      omap1: omap_udc: Add clocking and disable vbus sense for omap7xx · 45f780a0
      由 Cory Maccarrone 提交于 
      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.

      USB: fsl_udc_core: Fix kernel oops on module removal · 37c4fd8c
      由 Anton Vorontsov 提交于 
      fsl_udc_release() calls dma_free_coherent() with an inappropriate
device passed to it, and since the device has no dma_ops, the following
oops pops up:

This patch fixes the issue by passing dev->parent, which points to
a correct device.

      ARM: Fix lubbock defconfig build · 09963911
      由 Russell King 提交于 
      drivers/built-in.o: In function `pxa25x_udc_probe':
drivers/usb/gadget/pxa25x_udc.c:2195: undefined reference to `otg_get_transceiver'
drivers/usb/gadget/pxa25x_udc.c:2300: undefined reference to `otg_put_transceiver'

pxa25x_udc.c unconditionally uses these two functions, so we need to
ensure that the object providing them is also built.

      omap: headers: Move remaining headers from include/mach to include/plat · ce491cf8
      由 Tony Lindgren 提交于 
      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 $headers; do
	old="#include <mach\/$header"
	new="#include <plat\/$header"
	for dir in $omap_dirs; do
		find $dir -type f -name \*.[chS] | \
			xargs sed -i "s/$old/$new/"
	done
	find drivers/ -type f -name \*omap*.[chS] | \
		xargs sed -i "s/$old/$new/"
	for file in $other_files; do
		sed -i "s/$old/$new/" $file
	done
done

for header in $(ls $mach_dir_old/*.h); do
	git mv $header $plat_dir_new/
done

      usb: r8a66597-udc unaligned fifo fix · 59c82d12
      由 Magnus Damm 提交于 
      Rework the r8a66597-udc fifo code to avoid unaligned accesses.

Without this patch unaligned exceptions will degrade the
USB performance. The exceptions come from the fact that
the usb fifo data buffers may be misaligned.

This patch updates the fifo access code to only use
insl()/outsl() and insw()/outsw() in the case of properly
aligned data buffers. The fallback case is that inl()/inw()
are used for misaligned buffer reads together with outb()
that is used for misaligned buffer writes.
