From 7311bbfff31c4961c57d94c165fa843f155f8236 Mon Sep 17 00:00:00 2001 From: Luo Jie Date: Wed, 5 Jun 2024 20:45:38 +0800 Subject: [PATCH] clk: qcom: branch: Add clk_branch2_prepare_ops Add the clk_branch2_prepare_ops for supporting clock controller where the hardware register is accessed by MDIO bus, and the spin lock can't be used because of sleep during the MDIO operation. The clock is enabled by the .prepare instead of .enable when the clk_branch2_prepare_ops is used.
