mfd: MAX8997/8966 support MAX8997/MAX8966 chip is a multi-function device with I2C bussses. The chip includes PMIC, RTC, Fuel Gauge, MUIC, Haptic, Flash control, and Battery (charging) control. This patch is an initial release of a MAX8997/8966 driver that supports to enable the chip with its primary I2C bus that connects every device mentioned above except for Fuel Gauge, which uses another I2C bus. The fuel gauge is not supported by this mfd driver and is supported by a seperated driver of MAX17042 Fuel Gauge (yes, the fuel gauge part is compatible with MAX17042).

mfd: max8997: Make it explicitly non-modular The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_MAX8997 drivers/mfd/Kconfig: bool "Maxim Semiconductor MAX8997/8966 PMIC Support" ...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. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_init was not in use by this code, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. 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: core: Push irqdomain mapping out into devices Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.

mfd: MAX8997/8966 support MAX8997/MAX8966 chip is a multi-function device with I2C bussses. The chip includes PMIC, RTC, Fuel Gauge, MUIC, Haptic, Flash control, and Battery (charging) control. This patch is an initial release of a MAX8997/8966 driver that supports to enable the chip with its primary I2C bus that connects every device mentioned above except for Fuel Gauge, which uses another I2C bus. The fuel gauge is not supported by this mfd driver and is supported by a seperated driver of MAX17042 Fuel Gauge (yes, the fuel gauge part is compatible with MAX17042).

mfd: max8997: Make it explicitly non-modular The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_MAX8997 drivers/mfd/Kconfig: bool "Maxim Semiconductor MAX8997/8966 PMIC Support" ...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. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_init was not in use by this code, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.
