https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-3.1.y2008-06-10T15:39:13Zpowerpc/QE: add support for QE USB clocks routing2008-06-10T15:39:13ZAnton Vorontsov2008-05-23T16:38:56Zurn:sha1:5e41486c408eb4206aee09303631427f57771691
This patch adds a function to the qe_lib to setup QE USB clocks routing.
To setup clocks safely, cmxgcr register needs locking, so I just reused
ucc_lock since it was used only to protect cmxgcr.
The idea behind placing clocks routing functions into the qe_lib is that
later we'll hopefully switch to the generic Linux Clock API, thus, for
example, FHCI driver may be used for QE and CPM chips without nasty #ifdefs.
This patch also fixes QE_USB_RESTART_TX command definition in the qe.h.
