2018-04-09ARM: dts: zynq: Add generic compatible string for I2C EEPROMJavier Martinez Canillas
The at24 driver allows to register I2C EEPROM chips using different vendor and devices, but the I2C subsystem does not take the vendor into account when matching using the I2C table since it only has device entries. But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table.

2018-04-06ARM: am33xx: Inhibit re-initialization of DDR during RTC-onlyRuss Dill
This inhibits the re-inititialization of DDR during an RTC-only resume. If this is not done, an L3 NOC error is produced as the DDR gets accessed before the re-init has time to complete.

2018-04-06ARM: AM43xx: Add support for RTC only + DDR in self-refresh modeTero Kristo
Kernel stores information to the RTC_SCRATCH0 and RTC_SCRATCH1 registers for wakeup from RTC-only mode with DDR in self-refresh. Parse these registers during SPL boot and jump to the kernel resume vector if the device is waking up from RTC-only modewith DDR in Self-refresh. The RTC scratch register layout used is: SCRATCH0 : bits00-31 : kernel resume address SCRATCH1 : bits00-15 : RTC magic value used to detect valid config SCRATCH1 : bits16-31 : board type information populated by bootloader During the normal boot path the SCRATCH1 : bits16-31 are updated with the eeprom read board type data. In the rtc_only boot path the rtc scratchpad register is read and the board type is determined and correspondingly ddr dpll parameters are set. This is done so as to avoid costly i2c read to eeprom. RTC-only +DRR in self-refresh mode support is currently only enabled for am43xx_evm_rtconly_config. This is not to be used with epos evm builds.
