2021-06-02mfd: arizona: Allow building arizona MFD-core as moduleHans de Goede
There is no reason why the arizona core,irq and codec model specific regmap bits cannot be build as a module. All they do is export symbols which are used by the arizona-spi/i2c and arizona-codec modules, which themselves can be built as module. Change the Kconfig and Makefile arizona bits so that the arizona MFD-core can be built as a module. This is especially useful on x86 platforms with a WM5102 codec, this allows the arizona MFD driver necessary for the WM5102 codec to be enabled in generic distro-kernels without growing the base kernel-image size. Note this also adds an explicit "depends on MFD_ARIZONA" to all the arizona codec Kconfig options. The codec drivers use functions from mfd arizona-core. These new depends are necessary to disallow the codec drivers being builtin when the arizona-core is build as a module, otherwise we end up with missing symbol errors when building vmlinuz.

2021-06-02mfd: axp20x: Allow AXP 806 chips without interrupt linesAndre Przywara
Currently the AXP chip requires to have its IRQ line connected to some interrupt controller, and will fail probing when this is not the case. On a new Allwinner SoC (H616) there is no NMI pin anymore, and at least one board does not connect the AXP's IRQ pin to anything else, so the interrupt functionality of the AXP chip is simply not available. Check whether the interrupt line number returned by the platform code is valid, before trying to register the irqchip. If not, we skip this registration, to avoid the driver to bail out completely. Also we need to skip the power key functionality, as this relies on a valid IRQ as well. Signed-off-by: Andre Przywara <andre.przywara@arm.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2021-06-02mfd: mt6397: Use named IRQs instead of index (keys)Mattijs Korpershoek
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.
