For the series, Reviewed-by: Siddharth Vadapalli <s-vadapalli@ti.com> Since DT and driver patches go to different subsystems, both patches need to go in simultaneously to avoid making devices non-functional if one of the patches gets applied but the other one doesn't. Regards, Siddharth.
From: Francesco Dolcini <francesco.dolcini@toradex.com> Fix PCIe PERST# signal polarity in TI J721E used on TI K3 machines. PCIe PERST# needs to be de-asserted for PCIe to work, however, the driver is doing the opposite and the device tree files are defining the signal with the wrong polarity to cope with that. Fix both the driver and the affected DT files.
