2020-04-16gpio: update dir_flags managementPatrick Delaunay
Update the flag management in GPIO uclass: the desc->flags is always combined with the requested flags and the GPIO descriptor is updated for further call. Add a function dm_gpio_get_dir_flags to get dynamically the current dir_flags (configuration and value). This patch prepare introduction of the dir flags support with new ops.

2020-04-16dm: core: Read parent ofdata before childrenSimon Glass
At present a device can read its ofdata before its parent has done the same. This can cause problems in the case where the parent has a 'ranges' property, thus affecting the operation of dev_read_addr(), for example. We already probe parent devices before children so it does not seem to be a large step to do the same with ofdata. Make the change and update the documentation in this area.

2020-04-16dm: core: Add basic ACPI supportSimon Glass
ACPI (Advanced Configuration and Power Interface) is a standard for specifying information about a platform. It is a little like device tree but the bindings are part of the specification and it supports an interpreted bytecode language. Driver model does not use ACPI for U-Boot's configuration, but it is convenient to have it support generation of ACPI tables for passing to Linux, etc. As a starting point, add an optional set of ACPI operations to each device. Initially only a single operation is available, to obtain the ACPI name for the device. More operations are added later. Enable ACPI for sandbox to ensure build coverage and so that we can add tests.

Some watchdog devices, e.g. external gpio-triggered ones, must be reset more often than once per second, which means that the current rate-limiting logic in watchdog_reset() fails to keep the board alive. gpio-wdt.txt in the linux source tree defines a "hw_margin_ms" property used to specifiy the maximum time allowed between resetting the device. Allow any watchdog device to specify such a property, and then use a reset period of one quarter of that. We keep the current default of resetting once every 1000ms.
