[PATCH v6 0/9] mfd: max8997: Add regmap support

From: Krzysztof Kozlowski
Date: Fri May 06 2016 - 03:22:04 EST


This is a rebase and extension of old Robert Baldyga's work. [0]

Robert no longer works in Samsung.

>From the original cover letter:
"This patchset modifies max8997 driver and associated function drivers to use
register maps instead of operating directly on i2c bus. This change allowed
to simplify irq handling, and to move some initializations to individual
function drivers. Hence now when some functions are not enabled, their i2c
clients, regmaps and irqs are not registered."

My changes (since Robert's v5)
1. Rebase on v4.6-rc6.
2. Collect more acks.
3. Add few fixes:
a. Haptic fix from Marek,
b. Extcon and RTC fix from me,
c. DTS fixes from Marek.

DTS changes are independent but rest of them (extcon/input/MFD) rely
on each other.

One way of merging would be to pick everything (except DTS) through
one tree. Or use tags.

Best regards,
