-I2C for Atmel platforms
-
-Required properties :
-- compatible : Must be one of:
-       "atmel,at91rm9200-i2c",
-       "atmel,at91sam9261-i2c",
-       "atmel,at91sam9260-i2c",
-       "atmel,at91sam9g20-i2c",
-       "atmel,at91sam9g10-i2c",
-       "atmel,at91sam9x5-i2c",
-       "atmel,sama5d4-i2c",
-       "atmel,sama5d2-i2c",
-       "microchip,sam9x60-i2c".
-- reg: physical base address of the controller and length of memory mapped
-     region.
-- interrupts: interrupt number to the cpu.
-- #address-cells = <1>;
-- #size-cells = <0>;
-- clocks: phandles to input clocks.
-
-Optional properties:
-- clock-frequency: Desired I2C bus frequency in Hz, otherwise defaults to 100000
-- dmas: A list of two dma specifiers, one for each entry in dma-names.
-- dma-names: should contain "tx" and "rx".
-- atmel,fifo-size: maximum number of data the RX and TX FIFOs can store for FIFO
-  capable I2C controllers.
-- i2c-sda-hold-time-ns: TWD hold time, only available for:
-       "atmel,sama5d4-i2c",
-       "atmel,sama5d2-i2c",
-       "microchip,sam9x60-i2c".
-- scl-gpios: specify the gpio related to SCL pin
-- sda-gpios: specify the gpio related to SDA pin
-- pinctrl: add extra pinctrl to configure i2c pins to gpio function for i2c
-  bus recovery, call it "gpio" state
-- Child nodes conforming to i2c bus binding
