From: Luo Jie Date: Wed, 5 Jun 2024 12:45:38 +0000 (+0800) Subject: clk: qcom: branch: Add clk_branch2_prepare_ops X-Git-Tag: v6.11-rc1~109^2^2~2^2~19 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7311bbfff31c4961c57d94c165fa843f155f8236;p=thirdparty%2Fkernel%2Flinux.git 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.
