[PATCH v2 00/16] Cleanup of LS1021a device trees

[Li Yang]

This is a series of patches trying to cleanup the LS1021a based device
trees including:
- Add missing nodes
- Update to use SPDX tags
- Fix existing schema check issues in dts
- Update related bindings to deal with some check issues

Changes in V2
- Spin-off the IFC binding related patches into a separate series due to
  its dependency on driver changes
- Added two more fixes about thermal-zones node and flash compatible
- Remove copyright updates
- Updated description in i2c binding patch to clarify the intension
- Added Acked-by tag

[PATCH v2 02/16] dt-bindings: i2c: imx: update schema to align with original txt binding

[Li Yang]

When the binding was converted from txt to yaml, it actually added more
constrains than the original txt binding which was already used in many
in-tree DTSes.  Some of the newly added constrains are either not valid
or not neccessary.

Not all SoCs use ipg as the clock name for i2c.  There is no point in
having SoC integration information defined in i2c binding.  Remove the
clock name requirement in the schema.

The original txt binding didn't require the order of tx and rx for
dmas/dma-names.  Many in tree DTSes are already using the other order.
Both orders should just work fine.  Update the schema to allow both.

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

IMO, both of these should be fixed in the dts files.

Any name you want is not fine. Your choices are remove clock-names,
add all the names used, or change everyone to use 'ipg'.

Doesn't sound like a case where defining the order is challenging.

I understand that the name should be important as clocks are
referenced by name.  But since the i2c controller only has one clock ,
the name is never referenced in the driver.

If we really want to define the name, IMO, it should be from the
perspective of the i2c controller like "clkin" or "i2c" instead of the
"ipg" from the perspective of SoC integration which could be changing
with a different integration.  I can list both "i2c" and "ipg" for now
as a workaround though.

No, it is not challenging.  But as dma channel is only referenced by
name instead of index.  I don't see too much benefit in enforcing the
order other than easier to create the schema.

the name is never referenced in the driver.

If we really want to define the name, IMO, it should be from the
perspective of the i2c controller like "clkin" or "i2c" instead of the
"ipg" from the perspective of SoC integration which could be changing
with a different integration.  I can list both "i2c" and "ipg" for now
as a workaround though.

No, it is not challenging.  But as dma channel is only referenced by
name instead of index.  I don't see too much benefit in enforcing the
order other than easier to create the schema.

Then just remove 'clock-names' from the dts file.

$modulename for $foo-names always looks made up and pointless to me.

Easier is nice, and that's the 'DT way' is the other reason.

Had thought the clock-names are mandatory, but it turns out not.
Removing it should be great.

Can we have flash chip name instead of qflash?
There is no hard requirement, it will help in aligning node properties with other board properties such as LX2160A-RDB, LS1046A-RDB etc.

[PATCH v2 09/16] ARM: dts: ls1021a: remove regulators simple-bus

[Li Yang]

There is no regulator bus in hardware.  So move the regulator nodes out
and remove the regulators simple-bus.  This also make the dts align with
the simple-bus schema.

[PATCH v2 13/16] ARM: dts: ls1021a-qds: change fpga to simple-mfd device

[Li Yang]

The FPGA is not really a bus but more like an MFD device.  Change the
compatible string from "simple-bus" to "simple-mfd".  This also fix a
node name issue with simple-bus schema.

[PATCH v2 16/16] ARM: dts: ls1021a-tsn: use generic "jedec,spi-nor" compatible for flash

[Li Yang]

We cannot list all the possible chips used in different board revisions,
just use the generic "jedec,spi-nor" compatible instead.  This also
fixes dtbs_check error:
['s25fl256s1', 's25fl512s', 'jedec,spi-nor'] is too long
