Subject: [PATCH 02/18] ARM: dts: Configure also interconnect clocks for am3 system timers
Date: Mon, 26 Oct 2020 13:22:06 +0200	[thread overview]
Message-ID: <20201026112222.56894-3-tony@atomide.com> (raw)
In-Reply-To: <20201026112222.56894-1-tony@atomide.com>

We now manage clocksource and clockevent clocks directly with
timer-ti-dm-systimer. In order to use genpd with prm_omap,
GENPD_FLAG_PM_CLK and simple-pm-bus, we need to keep the system
timer related interconnect clocks enabled until clocksource suspend
is done.
