From 8b88f1e9918c173b24b43015cdb713cdde9e4d17 Mon Sep 17 00:00:00 2001 From: Claudiu Beznea Date: Thu, 19 Nov 2020 17:43:14 +0200 Subject: [PATCH 108/247] clk: at91: sama7g5: decrease lower limit for MCK0 rate On SAMA7G5 CPU clock is changed at run-time by DVFS. Since MCK0 and CPU clock shares the same parent clock (CPUPLL clock) the MCK0 is also changed by DVFS to avoid over/under clocking of MCK0 consumers. The lower limit is changed to be able to set MCK0 accordingly by DVFS.
