Subject: [PATCH v2 1/3] PCI: qcom: Add sc7280 aggre0, aggre1 and ddr sf tbu clocks in PCIe driver
Date: Fri,  1 Jul 2022 21:41:37 +0530	[thread overview]
Message-ID: <1656691899-21315-2-git-send-email-quic_krichai@quicinc.com> (raw)
In-Reply-To: <1656691899-21315-1-git-send-email-quic_krichai@quicinc.com>

Add missing aggre0, aggre1 and ddrs sf tbu clocks in PCIe driver.

If these clocks are not voted-on, then PCIe link is going down when system
is suspended as these clocks can get turned off.

And these clocks are needed only on sc7280 target.
