[PATCH AUTOSEL 5.5 008/542] pinctrl: baytrail: Allocate IRQ chip dynamic

[PATCH AUTOSEL 5.5 008/542] pinctrl: baytrail: Allocate IRQ chip dynamic

[Sasha Levin]

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

[ Upstream commit 539d8bde72c22d760013bf81436d6bb94eb67aed ]

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.

[PATCH AUTOSEL 5.5 030/542] pinctrl: sh-pfc: r8a77965: Fix DU_DOTCLKIN3 drive/bias control

[Sasha Levin]

From: Geert Uytterhoeven <geert+renesas@glider.be>

[ Upstream commit a34cd9dfd03fa9ec380405969f1d638bc63b8d63 ]

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.

[PATCH AUTOSEL 5.5 035/542] pinctrl: sh-pfc: sh7264: Fix CAN function GPIOs

[Sasha Levin]

From: Geert Uytterhoeven <geert+renesas@glider.be>

[ Upstream commit 55b1cb1f03ad5eea39897d0c74035e02deddcff2 ]

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:
  [1] Figure 1.2 (3) (Pin Assignment for the SH7264 Group (1-Mbyte
      Version),
  [2] Figure 1.2 (4) Pin Assignment for the SH7264 Group (640-Kbyte
      Version,
  [3] Table 1.4 List of Pins,
  [4] Figure 20.29 Connection Example when Using This Module as 1-Channel
      Module (64 Mailboxes x 1 Channel),
  [5] Table 32.10 Multiplexed Pins (Port J),
  [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.

[PATCH AUTOSEL 5.5 050/542] gpio: gpio-grgpio: fix possible sleep-in-atomic-context bugs in grgpio_irq_map/unmap()

[Sasha Levin]

From: Jia-Ju Bai <baijiaju1990@gmail.com>

[ Upstream commit e36eaf94be8f7bc4e686246eed3cf92d845e2ef8 ]

The driver may sleep while holding a spinlock.
The function call path (from bottom to top) in Linux 4.19 is:

drivers/gpio/gpio-grgpio.c, 261:
	request_irq in grgpio_irq_map
drivers/gpio/gpio-grgpio.c, 255:
	_raw_spin_lock_irqsave in grgpio_irq_map

drivers/gpio/gpio-grgpio.c, 318:
	free_irq in grgpio_irq_unmap
drivers/gpio/gpio-grgpio.c, 299:
	_raw_spin_lock_irqsave in grgpio_irq_unmap

request_irq() and free_irq() can sleep at runtime.

To fix these bugs, request_irq() and free_irq() are called without
holding the spinlock.

These bugs are found by a static analysis tool STCheck written by myself.

[PATCH AUTOSEL 5.5 060/542] pinctrl: baytrail: Do not clear IRQ flags on direct-irq enabled pins

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ 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().

[PATCH AUTOSEL 5.5 272/542] pinctrl: sh-pfc: r8a7778: Fix duplicate SDSELF_B and SD1_CLK_B

[Sasha Levin]

From: Geert Uytterhoeven <geert+renesas@glider.be>

[ Upstream commit 805f635703b2562b5ddd822c62fc9124087e5dd5 ]

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.

[PATCH AUTOSEL 5.5 273/542] pinctrl: sh-pfc: sh7269: Fix CAN function GPIOs

[Sasha Levin]

From: Geert Uytterhoeven <geert+renesas@glider.be>

[ 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[].

[PATCH AUTOSEL 5.5 361/542] gpiolib: Set lockdep class for hierarchical irq domains

This is because the msm_gpio_irq_set_wake() function calls
irq_set_irq_wake() as a backup in case the irq comes in during the path
to idle. Given that we're calling irqchip functions from within an
irqchip we need to set the lockdep class to be different for this child
controller vs. the default one that the parent irqchip gets.

This used to be done before this driver was converted to hierarchical
irq domains in commit e35a6ae0eb3a ("pinctrl/msm: Setup GPIO chip in
hierarchy") via the gpiochip_irq_map() function. With hierarchical irq
domains this function has been replaced by
gpiochip_hierarchy_irq_domain_alloc(). Therefore, set the lockdep class
like was done previously in the irq domain path so we can avoid this
lockdep warning.

[PATCH AUTOSEL 5.5 383/542] gpio: Fix the no return statement warning

[Sasha Levin]

From: Kevin Hao <haokexin@gmail.com>

[ Upstream commit 9c6722d85e92233082da2b3623685bba54d6093e ]

In commit 242587616710 ("gpiolib: Add support for the irqdomain which
doesn't use irq_fwspec as arg") we have changed the return type of
gpiochip_populate_parent_fwspec_twocell/fourcell() from void to void *,
but forgot to add a return statement for these two dummy functions.
Add "return NULL" to fix the build warnings.

[PATCH AUTOSEL 5.5 384/542] pinctrl: tigerlake: Tiger Lake uses _HID enumeration

[Sasha Levin]

From: Mika Westerberg <mika.westerberg@linux.intel.com>

[ Upstream commit cd0a32371db73d0b50536a7ca4f036abddff0d1d ]

Turns out that Tiger Lake GPIO will be enumerated using _HID method where
there is only a single ACPI device and multiple BARs so rework the driver
to support that scheme instead.

Hi Sasha,

This commit shouldn't go to the v5.5.x kernel. This is a fix for the
commit 242587616710, but that commit doesn't exist in the v5.5.x kernel,
then it will trigger a build warning due to the wrong returning type.

Thanks,
Kevin
