Subject: [GIT PULL] Bulk GPIO changes for v5.8
Hi Linus,
here is the bulk of GPIO changes for the v5.8 kernel cycle.
Nothing too exciting, details in the signed tag.
Some new functionality was added on top of massive
fixes so that is why I merged in v5.7-rc7 to make it
apply without creating a mess.
Please pull it in!
Med vänlig hälsning,
Linus Walleij

gpio: pca953x: Drop unneeded ACPI_PTR() (2020-06-03 14:04:28 +0200)
----------------------------------------------------------------
This is the bulk of GPIO changes for the v5.8 kernel cycle.
Core changes:
- A new GPIO aggregator driver has been merged: this can
join a few select GPIO lines into a new aggregated GPIO
chip. This can be used for security: a process can be
granted access to only these lines, for example for
industrial control. Another way to use this is to
reexpose certain select lines to a virtual machine or
container.
- Warn if the gpio-line-names is too long in he DT parser
core.
- GPIO lines can now be looked up by line name in addition
to being looked up by offset.
New drivers:
- A new generic regmap GPIO driver has been merged. Too
many regmap drivers are starting to look like each other
so we need to create some common ground and try to move
drivers over to using that.
- The F7188X driver now supports F81865.
Driver improvements:
- Large improvements to the PCA953x expander, get multiple lines
and several cleanups.
- Large improvements to the DesignWare DWAPB driver, and Sergey
Semin has volunteered to maintain it.
- PL061 can now be built as a module, this is part of a bigger
effort to make the ARM platforms more modular.
