From mboxrd@z Thu Jan 1 00:00:00 1970 From: kishon@ti.com (Kishon Vijay Abraham I) Date: Mon, 27 Mar 2017 15:15:20 +0530 Subject: [PATCH v5 24/24] ARM: DRA7: clockdomain: Change the CLKTRCTRL of CM_PCIE_CLKSTCTRL to SW_WKUP In-Reply-To: <20170327094520.3129-1-kishon@ti.com> References: <20170327094520.3129-1-kishon@ti.com> Message-ID: <20170327094520.3129-25-kishon@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The PCIe programming sequence in TRM suggests CLKSTCTRL of PCIe should be set to SW_WKUP. There are no issues when CLKSTCTRL is set to HW_AUTO in RC mode. However in EP mode, the host system is not able to access the MEMSPACE and setting the CLKSTCTRL to SW_WKUP fixes it.
