[PATCH v2 0/4] arm64: dts: ti: j721e: Add HyperFlash support

From: Vaishnav Achath
Date: Sat May 13 2023 - 08:34:00 EST


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@xxxxxx/
* Add partitions information in Hyperflash node.

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

* 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@xxxxxx/

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