Subject: [PATCH v1 1/3] arm: at91: fix clock to mci1 for at91sam9263
Date: Wed, 2 Jan 2019 21:26:09 +0100 [thread overview]
Message-ID: <20190102202611.6530-2-sam@ravnborg.org> (raw)
In-Reply-To: <20190102202611.6530-1-sam@ravnborg.org>
at91_add_device_mci() was missing configuration of PIOA6
when configuring mci1.
With this fix we can read data from SD card with at91sam9263ek,
when built without DT.
Building without a DT is required when we do a bootstrap build.
The other at91samxxx_devices was checked - only the 9263 was
missing the CLK configuration for mci1.
