From: Kishon Vijay Abraham I Date: Fri, 18 Aug 2017 14:58:02 +0000 (+0530) Subject: PCI: dwc: designware: Provide page_size to pci_epc_mem X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a937fe087aa1de5df35c31a261b0f5f6808a7052;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git PCI: dwc: designware: Provide page_size to pci_epc_mem Use the newly introduced __pci_epc_mem_init() instead of pci_epc_mem_init() to provide page_size to pci_epc_mem. This is in preparation for adding EP support to K2G which has a restriction that the address region should be either divided into 1MB/2MB/4MB or 8MB sizes (Ref: 11.14.4.9.1 Outbound Address Translation in K2G TRM SPRUHY8F January 2016 – Revised May 2017).
