This series addresses a PCIe reliability issue as observed on Apalis T30
related to a PCIe reset timing violation.
This series is available at http://git.toradex.com/cgit/u-boot-toradex.git/log/?h=for-next
Changes in v3:
- Updated copyright period to 2014-2018.
- Added a blank line after declarations as warned by patman.
- Added Stephen's acked-by.
- Rebased and resend as series so far never got applied!
Changes in v2:
- Leave resp. enable all port 0 pins input drivers as a customer may
optionally want to use some of those MXM3 pins as inputs as well.
- Stick to struct tegra_pcie_port as suggested by Stephen.
- Introduce proper CONFIG_APALIS_T30_PCIE_EVALBOARD_INIT Kconfig option
as suggested by Stephen.
- Improved the ifdef vs. if curly braces sequencing as suggested by
Stephen.
- Keep PCIe port reset status in order to safeguard for future changes
to the port reset order or even allow for re-initialisation should
that ever be implemented in the higher levels of the driver model.
