[PATCH 4.2 045/258] ARM: dts: omap3-beagle: make i2c3, ddc and tfp410 gpio work again

From: Greg Kroah-Hartman

4.2-stable review patch. If anyone has any objections, please let me know.

------------------

From: Carl Frederik Werner <frederik@xxxxxxx>

commit 3a2fa775bd1d0579113666c1a2e37654a34018a0 upstream.

Let's fix pinmux address of gpio 170 used by tfp410 powerdown-gpio.

According to the OMAP35x Technical Reference Manual
CONTROL_PADCONF_I2C3_SDA[15:0] 0x480021C4 mode0: i2c3_sda
CONTROL_PADCONF_I2C3_SDA[31:16] 0x480021C4 mode4: gpio_170
the pinmux address of gpio 170 must be 0x480021C6.

The former wrong address broke i2c3 (used by hdmi ddc), resulting in
kernel message:
omap_i2c 48060000.i2c: controller timed out
