10b304a24SSimon Glass* MTD SPI driver for serial flash chips 20b304a24SSimon Glass 30b304a24SSimon GlassRequired properties: 40b304a24SSimon Glass- #address-cells, #size-cells : Must be present if the device has sub-nodes 50b304a24SSimon Glass representing partitions. 60b304a24SSimon Glass- compatible : Should be the manufacturer and the name of the chip. Bear in 70b304a24SSimon Glass mind that the DT binding is not U-Boot-only, but in case of 80b304a24SSimon Glass U-Boot, see spi_flash_params_table table in 9*6645fd2cSJagan Teki drivers/mtd/spi/spi_flash_ids.c for the list of supported chips. 100b304a24SSimon Glass- reg : Chip-Select number 110b304a24SSimon Glass- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at 120b304a24SSimon Glass 130b304a24SSimon GlassOptional properties: 140b304a24SSimon Glass - memory-map : Address and size of the flash, if memory mapped. This may 150b304a24SSimon Glass apply to Intel chipsets, which tend to memory-map flash. 160b304a24SSimon Glass 170b304a24SSimon GlassExample: 180b304a24SSimon Glass 190b304a24SSimon Glass flash: m25p80@0 { 200b304a24SSimon Glass #address-cells = <1>; 210b304a24SSimon Glass #size-cells = <1>; 220b304a24SSimon Glass compatible = "spansion,m25p80"; 230b304a24SSimon Glass reg = <0>; 240b304a24SSimon Glass spi-max-frequency = <40000000>; 250b304a24SSimon Glass }; 26
