From: Frieder Schrempf <[email protected]>
We have prepared a new driver for the FSL QSPI controller that works under
the SPI framework. The current devicetrees are broken because they use an
inconsistent scheme for assigning the reg properties.
As, in contrast to the current driver, the new driver will use the reg
properties to select the correct chip, we need to fix them.
We also add spi-[tx/rx]-bus-width to make sure the full buswidth will be used
and while at it clean up and remove some unused properties.

The current driver does not use the reg properties, but we will
add a new driver soon. To make sure we have a consistent scheme,
let's fix the reg properties here.

could you please consider these devicetree patches for v4.21?
We have the new FSL QSPI driver under the SPI framework ([1]) ready, but
we need some small fixes to the devicetrees that are currently broken.
As the new driver depends on these changes (mainly the change to the reg
properties) and it is not possible to add compatibility for the old
bindings, it would be really nice to have them in v4.21, so we can queue
the driver for v4.22 or whatever the next release will be called.
Please also see [2] for some more explanation.
Thanks,
Frieder

The properties 'bus-num', 'fsl,spi-num-chipselects' and
'fsl,spi-flash-chipselects' were never read by the driver
and can be removed.

Any chance to get this merged? Otherwise we would need to postpone the
new driver even further.
All the changes to the devicetrees in this series are non-intrusive and
uncritical, anyway.

As it came up a little bit late (the same day I sent pull request for
4.21), I was considering it as 4.22 material. But as you mentioned that
the series is non-intrusive, I can try to send it to arm-soc folk for
4.21 merge window, and then that will be their call. But before I do
it, I need you to double confirm that the series will not break anything
that is already working.
