2023-08-18mfd: Explicitly include correct DT includesRob Herring1-1/+1
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.

2023-06-15mfd: Switch i2c drivers back to use .probe()Uwe Kleine-König1-1/+1
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.

2023-06-08mfd: rt5033: Fix chip revision readoutJakob Hauser1-2/+3
After reading the data from the DEVICE_ID register, mask 0x0f needs to be applied to extract the revision of the chip [1]. The other part of the DEVICE_ID register, mask 0xf0, is a vendor identification code. That's how it is set up at similar products of Richtek, e.g. RT9455 [2] page 21 top.

2023-06-08mfd: rt5033: Drop rt5033-battery sub-deviceStephan Gerhold1-3/+0
The fuel gauge in the RT5033 PMIC (rt5033-battery) has its own I2C bus and interrupt lines. Therefore, it is not part of the MFD device and needs to be specified separately in the device tree.

2022-12-07mfd: rt5033: Replace irqchip mask_invert with unmask_baseAidan MacDonald1-2/+1
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.

2020-11-27mfd: rt5033: Drop of_match_ptr from of_device_id tableKrzysztof Kozlowski1-1/+1
The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it is not relevant here).

2015-10-26mfd: rt5033: Remove unnecessary MODULE_ALIAS()Javier Martinez Canillas1-1/+0
The driver has a I2C device id table that is used to create the module aliases which already contains a "rt5033". So the alias is not needed. Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2015-08-11mfd: Export OF module alias information in missing driversJavier Martinez Canillas1-0/+1
The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So technically there's no need for a driver to export the OF table since currently it's not used. In fact, the I2C device ID table is mandatory for I2C drivers since a i2c_device_id is passed to the driver's probe function even if the I2C core used the OF table to match the driver. And since the I2C core uses different tables, OF-only drivers needs to have duplicated data that has to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. To avoid the above, the I2C core behavior may be changed in the future to not require an I2C device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table to prevent breaking module autoloading if that happens.
