[PATCH v2 0/2] arm64: dts: renesas: r8a7799[05]: Add cpg reset for DU

[Simon Horman]

Hi,

this short series adds CPG reset for DU of the
R-Car E3 (r8a77995) and D3 (r8a77990) SoCs.

Based on renesas-devel-20190624-v5.2-rc6

Changes since v2
- rewrote changelogs

Changes since v1
- only add one reset entry per group

[PATCH v3 1/2] arm64: dts: renesas: r8a77990: Add cpg reset for DU

[Simon Horman]

From: Takeshi Kihara <takeshi.kihara.df@renesas.com>

Add CPG reset properties to DU node of E3 (r8a77990) SoC.

According to Laurent Pinchart, R-Car Gen3 reset is handled at the group
level so specifying one reset entry per group is sufficient.

[PATCH v3 2/2] arm64: dts: renesas: r8a77995: Add cpg reset for DU

[Simon Horman]

From: Yoshihiro Kaneko <ykaneko0929@gmail.com>

Add CPG reset properties to DU node of D3 (r8a77995) SoC.

According to Laurent Pinchart, R-Car Gen3 reset is handled at the group
level so specifying one reset entry per group is sufficient.

This patch was inspired by a patch in the BSP by
Takeshi Kihara <takeshi.kihara.df@renesas.com>.
