| * dm: core: Drop the inclusion of linux/compat.h in dm.hSimon Glass2020-02-053-1/+4
| | | | | | | | | | | | | | Most files don't need this header and it pulls in quite of lots of stuff, malloc() in particular. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: core: Create a new header file for 'compat' featuresSimon Glass2020-02-053-71/+87
| | | | | | | | | | | | | | | | | | | | | | | | At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

| * dm: core: Require users of devres to include the headerSimon Glass2020-02-052-2/+4
| | | | | | | | | | | | | | | | | | | | At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres.

| * sound: Add a new stop_play() methodSimon Glass2020-02-051-0/+12
| | | | | | | | | | | | | | | | | | | | | | At present there is no positive indication that U-Boot has finished sending sound data. This means that it is not possible to power down an audio codec, for example. Add a new method that is called once all sound data has been sent. Add a new method for this, called when the sound_play() call is done. Signed-off-by: Simon Glass <sjg@chromium.org>

| * sandbox: Rename strdup() functionsSimon Glass2020-02-051-0/+5
| | | | | | | | | | | | | | | | | | | | These functions include calls to a memory-allocation routine and so need to use the system routine when called from a library. To preserve access to these functions for libraries that need it, such as SDL, rename these functions within U-Boot. Signed-off-by: Simon Glass <sjg@chromium.org>
| * string: Allow arch override of strndup() alsoSimon Glass2020-02-051-1/+1
| | | | | | | | | | | | | | At present architectures can override strdup() but not strndup(). Use the same option for both. Signed-off-by: Simon Glass <sjg@chromium.org>
| * sandbox: Use a prefix for all allocation functionsSimon Glass2020-02-051-2/+22
| | | | | | | | | | | | | | | | | | | | | | In order to allow use of both U-Boot's malloc() and the C library's version, set a prefix for the allocation functions so that they can co-exist. This is only done for sandbox. For other archs everything remains the same. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | When writing tests to check the output from commands it is useful to be able to check the output line by line using an assertion. Add helper macros to support this and to check that there is no unexpected trailing data. Also some commands produce a dump using print_buffer().

| | | | | | | | | | | | | | | | | | | | | | | | | | This function is actually intended to read a string rather than a property. All of its current callers use it that way. Also there is no way to return the length of the property from this function. Rename it to better indicate its purpose, using ofnode_read as the prefix since this matches most other functions.

Add a mechanism, similar to clock and reset, to read the interrupts required by a device from the device tree and to request those interrupts. U-Boot itself does not have interrupt-driven handlers, so just provide a means to read and clear an interrupt. This can be useful to handle peripherals which must use an interrupt to determine when data is available, for example. Bring over the basic binding file as well, from Linux v5.4. Note that the older binding is not supported in U-Boot; the newer 'special form' must be used. Add a simple test of the new functionality.

| * | dm: irq: Add support for interrupt controller typesSimon Glass2020-02-071-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There can be different types of interrupt controllers in a system and some drivers may need to distinguish between these. In general this can be handled using the device tree by adding the interrupt information to device nodes. However on x86 devices we have interrupt controllers which are not tied to any particular device and not really used in U-Boot. These still need to be inited, so a convenient method is to give each controller a type and allow a particular controller type to be probed. Add support for this in sandbox along with a test.
