[PATCH AUTOSEL 4.19 089/209] media: rc: ir-rc6-decoder: enable toggle bit for Kathrein RCU-676 remote

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Matthias Reichl <hias@xxxxxxxxx>

[ Upstream commit 85e4af0a7ae2f146769b7475ae531bf8a3f3afb4 ]

The Kathrein RCU-676 remote uses the 32-bit rc6 protocol and toggles
bit 15 (0x8000) on repeated button presses, like MCE remotes.

Add it's customer code 0x80460000 to the 32-bit rc6 toggle
handling code to get proper scancodes and toggle reports.
