Subject: ARM: ux500: assign the sensor trigger IRQs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=22a93167025b2b4ae4476bc01645dccb96ff0742;p=linux.git

ARM: ux500: assign the sensor trigger IRQs

The ST sensors on the Ux500 boards were not utilizing the IRQs
for data ready sample triggers. Enable this by assigning the
right GPIO lines and interrupt lines (when the GPIO lines are
used for IRQs) to the accelerometer, gyro and magnetometer
sensors.
