iio: imu: adis16480: sync upstream & re-add prod_id reg#834
Merged
Conversation
In function adis16480_ext_clk_config(), the ADIS16480_DRDY_SEL macro is used to get the number of the pin. In the ADI version, it's done via explicit masking. This change syncs to upstream. Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com>
Was removed by accident during initial sync with upstream. Fixes: 58cc06d ("iio: imu: adis16136,16400,16480: sync with upstream") Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com>

On the preemption path when updating a Xen guest's runstate times, this lock is taken inside the scheduler rq->lock, which is a raw spinlock.

This changeset syncs a change from upstream. It was done differently in the ADI tree for the pin check.
And re-adds the prod_id reg back. Was removed by accident in #827
