phy-sun4i-usb now has proper dr_mode handling, it always registers an extcon, and sends a notify with the mode (even when in peripheral- / host-only mode) at least once. So we can simply the sunxi musb glue by always registering its extcon notifier and relying on sunxi_musb_work() to enable vbus when in host-only mode. This also enables host- and peripheral-only mode with vbus monitoring.

This adds tracepoints to musb register read/write wrappers to get trace log for register access. The default tacepoint log prefix here would be musb_readX/writeX(), which is not much helpful.

This patch fixes an issue that the extcon_set_cable_state_() is possible to cause "BUG: scheduling while atomic" because this driver calls extcon_set_cable_state_() in the interrupt handler and mutex_lock() is possible to be called by like the following call trace.

The usb-phy is fully enclosed in the general register files (GRF). Therefore as seen from the device-tree it shouldn't be a separate platform-device but instead a sub-device of the GRF - using the simply-mfd mechanism.

overlay needs underlying fs to support d_type. Recently I put in a patch in to detect this condition and started failing mount if underlying fs did not support d_type. But this breaks existing configurations over kernel upgrade. Those who are running docker (partially broken configuration) with xfs not supporting d_type, are surprised that after kernel upgrade docker does not run anymore. https://github.com/docker/docker/issues/22937#issuecomment-229881315 So instead of erroring out, detect broken configuration and warn about it. This should allow existing docker setups to continue working after kernel upgrade.

However pte_modify for the 36 bit address space support is no affected. In that case additional bits in the final CCA mode may generate an invalid value for the CCA field. On the R10000 system where this was tracked down for example a CCA 7 has been observed, which is Uncached Accelerated. Fixed by: 1) Using the proper CCA mode for PAGE_NONE just like for all the other PAGE_* pte/pmd bits. 2) Fix the two affected variants of pte_modify. Further code inspection also shows the same issue to exist in pmd_modify which would affect huge page systems. Issue in pte_modify tracked down by Alastair Bridgewater, PAGE_NONE and pmd_modify issue found by me. The history of this goes back beyond Linus' git history. Chris Dearman's commit 35133692 ("[MIPS] Allow setting of the cache attribute at run time.") missed the opportunity to fix this but it was originally introduced in lmo commit d523832cf12007b3242e50bb77d0c9e63e0b6518 ("Missing from last commit.") and 32cc38229ac7538f2346918a09e75413e8861f87 ("New configuration option CONFIG_MIPS_UNCACHED.")
