Subject: of/platform: add function to populate default bus
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=43443ad692cf1d41a90cac2ed7066a10cd67a9c6;p=linux-beck.git

of/platform: add function to populate default bus

When a default bus like the simple-bus should be used someone had to
call of_platform_populate() with the default match table. This match
table was not exported, so it is impossible for code build as a module
to use this. Instead of exporting of_default_bus_match_table, add a new
function which uses this default match table and populates the bus.
