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!
