Update DTS file with required clock frequencies for the i2c client devices existing on sdp4430. Add the twl6030 node inside the i2c1 controller node. This is the minimal support needed to boot OMAP4 boards without any crash. The support for all the features included in this MFD will be added later. Add the RTC submodule inside the twl node. Add tmp105 temperature sensor in i2c3 Add bh1780 Ambient Light Sensor in i2c3 Add hmc5843 3-Axis Digital Compass in i2c4 Signed-off-by: Benoit Cousson <redacted> Cc: Grant Likely <redacted> --- arch/arm/boot/dts/omap4-sdp.dts | 53 +++++++++++++++++++++++++++++++++++++++ 1 files changed, 53 insertions(+), 0 deletions(-)
