Re: [OpenWrt-Devel] [PATCH] ramips/rt305x: Add I2C gpio platform data.
Hi Tobias,
i have been working on an update to ramips the last weeks, which bumps
the kernel tot the upstream OF enabled one. This update will superseed
your patch. we are currently not merging any patches based on the old
code pattern.
i will try to make an image for you to test using a devicetree with the
i2c-gpio driver enabled and i2c-tools added if that is ok.

[OpenWrt-Devel] [PATCH] [generic] Add port mirroring/monitoring capability to AR8327 switch driver
Hi,
this patch adds the swlib attributes
enable_mirror_rx
enable_mirror_tx
mirror_monitor_port
mirror_source_port
to the AR8327 switch/PHY driver that allow to mirror Ethernet packets to a
monitor port.
Tested on a TL-WDR4300 router.

[OpenWrt-Devel] [PATCH] iputils: replace busybox symlinks for commands arping/ping/ping6 when installing the corresponding iputils alternatives
Add preinst/postrm hooks to iputils, so that there are no install-time
conflicts,
either when opkg installing, or embedding in a binary.
Symlink is restored on package removal.

This fixes this error: root@6470028f4363:~# opkg install iputils-arping_20101006-1_ar71xx.ipk Installing iputils-arping (20101006-1) to root... Installing libsysfs (2.1.0-2) to root...

Collected errors: * check_data_file_clashes: Package iputils-arping wants to install file /usr/bin/arping But that file is already provided by package * busybox * opkg_install_cmd: Cannot install package iputils-arping. And in addition smooths out the install of ping/ping6, which currently give no errors, but /bin/ping6 is preferred by $PATH, so this patch disables that feature-less busybox version right away, giving a streamlined experience (?) like the following: root@6470028f4363:~# ping6 BusyBox v1.19.4 (2013-03-30 05:23:56 ART) multi-call binary.

On my Ubuntu 12.04 system, /usr/bin/ccache was getting picked up as the compiler under race-y conditions, and then cmake would try to run /usr/bin/ccache ccache_cc causing the compilation to fail with a ccache invoked recursively error.

Awesome. Device trees are a nice step forward from specific
mach-files I think. :)
i will try to make an image for you to test using a devicetree with

Sure, thanks.
Ideally you could add the INA2XX module, since that is what I have
hooked up on the bus.
