interconnect: imx: set src node

2022-07-15T14:53:15+00:00

When set QoS for a icc path, only set dst icc node is not enough, also need to set src icc node. Signed-off-by: Peng Fan Link: https://lore.kernel.org/r/20220703091132.1412063-6-peng.fan@oss.nxp.com Signed-off-by: Georgi Djakov

interconnect: imx: fix max_node_id

2022-07-15T14:53:04+00:00

max_node_id not equal to the ARRAY_SIZE of node array, need increase 1, otherwise xlate will fail for the last entry. And rename max_node_id to num_nodes to reflect the reality.
