The latest kernel I could find on this board was a TI BSP based v3.14 kernel. So I had to port these patches to that kernel. Cc Robert Nelson to see if he knows about a more recent kernel supporting that cape. I did not see any breakage with these patches applied although I did not see any noticeable performance improvement as well. I also tested along with continuous loop reading from /sys/bus/iio/devices/iio:device0/in_voltage5_raw I have pushed the kernel I used here in case anyone wants to take a look at my porting. http://git.ti.com/cgit/cgit.cgi/~nsekhar/ti-linux-kernel/nsekhar-ti-linux-kernel.git/log/?h=am335x-tsc-test I also tested this series on AM335x EVM using the v3.18-rc5 kernel. Again, no breakage but no improvement as well. All testing was done using ts_test FWIW, you can add: Tested-by: Sekhar Nori <nsekhar@xxxxxx> Thanks, Sekhar -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
