From f03a562450eef35b785a814005ed164a89dfb2db Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 31 Aug 2023 20:16:55 +0200 Subject: [PATCH] clk: si521xx: Use REGCACHE_FLAT instead of NONE In order to reload registers into the clock generator on resume using regcache_sync(), it is necessary to select one of the regcache types which are not NONE. Since this device has some 7 registers, use the simplest one, FLAT. The regcache code complains about REGCACHE_NONE being selected and generates a WARNING, this fixes that warning.
