2020-10-29dm: Support parent devices with of-platdataSimon Glass
At present of-platdata does not provide parent information. But this is useful for I2C devices, for example, since it allows them to determine which bus they are on. Add support for setting the parent correctly, by storing the parent driver_info index in dtoc and reading this in lists_bind_drivers(). This needs multiple passes since we must process children after their parents already have been bound. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-10-29sandbox: Fix up building for of-platdataSimon Glass
There is no devicetree with of-platdata. Update a few uclasses to allow them to be built for sandbox_spl. Also drop the i2c-gpio from SPL to avoid build errors, since it does not support of-platdata. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-10-29dm: Use an allocated array for run-time device infoSimon Glass
At present we update the driver_info struct with a pointer to the device that it created (i.e. caused to be bound). This works fine when U-Boot SPL is stored in read-write memory. But on some platforms, such as Intel Apollo Lake, it is not possible to update the data memory. In any case, it is bad form to put this information in a structure that is in the data region, since it expands the size of the binary. Create a new driver_rt structure which holds runtime information about drivers. Update the code to store the device pointer in this instead. Also update the test check that this works.

2020-10-29dm: test: Add a test for of-platdata phandlesSimon Glass
We have a test in dtoc for this feature, but not one in U-Boot itself. Add a simple test that checks that the information comes through correctly. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-10-29dm: test: Add a check that all devices have a dev valueSimon Glass
With of-platdata, the driver_info struct is updated with the device pointer when it is bound. This makes it easy for a device to be found by its driver info with the device_get_by_driver_info() function. Add a test that all devices (except the root device) have such an entry. Fix a bug that the function does not set *devp to NULL on failure, which the documentation asserts. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-10-29dm: Add a C test for of-platdata propertiesSimon Glass
At present properties are tested in a roundabout way. The driver's probe() method writes out the values of the properties and the Python test checks the output from U-Boot SPL. Add a C test which checks these values more directly. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-10-29dm: test: Add a very simple of-platadata testSimon Glass
At present we have a pytest that covers of-platadata. Add a very simple unit test that just checks that a device can be found. This shows the ability to write these tests in C. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-10-29dm: test: Add a way to run SPL testsSimon Glass
Add a -u flag for U-Boot SPL which requests that unit tests be run. To make this work, export dm_test_main() and update it to skip test features that are not used with of-platdata. To run the tests: $ spl/u-boot-spl -u U-Boot SPL 2020.10-rc5 (Oct 01 2020 - 07:35:39 -0600) Running 0 driver model tests Failures: 0 At present there are no SPL unit tests. Note that there is one wrinkle with these tests. SPL has limited memory available for allocation. Also malloc_simple does not free memory (free() is a nop) and running tests repeatedly causes driver-model to reinit multiple times and allocate memory. Therefore it is not possible to run more than a few tests at a time. One solution is to increase the amount of malloc space in sandbox_spl. This is not a problem for pytest, since it runs each test individually, so for now this is left as is. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-10-29dm: test: Update the test runner to support of-platdataSimon Glass
At present DM tests assume that a devicetree is available. This is not the case with of-platadata. Update the code to add this condition. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-10-29dtoc: Fix widening of int to bytesSimon Glass
At present an integer is converted to bytes incorrectly. The whole 32-bit integer is inserted as the first element of the byte array, and the other three bytes are skipped. This was not noticed because the unit test did not check it, and the functional test was checking for wrong values. Update the code to handle this as a special case. Add one more test to cover all code paths. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-10-29dm: core: Allow dm_warn() to be used in SPLSimon Glass
At present this option is disabled in SPL, meaning that warnings are not displayed. It is sometimes useful to see warnings in SPL for debugging purposes. Add a new Kconfig option to permit this. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-10-29dtoc: Order the structures internally by nameSimon Glass
At present the structures are written in name order, but parents have to be written before their children, so the file does not end up being in order. The order of nodes in _valid_nodes matches the order of the devicetree. Update the code so that _valid_nodes is in sorted order, by C name of the structure. This allows us to assign a sequential ordering to each U_BOOT_DEVICE() declaration. U-Boot's linker lists are also ordered alphabetically, which means that the order in the driver_info list will match the order used by dtoc. This defines an index ('idx') for the U_BOOT_DEVICE declarations. They appear in alphabetical order, numbered from 0 in _valid_nodes and in the driver_info linker list. Add a comment against each declaration, showing the idx value. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-10-29sandbox: Drop ad-hoc device declarations in SPLSimon Glass
Since sandbox's SPL is build with of-platadata, we should not use U_BOOT_DEVICE() declarations as well. Drop them. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-10-29dm: test: Disable some tests that should not run in SPLSimon Glass
Tests are easier to run in U-Boot proper. Running them in SPL does not add test coverage in most cases. Also some tests use features that are not available in SPL. Update the build rules to disable these tests in SPL. We still need test-main to be able to actually run SPL tests. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-10-29dm: test: Make use of CONFIG_UNIT_TESTSimon Glass
At present we always include test/dm from the main Makefile. We have a CONFIG_UNIT_TEST that should control whether the test/ directory is built, so rely on that instead. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-10-29dm: test: Update Makefile conditionsSimon Glass
At present most of the tests in test/Makefile are dependent on CONFIG_SANDBOX. But this is not ideal since they rely on commands being available and SPL does not support commands. Use CONFIG_COMMAND instead. This has the dual purpose of allowing these tests to be used on other boards and allowing SPL to skip them. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-10-28cmd: Add a mux commandPratyush Yadav
This command lets the user list, select, and deselect mux controllers introduced with the mux framework on the fly. It has 3 subcommands: list, select, and deselect. List: Lists all the mux present on the system. The muxes are listed for each chip. The chip is identified by its device name. Each chip can have a number of mux controllers. Each is listed in sequence and is assigned a sequential ID based on its position in the mux chip. It lists details like ID, whether the mux is currently selected or not, the current state, the idle state, and the number of states. A sample output would look something like: => mux list a-mux-controller: ID Selected Current State Idle State Num States 0 no unknown as-is 0x4 1 no 0x2 0x2 0x10 2 no 0x73 0x73 0x100 another-mux-controller: ID Selected Current State Idle State Num States 0 no 0x1 0x1 0x4 1 no 0x2 0x2 0x4 Select: Selects a given mux and puts it in the specified state. This subcommand takes 3 arguments: mux chip, mux ID, state to set the mux in. The arguments mux chip and mux ID are used to identify which mux needs to be selected, and then it is selected to the given state. The mux needs to be deselected before it can be selected again in another state. The state should be a hexadecimal number. For example: => mux list a-mux-controller: ID Selected Current State Idle State Num States 0 no 0x1 0x1 0x4 1 no 0x1 0x1 0x4 => mux select a-mux-controller 0 0x3 => mux list a-mux-controller: ID Selected Current State Idle State Num States 0 yes 0x3 0x1 0x4 1 no 0x1 0x1 0x4 Deselect: Deselects a given mux and puts it in its idle state. This subcommand takes 2 arguments: the mux chip and mux ID to identify which mux needs to be deselected. So in the above example, we can deselect mux 0 using: => mux deselect a-mux-controller 0 => mux list a-mux-controller: ID Selected Current State Idle State Num States 0 no 0x1 0x1 0x4 1 no 0x1 0x1 0x4 Signed-off-by: Pratyush Yadav <p.yadav@ti.com> Reviewed-by: Simon Glass <sjg@chromium.org>
