Subject: [PATCH v3 1/6] ARM: DT: STi: stihxxx-b2120: Add pulse-width properties to ssc2 & ssc3
Date: Fri, 28 Aug 2015 18:52:37 +0100	[thread overview]
Message-ID: <1440784362-31217-2-git-send-email-peter.griffin@linaro.org> (raw)
In-Reply-To: <1440784362-31217-1-git-send-email-peter.griffin-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>

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