[ Upstream commit 63c3212e7a37d68c89a13bdaebce869f4e064e67 ]
Per the datasheet the i2c functions use MPP_Sel=0x1. They are documented
as using MPP_Sel=0x4 as well but mixing 0x1 and 0x4 is clearly wrong. On
the board tested 0x4 resulted in a non-functioning i2c bus so stick with
0x1 which works.Fixes: d7ae8f8dee7f ("pinctrl: mvebu: pinctrl driver for 98DX3236 SoC")

commit 84e7a946da71f678affacea301f6d5cb4d9784e8 upstream.
The PAT1 register contains information about the IRQ type (edge/level)
for input GPIOs with IRQ enabled, and the direction for non-IRQ GPIOs.
So it makes sense to read it only if the GPIO has no interrupt
configured, otherwise input GPIOs configured for level IRQs are
misdetected as output GPIOs.Fixes: ebd6651418b6 ("pinctrl: ingenic: Implement .get_direction for GPIO chips")

commit 1c95348ba327fe8621d3680890c2341523d3524a upstream.
Ingenic SoCs don't natively support registering an interrupt for both
rising and falling edges. This has to be emulated in software.Until now, this was emulated by switching back and forth between
IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING according to the level of
the GPIO. While this worked most of the time, when used with GPIOs that
need debouncing, some events would be lost. For instance, between the
time a falling-edge interrupt happens and the interrupt handler
configures the hardware for rising-edge, the level of the pin may have
already risen, and the rising-edge event is lost.To address that issue, instead of switching back and forth between
IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING, we now switch back and
forth between IRQ_TYPE_LEVEL_LOW and IRQ_TYPE_LEVEL_HIGH. Since we
always switch in the interrupt handler, they actually permit to detect
level changes. In the example above, if the pin level rises before
switching the IRQ type from IRQ_TYPE_LEVEL_LOW to IRQ_TYPE_LEVEL_HIGH,
a new interrupt will raise as soon as the handler exits, and the
rising-edge event will be properly detected.Fixes: e72394e2ea19 ("pinctrl: ingenic: Merge GPIO functionality")

[ Upstream commit f46fe79ff1b65692a65266a5bec6dbe2bf7fc70f ]
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 {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;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))

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.[0] https://lore.kernel.org/linux-omap/20200529175544.GA3766151@x1/

commit f354157a7d184db430c1a564c506434e33b1bec5 upstream.
Currently, for EINT_TYPE GPIOs, the CON and FLTCON registers
are saved and restored over a suspend/resume cycle. However, the
EINT_MASK registers are not.On S5PV210 at the very least, these registers are not retained over
suspend, leading to the interrupts remaining masked upon resume and
therefore no interrupts being triggered for the device. There should
be no effect on any SoCs that do retain these registers as theoretically
we would just be re-writing what was already there.Fixes: 7ccbc60cd9c2 ("pinctrl: exynos: Handle suspend/resume of GPIO EINT registers")

The imx SC api strongly assumes that messages are composed out of
4-bytes words but some of our message structs have sizeof "6" and "7".This produces many oopses with CONFIG_KASAN=y:
BUG: KASAN: stack-out-of-bounds in imx_mu_send_data+0x108/0x1f0
It shouldn't cause an issues in normal use because these structs are
always allocated on the stack.Also upstream: https://patchwork.kernel.org/patch/11376909/

[ Upstream commit 02aeb2f21530c98fc3ca51028eda742a3fafbd9f ]
pinmux_func_gpios[] contains a hole due to the missing function GPIO
definition for the "CTX0&CTX1" signal, which is the logical "AND" of the
first two CAN outputs.A closer look reveals other issues:
- Some functionality is available on alternative pins, but the
PINMUX_DATA() entries is using the wrong marks,
- Several configurations are missing.Fix this by:
- Renaming CTX0CTX1CTX2_MARK, CRX0CRX1_PJ22_MARK, and
CRX0CRX1CRX2_PJ20_MARK to CTX0_CTX1_CTX2_MARK, CRX0_CRX1_PJ22_MARK,
resp. CRX0_CRX1_CRX2_PJ20_MARK for consistency with the
corresponding enum IDs,
- Adding all missing enum IDs and marks,
- Use the right (*_PJ2x) variants for alternative pins,
- Adding all missing configurations to pinmux_data[],
- Adding all missing function GPIO definitions to pinmux_func_gpios[].See SH7268 Group, SH7269 Group User’s Manual: Hardware, Rev. 2.00:

[ Upstream commit a23680594da7a9e2696dbcf4f023e9273e2fa40b ]
Suspending Goodix touchscreens requires changing the interrupt pin to
output before sending them a power-down command. Followed by wiggling
the interrupt pin to wake the device up, after which it is put back
in input mode.On Bay Trail devices with a Goodix touchscreen direct-irq mode is used
in combination with listing the pin as a normal GpioIo resource.This works fine, until the goodix driver gets rmmod-ed and then insmod-ed
again. In this case byt_gpio_disable_free() calls
byt_gpio_clear_triggering() which clears the IRQ flags and after that the
(direct) IRQ no longer triggers.This commit fixes this by adding a check for the BYT_DIRECT_IRQ_EN flag
to byt_gpio_clear_triggering().Note that byt_gpio_clear_triggering() only gets called from
byt_gpio_disable_free() for direct-irq enabled pins, as these are excluded
from the irq_valid mask by byt_init_irq_valid_mask().Signed-off-by: Hans de Goede

pinmux_func_gpios[] contains a hole due to the missing function GPIO
definition for the "CTX0&CTX1" signal, which is the logical "AND" of the
two CAN outputs.Fix this by:
- Renaming CRX0_CRX1_MARK to CTX0_CTX1_MARK, as PJ2MD[2:0]=010
configures the combined "CTX0&CTX1" output signal,
- Renaming CRX0X1_MARK to CRX0_CRX1_MARK, as PJ3MD[1:0]=10 configures
the shared "CRX0/CRX1" input signal, which is fed to both CAN
inputs,
- Adding the missing function GPIO definition for "CTX0&CTX1" to
pinmux_func_gpios[],
- Moving all CAN enums next to each other.See SH7262 Group, SH7264 Group User's Manual: Hardware, Rev. 4.00:

[6] Section 32.2.30 (3) Port J Control Register 0 (PJCR0).Note that the last 2 disagree about PJ2MD[2:0], which is probably the
root cause of this bug. But considering [4], "CTx0&CTx1" in [5] must
be correct, and "CRx0&CRx1" in [6] must be wrong.Signed-off-by: Geert Uytterhoeven

The FN_SDSELF_B and FN_SD1_CLK_B enum IDs are used twice, which means
one set of users must be wrong. Replace them by the correct enum IDs.Fixes: 87f8c988636db0d4 ("sh-pfc: Add r8a7778 pinmux support")

commit a34cd9dfd03fa9ec380405969f1d638bc63b8d63 upstream.
R-Car Gen3 Hardware Manual Errata for Rev. 2.00 of October 24, 2019
changed the configuration bits for drive and bias control for the
DU_DOTCLKIN3 pin on R-Car M3-N, to match the same pin on R-Car H3.
Update the driver to reflect this.After this, the handling of drive and bias control for the various
DU_DOTCLKINx pins is consistent across all of the R-Car H3, M3-W,
M3-W+, and M3-N SoCs.Fixes: 86c045c2e4201e94 ("pinctrl: sh-pfc: r8a77965: Replace DU_DOTCLKIN2 by DU_DOTCLKIN3")
