mfd: syscon: Include linux/err.h to fix build error

2014-06-03T07:11:41Z

commit df73de9b0d412 ("mfd: syscon: Return -ENOSYS if CONFIG_MFD_SYSCON is not enabled") introduced fallbacks for APIs, but missed out on adding the header file. This would work only if linux/err.h is also included in the source code from where this file is included. It would be better to include linux/err.h in file to remove possible build errors. Without this patch, we get following and similar build errors if this header file is included in some source file and CONFIG_MFD_SYSCON is not enabled. include/linux/mfd/syscon.h: In function ‘syscon_node_to_regmap’: include/linux/mfd/syscon.h:30:2: error: implicit declaration of function ‘ERR_PTR’ [-Werror=implicit-function-declaration] return ERR_PTR(-ENOSYS); ^ include/linux/mfd/syscon.h:30:18: error: ‘ENOSYS’ undeclared (first use in this function) return ERR_PTR(-ENOSYS); ^ Signed-off-by: Tushar Behera Signed-off-by: Lee Jones

Some platforms may not define CONFIG_MFD_SYSCON (or haven't syscon), it can fix build error for these platforms. Signed-off-by: Peter Chen Signed-off-by: Lee Jones

mfd: syscon: Add missing struct device_node declaration

2013-04-09T09:52:32Z

syscon.h header uses struct device_node in functions' declarations without declaring it. This causes compilation warnings like: include/linux/mfd/syscon.h:20: warning: ‘struct device_node’ declared inside parameter list include/linux/mfd/syscon.h:20: warning: its scope is only this definition or declaration, which is probably not what you want Fix it by adding a forward declaration of struct device_node.

mfd: syscon: Add non-DT support

2013-04-05T15:58:22Z

This patch allow using syscon driver from the platform data, i.e. possibility using driver on systems without oftree support. For search syscon device from the client drivers, "syscon_regmap_lookup_by_pdevname" function was added. Signed-off-by: Alexander Shiyan Acked-by: Arnd Bergmann Signed-off-by: Samuel Ortiz

mfd: Add syscon driver based on regmap

2012-09-17T13:24:14Z

Add regmap based syscon driver. This is usually used for access misc bits in registers which does not belong to a specific module, for example, IMX IOMUXC GPR and ANATOP. With this driver, client can use generic regmap API to access registers which are registered into syscon.
