Subject: net: altera_tse: get numbers of fdt address and size cells
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=75199d6f722a0f711628194240ee5bf724e31101;p=u-boot.git

net: altera_tse: get numbers of fdt address and size cells

Get numbers of fdt address and size cells in altera_tse_probe(),
thereby remove the assumption of one address cell and one size
cell.
