Subject: [PATCH V3] ARM: tegra: paz00: add clocks required for usb operation
Date: Tue, 9 Aug 2011 23:08:11 +0200 [thread overview]
Message-ID: <201108092308.11580.marvin24@gmx.de> (raw)
These clocks are required for usb operation. pll_p_out4 needs to be set
to 24 MHz. The other clocks default to "off" in order to safe some energy.
