[PATCH 8/8] clk: bcm2835: add the testdebug clock generators

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

 




From: Martin Sperl <kernel@xxxxxxxxxxxxxxxx>

Add the testdebug0/1 clock generators using the osc parent mux.

These may also require PM_DEBUG to work propperly.
Also the parents are - for now - unclear, so we assume osc parents.
