2022-03-02clk: scmi: register scmi clocks with CCFEtienne Carriere
Implements SCMI APIs to retrieve the number exposed SCMI clocks using SCMI_PROTOCOL_ATTRIBUTES messages and the names of the clocks using SCMI_CLOCK_ATTRIBUTES messages. This change updates sandbox SCMI clock test driver to manage these 2 new message IDs.

2022-03-02firmware: scmi: fix sandbox and related tests for clock discoveryEtienne Carriere
Updates sandbox SCMI clock driver and tests since enabling CCF will mandate clock discovery that is all exposed SCMI clocks shall be discovered at initialization. For this reason, sandbox SCMI clock driver must emulate all clocks exposed by SCMI server, not only those effectively consumed by some other U-Boot devices. Therefore the sandbox SCMI test driver exposes 3 clocks (IDs 0, 1 and 2) and sandbox SCMI clock consumer driver gets 2 of them.

2022-03-02scmi: change parameter dev in devm_scmi_process_msgEtienne Carriere
Changes devm_scmi_process_msg() first argument from target parent device to current SCMI device and lookup the SCMI agent device among SCMI device parents for find the SCMI agent operator needed for communication with the firmware. This change is needed in order to support CCF in clk_scmi driver unless what CCF will fail to find the right udevice related to exposed SCMI clocks. This patch allows to simplify the caller sequence, using SCMI device reference as parameter instead of knowing SCMI uclass topology. This change also adds some protection in case devm_scmi_process_msg() API function is called for an invalid device type.

Driver should be enabled by CONFIG_POWER_DOMAIN=y and CONFIG_ZYNQMP_POWER_DOMAIN=y. Power domain driver doesn't have own DT node but it uses zynqmp firmware DT node that's why there is a need to bind driver when firmware node is found. Driver itself is simple. It is sending pmufw config object overlay for enabling access to device which is done in ...domain_request(). In ...domain_on() capabilities are passed and node is requested.

2021-11-23firmware: scmi: Add OP-TEE transportEtienne Carriere
This change implements an SCMI transport for agent interfacing the OP-TEE SCMI service. OP-TEE provides an SCMI PTA (Pseudo-TA) for non-secure world to send SCMI messages over an identified channel. The driver implemented here uses a SMT shared memory for passing messages between client and server. The implementation opens and releases channel resources for each passed SCMI message so that resources allocated (sessions) or registered (shared memory areas) in OP-TEE firmware are released for example before relocation as the driver will likely allocate/register them back when probed after relocation. The integration of the driver using dedicated config switch CONFIG_SCMI_AGENT_OPTEE is designed on the model posted to the U-Boot ML by Patrick Delaunay [1].
