Pull irq updates from Thomas Gleixner:
 "This is the second attempt after the first one failed miserably and
  got zapped to unblock the rest of the interrupt related patches.

  A treewide cleanup of interrupt descriptor (ab)use with all sorts of
  racy accesses, inefficient and disfunctional code. The goal is to
  remove the export of irq_to_desc() to prevent these things from
  creeping up again"

Merge tag 'pinctrl-v5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.11 kernel.

  Drivers, drivers and drivers. Not a single core change.

  Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot
  SoCs.

  As part of the modularization attempt, I applied one patch affecting
  the firmware subsystem as a functional (not syntactic/semantic)
  dependency and then it blew up in our face, so I had to revert it,
  bummer. It will come in later, through that subsystem, I guess.

  New drivers:

   - New driver for the Microchip Serial GPIO "SGPIO".

   - Qualcomm SM8250 LPASS (Low Power Audio Subsystem) GPIO driver.

  New subdrivers:

   - Intel Lakefield subdriver.

   - Intel Elkhart Lake subdriver.

   - Intel Alder Lake-S subdriver.

   - Qualcomm MSM8953 subdriver.

   - Qualcomm SDX55 subdriver.

   - Qualcomm SDX55 PMIC subdriver.

   - Ocelot Luton SoC subdriver.

   - Ocelot Serval SoC subdriver.

  Modularization:

   - The Meson driver can now be built as modules.

   - The Qualcomm driver(s) can now be built as modules.

  Incremental improvements:

   - The Intel driver now supports pin configuration for GPIO-related
     configurations.

   - A bunch of Renesas PFC drivers have been augmented with support for
     QSPI pins, groups and functions.

   - Non-critical fixes to the irq handling in the Allwinner Sunxi
     driver"

Pull staging / IIO driver updates from Greg KH:
 "Here is the big staging and IIO driver pull request for 5.11-rc1

  Lots of different things in here:

   - loads of driver updates

   - so many coding style cleanups

   - new IIO drivers

   - Android ION code is finally removed from the tree

   - wimax drivers are moved to staging on their way out of the kernel

  Nothing really exciting, just the constant grind of kernel development :)

  All have been in linux-next for a while with no reported issues"

pinctrl: use krealloc_array()

2020-12-15T20:13:37+00:00

Use the helper that checks for overflows internally instead of manually
calculating the size of the new array.

pinctrl: intel: Actually disable Tx and Rx buffers on GPIO request

2020-12-09T08:08:18+00:00

Mistakenly the buffers (input and output) become enabled together for a short
period of time during GPIO request. This is problematic, because instead of
initial motive to disable them in the commit af7e3eeb84e2
("pinctrl: intel: Disable input and output buffer when switching to GPIO"),
the driven value on the pin, which might be used as an IRQ line, brings
firmwares of some touch pads to an awkward state that needs a full power off
to recover. Fix this, as stated in the culprit commit, by disabling the buffers.

pinctrl: ralink: add a pinctrl driver for the rt2880 family

2020-12-08T08:58:01+00:00

These Socs have 1-3 banks of 8-32 gpios. Rather then setting the muxing of each
pin individually, these socs have mux groups that when set will effect 1-N pins.
Pin groups have a 2, 4 or 8 different muxes.
