Hi Linus,

here is the bulk of GPIO changes for the v5.11 kernel cycle.

The contents are explained in the signed tag as usual.

I had some more core patches boiling, but given your clear desire in
the release mail for v5.10 I quickly decided to pull that out and have
it wait for the next kernel cycle.

For the next kernel cycle the GPIO co-maintainer Bartosz Golaszewski
will be sending pull requests with fixes and also the bulk material for
v5.12. He has a kernel.org account so this should not be any infrastructural
problem.

Please pull it in!

Yours,
Linus Walleij

----------------------------------------------------------------
This is the bulk of the GPIO changes for the v5.11 kernel cycle:

Core changes:

- Retired the old set-up function for GPIO IRQ chips. All chips
now use the template struct gpio_irq_chip and pass that to the core
to be set up alongside the gpio_chip. We can finally get rid of
the old cruft.

- Some refactoring and clean up of the core code.

- Support edge event timestamps to be stamped using REALTIME
(wall clock) timestamps. We have found solid use cases for
this, so we support it.

New drivers:

- MStar MSC313 GPIO driver.

- HiSilicon GPIO driver.

Driver improvements:

- The PCA953x driver now also supports the NXP PCAL9554B/C chips.

- The mockup driver can now be probed from the device tree which
is pretty useful for virtual prototyping of devices.

- The Rcar driver now supports .get_multiple()

- The MXC driver dropped some legacy and became a pure device
tree client.

- The Exar driver was moved over to the IDA interface for
enumerating, and also switched over to using regmap for
register access.
