From d36edb048f48babb3fbf9a4b249df115b7fab152 Mon Sep 17 00:00:00 2001 From: Tony Lindgren <tony@atomide.com> Date: Mon, 16 Nov 2020 12:57:13 +0200 Subject: [PATCH 01/17] clk: ti: am437x: Keep am4 l3 main clock always on for genpd In order for suspend and resume to work with genpd on am4, we must keep l3 main clock always on. Otherwise prm_omap driver will shut down the l3 main clock on suspend when simple-pm-bus and GENPD_FLAG_PM_CLK are used. Note that we already keep the l3 main clock always on with the legacy platform code. Later on we may want to start managing the l3 main clock with a dedicated interconnect driver instead of using simple-pm-bus and GENPD_FLAG_PM_CLK.
