If anyone has any objections, please let me know. ------------------ From: Tony Lindgren [ Upstream commit 2c1593328d7f02fe49de5ad6b42c36296c9d6922 ] Let's create the clock alias based on the clock-output-names property if available. Also the component clock drivers can use ti_dt_clk_name() in the following patches.
