From e3af9f7c6ece29fdb7fe0aeb83ac5d3077a06edb Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Tue, 25 Jul 2017 16:51:20 +0200 Subject: [PATCH] ARM64: dts: marvell: armada-cp110: Fix clock resources for various node On the CP modules we found on Armada 7K/8K, many IP block actually also need a "functional" clock (from the bus). This patch add them which allows to fix some issues hanging the kernel: If Ethernet and sdhci driver are built as modules and sdhci was loaded first then the kernel hang. Fixes: bb16ea1742c8 ("mmc: sdhci-xenon: Fix clock resource by adding an optional bus clock") Cc: stable@vger.kernel.org Reported-by: Riku Voipio Signed-off-by: Gregory CLEMENT --- .../arm64/boot/dts/marvell/armada-cp110-master.dtsi | 13 ++++++++----- arch/arm64/boot/dts/marvell/armada-cp110-slave.dtsi | 9 ++++++--- 2 files changed, 14 insertions(+), 8 deletions(-) diff --git a/arch/arm64/boot/dts/marvell/armada-cp110-master.dtsi b/arch/arm64/boot/dts/marvell/armada-cp110-master.dtsi index e3b64d03fbd8..9c7724e82aff 100644 --- a/arch/arm64/boot/dts/marvell/armada-cp110-master.dtsi +++ b/arch/arm64/boot/dts/marvell/armada-cp110-master.dtsi @@ -63,8 +63,10 @@ cpm_ethernet: ethernet@0 { compatible = "marvell,armada-7k-pp22"; reg = <0x0 0x100000>, <0x129000 0xb000>; - clocks = <&cpm_clk 1 3>, <&cpm_clk 1 9>, <&cpm_clk 1 5>; - clock-names = "pp_clk", "gop_clk", "mg_clk"; + clocks = <&cpm_clk 1 3>, <&cpm_clk 1 9>, + <&cpm_clk 1 5>, <&cpm_clk 1 18>; + clock-names = "pp_clk", "gop_clk", + "mg_clk","axi_clk"; marvell,system-controller = <&cpm_syscon0>; status = "disabled"; dma-coherent; @@ -155,7 +157,8 @@ #size-cells = <0>; compatible = "marvell,orion-mdio"; reg = <0x12a200 0x10>; - clocks = <&cpm_clk 1 9>, <&cpm_clk 1 5>; + clocks = <&cpm_clk 1 9>, <&cpm_clk 1 5>, + <&cpm_clk 1 6>, <&cpm_clk 1 18>; status = "disabled"; }; @@ -338,8 +341,8 @@ compatible = "marvell,armada-cp110-sdhci"; reg = <0x780000 0x300>; interrupts = ; - clock-names = "core"; - clocks = <&cpm_clk 1 4>; + clock-names = "core","axi"; + clocks = <&cpm_clk 1 4>, <&cpm_clk 1 18>; dma-coherent; status = "disabled"; }; diff --git a/arch/arm64/boot/dts/marvell/armada-cp110-slave.dtsi b/arch/arm64/boot/dts/marvell/armada-cp110-slave.dtsi index 0d51096c69f8..87ac68b2cf37 100644 --- a/arch/arm64/boot/dts/marvell/armada-cp110-slave.dtsi +++ b/arch/arm64/boot/dts/marvell/armada-cp110-slave.dtsi @@ -63,8 +63,10 @@ cps_ethernet: ethernet@0 { compatible = "marvell,armada-7k-pp22"; reg = <0x0 0x100000>, <0x129000 0xb000>; - clocks = <&cps_clk 1 3>, <&cps_clk 1 9>, <&cps_clk 1 5>; - clock-names = "pp_clk", "gop_clk", "mg_clk"; + clocks = <&cps_clk 1 3>, <&cps_clk 1 9>, + <&cps_clk 1 5>, <&cps_clk 1 18>; + clock-names = "pp_clk", "gop_clk", + "mg_clk", "axi_clk"; marvell,system-controller = <&cps_syscon0>; status = "disabled"; dma-coherent; @@ -155,7 +157,8 @@ #size-cells = <0>; compatible = "marvell,orion-mdio"; reg = <0x12a200 0x10>; - clocks = <&cps_clk 1 9>, <&cps_clk 1 5>; + clocks = <&cps_clk 1 9>, <&cps_clk 1 5>, + <&cps_clk 1 6>, <&cps_clk 1 18>; status = "disabled"; };
