[PATCH v6 0/6] Add MediaTek PMIC keys support

[PATCH v6 0/6] Add MediaTek PMIC keys support

[Chen Zhong]

MediaTek PMIC are multi-function devices that can handle key interrupts, typically there are two keys attached to PMIC, which called pwrkey and homekey. PWRKEY usually used to wake up system from sleep. Homekey can used as volume down key due to board design. Long press keys can shutdown PMIC, the mode can be choose to be one key only or two keys together.
This series add support for key functions for MediaTek PMIC MT6397/MT6323.

Changes since v5:
- use __maybe_unused annotation instead of #ifdef guard
- use of_* API instead of device_* API

Changes since v4:
- rebase to Linux 4.14-rc1
- add a common keyboard binding document
- use child device tree node to define each key

Changes since v3:
- make the naming to be consistent as mtk_pmic or MTK_PMIC
- add suspend/resume functions to enable/disable irq
- change binding properties to define wakeup sources

Changes since v2:
- use standard properties for keycodes and debounce time
- change to use platform_get_irq in leaf drivers
- use better ways to define IRQ resources

Changes since v1:
- create irq mappings in mfd core driver instead of leaf drivers
- remove some unused parts in mtk-pmic-keys driver

[PATCH v6 1/6] mfd: mt6397: create irq mappings in mfd core driver

[Chen Zhong]

The core driver should create and manage irq mappings instead of
leaf drivers. This patch change to pass irq domain to
devm_mfd_add_devices() and it will create mapping for irq resources
automatically. And remove irq mapping in rtc driver since this has
been done in core driver.

This patch adds compatible strings and interrupts for pmic keys
which serves as child device of MFD.

Re: [PATCH v6 0/6] Add MediaTek PMIC keys support

[Sean Wang]

Hi, Dmitry and Lee

The series seems not being got merged. Are they good enough to be ready
into the your tree?

Recently I've tested the series with focusing on pwrkey event generated
through interrupt when push and release the key on bpi-r2 board and then
finally it's working fine. but for homekey it cannot be found on the
board and thus I cannot have more tests more about it.

You have my Ack on the input patch; I expect it go through Lee's tree as
there are some dependencies on mfd core piece.

Thanks.

Thanks Matthias, Lee, Dmitry and Sean for your comments.

Hi Lee,

I have collected the Acks by Rob and sent the v6:
https://patchwork.kernel.org/patch/10026705
https://patchwork.kernel.org/patch/10026707

Are they enough to be merged?

Thank you.

Oh, sorry, I did not realize you wanted my Ack for bindings. I usually

I'll go and add my ack to the binding post if that will help merging

Thanks.
