pinctrl: mt7622: fix a kernel panic when pio don't work as EINT controller
The function, external interrupt controller, is made as an optional to
mt7622 pinctrl. But if we don't want pio behaves as an external interrupt
controller, it would lead to hw->eint not be created properly and then
will cause 'kernel NULL pointer' issue when gpiochip try to call .to_irq
or .set_config. To fix it, check hw->eint before accessing the member.

pinctrl: actions: Fix uninitialized error in owl_pin_config_set()
With gcc 4.1.2:
drivers/pinctrl/actions/pinctrl-owl.c: In function ‘owl_pin_config_set’:
drivers/pinctrl/actions/pinctrl-owl.c:336: warning: ‘ret’ may be used uninitialized in this function
Indeed, if num_configs is zero, the uninitialized value will be returned
as an error code.
Fix this by preinitializing it to zero.

pinctrl: single: Add allocation failure checking of saved_vals
Currently saved_vals is being allocated and there is no check for
failed allocation (which is more likely than normal when using
GFP_ATOMIC). Fix this by checking for a failed allocation and
propagating this error return down the the caller chain.

treewide: devm_kzalloc() -> devm_kcalloc()
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:
devm_kzalloc(handle, a * b, gfp)
with:
devm_kcalloc(handle, a * b, gfp)
as well as handling cases of:
devm_kzalloc(handle, a * b * c, gfp)
with:
devm_kzalloc(handle, array3_size(a, b, c), gfp)
as it's slightly less ugly than:
devm_kcalloc(handle, array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
devm_kzalloc(handle, 4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".
The Coccinelle script used for this was:

treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:
kzalloc(a * b, gfp)
with:
kcalloc(a * b, gfp)
as well as handling cases of:
kzalloc(a * b * c, gfp)
with:
kzalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kzalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kzalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The Coccinelle script used for this was:
// Fix redundant parens around sizeof().

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd: "This time we have a good set of changes to the core framework that do some general cleanups, but nothing too major. The majority of the diff goes to two SoCs, Actions Semi and Qualcomm. A brand new driver is introduced for Actions Semi so it takes up some lines to add all the different types, and the Qualcomm diff is there because we add support for two SoCs and it's quite a bit of data. Otherwise the big driver updates are on TI Davinci and Amlogic platforms. And then the long tail of driver updates for various fixes and stuff follows after that. Core: - debugfs cleanups removing error checking and an unused provider API - Removal of a clk init typedef that isn't used - Usage of match_string() to simplify parent string name matching - OF clk helpers moved to their own file (linux/of_clk.h) - Make clk warnings more readable across kernel versions New Drivers: - Qualcomm SDM845 GCC and Video clk controllers - Qualcomm MSM8998 GCC - Actions Semi S900 SoC support - Nuvoton npcm750 microcontroller clks - Amlogic axg AO clock controller Removed Drivers: - Deprecated Rockchip clk-gate driver Updates: - debugfs functions stopped checking return values - Support for the MSIOF module clocks on Rensas R-Car M3-N - Support for the new Rensas RZ/G1C and R-Car E3 SoCs - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs - Berlin and Amlogic SPDX tagging - Usage of of_clk_get_parent_count() in more places - Proper implementation of the CDEV1/2 clocks on Tegra20 - Allwinner H6 PRCM clock support and R40 EMAC support - Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet - Round closest support for meson's mpll driver - Support for meson8b nand clocks and gxbb video decoder clocks - Mediatek mali clks - STM32MP1 fixes - Uniphier LD11/LD20 stream demux system clock" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (134 commits) clk: qcom: Export clk_fabia_pll_configure() clk: bcm: Update and add Stingray clock entries dt-bindings: clk: Update Stingray binding doc clk-si544: Properly round requested frequency to nearest match clk: ingenic: jz4770: Add 150us delay after enabling VPU clock clk: ingenic: jz4770: Enable power of AHB1 bus after ungating VPU clock clk: ingenic: jz4770: Modify C1CLK clock to disable CPU clock stop on idle clk: ingenic: jz4770: Change OTG from custom to standard gated clock clk: ingenic: Support specifying "wait for clock stable" delay clk: ingenic: Add support for clocks whose gate bit is inverted clk: use match_string() helper clk: bcm2835: use match_string() helper clk: Return void from debug_init op clk: remove clk_debugfs_add_file() clk: tegra: no need to check return value of debugfs_create functions clk: davinci: no need to check return value of debugfs_create functions clk: bcm2835: no need to check return value of debugfs_create functions clk: no need to check return value of debugfs_create functions clk: imx6: add EPIT clock support clk: mvebu: use correct bit for 98DX3236 NAND ... |

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for v4.18.
No core changes this time! Just a calm all-over-the-place drivers,
updates and fixes cycle as it seems.
New drivers/subdrivers:
- Actions Semiconductor S900 driver with more Actions variants for
S700, S500 in the pipe. Also generic GPIO support on top of the
same driver and IRQ support is in the pipe.
- Renesas r8a77470 PFC support.
- Renesas r8a77990 PFC support.
- Allwinner Sunxi H6 R_PIO support.
- Rockchip PX30 support.
- Meson Meson8m2 support.
- Remove support for the ill-fated Samsung Exynos 5440 SoC.
Improvements:
- Context save/restore support in pinctrl-single.
- External interrupt support for the Mediatek MT7622.
- Qualcomm ACPI HID QCOM8002 supported.

Merge tag 'overflow-v4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull overflow updates from Kees Cook:
"This adds the new overflow checking helpers and adds them to the
2-factor argument allocators. And this adds the saturating size
helpers and does a treewide replacement for the struct_size() usage.
Additionally this adds the overflow testing modules to make sure
everything works.
I'm still working on the treewide replacements for allocators with
"simple" multiplied arguments:
*alloc(a * b, ...) -> *alloc_array(a, b, ...)
and
*zalloc(a * b, ...) -> *calloc(a, b, ...)
as well as the more complex cases, but that's separable from this
portion of the series. I expect to have the rest sent before -rc1
closes; there are a lot of messy cases to clean up.
Summary:
- Introduce arithmetic overflow test helper functions (Rasmus)
- Use overflow helpers in 2-factor allocators (Kees, Rasmus)
- Introduce overflow test module (Rasmus, Kees)
- Introduce saturating size helper functions (Matthew, Kees)
- Treewide use of struct_size() for allocators (Kees)"

pinctrl: cherryview: limit Strago DMI workarounds to version 1.0
As Google/Intel will fix the BIOS/Coreboot issues with hardcoding virtual interrupt numbers for keyboard/touchpad/touchscreen controllers in ACPI tables, they will also update BOARD version number from 1.0 to 1.1. Let's limit the DMI quirks that try to preserve virtual IRQ numbers on Strago boards to those that still carry older BIOSes. Note that ideally not BOARD but BIOS version should have been updated. However the BIOS version used by Chrome devices has format of Google_BUILD.BRANCH.PATCH which is not well suited for DMI matching as we do not have "less than" match mode for DMI data.

pinctrl: armada-37xx: Fix spurious irq management
Until now, if we found spurious irq in irq_handler, we only updated the
status in register but not the status in the code. Due to this the system
will got stuck dues to the infinite loop

pinctrl: msm: fix gpio-hog related boot issues
Sven Eckelmann reported an issue with the current IPQ4019 pinctrl.
Setting up any gpio-hog in the device-tree for his device would
"kill the bootup completely":
| [ 0.477838] msm_serial 78af000.serial: could not find pctldev for node /soc/pinctrl@1000000/serial_pinmux, deferring probe
| [ 0.499828] spi_qup 78b5000.spi: could not find pctldev for node /soc/pinctrl@1000000/spi_0_pinmux, deferring probe
| [ 1.298883] requesting hog GPIO enable USB2 power (chip 1000000.pinctrl, offset 58) failed, -517
| [ 1.299609] gpiochip_add_data: GPIOs 0..99 (1000000.pinctrl) failed to register
| [ 1.308589] ipq4019-pinctrl 1000000.pinctrl: Failed register gpiochip
| [ 1.316586] msm_serial 78af000.serial: could not find pctldev for node /soc/pinctrl@1000000/serial_pinmux, deferring probe
| [ 1.322415] spi_qup 78b5000.spi: could not find pctldev for node /soc/pinctrl@1000000/spi_0_pinmux, deferri
This was also verified on a RT-AC58U (IPQ4018) which would
no longer boot, if a gpio-hog was specified. (Tried forcing
the USB LED PIN (GPIO0) to high.).
The problem is that Pinctrl+GPIO registration is currently
peformed in the following order in pinctrl-msm.c:
1. pinctrl_register()
2. gpiochip_add()
3. gpiochip_add_pin_range()
The actual error code -517 == -EPROBE_DEFER is coming from
pinctrl_get_device_gpio_range(), which is called through:
gpiochip_add
of_gpiochip_add
of_gpiochip_scan_gpios
gpiod_hog
gpiochip_request_own_desc
__gpiod_request
chip->request
gpiochip_generic_request
pinctrl_gpio_request
pinctrl_get_device_gpio_range
pinctrl_get_device_gpio_range() is unable to find any valid
pin ranges, since nothing has been added to the pinctrldev_list yet.
so the range can't be found, and the operation fails with -EPROBE_DEFER.
This patch fixes the issue by adding the "gpio-ranges" property to
the pinctrl device node of all upstream Qcom SoC. The pin ranges are
then added by the gpio core.
In order to remain compatible with older, existing DTs (and ACPI)
a check for the "gpio-ranges" property has been added to
msm_gpio_init(). This prevents the driver of adding the same entry
to the pinctrldev_list twice.

pinctrl: mediatek: refactor EINT related code for all MediaTek pinctrl can fit
This patch is in preparation for adding EINT support to MT7622 pinctrl, and the refactoring doesn't alter any existent logic. A reason we have to refactor EINT code pieces into a generic way is that currently, they're tightly coupled with a certain type of MediaTek pinctrl would cause a grown in a very bad way as there is different types of pinctrl devices getting to join. Therefore, it is an essential or urgent thing that EINT code pieces are refactored to eliminate any dependencies across GPIO and EINT as possible. Additional structure mtk_eint_[xt, hw, regs] are being introduced for indicating how maps being designed between GPIO and EINT hw number, how to set and get GPIO state for a certain EINT pin, what characteristic on a EINT device is present on various SoCs.

Merge tag 'samsung-pinctrl-4.18-2' of https://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/samsung into devel
Samsung pinctrl drivers changes for v4.18 1. Driver expects specific order of GPIO interrupt banks. For S5Pv220 and Exynos5410 this order was not preserved so fix and document it. 2. Remove support for Exynos5440 (tree-wide, support is dropped because there are no real users of this platform, it also did not get testing since long time). 3. Fix lost state of GPF1..5 pins on Exynos5433 during system suspend. |
