Subject: [PATCH] clk: qcom: ipq8074: disable USB GDSC-s SW_COLLAPSE
|
|
|
|
Like in IPQ6018 Qualcomm intentionally disables the SW_COLLAPSE on the USB
|
|
GDSC-s.
|
|
|
|
This could potentially be better handled by utilizing the GDSC driver, but
|
|
I am not familiar with it nor do I have datasheets.
