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

mfd: mt6397: Modify suspend/resume behavior

2020-05-21T07:54:40Z

Some pmics don't need backup interrupt settings, so we change to use pm notifier for the pmics which are necessary to store settings. Signed-off-by: Hsin-Hsiung Wang Signed-off-by: Lee Jones

mfd: mt6397: Use PLATFORM_DEVID_NONE macro instead of -1

2019-11-11T08:45:02Z

Use the correct macro when adding the MFD devices instead of using directly '-1' value. Signed-off-by: Fabien Parent Reviewed-by: Matthias Brugger Signed-off-by: Lee Jones
