  This series adds hyperflash support for J721E. J721E SoC has HyperBus
and OSPI controller muxed within the FSS subsystem and the J721E SoM
has a 64 MiB S28 OSPI flash and a 64 MiB Hyperflash present which is
muxed externally also.

Changelog:
V1->V2:
 * Address feedback in similar series:
 https://lore.kernel.org/all/feddcd03-1848-b667-6a38-ae7c0f6ff160@ti.com/
 * Add partitions information in Hyperflash node.

V1: https://lore.kernel.org/all/20230505141407.15134-1-vaishnav.a@ti.com/

* Patch 1/4 adds the hyperbus controller nodes and fixes DT compile
warnings.
* Patch 2/4 adds the hyperflash support in the SoM DTS.
* Patch 3 and 4/4 enables the pinmux for external mux that selects
between hyperflash or OSPI NOR flash, this is done for J7200 and 
J721E platforms since it is required in U-Boot and helps keep the
DT in sync.

Patch 1/4 depends on the following patch:
https://lore.kernel.org/all/20230424184810.29453-1-afd@ti.com/

Patch 3 depends on the below fix for pinmux offsets in J7200:

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
