dts: Added overlay for gpio_ir_recv driver #1199

Looks reasonable to me. @pelwell ? |

It looks OK to me (I'm away and can't test it though). Just FYI the strings "off", "down" and "up" translate to the values 0, 1 and 2 when assigning to an integer dtparam. |
Wow, this devicetree stuff is really magic ;) I will change the comments and doc accordingly in a follow-up commit shortly. |

Can you squash the commits together and force push? ( |

Thanks for squashing - we don't receive notifications for a push, hence the slow response. My automated checker spotted that a parameter name was incorrect in the README, and while I was correcting that I spotted the absence of "dtoverlay=" in the Load: section, so I've patched it up and pushed the new commit. I've also improved the checker and corrected some similar issues elsewhere in the README - I can see where you copied it from. Thanks for the contribution. |

This PR adds a DTS that allows the use of the gpio_ir_recv kernel driver.
The gpio_ir_recv driver is a rc-core based driver for TSOP-style IR receivers connected to a GPIO pin and is part of the Linux kernel. In contrast to lirc_rpi, no LIRC is needed for IR signal decoding or RC key mapping. These tasks are done by proven kernel infrastructure instead.
In contrast to the LIRC/lirc_rpi approach, the gpio_ir_recv driver brings a better RC responsiveness and a more consistent timing between RC button pressed and and key event and does not suffer from the typical double-key problems often reported from the lirc_rpi/LIRCd approach.
