Hi Timur,
you are right ,the QE can not support the 36-bit , I test it on
the p1025 ,the qe can not work
but we need the qe node , becase the dts include the
fsl/p1021si-post.dtsi
that needed, I will send other patch
My suggestion: with a 36-bit device tree, the QE must be disabled.
qe: qe@fffe80000 {
/* The QE does not work with 36-bit addressing */
status = "disabled";
};
However, on the P102x, there may be a GUTS register that stores the upper
four bits of the QE's physical address. Your patch *can* work if you
*also* set this register to 0xF. Look for that register.
