[PATCH 6.1 584/798] clk: qcom: gcc-sm8450: Do not turn off PCIe GDSCs during gdsc_disable()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxx>

commit 889e1332310656961855c0dcedbb4dbe78e39d22 upstream.

With PWRSTS_OFF_ON, PCIe GDSCs are turned off during gdsc_disable(). This
can happen during scenarios such as system suspend and breaks the resume
of PCIe controllers from suspend.

So use PWRSTS_RET_ON to indicate the GDSC driver to not turn off the GDSCs
during gdsc_disable() and allow the hardware to transition the GDSCs to
retention when the parent domain enters low power state during system
suspend.
