| [ Upstream commit 44b615ac9fab16d1552cd8360454077d411e3c35 ] |
| |
| Tag the highest "Power Optimized" (1.5 GHz) Cortex-A57 operating point |
| table entries for the RZ/G2M, R-Car M3-W and M3-W+ SoCs with the |
| "opp-suspend" property. This makes sure the system will enter suspend |
| in the same performance state as it will be resumed by the firmware |
| later, avoiding state inconsistencies after resume. |
| |
| Based on a patch for R-Car M3-W in the BSP by Takeshi Kihara |
| <takeshi.kihara.df@renesas.com>. |
| |
| Fixes: 800037e815b91d8c ("arm64: dts: renesas: r8a774a1: Add operating points") |
| Fixes: da7e3113344fda50 ("arm64: dts: renesas: r8a7796: Add OPPs table for cpu devices") |
| Fixes: f51746ad7d1ff6b4 ("arm64: dts: renesas: Add Renesas R8A77961 SoC support") |
