1*4882a593Smuzhiyun* MTD SPI driver for serial flash chips 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunRequired properties: 4*4882a593Smuzhiyun- #address-cells, #size-cells : Must be present if the device has sub-nodes 5*4882a593Smuzhiyun representing partitions. 6*4882a593Smuzhiyun- compatible : Should be the manufacturer and the name of the chip. Bear in 7*4882a593Smuzhiyun mind that the DT binding is not U-Boot-only, but in case of 8*4882a593Smuzhiyun U-Boot, see spi_flash_params_table table in 9*4882a593Smuzhiyun drivers/mtd/spi/spi_flash_ids.c for the list of supported chips. 10*4882a593Smuzhiyun- reg : Chip-Select number 11*4882a593Smuzhiyun- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at 12*4882a593Smuzhiyun 13*4882a593SmuzhiyunOptional properties: 14*4882a593Smuzhiyun - memory-map : Address and size of the flash, if memory mapped. This may 15*4882a593Smuzhiyun apply to Intel chipsets, which tend to memory-map flash. 16*4882a593Smuzhiyun 17*4882a593SmuzhiyunExample: 18*4882a593Smuzhiyun 19*4882a593Smuzhiyun flash: m25p80@0 { 20*4882a593Smuzhiyun #address-cells = <1>; 21*4882a593Smuzhiyun #size-cells = <1>; 22*4882a593Smuzhiyun compatible = "spansion,m25p80"; 23*4882a593Smuzhiyun reg = <0>; 24*4882a593Smuzhiyun spi-max-frequency = <40000000>; 25*4882a593Smuzhiyun }; 26
