Subject: [RFC 0/5] IR support for A83T - sunxi-ir driver update

This patch series adds support for the sunxi A83T ir module and enhances the sunxi-ir driver.
Right now the base clock frequency for the ir driver is a hard coded define and is set to 8 MHz.
This works for the most common ir receivers. On the Sinovoip Bananapi M3 the ir receiver needs,
a 3 MHz base clock frequency to work without problems with this driver (like in the legacy kernel).

To fix this issue I reworked the driver that this value could be set over the devicetree.

About 37 devices would have a devicetree change if this patch series would be applied.
Therfore I would like to ask you to give me some feedback about the patch series, before I finialize it.

Thanks in advance!

Philipp
