Biju Das 41a87e789c pinctrl: renesas: rzg2l: remove unnecessary check from rzg2l_dt_node_to_map()
This patch removes the unnecessary check from rzg2l_dt_node_to_map()
as the ret value is already negative.

Do not imply that some of the generic headers may be always included.
Instead, include explicitly what we are direct user of.

Lad Prabhakar db2e5f21a4 pinctrl: renesas: pinctrl-rzg2l: Add IRQ domain to handle GPIO interrupt
Add IRQ domain to RZ/G2L pinctrl driver to handle GPIO interrupt.

GPIO0-GPIO122 pins can be used as IRQ lines but only 32 pins can be
used as IRQ lines at a given time. Selection of pins as IRQ lines
is handled by IA55 (which is the IRQC block) which sits in between the
GPIO and GIC.

Biju Das bfc69bdbaa pinctrl: renesas: rzg2l: Add RZ/G2UL support
RZ/G2UL SoC has fewer pins compared to RZ/G2L and the port pin

This patch adds a new compatible to take care of these differences by

rzg2l_dedicated_pins.common.

Update rzg2l_gpio_register() to use driver data for chip->names
and check for gpio-range. This allows reusing the driver for
SoC's with different port pin definitions(eg:- RZ/G2UL SoC has
fewer ports compared to RZ/G2L and port pin definitions are
different).

supported pins.
