2012-06-04ARM: OMAP: Make FS USB omap1 onlyTony Lindgren1-145/+0
As the FS USB code is not being actively used for omap2+ there's no point keeping it around for omap2+. Let's make the FS USB platform init code omap1 only so we can remove the last user of omap_read/write for omap2+, and simplify things for further USB, DMA, and device tree related work. While at it, also group the mach includes for the related drivers.

2012-05-11ARM: OMAP: OTG integration: fix compiler warningPaul Walmsley1-1/+3
Tony reported the following compile warning after commit eeb3711b89d68e147e05e7b43a49ecc5009dc157 ("ARM: OMAP2+: clean up some cppcheck warnings"): arch/arm/plat-omap/usb.c: In function 'omap_otg_init': arch/arm/plat-omap/usb.c:40: warning: unused variable 'status' This happens if CONFIG_ARCH_OMAP_OTG is set but CONFIG_USB_GADGET_OMAP, CONFIG_USB_OHCI_HCD, CONFIG_USB_OHCI_HCD_MODULE, and CONFIG_USB_OTG are all unset. Fix by localizing the status variable to the blocks that use it. Compile-tested only, with omap2plus_defconfig and omap2plus_defconfig with CONFIG_USB_OHCI_HCD and CONFIG_USB_OTG enabled.

Thanks to Jarkko Nikula for some comments on the sscanf() warnings. It seems that the kernel sscanf() ignores the field width anyway for the %d format, so those changes have been dropped from this second version.

2012-04-13ARM: OMAP: USB: remove unnecessary sideways includePaul Walmsley1-2/+0
Remove the include of mach-omap2/common.h from plat-omap/usb.c. It appears to be unneeded. Removing it also resolves the sparse warning: arch/arm/plat-omap/../mach-omap2/common.h:183:12: warning: symbol 'omap_intc_of_init' was not declared. Should it be static?

This is needed to minimize io.h so the SoC specific io.h for ARMs can removed. Note that minimal driver changes for DSS and RNG are needed to include cpu.h for SoC detection macros.

2009-12-11omap1: Add omap7xx USB supportCory Maccarrone1-1/+7

2009-11-22omap1: omap_udc: Add clocking and disable vbus sense for omap7xxCory Maccarrone1-6/+14
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.

2009-03-23ARM: OMAP: get rid of OMAP_TAG_USB, v2Felipe Balbi1-21/+4
OMAP_TAGS should vanish soon since they're not generic arm tags. Most of them can be converted to a platform_data or parsed from a command line like e.g. serial tag. For OMAP_TAG_USB we just let boards call omap_usb_init() passing a pointer to omap_usb_config. Patch updated by Tony for mainline, basically make n770 and h4 compile.
