[PATCH 00/16] gpio: Tight IRQ chip integration and banked infrastructure

[Thierry Reding]

From: Thierry Reding <treding@xxxxxxxxxx>

Hi Linus,

here's the latest series of patches that implement the tighter IRQ chip
integration as well as the banked GPIO infrastructure that we had
discussed a couple of weeks/months back.

The first couple of patches are mostly preparatory work in order to
consolidate all IRQ chip related fields in a new structure and create
the base functionality for adding IRQ chips.

After that, I've added the Tegra186 GPIO support patch that makes use of
the new tight integration.

To round things off the new banked GPIO infrastructure is added (along
with some more preparatory work), followed by the conversion of the two
Tegra GPIO drivers to the new infrastructure.

Any thoughts on this? I'd like to target 4.15 with this, unless you'd be
willing to take this into 4.14, which I doubt at this point. The absence
of a GPIO driver has been hampering Tegra186 support upstream for a
while now, so it'd be good to make progress on this.

All of the patches are bisectible, at least to the point where I was
able to compile (there are a couple of odd users of linux/gpio/driver.h
that I either couldn't figure out the right Kconfig options to enable or
didn't have a cross-compiler for). I've carried these patches in my
development tree for a couple of weeks now, though, and the 0-day
builder hasn't had any complaints in a while. I also have a local cocci
patch for the move of fields to struct gpio_irq_chip and it gives an
empty patch when run on top of these patches on top of linux-next, so I
am fairly confident that this is all good to go.

Thierry
