In many instances regmap_update_bits() is used for simple bit setting
and clearing. In these cases the last argument is redundant and we can
hide it with a static inline function.
This adds three new helpers for simple bit operations: set_bits,
clear_bits and test_bits.

- Move the idt descriptor table definition to spare the extra #ifdef
s
The difference between 32 and 64 bit vs. early #PF handling is not
documented. Replace the FIXME at idt_setup_early_pf() with proper comments.

Since 8175cfbbbfcb ("x86/idt: Remove update_intr_gate()") set_intr_gate()
and idt_setup_from_table() are only called from __init functions. Mark them
as well.

Use the actual struct size to calculate the IDT table sizes instead of two
different hardcoded values.

May I suggest one more clarifying sentence to your commit log:

The function connects an IRQ domain to a gpiochip and reuses
gpiochip_to_irq() which is provided by gpiolib.
gpiochip_irqchip_* and regmap_irq partially provide the same
functionality. This function will help to connect just the
minimal functionality of the gpiochip_irqchip which is needed to

There are quite a lot simple GPIO controller which are using regmap to
access the hardware. This driver tries to be a base to unify existing
code into one place. This won't cover everything but it should be a good
starting point.
It does not implement its own irq_chip because there is already a
