[PATCH 8/9] rt2x00: Add rt3090 support in rt2800 register initialization.

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

 

Add RT3090 specific register initializations to rt2x00, based on the latest
Ralink rt3090 vendor driver.

Untested as I don't actually own an RT3090 based device, but given experiences
on rt3070/rt3071 very hopeful that this will actually work..
