b45eb4084b pinctrl: samsung: Remove legacy API for handling external wakeup interrupts mask
Remove the legacy, ugly API of exposing the static value of external
wakeup interrupts mask, because all arch-machine users where converted
to use generic implementation from pinctrl driver.

b6e5531c0f pinctrl: bcm2835: Direct GPIO config changes to generic pinctrl
In order to support GPIO config changes direct these to the generic pinctrl.
This also requires an adjust of the return code for unsupported parameter

at91_pinctrl_mux_ops::set_drivestrength and

ff656e47a9 Pinctrl: Ingenic: Fix bugs caused by differences between JZ4770 and JZ4780.
Delete uart4 and i2c3/4 from JZ4770:
According to the datasheet, only JZ4780 have uart4 and i2c3/4. So we
remove it from the JZ4770 code and add a section corresponding the JZ4780.

Fix bugs in i2c0/1:
The pin number was wrong in the original code.

Fix bugs in uart2:
JZ4770 and JZ4780 have different uart2 pins. So the original section JZ4770
has been modified and the corresponding section of JZ4780 has been added.

Fix bugs in mmc0:
JZ4770 and JZ4780 assigned different pins to mmc0's 4~7 data lines. So the
original section JZ4770 has been modified and the corresponding section of
JZ4780 has been added.

Fix bugs in mmc1:
JZ4770's mmc1 has 8bit mode, while JZ4780 doesn't. So the original
section JZ4770 has been modified and the corresponding section of
JZ4780 has been added.

Fix bugs in nemc:
JZ4770's nemc has 16bit mode, while JZ4780 doesn't. So the original section
JZ4770 has been modified and the corresponding section of JZ4780 has been
added. And add missing cs2~5 groups for JZ4770 and JZ4780.

Fix bugs in cim:
JZ4770's cim has 12bit mode, while JZ4780 doesn't. So the original
section JZ4770 has been modified and the corresponding section of
JZ4780 has been added.

Fix bugs in lcd:
Both JZ4770 and JZ4780 lcd should be 24bit instead of 32bit.

e73339037f pinctrl: remove unused 'pinconf-config' debugfs interface
The main goal of the change is to remove .pin_config_dbg_parse_modify
callback before a driver with its support appears. So far the in-kernel
interface did not attract any users since its introduction 5 years ago.

Originally .pin_config_dbg_parse_modify callback and the associated
'pinconf-config' debugfs file were introduced in commit f07512e615
("pinctrl/pinconfig: add debug interface"), a short description of
'pinconf-config' usage for debugging can be expressed this way:

Write to 'pinconf-config' (see pinconf_dbg_config_write() function):

% echo -n modify $map_type $device_name $state_name $pin_name $config > \
	/sys/kernel/debug/pinctrl/$pinctrl/pinconf-config

It supposes to update a global (therefore single!) 'pinconf_dbg_conf'
variable with an alternative setting, the arguments should match
an existing pinconf device and some registered pinctrl mapping 'map':

* $map_type is either 'config_pin' or 'config_group', it should match
  'map->type' value of PIN_MAP_TYPE_CONFIGS_PIN or
   PIN_MAP_TYPE_CONFIGS_GROUP accordingly,
* $device_name should match 'map->dev_name' string value,
* $state_name should match 'map->name' string value,
* $pin_name should match 'map->data.configs.group_or_pin' string value,

If all above has matched, then $config is a new value to be set by calling
pinconfops->pin_config_dbg_parse_modify(pctldev, config, matched_config).

After a successful write into 'pinconf-config' a user can read the file
to get information about that single modified pin configuration.

The fact is .pin_config_dbg_parse_modify callback has never been defined
in 'struct pinconf_ops' of any pinconf driver, thus an actual modification
of a pin or group state on any present pinconf controller does not happen,
and it declares that all related code is no more than dead code.

I discovered the issue while attempting to add .pin_config_dbg_parse_modify
support in some drivers and found that too short 'MAX_NAME_LEN' set by

  drivers/pinctrl/pinconf.c:372:#define MAX_NAME_LEN 15

is practically insufficient to store a regular pinctrl device name,
which are like 'e6060000.pin-controller-sh-pfc' or pin names like
'MX6QDL_PAD_ENET_REF_CLK', thus it is another indicator that the code
is barely usable, insufficiently tested and unprepossessing.

Of course it might be possible to increase MAX_NAME_LEN, and then add
.pin_config_dbg_parse_modify callbacks to the drivers, but the whole
idea of such a limited debug option looks inviable. A more flexible
way to functionally substitute the original approach is to implicitly
or explicitly use pinctrl_select_state() function whenever needed.

ca69e2d165 qcom: spmi-gpio: add support for hierarchical IRQ chip
spmi-gpio did not have any irqchip support so consumers of this in
device tree would need to call gpio[d]_to_irq() in order to get the
proper IRQ on the underlying PMIC. IRQ chips in device tree should
be usable from the start without the consumer having to make an
additional call to get the proper IRQ on the parent. This patch adds
hierarchical IRQ chip support to the spmi-gpio code to correct this
issue.

Driver was tested using the volume buttons (via gpio-keys) on the LG
Nexus 5 (hammerhead) phone with the following two configurations.

volume-up {
        interrupts-extended = <&pm8941_gpios 2 IRQ_TYPE_EDGE_BOTH>;
        ...
};

volume-up {
        gpios = <&pm8941_gpios 2 GPIO_ACTIVE_LOW>;
        ...
};

Both configurations now show that spmi-gpio is the IRQ domain and that
the IRQ is setup in a hierarchy.

10098709b4 pinctrl: sunxi: Correct number of IRQ banks on H6 main pin controller
The H6 main pin controller has four banks of interrupt-triggering pins.
The driver as originally submitted only specified three, but had pin
descriptions referencing a fourth bank. This results in a out-of-bounds
access into .irq_array of struct sunxi_pinctrl. This however did not
result in a crash until v4.20, with commit a66d972465 ("devres: Align
data[] to ARCH_KMALLOC_MINALIGN"), which changed the alignment of memory
region returned by devm_kcalloc(). The increase likely moved the
out-of-bounds access into the next, unmapped page.

With KASAN on, the bug is quite clear:

e66dd48e8b pinctrl: meson: fix G12A ao pull registers base address
Since Meson G12A SoC, Introduce new ao registers AO_RTI_PULL_UP_EN_REG
and AO_GPIO_O.

These bits of controlling output level are remapped to the new register
AO_GPIO_O, and the AO_GPIO_O_EN_N support only controlling output enable.

These bits of controlling pull enable are remapped to the new register
AO_RTI_PULL_UP_EN_REG, and the AO_RTI_PULL_UP_REG support only controlling
pull type(up/down).

The new layout of ao gpio/pull registers is as follows:
- AO_GPIO_O_EN_N        [offset: 0x9 << 2]
- AO_GPIO_I             [offset: 0xa << 2]
- AO_RTI_PULL_UP_REG    [offset: 0xb << 2]
- AO_RTI_PULL_UP_EN_REG [offset: 0xc << 2]
- AO_GPIO_O             [offset: 0xd << 2]

From above, we can see ao GPIO registers region has been separated by the
ao pull registers. In order to ensure the continuity of the region on
software, the ao GPIO and ao pull registers use the same base address, but
can be identified by the offset.

19ab5ca9b7 pinctrl: mcp23s08: Allocate irq_chip dynamic
Keeping the irq_chip definition static shares it with multiple instances
of the mcp23s08 gpiochip in the system. This is bad and now we get this
warning from gpiolib core:

"detected irqchip that is shared with multiple gpiochips: please fix the
driver."

Hence, move the irq_chip definition from being driver static into the
struct mcp23s08. So a unique irq_chip is used for each gpiochip
instance.

f4f1b07469 pinctrl: armada-37xx: change suspend/resume time
Armada 3700 PCIe IP relies on the pinctrl IP managed by this
driver. For reasons related to the PCI core's organization when
suspending/resuming, PCI host controller drivers must reconfigure
their register at suspend_noirq()/resume_noirq() which happens after
suspend()/suspend_late() and before resume_early()/resume().

In the current state, after resuming from a suspend to RAM cycle the
PCIe IP is reconfigured before the pinctrl one which produces an
interrupt storm. The solution to support PCIe resume operation is to
change the "priority" of this pinctrl driver PM callbacks to
"_noirq()".

cfacef3735 pinctrl: qcom: spmi-gpio: hardcode IRQ counts
The probing of this driver calls platform_irq_count, which will
setup all of the IRQs that are configured in device tree. In
preparation for converting this driver to be a hierarchical IRQ
chip, hardcode the IRQ count based on the hardware type so that all
the IRQs are not configured immediately and are configured on an
as-needed basis later in the boot process. This change will also
allow for the removal of the interrupts property later in this
patch series once the hierarchical IRQ chip support is in.

This patch also removes the generic qcom,spmi-gpio OF match since we
don't know the number of pins. All of the existing upstream bindings
already include the more-specific binding.

The pm8941 code was tested on a LG Nexus 5 (hammerhead) phone.

When declaring the HSPI RX1_B and TX1_B pins, two mistakes were made:
  - the rows and columns in the BGA pin matrix, from which the pin
    numbers are derived, were exchanged,
  - it was not taken into account that pin row labelling skips
    characters I, O, Q, and S.

Fix the order, and the corresponding pin names.

Notes:
  - The actual values of the pin numbers don't really matter (they just
    have to be unique), so the wrong order didn't have any impact,
  - Changing the names of the pins is user-visible, but there are no
    users in (upstream) DTS files.

ca4438442e pinctrl: sunxi: Consider pin_base when calculating regulator array index
On most newer Allwinner SoCs, there are two pinctrl devices, the PIO and
R_PIO. PIO covers pin-banks PA to PI (PJ and PK have not been seen),
while R_PIO covers PL to PN. The regulator array only has space for 12
entries, which was designed to cover PA to PL. On the A80, the pin banks
go up to PN, which would be the 14th entry in the regulator array.
However since the driver only needs to track regulators for its own pin
banks, the array only needs to have 9 entries, and also take in to
account the value of pin_base, such that the regulator for the first
pin-bank of the pinctrl device, be it "PA" or "PL" uses the first entry
of the array.

Base the regulator array index on pin_base, such that "PA" for PIO and
"PL" for R_PIO both take the first element within their respective
device's regulator array.

Also decrease the size of the regulator array to 9, just enough to cover
"PA" to "PI".

dc14455841 pinctrl: sunxi: Fix and simplify pin bank regulator handling
The new per-pin-bank regulator handling code in the sunxi pinctrl driver
has mismatched conditions for enabling and disabling the regulator: it
is enabled each time a pin is requested, but only disabled when the
pin-bank's reference count reaches zero.

Since we are doing reference counting already, there's no need to enable
the regulator each time a pin is requested. Instead we can just do it
for the first requested pin of each pin-bank. Thus we can reverse the
test and bail out early if it's not the first occurrence.

6daae00243 pinctrl: meson: meson8b: add the eth_rxd2 and eth_rxd3 pins
Gigabit Ethernet requires the Ethernet TXD0..3 and RXD0..3 data lines.
Add the missing eth_rxd2 and eth_rxd3 definitions so we don't have to
rely on the bootloader to set them up correctly.

The vendor u-boot sources for Odroid-C1 use the following Ethernet
pinmux configuration:
  SET_CBUS_REG_MASK(PERIPHS_PIN_MUX_6, 0x3f4f);
  SET_CBUS_REG_MASK(PERIPHS_PIN_MUX_7, 0xf00000);
This translates to the following pin groups in the mainline kernel:
- register 6 bit  0: eth_rxd1 (DIF_0_P)
- register 6 bit  1: eth_rxd0 (DIF_0_N)
- register 6 bit  2: eth_rx_dv (DIF_1_P)
- register 6 bit  3: eth_rx_clk (DIF_1_N)
- register 6 bit  6: eth_tx_en (DIF_3_P)
- register 6 bit  8: eth_ref_clk (DIF_3_N)
- register 6 bit  9: eth_mdc (DIF_4_P)
- register 6 bit 10: eth_mdio_en (DIF_4_N)
- register 6 bit 11: eth_tx_clk (GPIOH_9)
- register 6 bit 12: eth_txd2 (GPIOH_8)
- register 6 bit 13: eth_txd3 (GPIOH_7)
- register 7 bit 20: eth_txd0_0 (GPIOH_6)
- register 7 bit 21: eth_txd1_0 (GPIOH_5)
- register 7 bit 22: eth_rxd3 (DIF_2_P)
- register 7 bit 23: eth_rxd2 (DIF_2_N)

All functions except eth_rxd2 and eth_rxd3 are already supported by the
pinctrl-meson8b driver.

1e11820f72 pinctrl: sirf: atlas7: use struct_size() in devm_kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    void *entry[];
};

instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL);

This code was detected with the help of Coccinelle.

f83f97684a pinctrl: sh-pfc: Make pinmux_cfg_reg.var_field_width[] variable-length
pinmux_cfg_reg.var_field_width[] is actually a variable-length array,
terminated by a zero, and counting at most r_width entries.
Usually the number of entries is much smaller than r_width, so the
ability to catch bugs at compile time through an "excess elements in
array initializer" warning is fairly limited.

Hence make the array variable-length, decreasing kernel size slightly.

ce16e8dd0d pinctrl: sh-pfc: Print actual field width for variable-width fields
The debug code in sh_pfc_write_config_reg() prints the width of the
field being modified.

However, registers with a variable-width field layout are identified by
pinmux_cfg_reg.field_width being zero, hence zeroes are printed instead
of the actual field widths.

Fix this by printing the Hamming weight of the field mask instead, which
is correct for both fixed-width and variable-width fields.

Fixing this makes all HSCIF0 pins use Function 4 (value 3), like was

This patch is based on commit a86caa9ba5 ("pinctrl: msm: fix gpio-hog

It fixes the issue that the gpio ranges needs to be defined before
gpiochip_add().

Therefore, we also have to swap the order of registering the pinctrl
driver and registering the gpio chip.

You also have to add the "gpio-ranges" property to the pinctrl device
node to get it finally working.
