mfd: max77693: Do not enforce (incorrect) interrupt trigger type

2021-11-05T14:40:06+00:00

Interrupt line can be configured on different hardware in different way, even inverted. Therefore driver should not enforce specific trigger type - edge falling - but instead rely on Devicetree to configure it. The Maxim 77693 datasheet describes the interrupt line as active low with a requirement of acknowledge from the CPU therefore the edge falling is not correct. The interrupt line is shared between PMIC and RTC driver, so using level sensitive interrupt is here especially important to avoid races. With an edge configuration in case if first PMIC signals interrupt followed shortly after by the RTC, the interrupt might not be yet cleared/acked thus the second one would not be noticed.

mfd: max77693: Allow building as a module

2016-04-19T06:53:52+00:00

The consumer of max77693 regulators on Trats2 board (samsung-usb2-phy driver) supports deferred probing so the max77693 main MFD driver can be built now as a module. This gives more flexibility and removes manual ordering of init calls. Suggested-by: Paul Gortmaker Signed-off-by: Krzysztof Kozlowski Signed-off-by: Lee Jones

drivers: max77693: Move state container to common header

2015-07-16T20:39:30+00:00

This prepares for merging some of the drivers between max77693 and max77843 so the child MFD driver can be attached to any parent MFD main driver. Move the state container to common header file. Additionally add consistent 'i2c' prefixes to its members (of 'struct i2c_client' type).
