This series patches refine pci-imx6 driver and do the following changes.
- Encapsulate the clock enable into one standalone function
- Add the error propagation from host_init
- Balance the usage of the regulator and clocks when link never came up
- Add the compliance tests mode support
Main changes from v4 to v5:
- Since i.MX8MM PCIe support had been merged. Based on Lorenzo's git repos,
rebase and resend the patch-set.
Main changes from v3 to v4:
- Regarding Mark's comments, delete the regulator_is_enabled() check.
- Squash #3 and #6 of v3 patch into #5 patch of v4 set.
Main changes from v2 to v3:
- Add "Reviewed-by: Lucas Stach <l.stach@xxxxxxxxxxxxxx>" tag into
first two patches.
- Add a Fixes tag into #3 patch.
- Split the #4 of v2 to two patches, one is clock disable codes move,
the other one is the acutal clock unbalance fix.
- Add a new host_exit() callback into dw_pcie_host_ops, then it could be
invoked to handle the unbalance issue in the error handling after
host_init() function when link is down.
- Add a new host_exit() callback for i.MX PCIe driver to handle this case
in the error handling after host_init.
Main changes from v1 to v2:
Regarding Lucas' comments.
- Move the placement of the new imx6_pcie_clk_enable() to avoid the
forward declarition.
- Seperate the second patch of v1 patch-set to three patches.
- Use the module_param to replace the kernel command line.
Regarding Bjorn's comments:
- Use the cover-letter for a multi-patch series.
- Correct the subject line, and refine the commit logs. For example,
remove the timestamp of the logs.
