From 89a173dec1b8951696b324880448d781d45f13ca Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 26 Jan 2023 18:05:46 +0100 Subject: [PATCH] drm/vc4: hdmi: Replace hardcoded value by define The 120MHz value hardcoded in the call to max_t to compute the HSM rate is defined in the driver as HSM_MIN_CLOCK_FREQ, let's switch to it so that it's more readable.
