Subject: [PATCH v5 24/24] ARM: DRA7: clockdomain: Change the CLKTRCTRL of CM_PCIE_CLKSTCTRL to SW_WKUP
Date: Mon, 27 Mar 2017 15:15:20 +0530 [thread overview]
Message-ID: <20170327094520.3129-25-kishon@ti.com> (raw)
In-Reply-To: <20170327094520.3129-1-kishon@ti.com>
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.
