Subject: [PATCH v2 2/7] bindings: spi-samsung: document the clocks and the clock-name property
Date: Fri, 08 Jul 2016 23:46:36 +0900
Message-ID: <1467989201-14661-3-git-send-email-andi.shyti@samsung.com> (raw)
In-Reply-To: <1467989201-14661-1-git-send-email-andi.shyti@samsung.com>

These two properties were not documented but used in the spi
dts. Add the related documentation.
