From 5411bad4ea16622d4204dc590567000b194e5cc2 Mon Sep 17 00:00:00 2001 From: David Lechner Date: Fri, 18 May 2018 11:48:13 -0500 Subject: ARM: davinci: da8xx: add new USB PHY clock init using common clock framework This adds the new USB PHY clock init in mach-davinci/usb-da8xx.c using the new common clock framework drivers. The #ifdefs are needed to prevent compile errors until the entire ARCH_DAVINCI is converted.
