From 689f9cf6aa9edff89c4d4d3b843f500fc5582300 Mon Sep 17 00:00:00 2001 From: Chris Packham Date: Thu, 11 Apr 2019 22:22:51 +1200 Subject: [PATCH] arm: mvebu: NAND clock support for MSYS devices 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.
