If a GPIO bank has greater than 16 pins, PAD_DS_REG is split into two
or more registers. However, when register and bit were calculated, the
first register defined in the bank was used, and the bit was calculated
based on the first pin. This causes problems in setting the driving
strength.
The following method was used to solve this problem:
A bit is calculated first using predefined strides. Then, If the bit is
32 or more, the register is changed by the quotient of the bit divided
by 32. And the bit is set to the remainder.

This patch causes pcs_parse_pinconf() to return -ENOTSUPP when no
pinctrl_map is added. The current behavior is to return 0 when
!PCS_HAS_PINCONF or !nconfs. Thus pcs_parse_one_pinctrl_entry()
incorrectly assumes that a map was added and sets num_maps = 2.
Analysis:
=========
The function pcs_parse_one_pinctrl_entry() calls pcs_parse_pinconf()
if PCS_HAS_PINCONF is enabled. The function pcs_parse_pinconf()
returns 0 to indicate there was no error and num_maps is then set to 2:
980 static int pcs_parse_one_pinctrl_entry(struct pcs_device *pcs,
981 struct device_node *np,
982 struct pinctrl_map **map,
983 unsigned *num_maps,
984 const char **pgnames)
985 {
<snip>
1053 (*map)->type = PIN_MAP_TYPE_MUX_GROUP;
1054 (*map)->data.mux.group = np->name;
1055 (*map)->data.mux.function = np->name;
1056
1057 if (PCS_HAS_PINCONF && function) {
1058 res = pcs_parse_pinconf(pcs, np, function, map);
1059 if (res)
1060 goto free_pingroups;
1061 *num_maps = 2;
1062 } else {
1063 *num_maps = 1;
1064 }
However, pcs_parse_pinconf() will also return 0 if !PCS_HAS_PINCONF or
!nconfs. I believe these conditions should indicate that no map was
added by returning -ENOTSUPP. Otherwise pcs_parse_one_pinctrl_entry()
will set num_maps = 2 even though no maps were successfully added, as
it does not reach "m++" on line 940:
895 static int pcs_parse_pinconf(struct pcs_device *pcs, struct device_node *np,
896 struct pcs_function *func,
897 struct pinctrl_map **map)
898
899 {
900 struct pinctrl_map *m = *map;
<snip>
917 /* If pinconf isn't supported, don't parse properties in below. */
918 if (!PCS_HAS_PINCONF)
919 return 0;
920
921 /* cacluate how much properties are supported in current node */
922 for (i = 0; i < ARRAY_SIZE(prop2); i++) {
923 if (of_find_property(np, prop2[i].name, NULL))
924 nconfs++;
925 }
926 for (i = 0; i < ARRAY_SIZE(prop4); i++) {
927 if (of_find_property(np, prop4[i].name, NULL))
928 nconfs++;
929 }
930 if (!nconfs)
919 return 0;
932
933 func->conf = devm_kcalloc(pcs->dev,
934 nconfs, sizeof(struct pcs_conf_vals),
935 GFP_KERNEL);
936 if (!func->conf)
937 return -ENOMEM;
938 func->nconfs = nconfs;
939 conf = &(func->conf[0]);
940 m++;
This situtation will cause a boot failure [0] on the BeagleBone Black
(AM3358) when am33xx_pinmux node in arch/arm/boot/dts/am33xx-l4.dtsi
has compatible = "pinconf-single" instead of "pinctrl-single".
The patch fixes this issue by returning -ENOSUPP when !PCS_HAS_PINCONF
or !nconfs, so that pcs_parse_one_pinctrl_entry() will know that no
map was added.
Logic is also added to pcs_parse_one_pinctrl_entry() to distinguish
between -ENOSUPP and other errors. In the case of -ENOSUPP, num_maps
is set to 1 as it is valid for pinconf to be enabled and a given pin
group to not any pinconf properties.

This patch removes the instance number from the "miim", "reco_clk" and
"sfp" pin function.
The change needed is to prepare the driver for adding new platforms
with more of these instances. The instance number is also redundant,
as this is implicit for each pin.

This fixes the situation where the GPIO controller is not
used as an interrupt controller as well.
Previously, the driver would silently fail to register even the
GPIO's. With this change, the driver will only register as an
interrupt controller if a parent interrupt is provided.

Currently the AMD pin controller driver supports ACPI platform only.
Make the PINCTRL_AMD config symbol depend on ACPI, to avoid asking the
user about it when configuring a kernel without ACPI support.

The Equilibrium pin controller is only present on Intel Lightning
Mountain SoCs. Add an architecture dependency to the
PINCTRL_EQUILIBRIUM config symbol, to avoid asking the user about it
when configuring a kernel for a non-x86 architecture.

Renesas RZ/G1H (R8A7742) is pin compatible with R-Car H2 (R8A7790),
however it doesn't have several automotive specific peripherals. Add
automotive-specific pin groups/functions along with common pin
groups/functions for supporting both r8a7790 and r8a7742 SoC.

In function rockchip_dt_node_to_map, a new_map variable is
allocated by:
new_map = devm_kcalloc(pctldev->dev, map_num, sizeof(*new_map),
GFP_KERNEL);
This uses devres and attaches new_map to the pinctrl driver.
This cause a leak since new_map is not released when the probed
driver is removed. Fix it by using kcalloc to allocate new_map
and free it in `rockchip_dt_free_map`
