Everyone:
This seires is a build-up on previously submitted PCI sync set [1] and
contains the patches I created while working on adding support for
PCIe on i.MX7. The series consists of following:
- Patches adding necessary regulator pluming to support porint ANATOP
driver
- ANATOP driver port
- Port of basic power domain infrastructure from Linux kernel needed
for controlling GPCv2 (useful for both i.MX7 and, especially, for
i.MX8MQ)
- Port of GPCv2 driver from Linux as well as of some bug fixes for it
- Port of i.MX7 reset controller driver
- Patches adding support for i.MX7 to existing i.MX6 PCIe host
controller driver
- Misc fixes
This series has been tested on i.MX7D SabreSD board against Toshiba
NVMe device.
Feedback is welcome!
Changes since [v2]:
- Dropped "base: Port driver_deferred_probe_check_state() from
Linux" and adjusted the rest of the series accordingly
Changes since [v1]:
- Patches containing bugfixes for GPCv2 were squashed into the patch
introducing the driver
- Patches containing bugfixes for i.MX7 reset controller were
squashed into the patch introducing the driver
- Deffered probe by GPIO support in i.MX6 PCI driver fixed by having
GPIO request preceed the call to dev_request_mem_resource()
Thanks,
Andrey Smirnov
