[RFC 16/24] SERIAL: omap: simplify

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

 



We have the sequence:
	- LCR mode B
	- write EFR with ECB clear
	- LCR mode normal
	- LCR mode B
	- write EFR with ECB clear

This can be simplified to just two writes:
	- LCR mode B
	- write EFR with ECB clear
