Subject: [PATCH 32/70] MIPS: lantiq: convert falcon debug uart to clkdev api
|
||
|
|
|
||
|
|
On Falcon SoCs we have a secondary serial port that can be used to help
|
||
|
|
debug the voice core. For the port to work several clocking bits need to
|
||
|
|
be activated. We convert the code to clkdev api.
