2020-02-10regulator: fix: Move code to enable gpio regulator to pre_probe from ↵Lukasz Majewski
ofdata_to_platdata The commit e8e9715df2d4 ("regulator: fixed: Modify enable-active-high behavior") fixed the regulator driver behavior when 'enable-active-high' is defined. Unfortunately, this patch used dm_regulator_platdata()'s "boot_on" member to set GPIOD_IS_OUT_ACTIVE flag and enable the regulator. The issue here is that regulator_common_ofdata_to_platdata() is called _before_ regulator_pre_probe() function in which the 'regulator-boot-on' property is asserted. As a result the GPIOD_IS_OUT_ACTIVE flag is not set and gpio_request_by_name() called in the former function is not enabling the regulator. This is problematic for e.g. i.MX ethernet driver, which then tries to perform initialization without power (and fails). The solution here is to explicitly enable regulator in regulator_pre_probe() callback only when 'regulator-boot-on' property is present in device tree. The GPIOD_IS_OUT_ACTIVE flag is not set at all, but relevant gpio is requested.

2020-02-09gpio: Let DM_74X164 be built without CONFIG_SPL_GPIOFabio Estevam
Since commit bcee8d6764f9 ("dm: gpio: Allow control of GPIO uclass in SPL") CONFIG_DM_74X164 is no longer built for mx7dsabresd_defconfig, as this target does not use CONFIG_SPL_GPIO. Remove such dependency and let the the 74X164 GPIO driver be built again. This restores Ethernet functionality on the imx7-sdb board as the Ethernet reset PHY comes from a GPIO driven by a 74LV595PW I/O expander.

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.

2020-02-07dm: 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.

2020-02-05dm: 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
