Preliminary version of patch adding support for AVerTV MCE 116 Plus remote.
This board has an IR sensor is connected to EM78P153S, general purpose 8-bit
microcontroller with a 1024 × 13 bits of OTP-ROM. According to i2cdetect, it is
sitting on address 0x40.
Patch allows ir-kbd-i2c to probe cx2341x boards for this address. Manually
loading ir-kbd-i2c now detects remote, every key is working as expected.
As I understand, current I2C/probing code is being redesigned/refactored. Sheer
amount of #ifdefs for every second kernel version is making my eyes bleed, so
please somebody involved check if patch is ok.
Should I also add the 0x40 address to addr_list[] in ivtv-i2c.c? How to point
ivtv to this remote and autoload ir-kbd-i2c?
