2022-12-30pinctrl: baytrail: Convert to use new memeber in struct intel_functionAndy Shevchenko
Convert driver to use generic data type and hence a new member in the struct intel_function. No functional change intended. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com>
2022-12-30pinctrl: intel: Make use of struct pinfunction and PINCTRL_PINFUNCTION()Andy Shevchenko

2022-12-29pinctrl: mxs: avoid defines prefixed with CONFIGLukas Bulwahn
Defines prefixed with "CONFIG" should be limited to proper Kconfig options, that are introduced in a Kconfig file. Here, expressions to convert pin configurations to booleans for pull-up, voltage and mA are macro definitions that begin with "CONFIG". To avoid defines prefixed with "CONFIG", rename these defines to begin with "PIN_CONFIG" instead. No functional change.

The thunderbay_add_functions() will free memory of thunderbay_funcs when everything is ok, but thunderbay_funcs will not be freed when thunderbay_add_functions() fails, then there will be a memory leak, so we need to add kfree() when thunderbay_add_functions() fails to fix it.

2022-11-28pinctrl: intel: Save and restore pins in "direct IRQ" modeAndy Shevchenko
The firmware on some systems may configure GPIO pins to be an interrupt source in so called "direct IRQ" mode. In such cases the GPIO controller driver has no idea if those pins are being used or not. At the same time, there is a known bug in the firmwares that don't restore the pin settings correctly after suspend, i.e. by an unknown reason the Rx value becomes inverted. Hence, let's save and restore the pins that are configured as GPIOs in the input mode with GPIROUTIOXAPIC bit set.

There is a possibility of dividing by zero due to the pcs->bits_per_pin if pcs->fmask() also has a value of zero and called fls from asm-generic/bitops/builtin-fls.h or arch/x86/include/asm/bitops.h.
