[PATCH 0/6] ASpeed FSI DT clean-ups

[PATCH 0/6] ASpeed FSI DT clean-ups

[Rob Herring (Arm)]

There's a whole bunch of FSI related DT warnings on ASpeed platforms. 
This series fixes most of them except some related to SBEFIFO.

The remaining SBEFIFO warnings are from some deprecated properties noted 
with 'remove when userspace is fixed'. Not sure if they can be removed 
now or soon. If not, perhaps the deprecated properties need to be 
properly documented.

All the patches here are independent, so DTS changes can go via ASpeed 
tree and FSI bindings via FSI tree (or ack if you want me to take the 
bindings instead).

[PATCH 1/6] ARM: dts: aspeed: Drop "no-gpio-delays"

[Rob Herring (Arm)]

The "no-gpios-delays" property only applies to the "fsi-master-gpio"
binding and not the "aspeed,ast2[45]00-cf-fsi-master" binding. It
doesn't really make sense either as the timing is controlled by the
offloaded firmware.

[PATCH 2/6] ARM: dts: aspeed: Drop "fsi-master" compatibles

[Rob Herring (Arm)]

The "fsi-master" compatible has been used inconsistently on FSI masters.
It doesn't have any real use or meaning, so it's easier to drop it
everywhere than add it where missing. It is also not documented by any
schemas (only .txt bindings).

[PATCH 3/6] ARM: dts: aspeed: Add missing "ibm,spi-fsi" compatibles

[Rob Herring (Arm)]

The "ibm,spi-fsi" compatible is missing or incorrect in various nodes.
The incorrect cases used the "ibm,fsi2spi" compatible by mistake which
is the parent node of the actual SPI controller nodes.
