mfd: Remove unused helper syscon_regmap_lookup_by_pdevname

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

mfd: syscon: Add optional clock support

2019-05-14T07:13:25Z

Some system control registers need to be clocked, so the registers can be accessed. Add an optional clock and attach it to regmap. Signed-off-by: Fabrice Gasnier Acked-by: Arnd Bergmann Signed-off-by: Lee Jones

mfd: syscon: Make it explicitly non-modular

2019-02-01T08:21:13Z

The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_SYSCON drivers/mfd/Kconfig: bool "System Controller Register R/W Based on Regmap" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init was not in use by this code, the init ordering remains unchanged with this commit. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

mfd: syscon: Set name of regmap_config

2018-05-16T08:21:48Z

We are now allowing to register debugfs without a valid device, and not having a valid name will end up using "dummy*" to create debugfs dir. Signed-off-by: Jeffy Chen Signed-off-by: Lee Jones

mfd: syscon: Set regmap name to DT node name

2018-05-16T08:21:48Z

This sets the regmap name to the device tree node name. This is useful for debugging. Signed-off-by: David Lechner Acked-by: Arnd Bergmann Signed-off-by: Lee Jones

mfd: syscon: Add hardware spinlock support

2018-01-12T18:32:55Z

Some system control registers need hardware spinlock to synchronize between the multiple subsystems, so we should add hardware spinlock support for syscon. Signed-off-by: Baolin Wang Acked-by: Rob Herring Acked-by: Lee Jones Signed-off-by: Mark Brown

mfd: syscon: Support native-endian regmaps

2016-11-25T10:04:31Z

The regmap devicetree binding documentation states that a native-endian property should be supported as well as big-endian & little-endian, however syscon in its duplication of the parsing of these properties omits support for native-endian. Fix this by setting REGMAP_ENDIAN_NATIVE when a native-endian property is found.

mfd: syscon: Make syscon_regmap_config const

2016-03-16T08:50:18Z

syscon_regmap_config can be made const if syscon_probe() creates a local copy on the stack, just like syscon_register() does. Signed-off-by: Philipp Zabel Signed-off-by: Lee Jones

mfd: syscon: Set regmap max_register in of_syscon_register
