PCI: qcom: Fix the fixup of PCI_VENDOR_ID_QCOM

2020-04-17T14:12:02Z

commit 604f3956524a6a53c1e3dd27b4b685b664d181ec upstream. There exists non-bridge PCIe devices with PCI_VENDOR_ID_QCOM, so limit the fixup to only affect the relevant PCIe bridges.

PCI: keystone: Fix error handling when "num-viewport" DT property is not populated

2020-02-11T12:36:50Z

commit b0de922af53eede340986a2d05b6cd4b6d6efa43 upstream. Fix error handling when "num-viewport" DT property is not populated. Fixes: 23284ad677a9 ("PCI: keystone: Add support for PCIe EP in AM654x Platforms") Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Lorenzo Pieralisi Cc: stable@vger.kernel.org # v5.2+ Signed-off-by: Greg Kroah-Hartman

PCI: keystone: Fix link training retries initiation

2020-02-11T12:36:49Z

commit 6df19872d881641e6394f93ef2938cffcbdae5bb upstream. ks_pcie_stop_link() function does not clear LTSSM_EN_VAL bit so link training was not triggered more than once after startup. In configurations where link can be unstable during early boot, for example, under low temperature, it will never be established.

PCI: keystone: Fix outbound region mapping

2020-02-11T12:36:49Z

commit 2d0c3fbe43fa0e6fcb7a6c755c5f4cd702c0d2f4 upstream. The Keystone outbound Address Translation Unit (ATU) maps PCI MMIO space in 8 MB windows. When programming the ATU windows, we previously incremented the starting address by 8, not 8 MB, so all the windows were mapped to the first 8 MB. Therefore, only 8 MB of MMIO space was accessible. Update the loop so it increments the starting address by 8 MB, not 8, so more MMIO space is accessible. Fixes: e75043ad9792 ("PCI: keystone: Cleanup outbound window configuration") Link: https://lore.kernel.org/r/20191004154811.GA31397@monakov-y.office.kontur-niirs.ru Signed-off-by: Yurii Monakov [bhelgaas: commit log] Signed-off-by: Bjorn Helgaas Signed-off-by: Lorenzo Pieralisi Acked-by: Andrew Murray Acked-by: Kishon Vijay Abraham I Cc: stable@vger.kernel.org # v4.20+ Signed-off-by: Greg Kroah-Hartman
