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

Commit Message

Martin Sperl Feb. 29, 2016, 3:44 p.m. UTC

From: Martin Sperl <[e-mail]>

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.
