interconnect: imx: Fix return value check in imx_icc_node_init_qos()

2020-05-10T15:30:37Z

In case of error, the function of_parse_phandle() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.

interconnect: Add imx core driver

2020-04-28T17:03:02Z

This adds support for i.MX SoC family to interconnect framework. Platform drivers can describe the interconnect graph and several adjustment knobs where icc node bandwidth is converted to a DEV_PM_QOS_MIN_FREQUENCY request. The interconnect provider is probed through the main NOC device and other adjustable nodes on the same graph are found from a fsl,scalable-nodes phandle array property.
