Add initial support for new target with the initial patch for ethernet support using pending upstream patches for PCS UNIPHY, PPE and EDMA. Only initramfs currently working as support for new SPI/NAND implementation, USB, CPUFreq and other devices is still unfinished and needs to be evaluated.

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.
