Subject: [PATCH] drm/vc4: hdmi: Fix hdmi_enable_4kp60 detection
|
|
|
|
In order to support higher HDMI frequencies, users have to set the
|
|
hdmi_enable_4kp60 parameter in their config.txt file.
|
|
|
|
We were detecting this so far by calling clk_round_rate() on the core
|
|
clock with the frequency we're supposed to run at when one of those
|
|
modes is enabled. Whether or not the parameter was enabled could then be
|
|
inferred by the returned rate since the maximum clock rate reported by
|
|
the firmware was one of the side effect of setting that parameter.
|
|
|
|
However, the recent clock rework we did changed what clk_round_rate()
|
|
was returning to always return the minimum allowed, and thus this test
|
|
wasn't reliable anymore.
|
|
|
|
Let's use the new clk_get_max_rate() function to reliably determine the
|
|
maximum rate allowed on that clock and fix the 4k@60Hz output.
|
|
|
|
Fixes: e9d6cea2af1c ("clk: bcm: rpi: Run some clocks at the minimum rate allowed")
