Subject: [PATCH v2 02/22] clk: rockchip: rk3399: Add dummy support for ACLK_VDU clock
Date: Wed, 1 May 2024 16:22:19 +0000 [thread overview]
Message-ID: <20240501162308.875193-3-jonas@kwiboo.se> (raw)
In-Reply-To: <20240501162308.875193-1-jonas@kwiboo.se>
rk3399.dtsi from linux v5.19 and newer try to set VDU clock rate to
400 MHz using an assigned-clock-rates prop of the CRU node.
U-Boot does not use or need this clock so add dummy support for getting
and setting ACLK_VDU clock rate to allow CRU driver to be loaded with an
updated rk3399.dtsi.
