This patch series adds support for the brand new Raspberry Pi 3 A+ .
Since there is no official DTS file yet, this one bases on a procfs dump and
the dt-blob of the firmware [1].
[1] - https://github.com/raspberrypi/firmware/blob/master/extra/dt-blob.dts
Changes in V4:
- address Phil's comment by dropping BT_ON and rename WL_ON to BT_WL_ON
- drop Wifi and BT reset control and add explaining comment
- add missing gpio line names
- add Rob's Reviewed-by
Changes in V3:
- add Eric's Reviewed-by
- fix wifi reset GPIO polarity
Changes in V2:
- add missing Makefile change for arm64

The Raspberry Pi 3 A+ is similar to the Pi 3 B+ but has only 512 MB RAM,
1 USB 2.0 port and no Ethernet.
Compared to the Raspberry Pi 3 B it isn't possible to control BT_ON and
WL_ON separately.

This adds a reference to the dts of the Raspberry Pi 3 A+,
so we don't need to maintain the content in arm64.

Hi, Stefan,
is this patch the only update required to run Rpi3 A+ with kernel 4.20?
Thank you,
Sergey
