[ Upstream commit 2c7e3306d23864d49f686f22e56e180ff0fffb7f ]

The DT bindings for pinctrl-bcm2835 allow both the function and pull
to contain either one entry or one per pin. However, an error in the
DT parsing can cause failures if the number of pulls differs from the
number of functions.

pinctrl: bcm2835: Fix support for threaded level triggered IRQs 2015-04-08T14:41:59+00:00 Charles Keepax ckeepax@opensource.wolfsonmicro.com 2015-04-07T10:43:45+00:00 b8a19382ac6212d18b21fcc7867060a5d54fe1a2 Currently, the driver uses handle_simple_irq for all IRQ types and hard codes the acknowledge for different IRQ types into the handler. It is better to use the IRQ core as intended and let it handle the differences between the various types of IRQ. For example the current system does not work for threaded level triggered IRQs as these need to be masked until the threaded handler has run.
