[PATCH v3 0/1] orange-pi-zero: minor updates for peripherals

[Sergey Matyukevich]

This patch adds optional node for SPI NOR chip on the orange-pi-zero board.

Changes from v2:
- add new node in alphabetical order
- drop changes for wifi xr819 node for the time being:
  -- more work is needed, e.g. adding bindings for XR819

Changes from v1:
- update commit messages: drop links to wiki at linux-sunxi.org
- disable SPI NOR flash by default
- drop description of the flash partitions
- add compatible property for XR819 wifi node

[PATCH v3 1/1] ARM: dts: orange-pi-zero: add node for SPI NOR

[Sergey Matyukevich]

Add node for SPI NOR flash on orange-pi-zero board. Disable this node
by default and leave it to users to enable it if their board has
SPI NOR flash chip populated.

SPI NOR flash was optional in the first production batch in Dec 2016.
In later batches flash chip was pre-populated. However there should
be quite a few boards around which do not have flash chip.
