Subject: [PATCH 1/6] clk: sunxi: Add NAND clocks and resets
Date: Wed, 13 Jul 2022 22:15:21 -0500 [thread overview]
Message-ID: <20220714031526.33697-2-samuel@sholland.org> (raw)
In-Reply-To: <20220714031526.33697-1-samuel@sholland.org>
Currently NAND clock setup is done in board code, both in SPL and in
U-Boot proper. Add the NAND clocks/resets here so they can be used by
the "full" NAND driver once it is converted to the driver model.
The bit locations are copied from the Linux CCU drivers.
