Hi,
Since kernel linux-raspberrypi 4.19.23-1, rpi lirc support seems to have disappeared.
There is no lirc-rpi.dtbo overlay file any more and no lirc_rpi and lirc_dev kernel modules.
Looking at this commit https://github.com/archlinuxarm/PKGBUILDs/commit/af8f84fad41b9a46ea031e075bc6fdadaef8b900 it seems the corresponding kernel config options have been removed:
$this->bbcode_second_pass_code('', 'CONFIG_LIRC=m
CONFIG_IR_LIRC_CODEC=m
CONFIG_LIRC_STAGING=y
CONFIG_LIRC_RPI=m
CONFIG_LIRC_ZILOG=m')
Is there any particular reason for having removed these ?
