Subject: [PATCH AUTOSEL 4.18 105/136] arm64: dts: renesas: Fix VSPD registers
 range

From: Laurent Pinchart <laurent.pinchart+renesas@...asonboard.com>

[ Upstream commit e21adc781bb45e810f1c396c4bc2c1624a4c25b9 ]

The VSPD and FCPVD nodes have overlapping register ranges, as the FCPVD
devices are mapped in the memory range usually used by the VSP LUT and
CLU, which are not present in the VSPD. Fix this by shortening the VSPD
registers range to 0x5000.

Fixes: 9f8573e38a0b ("arm64: dts: renesas: r8a7795: Add VSP instances")
Fixes: 291e0c4994d0 ("arm64: dts: r8a7795: Add support for R-Car H3 ES2.0")
Fixes: f06ffdfbdd90 ("arm64: dts: r8a7796: Add VSP instances")
Fixes: b4f92030d5d3 ("arm64: dts: renesas: r8a77970: add VSPD support")
Fixes: 295952a183d3 ("arm64: dts: renesas: r8a77995: add VSP instances")
Fixes: 85cb3229218a ("arm64: dts: renesas: r8a77965: Add VSP instances")
