[PATCH v3 0/5] K2G: Add QSPI support

[Vignesh R <vigneshr@ti.com>]

This series adds support for Cadence QSPI IP present in TI's 66AK2G SoC.
The patches enhance the existing cadence-quadspi driver to support
loopback clock circuit, pm_runtime support and tweaks for 66AK2G SoC.

Change log:

v3:
* Fix build warnings reported by kbuild test bot.

Resend:
* Rebase to latest linux-next.
* Collect Acked-bys

v2:
* Drop DT patches. Will be sent as separate series as requested by
 maintainer.
* Split binding docs into separate patches.
* Address comments by Rob Herring.
