Everyone:
This is the series containing various small improvements that I made while reading the code and researching commit history of pci-imx6.c and pcie-designware*.c files. All changes are optional, so commits that don't seem like an improvement can be easily dropped. Hopefully each patch is self-explanatory.
I tested this series on i.MX6Q, i.MX7D and i.MX8MQ.
Feedback is welcome!
Thanks, Andrey Smirnov
Chagnes since [v3]:
- Collected Reviewed-by from Lucas for most of the patches
- Converted "PCI: imx6: Replace calls to udelay() with usleep_range()" to "PCI: imx6: Use usleep_range() in imx6_pcie_enable_ref_clk()"
- Converted "PCI: imx6: Remove redundant debug tracing" to "PCI: imx6: Drop imx6_pcie_wait_for_link()"
- Converted all of the callers of pcie_phy_poll_ack() to use true/false in "PCI: imx6: Simplify pcie_phy_poll_ack()"
Changes since [v2]:
- All non i.MX6 patches dropped, since they were accepted as a seprarte series
- Series rebased on latest 'dwc-pci' branch of PCI tree
- Patches "PCI: imx6: Use flags to indicate support for suspend" and "PCI: imx6: Replace calls to udelay() with usleep_range()" added to the series
Changes since [v1]:
- Dropped "PCI: imx6: Drop imx6_pcie_link_up()" due to the matter already having been addressed by "PCI: imx6: Fix link training status detection in link up check" from Trent Piepho
- Changed "designware" -> "dwc" for all subject lines
- Collected Acked-by's from Gustavo Pimentel
