From bbde6ebae6dacf2f6e6ac4ab28c1805a2d51c5e1 Mon Sep 17 00:00:00 2001 From: Anand Gadiyar Date: Mon, 24 Aug 2009 17:36:37 +0530 Subject: [PATCH] MUSB: Remove usb_musb_pm_init() call In usb_musb_pm_init, we attempt to access an MUSB register when the i-clock may not be on, or the module is otherwise not accessible. We need to either: - enable the clock before this access, or - remove this code and move it to the bootloader, or - enable the clock in the bootloader If we enable the clock in the bootloader, we might as well add the workaround in the bootloader itself. This code will anyway be changed once hwmod is in place, so remove it for now This allows us to boot the kernel on certain OMAP3 boards with a bootloader that doesn't enable this clock. Without this, we will need to upgrade the bootloaders on these boards.
