The GPIO mappings on the IQS variant differ from the CQ variants.
GPIO138 is connected to the RGMII1_RX_CTL pin rather than the NFC ESE
Secure IO pin; the latter is connected to GPIO49. This incorrect
reservation causes the probe of the second Ethernet port to fail:

  shikra-tlmm 500000.pinctrl: error -EINVAL: pin-138 (5d20000.ethernet)
  shikra-tlmm 500000.pinctrl: error -EINVAL: could not request pin 138
  (GPIO_138) from group gpio138 on device 500000.pinctrl
  qcom-ethqos 5d20000.ethernet: Error applying setting, reverse things back

Apply this patch and reproduce it. Is is possible? Didn't we talk about
this already?

Replace gpio138 with gpio49 in the reserved list.

This looks duplicating:

Ah, no, mixed patches. Duplication is between other works:
https://lore.kernel.org/all/20260820085347.822-1-xueyao.an@oss.qualcomm.com/ (local)
https://lore.kernel.org/all/20260826-shikra-dtpm-v4-1-8476223184de@oss.qualcomm.com/ (local)

But nevertheless I am sure we talked about this, that commit msg and is
not accurate... Cannot find the thread, though...

Yes, I'll reword the commit message so it reads as a prerequisite for
enabling Ethernet rather than implying a current break. Also, the Fixes:
needs to be dropped as mentioned by Andrew.
