I suggest just sync imx53.dtsi from the linux-next, as a result we will have
non-modified version of kernel templates.
Change as above, makes imx53.dtsi different for kernel and barebox.
This is part of sata node from the kernel:
sata: sata@10000000 {
compatible = "fsl,imx53-ahci";
reg = <0x10000000 0x1000>;
interrupts = <28>;
clocks = <&clks IMX5_CLK_SATA_GATE>,
<&clks IMX5_CLK_SATA_REF>,
<&clks IMX5_CLK_AHB>;
clock-names = "sata_gate", "sata_ref", "ahb";
status = "disabled";
};
