Message-ID: <1439308638-14582-20-git-send-email-kishon@ti.com> Date: Tue, 11 Aug 2015 21:27:18 +0530 From: Kishon Vijay Abraham I <kishon@...com> To: <gregkh@...uxfoundation.org> CC: <kishon@...com>, <linux-kernel@...r.kernel.org> Subject: [PATCH 19/19] phy: lpc18xx-usb-otg: fix clock order in phy init From: Joachim Eastwood <manabian@...il.com> Changing the frequency of the USB clock must be done before the PLL is powered on (prepared). This matters when the USB clock is not setup by either boot ROM or boot loader. Reorder the function calls to adhere to the order noted in the user manual.
