Subject: [PATCH] clk: qcom: gcc-ipq6018: add QUP6 I2C clock
|
|
|
|
QUP6 I2C clock is listed in the dt bindings but it was never included in
|
|
the GCC driver.
|
|
So lets add support for it, it is marked as criticial as it is used by RPM
|
|
to communicate to the external PMIC over I2C so this clock must not be
|
|
disabled.
