Subject: usb: ehci-omap: update clock names to be more generic
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6dba39e278b81665a838f37a75fe37b89f3ce610;p=openwrt%2Fstaging%2Fblogic.git

usb: ehci-omap: update clock names to be more generic

Rename usbhost2_120m_fck to usbhost_hs_fck and usbhost1_48m_fck
to usbhost_fs_fck, to better reflect the clocks' functionalities.

In OMAP4, the frequencies for the corresponding clocks are not
necessarily the same as with OMAP3, however the functionalities
are.
