2012-08-07gpio: samsung: Fix off-by-one bug in gpio addressesSean Paul
Move gpc4 to the end of the automatically processed gpio controllers so we don't taint the automatic offset calculation. This bug caused all controllers coming after gpc4 to map to the incorrect address. The result is <&gpd1 0 0 0 0> would actually map to GPIO 0 in gpd0.

2012-08-07ARM: dts: imx: add alias for gpioShawn Guo
Add alias for gpio nodes, so that gpio driver can identify the port number and then specify a sensible gpio base rather than using the one dynamically allocated by gpio core. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2012-08-07gpio/mxc: specify gpio base for device tree probeShawn Guo
Currently, unlike the non-DT probe where the gpio base is specified with pdev->id, the DT probe uses the base dynamically allocated by gpio core, which uses a completely different numbering scheme. This causes two issues to user space applications which access sysfs entry /sys/class/gpio/gpioN. * It breaks the compatibility with user space applications between non-DT and DT kernels. * It's not intuitive and sometimes hard for users to map the Linux gpio number to the actual hardware pin. Use alias to identify the gpio port/bank, and then the gpio base can be specified with port id to solve above issues. If alias is not defined in device tree, the base number dynamically allocated by gpio core will be used.

2012-08-06mwifiex: improve scan delay logic during Tx trafficAmitkumar Karwar
Earlier scan command was postponed by 20msec multiple times to give preference to Tx traffic until we find empty wmm queue. There is a corner case in which wmm queue becomes empty immediately after processing the packet(before 20msec) and there may be next packet coming after some time. In this case we should not resume scan operation. We will use new flag to check Tx traffic and resume scan operation only if there is no traffic for 200msec.
