[PATCH v3 0/4] Correct vendor-prefix and document device isl29028

[Darshana Padmadas]

Patchset documents correct and the deprecated vendor-prefix found by checkpatch 
warning and also documents information of device isl29028 for compatibility. 
Patchset also includes corrected vendor-prefix and device name in compatible 
property for files with checkpatch warning of undocumented string "isil,isl29028".

  Documentation: devicetree: bindings: Document correct and deprecated
    vendor-prefix with device isl29028
  Documentation: devicetree: bindings: Document deprecated device vendor
    name to fix related warning
  Staging: iio: light: Added correct vendor-prefix for device isl29028
  arch: arm: boot: dts: Added correct vendor-prefix with device name to
    compatible property  
  
Changes in v3: 
    - In PATCH 1/4 corrected alphabetical order of vendor-prefix and device name. 
    - In PATCH 2/4 inserted deprecated vendor-prefix in list in alphabetical order 
      and edited vendor/chip string. 
    - In PATCH 4/4 dropped deprecated string "isil,isl29028" and included correct 
      vendor-prefix isl with isl29028 to give "isl,isl29028" for device's compatible 
      property.

Looking again, could you change the comment to "(deprecated, use isl)",
as I mentioned previously?

Then that will match what we have for powervr, which seems to be the
only other instance of "deprecated" in vendor-prefixes.txt.

Cheers,
Mark.

Does this intentionally list only the new string?

If we want compatibility between new dts files and old kernels, this would
need to be 

	compatible = "isl,isl29028", compatible = "isil,isl29028";

I don't know if we want to go that far though, given that this is
only a staging driver.

Are we aiming for new dts wto work with old kernels? It's nice if they
do, but I don't think it should be necessary. Old DTBs should definitely
work with a new kernel, though.

Personally I'd rather see one string (preferably the canonical one, but
the deprecated one is ok) than two strings when those strings are for
the exact same device.
