Switch the XTAL32 configuration from Kconfig to devicetree Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>
This oscillator has better accuracy and is available by default on this board. Disable this in the ethernet variant where XTAL32 is disconnected so we can use the ethernet pins. Signed-off-by: Mahesh Mahadevan <mahesh.mahadevan@nxp.com>

@mmahadevan108 ,
i guess &xtal32 node needs add and enable in ubx_evk_iris_w1_common.dtsi ?

I did not enable it in the dtsi as by default xtal32 is not connected and requires a hardware modification.
This what I read on Page 24 of this document: https://content.u-blox.com/sites/default/files/documents/EVK-IRIS-W1_UserGuide_UBX-23007837.pdf .
Please correct me if I am missing something.

Hi @mmahadevan108 ,
You’re correct — the 32 kHz crystal isn’t populated by default, so leaving xtal32 disabled in the DTSI is appropriate.
XTAL32 Kconfig was always turned on when using the RTC 1Hz block which is incorrect. This should be dependent on whether this oscillator is enabled to be used.
