mfd: max8997: Simplify obtaining I2C match data and drop max8997_i2c_get_driver_data()

2023-11-01T10:02:09+00:00

Simplify probe() by using i2c_get_match_data() instead of max8997_i2c_get_driver_data() for retrieving match data from OF/ID tables. Signed-off-by: Biju Das Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20230828160224.92037-1-biju.das.jz@bp.renesas.com Signed-off-by: Lee Jones

mfd: Explicitly include correct DT includes

2023-08-18T20:48:03+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

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: max8997: Convert to i2c's .probe_new()

2022-12-07T13:27:23+00:00

.probe_new() doesn't get the i2c_device_id * parameter, so determine that explicitly in the probe function. Signed-off-by: Uwe Kleine-König Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20221118224540.619276-445-uwe@kleine-koenig.org

mfd: max8997: Simplify getting of_device_id match data

2021-06-02T09:51:17+00:00

Use of_device_get_match_data() to make the code slightly smaller. There is also no need to wrap it in a check for CONFIG_OF, because dev.of_node will be set only with OF support. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Lee Jones

Revert "mfd: max8997: Add of_compatible to Extcon and Charger mfd_cell"

2021-04-14T15:06:53+00:00

This reverts commit 9c03008da125c1007919a9186628af3cc105f526. commit 41a8a027f4d3 ("regulator: dt-bindings: Document charger-supply for max8997") introduced a binding which uses a property of the max8997 pmic node to configure charger supply, making subnodes for MFD cells obsolete.

mfd: max8997: Add of_compatible to Extcon and Charger mfd_cell

2021-02-08T13:54:09+00:00

Add of_compatible ("maxim,max8997-muic") to the mfd_cell to have a of_node set in the extcon driver. Add of_compatible ("maxim,max8997-battery") to the mfd_cell to configure the charger driver. Signed-off-by: Timon Baetz Reviewed-by: Krzysztof Kozlowski Signed-off-by: Lee Jones

mfd: max8997: Convert to i2c_new_dummy_device

2019-08-12T07:53:58+00:00

Move from i2c_new_dummy() to i2c_new_dummy_device(), so we now get an ERRPTR which we use in error handling. Signed-off-by: Wolfram Sang Signed-off-by: Lee Jones

mfd: max8997: Disable interrupt handling for suspend/resume cycle

2018-10-23T07:58:34+00:00

Disable IRQs during suspend/resume cycle to ensure handling of wakeup interrupts (i.e. RTC wake alarm) after max8997_resume(). This way it can be properly handled when I2C bus is finally available. This pattern is also used in other MAX PMIC MFD drivers. Signed-off-by: Marek Szyprowski Reviewed-by: Krzysztof Kozlowski Signed-off-by: Lee Jones

mfd: max8997: Enale irq-wakeup unconditionally

2018-10-23T07:58:34+00:00

IRQ wake up support for MAX8997 driver was initially configured by respective property in pdata. However, after the driver conversion to device-tree, setting it was left as 'todo'. Nowadays most of other PMIC MFD drivers initialized from device-tree assume that they can be an irq wakeup source, so enable it also for MAX8997. This fixes support for wakeup from MAX8997 RTC alarm.
