2020-09-30sntp: use udp frameworkPhilippe Reynes
This commits update the support of sntp to use the framework udp. This change allows to remove all the reference to sntp in the main network file net/net.c. Signed-off-by: Philippe Reynes <[email protected]> Reviewed-by: Simon Glass <[email protected]>
2020-09-30net: add a generic udp protocolPhilippe Reynes
This commit adds a generic udp protocol framework in the network loop. So protocol based on udp may be implemented without modifying the network loop (for example custom wait magic packet). Signed-off-by: Philippe Reynes <[email protected]> Reviewed-by: Simon Glass <[email protected]>
2020-09-30reset: add reset controller driver for SCMI agentsEtienne Carriere
This change introduces a reset controller driver for SCMI agent devices. When SCMI agent and SCMI reset domain drivers are enabled, SCMI agent binds a reset controller device for each SCMI reset domain protocol devices enabled in the FDT. SCMI reset driver is embedded upon CONFIG_RESET_SCMI=y. If enabled, CONFIG_SCMI_AGENT is also enabled. SCMI Reset Domain protocol is defined in the SCMI specification [1].

2020-09-30firmware: add SCMI agent uclassEtienne Carriere
This change introduces SCMI agent uclass to interact with a firmware using the SCMI protocols [1]. SCMI agent uclass currently supports a single method to request processing of the SCMI message by an identified server. A SCMI message is made of a byte payload associated to a protocol ID and a message ID, all defined by the SCMI specification [1]. On return from process_msg() method, the caller gets the service response. SCMI agent uclass defines a post bind generic sequence for all devices. The sequence binds all the SCMI protocols listed in the FDT for that SCMI agent device. Currently none, but later change will introduce protocols. This change implements a simple sandbox device for the SCMI agent uclass. The sandbox nicely answers SCMI_NOT_SUPPORTED to SCMI messages. To prepare for further test support, the sandbox exposes a architecture function for test application to read the sandbox emulated devices state. Currently supports 2 SCMI agents, identified by an ID in the FDT device name. The simplistic DM test does nothing yet. SCMI agent uclass is designed for platforms that embed a SCMI server in a firmware hosted somewhere, for example in a companion co-processor or in the secure world of the executing processor. SCMI protocols allow an SCMI agent to discover and access external resources as clock, reset controllers and more. SCMI agent and server communicate following the SCMI specification [1]. This SCMI agent implementation complies with the DT bindings defined in the Linux kernel source tree regarding SCMI agent description since v5.8.

2020-09-30regmap: Add support for regmap fieldsJean-Jacques Hiblot
A regmap field is an abstraction available in Linux. It provides to access bitfields in a regmap without having to worry about shifts and masks. Signed-off-by: Jean-Jacques Hiblot <[email protected]> Reviewed-by: Simon Glass <[email protected]> Signed-off-by: Pratyush Yadav <[email protected]>
2020-09-30regmap: Allow devices to specify regmap range start and size in configPratyush Yadav
Some devices need to calculate the regmap base address at runtime. This makes it impossible to use device tree to get the regmap base. Instead, allow devices to specify it in the regmap config. This will create a regmap with a single range that corresponds to the start and size given by the driver.

2020-09-30regmap: Add regmap_init_mem_range()Pratyush Yadav
Right now, the base of a regmap can only be obtained from the device tree. This makes it impossible for devices which calculate the base at runtime to use a regmap. An example of such a device is the Cadence Sierra PHY. Allow creating a regmap with one range whose start and size can be specified by the driver based on calculations at runtime.

2020-09-30regmap: Allow specifying read/write widthPratyush Yadav
Right now, regmap_read() and regmap_write() read/write a 32-bit value only. To write other lengths, regmap_raw_read() and regmap_raw_write() need to be used. This means that any driver ported from Linux that relies on regmap_{read,write}() to know the size already has to be updated at each callsite. This makes the port harder to maintain. So, allow specifying the read/write width to make it easier to port the drivers, since now the only change needed is when initializing the regmap.

2020-09-30dm: Print device name in dev_xxx like LinuxSean Anderson
This adorns messages generated by dev_xxx with the device and driver names. It also redirects dev_xxx to log when it is available. The names of these functions very roughly take inspiration from Linux, but there is no deeper correlation. Both struct udevice and struct device are supported when logging, though logging with struct device is no better than using log_xxx. The latter is supported because of the large amount of existing code which logs with struct device. Signed-off-by: Sean Anderson <[email protected]> Tested-by: Patrick Delaunay <[email protected]>
