NOTE: To test this patchset with real i.MX7 hardware, additional patches, that are being upstreamed via different trees, are needed. Full working tree is availible at: https://github.com/ndreys/linux/tree/imx7d/pcie-support-v8 Changes since v7 (can be found at [version7]): - Collected Reviewed-by for the whole series from Lucas Changes since v6 (can be found at [version6]): - Rebased against latest changes in 'next' of PCI subsystem git tree Chagnes since v5 (can be found at [version5]): - Collected ACKs from Lee and Rob Changes since v4 (can be found at [version4]): - Dropped typo-fix patch (originally patch #1 of the series). - Added patch with workaround to address speed change false failures (I kept it as a separate patch to better document exchange with NXP/Freescale that lead to that patch) - Added patch to avoid speed change on links configured Gen1 only (Let me know if that is a terrible idea) - Addressed section mismatch problem by moving call to hook_fault_code to happend before driver registration. Changes since v3 (can be found at [version3]): - Move all of the reset_control_assert's into imx6_pcie_assert_core_reset - Documented required reset and power domain DT bindings Changes since v2 (can be found at [version2]): - Collected Reviewed-by for patch #2 from Lucas - Reset logic implementation moved out into a reset controller driver (see [reset1]) - Removed unused leftover code Changes since v1 (can be found at [version1]): - All GPC related code moved into a separate driver (see [gpc1]) - Removed GPIO probe deferral logging - Fixed section mismatch warning - Minor reformatting of fsl,imx6q-pcie.txt(as per Rob Herring's request) [version7] https://lkml.org/lkml/2017/3/21/331 [version6] https://lkml.org/lkml/2017/3/14/584 [version5] https://lkml.org/lkml/2017/2/20/376 [version4] https://lkml.org/lkml/2017/2/7/478 [version3] https://lkml.org/lkml/2017/2/6/565 [version2] https://lkml.org/lkml/2017/2/1/510 [version1] https://lkml.org/lkml/2017/1/19/488 [gpc1] https://lkml.org/lkml/2017/2/6/551 [reset1] https://lkml.org/lkml/2017/2/6/554 Andrey Smirnov (4): PCI: imx6: Add code to support i.MX7D PCI: imx6: Allow probe deferal by reset GPIO PCI: imx6: Do not wait for speed change on i.MX7 PCI: imx6: Do not switch speed if Gen2 is disabled .../devicetree/bindings/pci/fsl,imx6q-pcie.txt | 13 +- drivers/pci/dwc/pci-imx6.c | 198 +++++++++++++++------ include/linux/mfd/syscon/imx7-iomuxc-gpr.h | 4 + 3 files changed, 160 insertions(+), 55 deletions(-) -- 2.9.3
