Subject: [PATCH v2 2/2] PCI: qcom: Update ICC and OPP values during link up event
Date: Fri, 20 Sep 2024 15:48:00 +0530	[thread overview]
Message-ID: <20240920-remove_wait-v2-2-7c0fcb3b581d@quicinc.com> (raw)
In-Reply-To: <20240920-remove_wait-v2-0-7c0fcb3b581d@quicinc.com>

As part of the PCIe link up event, update ICC and OPP values
as at this point only driver can know the link speed and
width of the PCIe link.
