This is the case here. Before the RC subsystem, the decoding for NEC and RC-5 were done inside ir-core (at ir-functions). Also, all the keymap entries (RC_MAP) were compiled in-kernel. The intention is to move the RC_MAP keytables to userspace, by default, but there are still some work to be done at the userspace application before we can do it. So, without RC_MAP, IR_NEC_DECODER and IR_RC5_DECODER, the input driver will be compiled, but the IR support may not actually work, if the board needs IR raw support. That's said, the support for RC-6, JVC and Sony protocols (IR_RC6_DECODER, IR_JVC_DECODER and IR_SONY_DECODER) are new. Yet, even on this case, it may make sense to keep the default to Y, or to add a logic to auto-select the IR decoder protocols that are needed in order to support the bundled IR found at the compiled drivers. -- Cheers, Mauro -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
