Subject: [PATCH 2/6] ARM: dts: r7s72100: Add SPIBSC clocks
Date: Mon, 2 Dec 2019 22:45:15 -0500
Message-ID: <20191203034519.5640-3-chris.brandt@renesas.com> (raw)
In-Reply-To: <20191203034519.5640-1-chris.brandt@renesas.com>

The SPIBSC-0 clock is marked as critical because for XIP systems, this
is the SPI flash controller it will boot from and the kernel will also
be running from so it cannot be turned off.
