Subject: [GIT PULL] GPIO bulk changes for v5.2
Hi Linus,
here is the big pull request for GPIO for v5.2. A bit later than usual
because I was ironing out my own mistakes. I'm holding some
stuff back for the next kernel as a result, and this should be a
healthy and well tested batch.
I merged in v5.1-rc3 at one point to get rid of some nasty merge
conflicts with one of the bigger fixes that went in in the early rcs.
Other than that it is business as usual and a not very busy kernel
cycle this time.
Please pull it in!
Yours,
Linus Walleij

gpio: Update documentation (2019-05-07 16:32:12 +0200)
----------------------------------------------------------------
This is the bulk of the GPIO changes for the v5.2 kernel cycle:
Core changes:
- The gpiolib MMIO driver has been enhanced to handle two direction
registers, i.e. one register to set lines as input and one register
to set lines as output. It turns out some silicon engineer thinks
the ability to configure a line as input and output at the same
time makes sense, this can be debated but includes a lot of analog
electronics reasoning, and the registers are there and need to
be handled consistently. Unsurprisingly, we enforce the lines to
be either inputs or outputs in such schemes.
- Send in the proper argument value to .set_config() dispatched to
the pin control subsystem. Nobody used it before, now someone
does, so fix it to work as expected.
- The ACPI gpiolib portions can now handle pin bias setting (pull up
or pull down). This has been in the ACPI spec for years and we
finally have it properly integrated with Linux GPIOs. It was based
on an observation from Andy Schevchenko that Thomas Petazzoni's
changes to the core for biasing the PCA950x GPIO expander actually
happen to fit hand-in-glove with what the ACPI core needed.
Such nice synergies happen sometimes.
New drivers:
- A new driver for the Mellanox BlueField GPIO controller. This is
using 64bit MMIO registers and can configure lines as inputs
and outputs at the same time and after improving the MMIO library
we handle it just fine. Interesting.
- A new IXP4xx proper gpiochip driver with hierarchical interrupts
should be coming in from the ARM SoC tree as well.
Driver enhancements:
- The PCA053x driver handles the CAT9554 GPIO expander.
- The PCA053x driver handles the NXP PCAL6416 GPIO expander.
- Wake-up support on PCA053x GPIO lines.
- OMAP now does a nice asynchronous IRQ handling on wake-ups by
letting everything wake up on edges, and this makes runtime PM
work as expected too.
Misc:
- Several cleanups such as devres fixes.
- Get rid of some languager comstructs that cause problems when
compiling with LLVMs clang.
- Documentation review and update.
