Best practice for spidev in devicetree

[Patrick Menschel <menschel.p@xxxxxxxxx>]

Hello,

I need guidance towards best practice in defining a spidev device in a 
devicetree.

I came up with

https://github.com/beagleboard/BeagleBoard-DeviceTrees/pull/67/commits/ef496f62e7df60513ffa6cb01b5bb383718dcd05

+&spi1 {
+       status = "okay";
+       pinctrl-names = "default";
+       pinctrl-0 = <&spi1_pins>;
+
+       channel@0 {
+               /* external S1.0 connector JST-SH 6pin */
+               compatible = "spidev";
+               reg = <0>;
+       };
+
+       channel@1 {
+               /* external S1.1 connector JST-SH 6pin */
+               compatible = "spidev";
+               reg = <1>;
+       };
+};
.
Means I leave the original spi1 driver alone and set the channels to 
"spidev", yet

https://www.kernel.org/doc/html/latest/spi/spidev.html

says, it's discouraged while keeping silent about what is to be done in 
a device tree.

Thank you.

Best Regards,
Patrick Menschel
