From ce491cf85466c3377228c5a852ea627ec5136956 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Tue, 20 Oct 2009 09:40:47 -0700 Subject: omap: headers: Move remaining headers from include/mach to include/plat Move the remaining headers under plat-omap/include/mach to plat-omap/include/plat. Also search and replace the files using these headers to include using the right path. This was done with: #!/bin/bash mach_dir_old="arch/arm/plat-omap/include/mach" plat_dir_new="arch/arm/plat-omap/include/plat" headers=$(cd $mach_dir_old && ls *.h) omap_dirs="arch/arm/*omap*/ \ drivers/video/omap \ sound/soc/omap" other_files="drivers/leds/leds-ams-delta.c \ drivers/mfd/menelaus.c \ drivers/mfd/twl4030-core.c \ drivers/mtd/nand/ams-delta.c" for header in $headers; do old="#include --- drivers/usb/gadget/omap_udc.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'drivers/usb/gadget/omap_udc.c') diff --git a/drivers/usb/gadget/omap_udc.c b/drivers/usb/gadget/omap_udc.c index a2db0e174f2c..b836efe9ea71 100644 --- a/drivers/usb/gadget/omap_udc.c +++ b/drivers/usb/gadget/omap_udc.c @@ -52,9 +52,9 @@ #include #include -#include -#include -#include +#include +#include +#include #include "omap_udc.h" -- cgit v1.2.3 From 45f780a06153544ab84fd1da3a8b28c07f61da1d Mon Sep 17 00:00:00 2001 From: Cory Maccarrone Date: Sun, 22 Nov 2009 10:10:52 -0800 Subject: omap1: omap_udc: Add clocking and disable vbus sense for omap7xx The l3_ocpi_ck clock is needed on omap7xx processors for USB. Additionally, bit 8 of the SOFT_REQ_REG needs to be enabled for the usb_dc_ck on omap7xx, which is a different bit than that of the omap16xx-defined clock of the same name. I added a provision for the usb_dc_ck and l3_ocpi_ck clocks as dc_clk and hhc_clk, respectively, for omap7xx CPUs. Additionally, I added a check in machine_without_vbus_sense for all omap7xx devices, as presently I know of no omap7xx-based devices that have vbus sense, and it made more sense to me to use a cpu check here than to spell out each machine one at a time. Finally, DMA is disabled for omap7xx, as it causes problems with these chips.
