[ARM] 5395/1: RealView: Add support for the DS1338 RTC chip
This chip is on the I2C bus on the RealView and Versatile boards. The patch adds the i2c_board_info definition for this device and registers it with the I2C subsystem. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
