The content dm_ofnode_pre_reloc() is identical with ofnode_pre_reloc() defined in drivers/core/ofnode.c and used only three times: - drivers/core/lists.c:lists_bind_fdt() - drivers/clk/at91/pmc.c::at91_clk_sub_device_bind - drivers/clk/altera/clk-arria10.c::socfpga_a10_clk_bind

So this function dm_ofnode_pre_reloc can be removed and replaced by these function calls by ofnode_pre_reloc().

Signed-off-by: Patrick Delaunay patrick.delaunay@st.com --- Hi Simon,

It is a rebased patch for http://patchwork.ozlabs.org/patch/1035799/ marked as superseded but never resent (and I forget it).

Compilation is OK on travis: https://travis-ci.org/github/patrickdelaunay/u-boot/builds/670029232

Patrick

Changes in v2: - rebase on master - udpate dm_ofnode_pre_reloc call in at91_clk_sub_device_bind and socfpga_a10_clk_bind
