of: create of_phandle_args to simplify return of phandle parsing data
of_parse_phandle_with_args() needs to return quite a bit of data. Rather than making each datum a separate **out_ argument, this patch creates struct of_phandle_args to contain all the returned data and reworks the user of the function. This patch also enables of_parse_phandle_with_args() to return the device node pointer for the phandle node. This patch also ends up being fairly major surgery to of_parse_handle_with_args(). The existing structure didn't work well when extending to use of_phandle_args, and I discovered bugs during testing. I also took the opportunity to rename the function to be like the existing of_parse_phandle(). v2: - moved declaration of of_phandle_args to fix compile on non-DT builds - fixed incorrect index in example usage - fixed incorrect return code handling for empty entries Reviewed-by: Shawn Guo <shawn.guo@freescale.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
