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.

The handle_irq_event_* functions are expected to be called with interrupts disabled and they rightfully complain here because we run in tasklet context with interrupts enabled.

2020-08-13mfd: madera: Improve handling of regulator unbindingCharles Keepax1-8/+15
The current unbinding process for Madera has some issues. The trouble is runtime PM is disabled as the first step of the process, but some of the drivers release IRQs causing regmap IRQ to issue a runtime get which fails. To allow runtime PM to remain enabled during mfd_remove_devices, the DCVDD regulator must remain available. In the case of external DCVDD's this is simple, the regulator can simply be disabled/put after the call to mfd_remove_devices. However, in the case of an internally supplied DCVDD the regulator needs to be released after the other MFD children depending on it. Use the new MFD mfd_remove_devices_late functionality to split the DCVDD regulator off from the other drivers.

2020-08-13mfd: mfd-core: Add mechanism for removal of a subset of childrenCharles Keepax1-1/+15
Currently, the only way to remove MFD children is with a call to mfd_remove_devices, which will remove all the children. Under some circumstances it is useful to remove only a subset of the child devices. For example if some additional clean up is required between removal of certain child devices. To accomplish this a level field is added to mfd_cell, the normal mfd_remove_devices is modified to not remove devices that are set to a higher level and a corresponding mfd_remove_devices_late function is added to remove those children.

2020-08-13mfd: da9063: Add support for latest DA silicon revisionAdam Thomson1-10/+81
This update adds new regmap tables to support the latest DA silicon which will automatically be selected based on the chip and variant information read from the device. Signed-off-by: Adam Thomson <Adam.Thomson.Opensource@diasemi.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2020-08-13mfd: da9063: Fix revision handling to correctly select reg tablesAdam Thomson2-48/+167
The current implementation performs checking in the i2c_probe() function of the variant_code but does this immediately after the containing struct has been initialised as all zero. This means the check for variant code will always default to using the BB tables and will never select AD. The variant code is subsequently set by device_init() and later used by the RTC so really it's a little fortunate this mismatch works. This update adds raw I2C read access functionality to read the chip and variant/revision information (common to all revisions) so that it can subsequently correctly choose the proper regmap tables for real initialisation.
