I cannot see the point of struct pruss_priv, I think it would be better to
just merge the two data structures into one. Everything else looks
good to me now.

pruss_priv is needed to get access to uio_pruss_dev from uio_info *info in
UIO interrupt handler (pruss_handler) and shall be per interrupt entry.

+static irqreturn_t pruss_handler(int irq, struct uio_info *info) {
+	struct pruss_priv *priv = info->priv;
+	struct uio_pruss_dev *gdev = priv->pupdev;

Note that info is a pointer to array supporting 8 interrupts. This allows to
redirect to driver structure via info->priv quickly.

Thanks,
