2020-12-23test: dm: spi: Add testcase for spi_claim_bus()Ovidiu Panait1-0/+82
Add testcase for spi_claim_bus(), which checks that sandbox spi bus speed/mode settings are updated correctly when multiple slaves use the bus consecutively. The following configurations are used for the two spi slaves involved: * different max_hz / different modes * different max_hz / same modes * different modes / same max_hz asm/test.h header is added in order to be able to retrieve the current speed/mode of the sandbox spi bus, via sandbox_spi_get_{speed, mode}.

2020-12-23sandbox: test: Add a second SPI slave on sandbox_spi busOvidiu Panait1-1/+1
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.

2020-08-08dm: Rename DM test flags to make them more genericSimon Glass1-2/+2
The test flags used by driver model are currently not available to other tests. Rather than creating two sets of flags, make these flags generic by changing the DM_ prefix to UT_ and moving them to the test.h header. This will allow adding other test flags without confusion.

2020-08-04dm: core: Drop header files from dm/test.hSimon Glass1-0/+1
These header file should not be included in other header files. Remove them and add to each individual file. Add test/test.h to test/ui.h since that is a reasonable place. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-07-10drivers: rename drivers to match compatible stringWalter Lozano1-3/+3
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.

2020-06-29spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI*Lukasz Majewski1-1/+1
This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

2020-01-27test: dm: spi: Fix sandbox dm_test_spi_find()Bin Meng1-3/+3
Per sandbox_cs_info(), sandbox spi controller only supports chip select 0. Current test case tries to locate devices on chip select 1, and any call to spi_get_bus_and_cs() or spi_cs_info() with cs number 1 should not return 0. This updates the test case to handle it correctly. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Jagan Teki <jagan@amarulasolutions.com>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-04-05dm: core: Add flags parameter to device_remove()Stefan Roese1-1/+1
This patch adds the flags parameter to device_remove() and changes all calls to this function to provide the default value of DM_REMOVE_NORMAL for "normal" device removal. This is in preparation for the driver specific pre-OS (e.g. DMA cancelling) remove support.

2017-02-08dm: core: Replace of_offset with accessorSimon Glass1-1/+1

2015-01-30dm: spi: Move slave details to child platdataSimon Glass1-3/+3
At present we go through various contortions to store the SPI slave's chip select in its private data. This only exists when the slave is active so must be set up when it is probed. Until the device is probed we don't actually know what chip select it will appear on. However, now that we can support per-child platform data, we can use that instead. This allows us to set up the chip select when the child is bound, and avoid the messy contortions. Unfortunately this is a fairly large change and it seems to be difficult to break it down further.
