This patch series is the second part of the former version 2 of the
patch series "Improve PCI memory mapping API". This second part is split
out as it deals solely with the rockchip/rk3399 PCI endpoint controller
driver.

This series is organized as follows:
- Patch 1 fixes the rockchip ATU programming
- Patch 2, 3 and 4 introduce small code improvments
- Patch 5 implements the .map_align() operation to make the rk3399
endpoint controller driver fully functional
- Patch 6, 7 and 8 refactor the driver code to make it more readable
- Patch 9 introduces the .stop() endpoint controller operation to
correctly disable the endpopint controller after use
- Patch 10 improves link training
- Patch 11 and 12 implement handling of the #PERST signal

Changes from v2:
- Split the patch series
- Corrected patch 11 to add the missing "maxItem"

Changes from v1:
- Changed pci_epc_check_func() to pci_epc_function_is_valid() in patch
1.
- Removed patch "PCI: endpoint: Improve pci_epc_mem_alloc_addr()"
(former patch 2 of v1)
- Various typos cleanups all over. Also fixed some blank space
indentation.
- Added review tags
