ARM: shmobile: kzm9g: Support Real Time Clock
KZM-A9-GT board has RTC device r2025d at I2C channel 0 with slave address 0x64. This patch enables reading and writing hardware real time clock on KZM-A9-GT board. Interrupt is not yet supported. How to test this patch using user space command. Read RTC # hwclock -r Copy system clock to RTC # hwclock -w Shutdown and power off the board, and wait a while, then power on again. Check RTC still keeps correct date.
