sysreset: Support reset via Renesas RAA215300 PMIC 2024-02-28T17:42:27+00:00 Paul Barker paul.barker.ct@bp.renesas.com 2024-02-27T20:40:33+00:00 167eb89a211a52c20d47b031a1053a74bbca1942 This patch adds support for resetting a board via the RAA215300 PMIC. Note that the RAA215300 documentation names the available reset types differently to u-boot: * A "warm" reset via the RAA215300 PMIC will fully reset the SoC (CPU & GPIOs), so this corresponds to SYSRESET_COLD. * A "cold" reset via the RAA215300 PMIC will cycle all power supply rails, so this corresponds to SYSRESET_POWER.
