This patch series adds GPIO drivers, DT documentation and DT nodes for
HiFive Unleashed board. The gpio patches are mostly based on Wesley's patch=
.
The patchset also adds hierarchy irq domain support as it is required by th=
is
gpio driver.

This patchset is based on Linux 5.4-rc6 and tested on HiFive Unleashed boar=
d

Incorporated below changes as suggested by Linus Walleij on RFC version of =
this
patchset[0]
- Dropped PWM patches as they are already merged.
- Include "GPIO_GENERIC" and "REGMAP_MMIO" in Kconfig select option
- Remove unwanted inclusion of header files
- Use regmap MMIO instead of customised sifive_assign_bit()
- Use GPIOLIB_GENERIC and bgpio_init() to set up the accessors
- Use hierarchical irqdomain
