From 43dc9f88ff4db5c932cfb35cfe4bfeff25ed60e2 Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Fri, 16 Feb 2024 14:04:43 +0000 Subject: [PATCH] ARM: dts: samsung: exynos3250: specify the SPI FIFO depth Up to now the SPI alias was used as an index into an array defined in the SPI driver to determine the SPI FIFO depth. Drop the dependency on the SPI alias and specify the SPI FIFO depth directly into the SPI node. exynos3250.dtsi defines the following aliases: spi0 = &spi_0; spi1 = &spi_1; 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 a 64 byte FIFO depth. Update device tree with these FIFO depths. No functional change expected.
