Hello, everyone:
This is a sixth iteration of the code that adds PCI-subsystem bits
necessary for enabling PCI support on i.MX7.
Chagnes since v5:
- Collected ACKs from Lee and Rob
Changes since v4 (can be found at [version4]):
- Dropped typo-fix patch (originally patch #1 of the
series). Bjorn, I am assuming that patch from v4 survived
and stayed in your tree, let me know if that is not true.
- 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)

PCI: imx6: Add code to support i.MX7D
PCI: imx6: Do not wait for speed change on i.MX7
PCI: imx6: Do not switch speed if Gen2 is disabled
PCI: imx6: Allow probe deferal by reset GPIO
