Subject: [PATCH v4 06/16] drm/msm/hdmi: drop clock frequency assignment
Date: Sun, 09 Feb 2025 07:04:50 +0200	[thread overview]
Message-ID: <20250209-fd-hdmi-hpd-v4-6-6224568ed87f@linaro.org> (raw)
In-Reply-To: <20250209-fd-hdmi-hpd-v4-0-6224568ed87f@linaro.org>

The only clock which has frequency being set through hpd_freqs is the
"core" aka MDSS_HDMI_CLK clock. It always has the specified frequency,
so we can drop corresponding clk_set_rate() call together with the
hpd_freq infrastructure.
