Subject: [PATCH v7 4/7] clk: rockchip: rk3588: fix pclk_vo0grf and pclk_vo1grf
Date: Wed, 13 Dec 2023 19:46:49 +0100	[thread overview]
Message-ID: <20231213185114.47565-5-sebastian.reichel@collabora.com> (raw)
In-Reply-To: <20231213185114.47565-1-sebastian.reichel@collabora.com>

Currently pclk_vo1grf is not exposed, but it should be referenced
from the vo1_grf syscon, which needs it enabled. That syscon is
required for HDMI RX and TX functionality among other things.

Apart from that pclk_vo0grf and pclk_vo1grf are both linked gates
and need the VO's hclk enabled in addition to their parent clock.

No Fixes tag has been added, since the logic requiring these clocks
is not yet upstream anyways.
