Add a SPI device which can be used for testing SPI flash features in sandbox. Also add a cros_ec device since with driver model the Chrome OS EC emulation will not otherwise be available.

* MTD SPI driver for serial flash chips |
||||
|
||||
Required properties: |
||||
- #address-cells, #size-cells : Must be present if the device has sub-nodes |
||||
representing partitions. |
||||
- compatible : Should be the manufacturer and the name of the chip. Bear in |
||||
mind that the DT binding is not U-Boot-only, but in case of |
||||
U-Boot, see spi_flash_params_table table in |
||||
drivers/mtd/spi/sf_params.c for the list of supported chips. |
||||
- reg : Chip-Select number |
||||
- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at |
||||
|
||||
Optional properties: |
||||
- memory-map : Address and size of the flash, if memory mapped. This may |
||||
apply to Intel chipsets, which tend to memory-map flash. |
||||
|
||||
Example: |
||||
|
||||
flash: m25p80@0 { |
||||
#address-cells = <1>; |
||||
#size-cells = <1>; |
||||
compatible = "spansion,m25p80"; |
||||
reg = <0>; |
||||
spi-max-frequency = <40000000>; |
||||
}; |
