spi: spi_flash_probe_bus_cs() rely on DT for spi speed and mode

2022-05-23T13:33:10Z

Now, spi_flash_probe_bus_cs() relies on DT for spi speed and mode and logically calls spi_get_bus_and_cs(). In case spi mode and speed are not read from DT, make usage of spi_flash_probe() instead. To sum-up: - Previous call tree was: spi_flash_probe() -> spi_flash_probe_bus_cs() -> spi_get_bus_and_cs() - Current call tree is: spi_flash_probe() -> _spi_get_bus_and_cs() spi_flash_probe_bus_cs() -> spi_get_bus_and_cs() This patch impacts the following : - cmd/sf.c: if spi mode and/or speed is passed in argument of do_spi_flash_probe(), call spi_flash_probe() otherwise call spi_flash_probe_bus_cs(). - drivers/net/fm/fm.c: as by default spi speed and mode was set to 0 and a comment indicates that speed and mode are read from DT, use spi_flash_probe_bus_cs(). - drivers/net/pfe_eth/pfe_firmware.c: spi speed and mode are not read from DT by all platforms using this driver, so keep legacy and replace spi_flash_probe_bus_cs() by spi_flash_probe(); - drivers/net/sni_netsec.c : spi speed and mode are not read from DT, so replace spi_flash_probe_bus_cs() by spi_flash_probe(). - drivers/usb/gadget/max3420_udc.c: Can't find any platform which make usage of this driver, nevertheless, keep legacy and replace spi_get_bus_and_cs() by _spi_get_bus_and_cs(). - env/sf.c: a comment indicates that speed and mode are read from DT. So use spi_flash_probe_bus_cs().

spi: spi-uclass: Add new spi_get_bus_and_cs() implementation

2022-05-23T13:33:10Z

Move legacy spi_get_bus_and_cs() code to _spi_get_bus_and_cs(). Add new spi_get_bus_and_cs() implementation which rely on DT for speed and mode and don't need any drv_name nor dev_name parameters. This will prepare the ground for next patch. Update all callers to use _spi_get_bus_and_cs() to keep the same behavior.
