2020-02-07dm: irq: Add support for interrupt controller typesSimon Glass
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.

2020-02-07x86: Add a clock driver for Intel devicesSimon Glass
So far we have avoided adding a clock driver for Intel devices. But the Designware I2C driver needs a different clock (133MHz) on Intel devices than on others (166MHz). Add a simple driver that provides this information. This driver can be expanded later as needed. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2020-02-07dm: core: Add a function to find a device by drvdataSimon Glass
It is sometimes useful to find a device in a uclass using only its driver data. The driver data often indicates the 'subtype' of the device, e,g, via its compatible string. Add a function to handle this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2020-02-06video: enable VIDEO_ANSI and all VIDEO_BBP optionsAnatolij Gustschin
This partially reverts changes by commit 2cc393f32fd9 ("video: make BPP and ANSI configs optional") since it caused issues with other boards (missing LCD console output on pinebook, x86 platform or sandbox). Enable all disabled options again and opt out of not supported color depth in board defconfigs. Signed-off-by: Anatolij Gustschin <agust@denx.de> Reported-by: Vagrant Cascadian <vagrant@debian.org>
2020-02-05sandbox: Complete migration away from os_malloc()Simon Glass
Now that we can use direct access to the system malloc() in sandbox, drop the remaining uses of os_malloc(). The only one remaining now is for the RAM buffer, which we do want to be at a known address, so this is intended. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-02-05dm: core: Drop the inclusion of linux/compat.h in dm.hSimon Glass
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>
2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
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.

2020-02-05dm: core: Require users of devres to include the headerSimon Glass
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.
