firmware: smci: possible NULL dereference

2021-02-03T10:38:41Z

sandbox_scmi_devices_ctx() may return NULL. We should not dereference this value in sandbox_scmi_devices_remove(). The problem was indicated by 'gcc-11 -fanalyzer'. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

dm: Rename DM_GET_DRIVER() to DM_DRIVER_GET()

2021-01-05T19:26:35Z

In the spirit of using the same base name for all of these related macros, rename this to have the operation at the end. This is not widely used so the impact is fairly small. Signed-off-by: Simon Glass

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25Z

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass

dm: core: Rename device_bind_ofnode() to device_bind()

2020-12-13T14:58:18Z

This is the standard function to use when binding devices. Drop the '_ofnode' suffix to make this clear. Signed-off-by: Simon Glass

firmware: zynqmp: Swap addr_hi/low when PM_FPGA_LOAD is called

2020-10-27T07:13:31Z

Don't know reason but in regular flow addr_hi/low are swapped in ATF. It means when fpga load is done from EL3 there is a need to swap it for PMUFW to load bitstream. Signed-off-by: Michal Simek Reviewed-by: Simon Glass

firmware: scmi: Include device_compat.h

2020-10-15T22:36:55Z

This header is necessary for the dev_xxx macros. Signed-off-by: Sean Anderson Reviewed-by: Simon Glass

firmware: smci: sandbox test for SCMI reset controllers

2020-09-30T15:55:24Z

Add tests for SCMI reset controllers. A test device driver sandbox-scmi_devices.c is used to get reset resources, allowing further resets manipulation. Change sandbox-smci_agent to emulate 1 reset controller exposed through an agent. Add DM test scmi_resets to test this reset controller.

reset: add reset controller driver for SCMI agents

2020-09-30T15:55:23Z

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].

firmware: scmi: sandbox test for SCMI clocks

2020-09-30T15:55:23Z

Add tests for SCMI clocks. A test device driver sandbox-scmi_devices.c is used to get clock resources, allowing further clock manipulation. Change sandbox-smci_agent to emulate 3 clocks exposed through 2 agents. Add DM test scmi_clocks to test these 3 clocks. Update DM test sandbox_scmi_agent with load/remove test sequences factorized by {load|remove}_sandbox_scmi_test_devices() helper functions.
