labels for the LS connector?

Do you mean arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi

                i2c@78ba000 {
                /* On Low speed expansion */
                        label = "LS-I2C1";
                        status = "okay";
                };

                spi@78b7000 {
                /* On High speed expansion */
                        label = "HS-SPI1";
                        status = "okay";
                };

Thanks

+            compatible = "snps,designware-i2c";
These should have an SoC specific compatible.
We directly use drivers/i2c/busses/i2c-designware-platdrv.c,
do we still an soc specific compatible?
Checked arch/arm64/boot/dts/amd/amd-seattle-soc.dtsi, and other examples,

compatible = "snps,designware-i2c" is used.


Thanks
