2020-12-23test: spi: Add sandbox_spi_get_{speed, mode} interfaceOvidiu Panait1-0/+14
Introduce sandbox_spi_get_{speed, mode} public interface to retrieve the sandbox spi bus internal state. They are meant to be used in sandbox spi testcases. Signed-off-by: Ovidiu Panait <ovidiu.panait@windriver.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2020-12-23spi: sandbox_spi: Implement speed/mode setupOvidiu Panait1-0/+26
Implement sandbox_spi_set_{speed, mode} routines, to be able to keep track of the current bus speed/mode. This will help determine whether the values passed from dm_spi_claim_bus() are valid. Signed-off-by: Ovidiu Panait <ovidiu.panait@windriver.com>
2020-12-23sandbox: test: Add a second SPI slave on sandbox_spi busOvidiu Panait1-2/+2
Place a second spi slave on the sandbox_spi bus, to be used by the spi_claim_bus() testcase we are about to introduce. We need to make sure that jumping between slaves calling spi_claim_bus() sets the bus speed and mode appropriately. Use different max-hz and mode properties for this new slave. Also, update sandbox_spi cs_info call to allow activity on CS0/CS1 and adapt dm_test_spi_find() testcase for this new setup.

2020-12-23sandbox: spi: Drop unused sandbox_spi_parse_spec functionOvidiu Panait1-16/+0
Commit 1289e96797bf ("sandbox: spi: Drop command-line SPI option") dropped support for specifying SPI devices on the command line, removing the only user of sandbox_spi_parse_spec(). Remove the function too. Fixes: 1289e96797bf ("sandbox: spi: Drop command-line SPI option") Signed-off-by: Ovidiu Panait <ovidiu.panait@windriver.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2020-12-19dm: Avoid accessing seq directlySimon Glass1-1/+1
At present various drivers etc. access the device's 'seq' member directly. This makes it harder to change the meaning of that member. Change access to go through a function instead. The drivers/i2c/lpc32xx_i2c.c file is left unchanged for now. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-07-17dm: acpi: Enhance acpi_get_name()Simon Glass1-10/+0
For many device types it is possible to figure out the name just by looking at its uclass or parent. Add a function to handle this, since it allows us to cover the vast majority of cases automatically. However it is sometimes impossible to figure out an ACPI name for a device just by looking at its uclass. For example a touch device may have a vendor-specific name. Add a new "acpi,name" property to allow a custom name to be created. With this new feature we can drop the get_name() methods in the sandbox I2C and SPI drivers. They were only added for testing purposes. Update the tests to use the new values.

2020-07-10drivers: rename drivers to match compatible stringWalter Lozano1-2/+2
When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info. In order to make things a bit more clear, rename the drivers names. This will also help for further OF_PLATDATA improvements, such as checking for valid driver names.

2019-11-03spi: Add support for memory-mapped flashSimon Glass1-0/+11
On x86 platforms the SPI flash can be mapped into memory so that the contents can be read with normal memory accesses. Add a new SPI method to find the location of the SPI flash in memory. This differs from the existing device-tree "memory-map" mechanism in that the location can be discovered at run-time.

2019-10-24dm: spi: Change cs_info op to return -EINVAL for invalid cs numBin Meng1-1/+1
We need distinguish the following two situations in various SPI APIs: - given chip select num is invalid - given chip select num is valid, but no device is attached Currently -ENODEV is returned for both cases. For the first case, it's more reasonable to return -EINVAL instead of -ENODEV for invalid chip select numbers.
