On lan966x platform when the switch gets reseted then also the sgpio
gets reseted. The fix for this is to extend also the sgpio driver to
call the reset driver which will be reseted only once by the first
driver that is probed.

spmi-mpp did not have any irqchip support so consumers of this in
device tree would need to call gpio[d]_to_irq() in order to get the
proper IRQ on the underlying PMIC. IRQ chips in device tree should be

The probing of this driver calls platform_irq_count, which will
setup all of the IRQs that are configured in device tree. In
preparation for converting this driver to be a hierarchical IRQ
chip, hardcode the IRQ count based on the hardware type so that all
the IRQs are not configured immediately and are configured on an
as-needed basis later in the boot process.

This change will also allow for the removal of the interrupts property
later in this patch series once the hierarchical IRQ chip support is in.

This patch also removes the generic qcom,spmi-mpp OF match since we
don't know the number of pins. All of the existing upstream bindings
already include the more-specific binding.

If some bits in a pin Pull-Up control register (PUPR) control pin
pull-down instead of pin pull-up, there are two pinmux_bias_reg entries:
a first one with the puen field filled in, listing pins with pull-up
functionality, and a second one with the pud field filled in, listing
pins with pull-down functionality.  On encountering the second entry,
where puen is NULL, the for-loop terminates early, causing the remaining
bias registers not to be checked.  In addition, sh_pfc_check_bias_reg()
does not handle such entries.

Fix this by treating pinmux_bias_reg.puen and pinmux_bias_reg.pud the
same.

a first one with the puen field filled in, listing pins with pull-up
functionality, and a second one with the pud field filled in, listing

where puen is NULL, the for-loop terminates early, causing the remaining
bias registers not to be saved/restored during PSCI system suspend.
Fortunately this does not trigger on any supported system yet, as PSCI
is only used on R-Car Gen3 and RZ/G2 systems, which all have separate
pin Pull-Enable (PUEN) and pin Pull-Up/Down control (PUD) registers.

Avoid this ever becoming a problem by treating pinmux_bias_reg.puen and
pinmux_bias_reg.pud the same.  Note that a register controlling both
pull-up and pull-down pins would be saved and restored twice, which is
harmless.

Currently, if the GPIO is configured as output in the bootloader
and user changes the mode to input in HLOS, it would end up
getting configured as input/output. Functionally, this is fine;
however, there may be some requirements where the output needs
to be disabled so that it can be used only for input.
