* [PATCH v10 1/5] staging: hikey9xx: split hi6421v600 irq into a separate driver
2021-06-29 10:31 [PATCH v10 0/5] Move Hisilicon 6421v600 SPMI and USB drivers out of staging Mauro Carvalho Chehab

Per MFD subsystem requirements, split the IRQ part of the
driver into a separate one with just the IRQ handling code
and the powerkey support.

platform drvdata can't be used inside the regulator driver,
as this is already used by the MFD and SPMI drivers.
So, change the logic to allocate it inside the
struct hi6421_spmi_pmic.
While here, drop the now unused struct and add a missing dot
at the Huawei's copyrights.
Fixes: 50e629362e1f ("regulator: hi6421v600: Fix setting wrong driver_data")

- Add support for HiSilicon Hi6421v600 SPMI PMIC. Hi6421 includes
- multi-functions, such as regulators, RTC, codec, Coulomb counter,
- etc.
-
- This driver includes core APIs _only_. You have to select
- individual components like voltage regulators under corresponding
- menus in order to enable them.
- We communicate with the Hi6421v600 via a SPMI bus.
