Subject: [PATCH 0/4] arm64: dts: ti: j721e: Add HyperFlash support
Date: Fri, 5 May 2023 19:44:03 +0530	[thread overview]
Message-ID: <20230505141407.15134-1-vaishnav.a@ti.com> (raw)

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.

* 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:

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