Subject: [PATCH v4 04/16] drm/msm/hdmi: move the alt_iface clock to the hpd list
Date: Sun, 09 Feb 2025 07:04:48 +0200	[thread overview]
Message-ID: <20250209-fd-hdmi-hpd-v4-4-6224568ed87f@linaro.org> (raw)
In-Reply-To: <20250209-fd-hdmi-hpd-v4-0-6224568ed87f@linaro.org>

According to the vendor kernel [1] , the alt_iface clock should be
enabled together with the rest of HPD clocks, to make HPD to work
properly.
