[PATCH v3 0/2] Add support for SYSCON reset

WebAIUI, syscon regmaps do not belong to a single device, so calling regmap_attach_dev() seems wrong to me. My (possibly lacking) understanding of the semantics aside, the fact that regmap_attach_dev() is setting fields on the shared regmap without any kind of locking is at least suspicious. rbc freight https://footprintsholistic.com

WebSyscon permits other nodes to access this register space through the regmap mechanism. It is actually just a set of wrapper APIs for regmap. When you request access to syscon, the regmap is created, if it doesn't exist yet. The header required for using the syscon API is . WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
