The order between "syscon" and "simple-mfd" is important because in these particular cases, the node needs to be first a "simple-mfd" to expose it's sub-nodes, and later on a "syscon" to permit other nodes to access this register space through the "syscon" mechanism.
Signed-off-by: Neil Armstrong <[email protected]> --- This also has a consequence for U-Boot since the U-Boot DM is much simpler and can only associate a single device to a node, thus here we want these nodes to be an mfd bus to be able to probe the sub-nodes. arch/arm64/boot/dts/amlogic/meson-axg.dtsi | 4 ++-- arch/arm64/boot/dts/amlogic/meson-gx.dtsi | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/arch/arm64/boot/dts/amlogic/meson-axg.dtsi b/arch/arm64/boot/dts/amlogic/meson-axg.dtsi index 6adc8d3..3f0de9d 100644 --- a/arch/arm64/boot/dts/amlogic/meson-axg.dtsi +++ b/arch/arm64/boot/dts/amlogic/meson-axg.dtsi @@ -342,7 +342,7 @@ ranges = <0x0 0x0 0x0 0xff63c000 0x0 0x1c00>; sysctrl: system-controller@0 { - compatible = "amlogic,meson-axg-hhi-sysctrl", "syscon", "simple-mfd"; + compatible = "amlogic,meson-axg-hhi-sysctrl", "simple-mfd", "syscon"; reg = <0 0 0 0x400>; clkc: clock-controller { @@ -1180,7 +1180,7 @@ ranges = <0x0 0x0 0x0 0xff800000 0x0 0x100000>; sysctrl_AO: sys-ctrl@0 { - compatible = "amlogic,meson-axg-ao-sysctrl", "syscon", "simple-mfd"; + compatible = "amlogic,meson-axg-ao-sysctrl", "simple-mfd", "syscon"; reg = <0x0 0x0 0x0 0x100>; clkc_AO: clock-controller { diff --git a/arch/arm64/boot/dts/amlogic/meson-gx.dtsi b/arch/arm64/boot/dts/amlogic/meson-gx.dtsi index b8dc4db..d88699f 100644 --- a/arch/arm64/boot/dts/amlogic/meson-gx.dtsi +++ b/arch/arm64/boot/dts/amlogic/meson-gx.dtsi @@ -344,7 +344,7 @@ ranges = <0x0 0x0 0x0 0xc8100000 0x0 0x100000>; sysctrl_AO: sys-ctrl@0 { - compatible = "amlogic,meson-gx-ao-sysctrl", "syscon", "simple-mfd"; + compatible = "amlogic,meson-gx-ao-sysctrl", "simple-mfd", "syscon"; reg = <0x0 0x0 0x0 0x100>; pwrc_vpu: power-controller-vpu { @@ -431,7 +431,7 @@ ranges = <0x0 0x0 0x0 0xc883c000 0x0 0x2000>; sysctrl: system-controller@0 { - compatible = "amlogic,meson-gx-hhi-sysctrl", "syscon", "simple-mfd"; + compatible = "amlogic,meson-gx-hhi-sysctrl", "simple-mfd", "syscon"; reg = <0 0 0 0x400>; }; -- 2.7.4
