soc: fsl: rcpm: fix missing of_node_put() in copy_ippdexpcr1_setting()

2024-12-05T12:54:22Z

commit c9f1efabf8e3b3ff886a42669f7093789dbeca94 upstream. of_find_compatible_node() requires a call to of_node_put() when the pointer to the node is not required anymore to decrement its refcount and avoid leaking memory. Add the missing call to of_node_put() after the node has been used.

soc: fsl: handle RCPM errata A-008646 on SoC LS1021A

2020-11-24T01:16:02Z

Hardware issue: - Reading register RCPM_IPPDEXPCR1 always return zero, this causes system firmware could not get correct information and wrongly do clock gating for all wakeup source IP during system suspend. Then those IPs will never get chance to wake system. Workaround: - Copy register RCPM_IPPDEXPCR1's setting to register SCFG_SPARECR8 to allow system firmware's psci method read it and do things accordingly.

soc: fsl: add RCPM driver

2019-11-12T21:26:05Z

The NXP's QorIQ processors based on ARM Core have RCPM module (Run Control and Power Management), which performs system level tasks associated with power management such as wakeup source control. Note that this driver will not support PowerPC based QorIQ processors, and it depends on PM wakeup source framework which provide collect wake information.
