Hi NXP,
I wish i can use internel pll clock with pcie, so I follow up this post to change SCFW and device-tree.
https://community.nxp.com/t5/i-MX-Processors/imx8q-PCIE-internal-clock-master/m-p/1155340
But still got error message like below, here is my dts pcie setting, is there anything I missied?
&pcieb{
compatible = "fsl,imx8qxp-pcie","snps,dw-pcie";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_pcieb>;
disable-gpio = <&max7311 0 GPIO_ACTIVE_LOW>;
reset-gpio = <&lsio_gpio4 0 GPIO_ACTIVE_LOW>;
// clkreq-gpio = <&lsio_gpio4 1 GPIO_ACTIVE_LOW>;
ext_osc = <0>;
status = "okay";
};
