Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] The device tree fails to configure the Bluetooth reset and wake pins documented in the commit message, leaving the inherited Bluetooth node broken.
- [Low] The commit message contains a copy-paste error in its hardware differences table headers.

commit 92706a692f2e24d9485918053962b1a10410a0ca
Author: Joseph Guo <qijian.guo@nxp.com>

arm64: dts: imx93: Add i.MX93 Wireless FRDM board support

This adds support for the i.MX93 Wireless FRDM board, reusing the
imx93-11x11-frdm-common.dtsi with board-specific changes. It updates pin
connections and functionality differences, mainly for WIFI/BT and I2C3.

> Pin connection differences:
> Function  Signal name   i.MX93W EVK             i.MX93 EVK

[Severity: Low]
This isn't a bug, but there's a copy-paste error in the table headers.
Should these be FRDM-IMX93W and FRDM-IMX93 instead of EVK?

[Severity: Medium]
Does this board-specific device tree need to include node overrides for
&bluetooth to configure the reset and wake pins documented in the commit
message?

The commit message notes that IND_RST_NB uses GPIO_IO28 (which was freed up
by rerouting I2C3), but there is no &bluetooth node override assigning it to
reset-gpios. Could this leave the inherited Bluetooth peripheral in reset
and broken?
