mfd: Switch i2c drivers back to use .probe()

2023-06-15T08:19:37+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

mfd: max77693: Replace irqchip mask_invert with unmask_base

2022-12-07T13:28:14+00:00

Remove use of the deprecated mask_invert flag. Inverted mask registers (where a '1' bit enables an IRQ) can be described more directly as an unmask register.

i2c: Make remove callback return void

2022-08-16T10:46:26+00:00

The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

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
