[PATCH v3 00/30] phy: qcom,qmp: fix dt-bindings and deprecate lane suffix

[Johan Hovold <johan+linaro@kernel.org>]

When adding support for SC8280XP to the QMP PHY driver I noticed that
the PHY provider child node was not described by the current DT schema.

The SC8280XP PHYs also need a second fixed-divider PIPE clock
("pipediv2") and I didn't want to have to add a bogus "lane" suffix to
the clock name just to match the current "pipe0" name so I decided to
deprecate the unnecessary suffix in the current binding instead.

To be able to add the missing child-node schema and handle device
specifics like additional PIPE clocks, it quickly became obvious that
the binding needs to be split up.

This series clean up and fixes some issue with the current schema before
splitting it up in separate schemas for PCIe, UFS and USB and adding
missing parts like the child PHY provider nodes.

The MSM8996 PCIe PHY gets its own schema as this is the only non-combo
PHY that actually provides more than one PHY per IP block. Note that the
"lane" suffix is still unnecessary and misleading.

The final patches add support for the updated binding to the (recently
split up) PHY drivers. Included is also a related combo PHY cleanup.

Changes in v3
 - rebase on linux-next which has a new binding for IPQ8074
 - fix git-bisect breakage due to removal of an unused variable one
   patch too soon (Krzysztof)
 - replace one Fixes tag with reference in commit message (Krzysztof)
 - drop two redundant minItems (Krzysztof)
 - fix two Fixes tags that lacked the actual tag
 - add more ack and review tags from Krzysztof

Changes in v2
 - squash split + cleanup + example patches (Krzysztof)
 - deprecate clock-names instead of dropping suffix (Krzysztof)
 - deprecate reset-names instead of dropping suffix (Krzysztof)
 - flatten child reg if/then schemas (Krzysztof)
 - add back optional vddp-ref-clk to all bindings even though it likely
   only applies to MSM8996/98 UFS (Krzysztof)
 - add missing sc7180 schema to USB binding
 - misc clean ups
   - shorten or drop descriptions
   - drop quotes around $id and $schema (Krzysztof)
   - use maxItems with clock-output-names
   - combine two USB clock+reset schemas
 - add Reviewed-by/Acked-by tags
