2020-02-07x86: Add support for ACPI general-purpose eventsSimon Glass
ACPI GPEs are used to signal interrupts from peripherals that are accessed via ACPI. In U-Boot these are modelled as interrupts using a separate interrupt controller. Configuration is via the device tree. Add a simple driver for this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2020-02-07dm: irq: Add support for requesting interruptsSimon Glass
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.

2020-01-07dfu: Add optional timeout parameterAndy Shevchenko
When the `dfu` command is called from the U-Boot environment, it now accepts an optional parameter that specifies a timeout (in seconds). If a DFU connection is not made within that time the `dfu` command exits (as it would if Ctrl+C was pressed). If the timeout is left empty or being zero the `dfu` command behaves as it does now. This is useful for allowing U-Boot to check to see if anything wants to upload new firmware before continuing to boot. The patch is based on the commit https://github.com/01org/edison-u-boot/commit/5e966ccc3c65c18c9783741fa04e0c45e021780c by Sebastien Colleur, which has been heavily reworked due to U-Boot changes in the past.

At present PCI auto-configuration happens in U-Boot both before and after relocation. This is a waste of time and may mess up static addresses used in board_init_f(). Adjust the code to supporting doing auto-configuration once, after relocation, under control of a device-tree property. This is needed for Apollo Lake for debugging the silicon-init code. Once the UART is moved to a different MMIO address the debug UART does not work and any debug output in Apollo Lake's arch_fsp_init_r() causes a hang.

Based on commit 980066e6d964 ("dt-bindings: phy: dp83867: Add documentation for disabling clock output") of mainline linux kernel. The clock output is generally only used for testing and development and not used to daisy-chain PHYs. It's just a source of RF noise afterward. Add a mux value for "off". I've added it as another enumeration to the output property. In the actual PHY, the mux and the output enable are independently controllable. However, it doesn't seem useful to be able to describe the mux setting when the output is disabled. Document that PHY's default setting will be left as is if the property is omitted.
