Subject: [PATCH v4 13/16] PCI: dwc: spacemit-k1: Use cached PCIe capability offset
Date: Tue, 27 Oct 2026 20:28:24 +0800 [thread overview]
Message-ID: <20261027122827.2725643-14-18255117159@163.com> (raw)
In-Reply-To: <20261027122827.2725643-1-18255117159@163.com>
k1_pcie_disable_aspm_l1() runs from the .init callback with the
controller already enabled. Replace the capability search with
dw_pcie_get_pcie_cap().
