mfd: Explicitly include correct DT includes

2023-08-18T20:48:03Z

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: mt6397: Add basic support for MT6331+MT6332 PMIC

2022-07-19T09:54:41Z

Add support for the MT6331 PMIC with MT6332 Companion PMIC, found in MT6795 Helio X10 smartphone platforms. This combo has support for multiple devices but, for a start, only the following have been implemented: - Regulators (two instances, one in MT6331, one in MT6332) - RTC (MT6331) - Keys (MT6331) - Interrupts (MT6331 also dispatches MT6332's interrupts) There's more to be implemented, especially for MT6332, which will come at a later stage.

mfd: mt6397-core: Add resources for PMIC keys for MT6359

Add the MFD resources in order to be able to probe and use the keyboard driver for the MT6359 PMIC. Signed-off-by: Fabien Parent Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20220415153629.1817202-4-fparent@baylibre.com

mfd: mt6397: Add PMIC keys for MT6358

2021-06-02T09:49:59Z

Add compatible strings and interrupts for pmic keys which serves as child device of MFD. MT6358 has two interrupts per key: one for press, another one for release (_R) Signed-off-by: Mattijs Korpershoek Signed-off-by: Lee Jones

mfd: mt6397: Use named IRQs instead of index (keys)

2021-06-02T09:49:59Z

Some pmics of the mt6397 family (such as MT6358), have two IRQs per physical key: one for press event, another for release event. The mtk-pmic-keys driver assumes that each key only has one IRQ. The key index and the RES_IRQ resource index have a 1/1 mapping. This won't work for MT6358, as we have multiple resources (2) for one key. To prepare mtk-pmic-keys to support MT6358, retrieve IRQs by name instead of by index. Note: The keys_resources are not part of the device-tree bindings so this won't break any DT schemas.

mfd: Add support for the MediaTek MT6359 PMIC

2021-06-01T15:44:23Z

This adds support for the MediaTek MT6359 PMIC. This is a multifunction device with the following sub modules: - Codec - Interrupt - Regulator - RTC It is interfaced to the host controller using SPI interface by a proprietary hardware called PMIC wrapper or pwrap. MT6359 MFD is a child device of the pwrap. Signed-off-by: Hsin-Hsiung Wang Signed-off-by: Lee Jones

mfd: mt6397: Drop of_match_ptr from of_device_id table

2020-11-27T08:01:54Z

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). This fixes compile warning (!CONFIG_OF on x86_64): drivers/mfd/mt6397-core.c:214:34: warning: ‘mt6397_of_match’ defined but not used [-Wunused-const-variable=] Signed-off-by: Krzysztof Kozlowski Signed-off-by: Lee Jones

mfd: mt6397: Trim probe function to support different chips more cleanly

2020-05-21T07:54:57Z

Add new struct members for mfd-cells and irq initial function, so we can call devm_mfd_add_devices() only once. Signed-off-by: Hsin-Hsiung Wang Signed-off-by: Lee Jones
