If we pass syscon device node itself as first parameter to this function there is no need to parse and find syscon device node. So by allowing "property" parameter as NULL allow syscon_early_regmap_lookup_by_phandle to consider passed argument "np" itself as a syscon device node "syscon_np". This will help us in avoiding addition of "syscon" property which points back to it's own device node in device tree.
Signed-off-by: Pankaj Dubey <pankaj.du...@samsung.com> --- Hello, This patch set depends on early_syscon_initialization patch from Michal Simek [1]. It allows us to call syscon_early_regmap_lookup_by_phandle with NULL property. This is similar change posted here [2] for syscon_regmap_lookup_by_phandle by me.
