gitolite.kernel.org:pub/scm/linux/kernel/git/andy/linux-gpio-intel into gpio/for-next
intel-gpio for v6.1-1
* Add a quirk for Asus UM325UAZ to make GPIO interrupts working
|
|
There is no cyclic dependency between gpio_twl4030_probe() and
gpio_twl4030_remove(), so by moving the latter before the former the
forward declaration can be dropped.

Commit a2b5e207cade ("gpiolib: rework quirk handling in of_find_gpio()")

There is no need for of_find_spi_cs_gpio() to be different from other
quirks: the only variant of property actually used in DTS is "gpios"
(plural) so we can use of_get_named_gpiod_flags() instead of recursing
into of_find_gpio() again.
This will allow us consolidate quirk handling down the road.

Several ISA drivers feature IRQ support that can configured via an "irq"
array module parameter. This array typically matches directly with the
respective "base" array module parameter. To reduce code repetition, a
module_isa_driver_with_irq helper macro is introduced to provide a check
ensuring that the number of "irq" passed to the module matches with the
respective number of "base".

Add support for the NXP PCAL6534. This device is broadly a 34-bit version
of the PCAL6524. However, whilst the registers are broadly what you'd
expect for a 34-bit version of the PCAL6524, the spacing of the registers
has been compacted. This has the unfortunate effect of breaking the bit
shift based mechanism that is employed to work out register locations used
by the other chips supported by this driver. To accommodate ths, callback
functions have been added to allow alterate implementations of
pca953x_recalc_addr() and pca953x_check_register() for the PCAL6534.

A previous fix, commit dc87f6dd058a ("gpio: pca953x: Fix
pca953x_gpio_set_config"), identified that pinconf_to_config_param() needed
to be used to isolate the config_param from the pinconf in
pca953x_gpio_set_config(). This fix however did not consider that this
would also be needed in pca953x_gpio_set_pull_up_down() to which it passes
this config.
Perform a similar call in pca953x_gpio_set_pull_up_down() to isolate the
configuration parameter there as well, rather than passing it from
pca953x_gpio_set_config() as the configuration argument may also be needed
in pca953x_gpio_set_pull_up_down() at a later date.

Asus UM325UAZ has GPIO 18 programmed as both an interrupt and a wake

floating and shouldn't have been programmed. This causes lots of
spurious IRQs on the system and horrendous battery life.

Add GPIO support for Nuvoton NCT6116 chip. Nuvoton SuperIO chips are
very similar to the ones from Fintek. In other subsystems they also
share drivers and are called a family of drivers.
For the GPIO subsystem the only difference is that the direction bit is
reversed and that there is only one data bit per pin. On the SuperIO
level the logical device is another one.
On a chip level we do not have a manufacturer ID to check and also no
revision.
