This needs 1.35V. The -1.35V for DDR3L rail at run-time is selected by the proper configuration -on SELV2 pin (for 1.35V it needs to be in high-z state). When suspended -the MCP16502 PMIC soldered on SAMA7G5-EK will use different sets of -configuration registers to provide proper voltages on its rail. Run-time -configuration registers could be configured differently than suspend -configuration register for MCP16502 (VSEL2 affects only run-time -configuration). In suspend states the DDR3L memory soldered on SAMA7G5-EK -switches to self-refresh. Even on self-refresh it needs to be powered by -a 1.35V rail. Thus, make sure the PMIC is configured properly when system -is suspended. - -Fixes: 7540629e2fc7 (ARM: dts: at91: add sama7g5 SoC DT and sama7g5-ek") -Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com> -Signed-off-by: Nicolas Ferre <nicolas.ferre@microchip.com> -Link: https://lore.kernel.org/r/20210930154219.2214051-2-claudiu.beznea@microchip.com ---- - arch/arm/boot/dts/at91-sama7g5ek.dts | 2 ++ - 1 file changed, 2 insertions(+) - ---- a/arch/arm/boot/dts/at91-sama7g5ek.dts -+++ b/arch/arm/boot/dts/at91-sama7g5ek.dts -@@ -196,11 +196,13 @@ - - regulator-state-standby { - regulator-on-in-suspend; -+ regulator-suspend-microvolt = <1350000>; - regulator-mode = <4>; - }; - - regulator-state-mem { - regulator-on-in-suspend; -+ regulator-suspend-microvolt = <1350000>; - regulator-mode = <4>; - }; - }; |
