[PATCH v1 0/5] arm64: dts: imx8mq-librem5: phone description updates

[Martin Kepplinger]

Hi Shawn and all interested,

This is small updates to the Librem 5 phone hardware descriptions we've
been using for quite some time as part of PureOS.

thanks,
                           martin

[PATCH v1 1/5] arm64: dts: imx8mq-librem5: make the volume buttons a wakeup source

[Martin Kepplinger]

They turn on the display currently so to be consistent, let's make
them wake the system from suspend as well.

[PATCH v1 2/5] arm64: dts: imx8mq-librem5: remove description of CHG_STATUS_B

[Martin Kepplinger]

That pin is not connected on the board so no need to describe it.

[PATCH v1 3/5] arm64: dts: imx8mq-librem5: higher boost regulation current

[Martin Kepplinger]

From: Guido Günther <agx@sigxcpu.org>

1,5A is what's used by the type-c controller on the Librem 5 board so
increase ti,boost-max-current to 1,5A too.

[PATCH v1 5/5] arm64: dts: imx8mq-librem5-r4: add the correct panel

[Martin Kepplinger]

From: Guido Günther <agx@sigxcpu.org>

The r4 ("Evergreen") hardware revision of the Librem 5 phone includes a
slightly different panel than the revisions before it. Since its'
description is available, describe it properly for the board.
