lib: utils/reset: Try initializing all reset devices in dt

2024-06-13T16:18:03Z

In DT, multiple reset devices may use the same driver, and they may have different priorities. If rc is returned after the first initialization, the highest priority device may be lost.

lib: utils/reset: Fix fdt_reset to search for more dt nodes

2024-06-13T13:19:51Z

If there are multiple dt nodes, the previous code only tries to match the first one, which may lose initialization. Signed-off-by: Xiang W Reviewed-by: Anup Patel

utils/reset: Remove fdt_reset_thead

2023-11-16T10:55:23Z

In the past, we used fdt_reset_thead to help customers with prototype verification. However, with the emergence of the Big-little SoC system, it can no longer meet the demand. Therefore, we use zero_stage_boot instead of fdt_reset_thead. It cleans up the opensbi code and ends the disputation of reset_sample's dts. This patch removes the fdt_reset_thead component and updates the related doc. Signed-off-by: Guo Ren Signed-off-by: Guo Ren Reviewed-by: Anup Patel
