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
