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: https://lore.kernel.org/all/20230419040007.3022780-2-u-kumar1@ti.com/
