[v3] renesas: r8a779g0: Enable VSPX on R-Car V4H

[PATCH v3 0/4] renesas: r8a779g0: Enable VSPX on R-Car V4H

Posted by Jacopo Mondi 12 months ago

The series enables the two VSPX instances connected to the R-Car ISP
on Renesas R-Car V4H. Define clock identifiers based on the MSTPCR id
for the VSPX instances and defined device nodes in the V4H .dts file.

The VSPX modules interface with extenal memory through dedicated FCP
instances named FCPVX. Before defining VSPDX, define and enable the
FXPVX instances as well.

Compile-tested only series.

Changes in v3:
- Test on an actual board and fix the VSPX and FCPVX power domains to
  use the ISP power domains
- Re-parent the VSPX and FCPVX clocks to the 800MHz S0D1
- Link to v2: https://lore.kernel.org/r/20241218-rcar-v4h-vspx-v2-0-c673647d96e1@ideasonboard.com

Changes in v2:
- Collect tags
- Re-sort nodes by unit address
- Link to v1: https://lore.kernel.org/r/20241217-rcar-v4h-vspx-v1-0-de04ea044ed4@ideasonboard.com

Ah yes, leftover from v1 and v2 where I hadn't access to the board
(yet)
