Subject: [PATCH 2/9] ARM: OMAP2+: Probe PRCM first to probe l4_wkup with simple-pm-bus
Date: Mon, 26 Oct 2020 13:10:42 +0200 [thread overview]
Message-ID: <20201026111049.54835-3-tony@atomide.com> (raw)
In-Reply-To: <20201026111049.54835-1-tony@atomide.com>
In preparation for probing the interconnects with simple-pm-bus to
make use of genpd, we need to probe the always-on PRCM first for the
clocks needed by l4_wkup instance.
