[PATCH 8/8] clk: bcm2835: add the testdebug clock generators
kernel at martin.sperl.org
kernel at martin.sperl.org
Mon Feb 29 07:44:02 PST 2016
From: Martin Sperl <kernel at martin.sperl.org>
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.
Signed-off-by: Martin Sperl <kernel at martin.sperl.org>
