+Subject: [PATCH] ARM: BCM53016: MR32: convert to Broadcom iProc I2C Driver
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+replaces the bit-banged i2c-gpio provided i2c functionality
+with the hardware in the SoC.
+
+During review of the MR32, Florian Fainelli pointed out that the
+SoC has a real I2C-controller. Furthermore, the connected pins
+(SDA and SCL) would line up perfectly for use. Back then I couldn't
+get it working though and I left it with i2c-gpio (which worked).
+
+Now we know the reason: the interrupt was incorrectly specified.
+(Hence, this patch depends on Florian Fainelli's
+"ARM: dts: BCM5301X: Fix I2C controller interrupt" patch).
