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.
