From c0aefc75ce2512bc308a89ca3cb7bece63c1128f Mon Sep 17 00:00:00 2001 From: Boris BREZILLON Date: Fri, 2 Aug 2013 10:37:34 +0200 Subject: [PATCH] usb: gadget: at91_udc: add usb_clk for transition to common clk framework The AT91 PMC (Power Management Controller) provides an USB clock used by USB Full Speed host (ohci) and USB Full Speed device (udc). The usb drivers (ohci and udc) must configure this clock to 48Mhz. This configuration was formely done in mach-at91/clock.c, but this implementation will be removed when moving to common clk framework. This patch adds support for usb clock retrieval and configuration, and is backward compatible with the current at91 clk implementation (if usb clk is not found, it does not configure/enable it).
