DaVinci: rename gpio_defs.h to gpio.h

2011-08-03T10:49:19+00:00

In preparation for a generic GPIO driver for the DA8xx processors,
rename  to  and fix up all files
which include it.

musb: process control messages after roothub accepted it

2011-06-25T07:53:10+00:00

When dealing with non-multipoint devices, if the software root hub code
accepted the message, then we still need to process it normally.  So only
return quickly when the root hub skipped the message or is otherwise in
an error state.

usb: musb: blackfin: check anomaly workarounds at runtime too

2011-04-02T07:38:24+00:00

The anomaly workarounds we need for older silicon might break things
if used on newer versions where the anomalies don't exist.  So check
the silicon rev at runtime too.

usb: musb: blackfin: make clkin configurable

2011-04-02T07:38:24+00:00

Not everyone has a 24MHz clkin to the USB, so let board porters override.

Switch from archive libraries to partial linking

2010-11-17T20:02:18+00:00

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

usb: musb: constify a bit

usb: musb: only write CLRDATATOG when appropriate

2010-10-13T10:08:43+00:00

This is a change similar to what is already in the Linux driver.  We
should only program the CLRDATATOG bit when the current mode indicates
that it is needed.

usb: musb: stub out MUSB_TXCSR_MODE for Blackfin parts

2010-09-20T19:56:42+00:00

The MUSB_TXCSR_MODE register setting isn't supported on Blackfin musb
parts, so stub it out to 0.  This matches Linux behavior.

usb: musb: setup TXCOUNT for Blackfin musb

2010-09-11T07:49:21+00:00

The Blackfin implementation of musb has a TXCOUNT register that needs to
be programmed when transmitting data.
