[PATCH 00/12] gpio: Tight IRQ chip integration and Tegra186 support

[Thierry Reding <thierry.reding@xxxxxxxxx>]

From: Thierry Reding <treding@xxxxxxxxxx>

Hi Linus,

here's a first draft of patches to make GPIOLIB_IRQCHIP flexible enough
to support the Tegra186 use-case. Instead of just fixing the bugs that I
had pointed out earlier, this goes one step further and completely
integrates IRQ chip registration into GPIO chip registration. The idea
is that drivers will initialize a set of fields (collected in a new
struct gpio_irq_chip) before calling gpiochip_add() (or derivatives) and
gpiolib will internally set up an IRQ domain and register the IRQ chip.

Currently this makes use of the new infrastructure only in the Tegra186
driver, but I plan to convert a couple of others once we can agree that
this is a direction that you're comfortable with.

Thierry
