This series being tested on da850 EVM. Tested by setting VPIF_DOUT[12] as GPIO pin [2] and reading GPIO status from GPIO[7,4] GPIO[7,4] will reflect the status switch number 8 of the S7 dip switch in DA850 EVM. Testing Procedure Requirement GPIO SYSFS support [1] #echo 116 > /sys/class/gpio/export setting GPIO[7,4] as input GPIO #echo "in" > /sys/class/gpio/gpio116/direction #mount -t debugfs debugfs /sys/kernel/debug Reading GPIO pin status #cat /sys/kernel/debug/gpio #echo 116 > /sys/class/gpio/unexport 1. Enable GPIO SYSFS support through menconfig --- GPIO Support [ ] Debug GPIO calls [ ] /sys/class/gpio/... (sysfs interface) 2. Patch for pinmux support for GPIO[7,4] is available at https://github.com/avinashphilip/am335x_linux/commits/linux_davinci_v3.10_soc_gpio Thanks Avinash > > Thanks, > Sekhar > ????{.n?+???????+%?????ݶ??w??{.n?+????{??G?????{ay?ʇڙ?,j??f???h?????????z_??(?階?ݢj"???m??????G????????????&???~???iO???z??v?^?m???? ????????I?
