kernel/linux.git/drivers/usb/dwc2/debugfs.c, branch v4.4.8Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v4.4.82015-09-27T15:54:31+00:00usb: dwc2: Use platform endianness when accessing registers2015-09-27T15:54:31+00:00Antti Seppäläa.seppala@gmail.com2015-08-20T18:41:07+00:00urn:sha1:95c8bc3609440af5e4a4f760b8680caea7424396
This patch switches calls to readl/writel to their
dwc2_readl/dwc2_writel equivalents which preserve platform endianness.
This patch is necessary to access dwc2 registers correctly on big-endian
systems such as the mips based SoCs made by Lantiq. Then dwc2 can be
used to replace ifx-hcd driver for Lantiq platforms found e.g. in
OpenWrt.
The patch was autogenerated with the following commands:
$EDITOR core.h
sed -i "s/\<readl\>/dwc2_readl/g" *.c hcd.h hw.h
sed -i "s/\<writel\>/dwc2_writel/g" *.c hcd.h hw.h
Some files were then hand-edited to fix checkpatch.pl warnings about
too long lines.

this driver has long ago became dwc2.ko with
both peripheral and host roles, there's no point
in keeping the old function names.

usb: dwc2: remove dwc2_platform.ko2015-04-29T20:20:11+00:00Mian Yousaf Kaukabyousaf.kaukab@intel.com2015-04-29T20:09:18+00:00urn:sha1:2d1165a4b95e25aed83fed737d53ab0c87b831e6
As dwc2 pci module is now exporting dwc2 platform device, include
platform.o in dwc2-y and remove USB_DWC2_PLATFORM configuration
option. Driver will be built as two modules, dwc2.ko and dwc2_pci.ko.
dwc2.ko is the new platform driver.
Remove all EXPORT_SYMBOL_GPL as they are not needed any more.

Dump all registers to take a complete snapshot of dwc2 state.
Code is inspired by dwc3/debugfs.c

Prepare to add more debug code. Moreover, don't save dentry * for
each file in struct dwc2_hsotg as clean up is done with
debugfs_remove_recursive(). s3c_hsotg_delete_debug() is removed
altogether for the same reason.
