arm64: dts: imx95-19x19-evk: correct the phy setting for flexcan1/2
1, the phy support up to 8Mbit/s databitrate for CAN FD. refer to product data sheet: https://www.nxp.com/docs/en/data-sheet/TJA1463.pdf 2, the standby pin of the phy is ACTIVE_LOW. 3, the phy of flexcan2 connect the standby/en pin to PCAL6408 on i2c4 bus. Fixes: 02b7adb ("arm64: dts: imx95-19x19-evk: add adc0 flexcan[1,2] i2c[2,3] uart5 spi3 and tpm3") Signed-off-by: Haibo Chen <[email protected]> Reviewed-by: Frank Li <[email protected]> Signed-off-by: Shawn Guo <[email protected]>
