Changes are made to the existing DA9063 OnKey component so that functionality in this device driver can be re-used to support the DA9062 OnKey. This following patch set is the proposed method for re-using the existing kernel OnKey drivers for chips whose OnKey blocks are functionally similar to the DA9063 OnKey. The main points for the MFD core and device tree changes are as follows. - Alteration of the DA9063 OnKey Kconfig needs to be updated to depend on both MFD_DA9063 "or" MFD_DA9062. There is no explicit DA9062 OnKey Kconfig. - The DA9062 MFD core should add a new OnKey resource as usual and an entry in the mfd_cell to support a component name and of_compatible for "da9062-onkey" and "dlg,da9062-onkey". - The device tree binding support should include a compatible string for "dlg,da9062-onkey" The main points for the OnKey changes are as follows: A generic structure is used (called da9063_compatible_onkey_regmap) to hold all generic registers and bitmasks for use with this type of OnKey component. Functions in the DA9063 OnKey will be refactored to use this compatibility struct and all accesses to generic registers/masks will be made through this table look-up instead of using defines from the register header files directly Linkage between the DA9062 MFD and the DA9063 OnKey driver is created through the use of an of_match_table entry in the platform_driver structure. A re-work of da9063_onkey_probe() is necessary to use the of_match_node() and dev_get_regmap() functions: this will provide initialisation of the generic registers and masks and allow access to the regmap according to the correct device tree specification. The addition of a of_device_id table for DA9063 and DA9062 default data is created.
