Subject: [PATCH 01/12] ARM: DT: STi: stihxxx-b2120: Add pulse-width properties to ssc2 & ssc3
Date: Wed, 24 Jun 2015 16:10:59 +0100	[thread overview]
Message-ID: <1435158670-7195-2-git-send-email-peter.griffin@linaro.org> (raw)
In-Reply-To: <1435158670-7195-1-git-send-email-peter.griffin@linaro.org>

Adding these properties makes the I2C bus to the demodulators much
more reliable, and we no longer suffer from I2C errors when tuning.
