2021-03-30	reset: reset-scmi: Port driver to the new scmi_reset_proto_ops interface	Cristian Marussi	1	-13/+20
	Port the scmi reset driver to the new SCMI reset interface based on protocol handles and common devm_get_ops().

2019-12-24	reset: reset-scmi: Match scmi device by both name and protocol id	Sudeep Holla	1	-1/+1
	The scmi bus now has support to match the driver with devices not only based on their protocol id but also based on their device name if one is available. This was added to cater the need to support multiple devices and drivers for the same protocol. Let us add the name "reset" to scmi_device_id table in the driver so that in matches only with device with the same name and protocol id SCMI_PROTOCOL_RESET.

2019-09-18	reset: reset-scmi: add missing handle initialisation	Sudeep Holla	1	-0/+1
	scmi_reset_data->handle needs to be initialised at probe, so that it can be later used to access scmi reset protocol APIs using the same. Since it was tested with a module that obtained handle elsewhere, it was missed easily. Add the missing scmi_reset_data->handle initialisation to fix the issue.

2019-08-12	reset: Add support for resets provided by SCMI	Sudeep Holla	1	-0/+124
	On some ARM based systems, a separate Cortex-M based System Control Processor(SCP) provides the overall power, clock, reset and system control. System Control and Management Interface(SCMI) Message Protocol is defined for the communication between the Application Cores(AP) and the SCP. Adds support for the resets provided using SCMI protocol for performing reset management of various devices present on the SoC. Various reset functionalities are achieved by the means of different ARM SCMI device operations provided by the ARM SCMI framework.
