Subject: [PATCH] clk: qcom: Add EBI2 clocks for IPQ806x
|
|
|
|
The NAND controller within EBI2 requires EBI2_CLK and
|
|
EBI2_ALWAYS_ON_CLK clocks. Create structs for these clocks so
|
|
that they can be used by the NAND controller driver. Add an entry
|
|
for EBI2_AON_CLK in the gcc-ipq806x DT binding document.
