Hi Martin
I don't think this is the reason. I think historically stmmac messed
up and ignored the flags. There are a number of device tree blobs
which have the incorrect flag value, but since it was always ignored,
it did not matter. Then came along a board which really did need the
flag, but it was too late, it could not be enabled because too many
boards would break. So the hack was made, and snps,reset-active-low
was added.
Since snps,reset-active-low is a hack, it should not be in the
core. Please don't add it to gpiolib-of.c, keep it within stmmac
driver.
