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.
