Drop the dependency on the SPI alias and specify the SPI FIFO depth directly into the SPI node. exynos5250.dtsi defines the following aliases: spi0 = &spi_0; spi1 = &spi_1; spi2 = &spi_2; spi-s3c64xx.c driver defines the following fifo_lvl_mask for the "samsung,exynos4210-spi" compatible: .fifo_lvl_mask = { 0x1ff, 0x7F, 0x7F }, Thus spi0 was considered having a 256 byte FIFO depth, and spi1 and spi2 having 64 byte FIFO depth each. Update device tree with these FIFO depths. No functional change expected.
