From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chris Packham Date: Sat, 16 Feb 2019 11:49:00 +1300 Subject: [U-Boot] [PATCH v2 3/5] arm: mvebu: NAND clock support for MSYS devices In-Reply-To: <20190215224902.28351-1-judge.packham@gmail.com> References: <20190215224902.28351-1-judge.packham@gmail.com> Message-ID: <20190215224902.28351-4-judge.packham@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de One difference with the integrated CPUs is that they use a different clock control block to the Armada devices. Update mvebu_get_nand_clock() accordingly. Signed-off-by: Chris Packham --- This could probably be squashed into the previous change. I was trying to separate things to aid review but it's hard to do so and keep bisectability.
