From b0cc1b846fcb310c0ac2f8cbeb4ed5947dc52912 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Wed, 27 Feb 2019 15:36:44 +0100 Subject: dm: spi: Read default speed and mode values from DT This patch update the behavior introduced by commit 96907c0fe50a ("dm: spi: Read default speed and mode values from DT") In case of DT boot, don't read default speed and mode for SPI from CONFIG_* but instead read from DT node. This will make sure that boards with multiple SPI/QSPI controllers can be probed at different bus frequencies and SPI modes. Remove also use in boards of the value speed=0 (no more supported) for ENV in SPI by using CONFIG_ENV_SPI_MAX_HZ=0. DT values will be always used when available (full DM support of SPI slave with available DT node) even if speed and mode are requested; for example in splash screen support (in splash_sf_read_raw) or in SPL boot (in spl_spi_load_image). The caller of spi_get_bus_and_cs() no more need to force speed=0. But the current behavior don't change if the SPI slave is not present (device with generic driver is created automatically) or if platdata is used (CONFIG_OF_PLATDATA).
