Subject: [PATCH v2 07/13] clk: Add clock driver for sun50i-a64
Date: Thu, 25 May 2023 01:43:22 +0200	[thread overview]
Message-ID: <20230524234328.82741-8-jmaselbas@zdiv.net> (raw)
In-Reply-To: <20230524234328.82741-1-jmaselbas@zdiv.net>

Clock driver is adapted from Linux.
During clock init, the pll-cpu is switched to 1.2GHz, the same is done
for the pll-periph0-2x as recommended.
