mfd: syscon: Don't free allocated name for regmap_config

2020-09-30T15:25:16Z

The name allocated for the regmap_config structure is freed pretty early, right after the registration of the MMIO region. Unfortunately, that doesn't follow the life cycle that debugfs expects, as it can access the name field long after the free has occurred. Move the free on the error path, and keep it forever otherwise. Fixes: e15d7f2b81d2 ("mfd: syscon: Use a unique name with regmap_config") Signed-off-by: Marc Zyngier Signed-off-by: Lee Jones

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

mfd: syscon: Use a unique name with regmap_config

2020-08-13T06:51:03Z

The DT node full name is currently being used in regmap_config which in turn is used to create the regmap debugfs directories. This name however is not guaranteed to be unique and the regmap debugfs registration can fail in the cases where the syscon nodes have the same unit-address but are present in different DT node hierarchies. Replace this logic using the syscon reg resource address instead (inspired from logic used while creating platform devices) to ensure a unique name is given for each syscon.

mfd: syscon: Add arguments support for syscon reference

2020-01-24T07:33:59Z

There are a lot of similar global registers being used across multiple SoCs from Unisoc. But most of these registers are assigned with different offset for different SoCs. It is hard to handle all of them in an all-in-one kernel image. Add a helper function to get regmap with arguments where we could put some extra information such as the offset value.

mfd: syscon: Re-use resource_size() to count max_register

2020-01-24T07:33:56Z

Instead of open coded variant use resource_size() and replace weird '- 3' to more understandable '- 4'. Signed-off-by: Andy Shevchenko Acked-by: Arnd Bergmann Signed-off-by: Lee Jones

Revert "mfd: syscon: Set name of regmap_config"

2019-11-13T11:07:40Z

This reverts commit 500f9ff518cf55930c670b0e2b8901caf70a7548. The original commit is a duplication of the exactly previously added commit 408d1d570a63 ("mfd: syscon: Set regmap name to DT node name"). Revert the unnecessary later one. Signed-off-by: Andy Shevchenko Signed-off-by: Lee Jones

mfd/syscon: Add device_node_to_regmap()

2019-08-08T22:30:07Z

device_node_to_regmap() is exactly like syscon_node_to_regmap(), but it does not check that the node is compatible with "syscon", and won't attach the first clock it finds to the regmap. The rationale behind this, is that one device node with a standard compatible string "foo,bar" can be covered by multiple drivers sharing a regmap, or by a single driver doing all the job without a regmap, but these are implementation details which shouldn't reflect on the devicetree.

2019-06-24T03:22:30Z

Nobody uses the exported helper syscon_regmap_lookup_by_pdevname, to lookup a device by name. Let us remove it. Suggested-by: Arnd Bergman Cc: Arnd Bergman Cc: Greg Kroah-Hartman Cc: "Rafael J. Wysocki" Signed-off-by: Suzuki K Poulose Signed-off-by: Greg Kroah-Hartman
