Subject: [PATCH v5 1/6] ARM: DT: STi: stihxxx-b2120: Add pulse-width properties to ssc2 & ssc3
Date: Thu, 3 Sep 2015 18:59:49 +0100 [thread overview]
Message-ID: <1441303194-28211-2-git-send-email-peter.griffin@linaro.org> (raw)
In-Reply-To: <1441303194-28211-1-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.
Signed-off-by: Peter Griffin <peter.griffin@linaro.org>
Acked-by: Lee Jones <lee.jones@linaro.org>
