Update the code to use a flexible array member instead of a pointer in
structure tb10x_pinctrl and use the struct_size() helper:
struct tb10x_pinctrl {
...
struct tb10x_of_pinfunc pinfuncs[];
};
Also, make use of the struct_size() helper instead of an open-coded
version in order to avoid any potential type mistakes.
So, replace the following form:
sizeof(struct tb10x_pinctrl) + of_get_child_count(of_node) * sizeof(struct tb10x_of_pinfunc)
with:
struct_size(state, pinfuncs, of_get_child_count(of_node))
This code was detected with the help of Coccinelle.

Add new macros for describing pins without GPIO functionality:
- NOGP_ALL() expands to a list of PIN_id values, to be used for
generating symbolic enum values,
- PINMUX_NOGP_ALL() expands to a list of sh_pfc_pin entries, to
list all pins and their capabilities.
Both macros depend on an SoC-specific CPU_ALL_NOGP() macro, to be
provided by each individual SoC pin control driver.
The new macros offer two advantages over the existing SH_PFC_PIN_NAMED()
and SH_PFC_PIN_NAMED_CFG() macros:
1. They do not rely on PIN_NUMBER() macros and physical pin numbering,
hence do not suffer from pin numbering confusion among different
SoC/SiP packages.
2. They are similar in spirit to the existing scheme for handling pins
with GPIO functionality.
Note that internal to the driver, non-GPIO pins use a sequential
numbering scheme which starts after the highest GPIO pin number in use.
This value is calculated automatically, using two new helper macros, for
systems with either 32-port bank (GP port style) or linear (PORT style)
pin space. Sample expansion:
GP_LAST = sizeof(union {
char dummy[0] __attribute__((deprecated, deprecated));
char GP_0_0[(0 * 32) + 0] __attribute__((deprecated, deprecated));
char GP_0_1[(0 * 32) + 1] __attribute__((deprecated, deprecated));
...
char GP_7_3[(7 * 32) + 3] __attribute__((deprecated, deprecated));
})

pinctrl variants that include pinctrl-paris.h (and not
pinctrl-mtk-common.h) also need to use pm_ops to setup
wake mask properly, so copy over the pm_ops from common
to paris variant.
It is not easy to merge the 2 copies (or move
mtk_eint_suspend/resume to mtk-eint.c), as we need to
dereference pctrl->eint, and struct mtk_pinctrl *pctl has a
different structure definition for v1 and v2 (which is
what paris variant uses).

Rework the BM1880 SoC pinmux handling by removing the
BM1880_PINMUX_FUNCTION_MUX define and merging it with the
BM1880_PINMUX_FUNCTION definition. Since the PWM muxing is handled by
generic pin controller in the SoC itself, there is no need to have a
dedicated code to do the muxing in PWM registers. So, lets club all
pinmux handling in the same per pin mux handling code.

GPIOs are split between several banks (A, B, ...) and each bank can have
up to 16 lines. Those GPIOs could be used as interrupt lines thanks to
exti lines. As there are only 16 exti lines, a mux is used to select which
gpio line is connected to which exti line. Mapping is done as follow:
-A0, B0, C0.. -->exti_line_0 (X0 selected by mux_0)
-A1, B1, C1.. -->exti_line_1 (X1 selected by mux_1)
...
This patch adds a protection to avoid overriding on mux_n for exti_line_n.
