e66ff71fd0 pinctrl: lewisburg: Update pin list according to v1.1v6
Version 1.1v6 of pin list has some changes in pin names for Intel Lewisburg.

Update the driver accordingly.

Note, it reveals the bug in the driver that misses two pins in GPP_L and
has rather two extra ones. That's why the ordering of some groups is changed.

04fb02757a pinctrl: armada-37xx: Fix irq mask access in armada_37xx_irq_set_type()
As explained in the following commit a9a1a48336 ("pinctrl:
armada-37xx: Fix gpio interrupt setup") the armada_37xx_irq_set_type()
function can be called before the initialization of the mask field.

That means that we can't use this field in this function and need to
workaround it using hwirq.

1948d5c51d pinctrl: Add pinmux & GPIO controller driver for a new SoC
Intel Lightning Mountain SoC has a pinmux controller & GPIO controller IP which
controls pin multiplexing & configuration including GPIO functions selection &
GPIO attributes configuration.

This IP is not based on & does not have anything in common with Chassis
specification. The pinctrl drivers under pinctrl/intel/* are all based upon
Chassis spec compliant pinctrl IPs. So this driver doesn't fit & can not use
pinctrl framework under pinctrl/intel/* and it requires a separate new driver.

Add a new GPIO & pin control framework based driver for this IP.

54787d7c14 pinctrl: rza1: remove unnecessary static inline function
Having static inline oneliner does not benefit too much when it is
only called from another oneliner function. Remove some of the
'onion'. This simplifies also the coming usage of the gpiolib
defines. We can do conversion from chip bits to gpiolib direction
defines as last step in the get_direction callback. Drivers can
use chip specific values in driver internal functions and do
conversion only once.

dabad1ff85 pinctrl: meson: add pinctrl driver support for Meson-A1 SoC
Meson A1 SoC share the same register layout of pinmux with previous
Meson-G12A, however there is difference for gpio and pin config register
in A1. The main difference is that registers before A1 are grouped by
function while those of A1 are by bank. The new register layout is as
below:

/* first bank */              /* addr */
- P_PADCTRL_GPIOP_I         base + 0x00 << 2
- P_PADCTRL_GPIOP_O         base + 0x01 << 2
- P_PADCTRL_GPIOP_OEN       base + 0x02 << 2
- P_PADCTRL_GPIOP_PULL_EN   base + 0x03 << 2
- P_PADCTRL_GPIOP_PULL_UP   base + 0x04 << 2
- P_PADCTRL_GPIOP_DS        base + 0x05 << 2

/* second bank */
- P_PADCTRL_GPIOB_I         base + 0x10 << 2
- P_PADCTRL_GPIOB_O         base + 0x11 << 2
- P_PADCTRL_GPIOB_OEN       base + 0x12 << 2
- P_PADCTRL_GPIOB_PULL_EN   base + 0x13 << 2
- P_PADCTRL_GPIOB_PULL_UP   base + 0x14 << 2
- P_PADCTRL_GPIOB_DS        base + 0x15 << 2

Each bank contains at least 6 registers to be configured, if one bank
has more than 16 gpios, an extra P_PADCTRL_GPIO[X]_DS_EXT is included.
Between two adjacent P_PADCTRL_GPIO[X]_I, there is an offset 0x10, that
is to say, for third bank, the offsets will be 0x20,0x21,0x22,0x23,0x24
,0x25 according to above register layout. For previous chips, registers
are grouped according to their functions while registers of A1 are
according to bank.Also note that there is no AO bank any more in A1.

Current Meson pinctrl driver can cover such change by using base address
of GPIO as that of drive-strength. While simply giving reg_ds = reg_pullen
make wrong value to reg_ds for Socs that do not support drive-strength
like AXG.To make things simple, add an extra dt parser function for
a1 and remain the old dt parser function for only reg parsing.

fd42296407 pinctrl: meson: add a new callback for SoCs fixup
In meson_pinctrl_parse_dt, it contains two parts: reg parsing and
SoC relative fixup for AO. Several fixups in the same code make it hard
to maintain, so move all fixups to each SoC's callback and make
meson_pinctrl_parse_dt just do the reg parsing, separate these two
parts.Overview of all current Meson SoCs fixup is as below:

|      |  pull = gpio; pull-enable = gpio; ds = gpio;                    |
+------+-----------------------------------------------------------------+
Since m8-axg share the same ao fixup, make a common function
meson8_aobus_parse_dt_extra to do the job.

58afa801ef pinctrl: nomadik: db8500: Add mc0_a_2 pin group without direction control
Some devices do not make use of the CMD0/DAT0/DAT2 direction control
pins of the MMC/SD card 0 interface. In this case we should leave
those pins unconfigured.

A similar case already exists for "mc1_a_1" vs "mc1_a_2"
when the MC1_FBCLK pin is not used.

Add a new "mc0_a_2" pin group which is equal to "mc0_a_1" except
with the MC0_CMDDIR, MC0_DAT0DIR and MC0_DAT2DIR pins removed.

e58e177392 pinctrl: cherryview: Allocate IRQ chip dynamic
Keeping the IRQ chip definition static shares it with multiple instances
of the GPIO chip in the system. This is bad and now we get this warning
from GPIO library:

"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
intel_pinctrl. So a unique IRQ chip is used for each GPIO chip instance.

This patch is heavily based on the attachment to the bug by Christoph Marz.

3739898576 pinctrl: cherryview: Fix irq_valid_mask calculation
Commit 03c4749dd6 ("gpio / ACPI: Drop unnecessary ACPI GPIO to Linux
GPIO translation") has made the cherryview gpio numbers sparse, to get
a 1:1 mapping between ACPI pin numbers and gpio numbers in Linux.

This has greatly simplified things, but the code setting the
irq_valid_mask was not updated for this, so the valid mask is still in
the old "compressed" numbering with the gaps in the pin numbers skipped,
which is wrong as irq_valid_mask needs to be expressed in gpio numbers.

This results in the following error on devices using pin 24 (0x0018) on
the north GPIO controller as an ACPI event source:

[    0.422452] cherryview-pinctrl INT33FF:01: Failed to translate GPIO to IRQ

This has been reported (by email) to be happening on a Caterpillar CAT T20
tablet and I've reproduced this myself on a Medion Akoya e2215t 2-in-1.

This commit uses the pin number instead of the compressed index into
community->pins to clear the correct bits in irq_valid_mask for GPIOs
using GPEs for interrupts, fixing these errors and in case of the
Medion Akoya e2215t also fixing the LID switch not working.

4973ddc842 pinctrl: intel: Avoid potential glitches if pin is in GPIO mode
When consumer requests a pin, in order to be on the safest side,
we switch it first to GPIO mode followed by immediate transition
to the input state. Due to posted writes it's luckily to be a single
I/O transaction.

However, if firmware or boot loader already configures the pin
to the GPIO mode, user expects no glitches for the requested pin.
We may check if the pin is pre-configured and leave it as is
till the actual consumer toggles its state to avoid glitches.
