Hi Mike, After merging the clk tree, today's linux-next build (x86_64 allmodconfig) failed like this: ERROR: "of_clk_add_provider" [drivers/clk/clk-si5351.ko] undefined! ERROR: "of_clk_src_onecell_get" [drivers/clk/clk-si5351.ko] undefined! ERROR: "__clk_get_flags" [drivers/clk/clk-si5351.ko] undefined! Caused by commit 9abd5f0555df ("clk: add si5351 i2c common clock driver"). It probbaly need to depend on CONFIG_OF. I have used the clk tree from next-20130412 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
