From 8a6389a515f406a89a1a69c267fbc712cdd9e8e9 Mon Sep 17 00:00:00 2001 From: Grygorii Strashko Date: Thu, 6 Jun 2019 19:30:39 +0300 Subject: [PATCH] net: ethernet: ti: cpts: use devm_get_clk_from_child Use devm_get_clk_from_child() instead of devm_clk_get() and this way allow to group CPTS DT properties in sub-node for better code readability and maintenance. Roll-back to devm_clk_get() if devm_get_clk_from_child() fails for backward compatibility. Signed-off-by: Grygorii Strashko Acked-by: Richard Cochran Signed-off-by: David S.
