Subject: [PATCH v3 7/7] ARM: bcm2835: Tie SPI clock to the core clock rate.
Date: Mon, 8 Jun 2015 16:59:00 -0700 [thread overview]
Message-ID: <1433807940-15328-7-git-send-email-eric@anholt.net> (raw)
In-Reply-To: <1433807940-15328-1-git-send-email-eric@anholt.net>
We were previously using a fixed clock declared in the 2835 DT, but
it's actually the core clock, and it might not be the same if you had
adjusted it using the firmware's config.txt.
