From cfdc0411cf01aff7bb44a4edcbaa578ad363ab77 Mon Sep 17 00:00:00 2001 From: Dong Aisheng Date: Fri, 31 Aug 2018 12:45:53 +0800 Subject: clk: bulk: add of_clk_bulk_get() 'clock-names' property is optional in DT, so of_clk_bulk_get() is introduced here to handle this for DT users without 'clock-names' specified. Later clk_bulk_get_all() will be implemented on top of it and this API will be kept private until someone proves they need it because they don't have a struct device pointer.
