Subject: [PATCH] arm64: dts: zynqmp: Add compatible strings for si5328

From: Quanyang Wang <[email protected]>

The function of_i2c_get_board_info will call of_modalias_node to check
if a device_node contains "compatible" string. So let's assign the
proper string "silabs,si5328" to clock-generator@69's compatible
property to eliminate the error info as below:

i2c i2c-10: of_i2c: modalias failure on /axi/i2c@ff030000/i2c-mux@74/i2c@4/clock-generator@69
i2c i2c-10: Failed to create I2C device for /axi/i2c@ff030000/i2c-mux@74/i2c@4/clock-generator@69

Fixes: 82a7ebf00224 ("arm64: dts: zynqmp: Add DT description for si5328 for zcu102/zcu106")

As far as I can tell, "silabs,si5328" isn't documented in
Documentation/devicetree/bindings/. We need DT bindings before making
use of the compatible string.

Thank you for your review.

I will send a new patch to delete these device nodes.

Thank you for your suggestion.

 I will send a new patch to delete these nodes and add some comments there.
