dt-bindings: Fix incorrect 'reg' property sizes

2020-05-14T19:43:27+00:00

The examples template is a 'simple-bus' with a size of 1 cell for
had between 2 and 4 cells which really only errors on I2C or SPI type
devices with a single cell.

The easiest fix in most cases is to change the 'reg' property to for 1 cell
address and size. In some cases with child devices having 2 cells, that
doesn't make sense so a bus node is needed.

dt-bindings: interconnect: Add bindings for imx8m noc

2020-04-28T17:03:02+00:00

Add initial dt bindings for the interconnects inside i.MX chips.
Multiple external IPs are involved but SOC integration means the
software controllable interfaces are very similar.

Main NOC node acts as interconnect provider if #interconnect-cells is
present. Currently there is a single imx interconnect provider for the
whole SOC.

Other pieces of scalable interconnects can be present, each with their
own OPP table.

dt-bindings: Clean-up schema indentation formatting

2020-04-16T21:59:22+00:00

Fix various inconsistencies in schema indentation. Most of these are
list indentation which should be 2 spaces more than the start of the
enclosing keyword. This doesn't matter functionally, but affects running
scripts which do transforms on the schema files.
