Hi all, This patch series adds I2C and EEPROM support for the Renesas R-Car S4-8 SoC and the Spider development board. It has been tested by reading /sys/bus/nvmem/devices/*/nvmem. All three EEPROMs are empty, except for a (different for each (sub)board) 32-bit value at offset 0x70. As the AT24 EEPROM driver does not set the I2C_M_DMA_SAFE flag (it uses regmap), DMA operation was tested by modifying the i2c-rcar driver to ignore the lack of this flag. For testing, this series and its dependencies (i2c driver updates, pinctrl, clk, ...) can be found at[1]. Thanks for your comments!
