dma-mapping: add for all architectures

To avoid "asm/dma-mapping.h: No such file or directory" error, we need something. Signed-off-by: Masahiro Yamada

dm: irq: Add support for requesting interrupts

2020-02-07T14:46:32Z

At present driver model supports the IRQ uclass but there is no way to request a particular interrupt for a driver. 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. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

dm: irq: Add support for interrupt controller types

2020-02-07T14:44:59Z

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.

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46Z

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.

sandbox: Support changing the LCD colour depth

2020-02-06T02:33:46Z

Add a new device-tree property to control the colour depth. At present we support 16bpp and 32bpp. While we are here, update the code to use livetree. Signed-off-by: Simon Glass Reviewed-by: Anatolij Gustschin

sandbox: sdl: Add an option to double the screen size

2020-02-06T02:33:46Z

On high-DPI displays U-Boot's LCD window can look very small. Add a -K flag to expand it to make things easier to read, while still using the existing resolution internally. Signed-off-by: Simon Glass Reviewed-by: Anatolij Gustschin

sandbox: sdl: Move to use SDL2

2020-02-06T02:33:46Z

Sandbox currently uses SDL1.2. SDL2 has been around for quite a while and is widely supported. It has a number of useful features. It seems appropriate to move sandbox over. Update the code to use SDL2 instead of SDL1.2. Signed-off-by: Simon Glass

sandbox: sdl: Support waiting for audio to complete

2020-02-06T02:33:46Z

At present when audio stops, any in-progress output is cut off. Fix this by waiting for output to finish. Also use booleans for the boolean variables. Signed-off-by: Simon Glass

sandbox: sdl: Improve error handling

2020-02-06T02:33:46Z

A few errors are not checked. Fix these and use my preferred spelling for init. Signed-off-by: Simon Glass
