60-v1-0-c52bd642f7c6@cerno.tech
