From 7e9d2850a8db4e0d85a20bb692198bf2cc4be3b7 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Thu, 8 Sep 2016 11:11:00 +0200 Subject: ARM: dts: STiH410: Handle interconnect clock required by EHCI/OHCI (USB) The STiH4{07,10} platform contains some interconnect clocks which are used by various IPs. If this clock isn't handled correctly by ST's EHCI/OHCI drivers, their hub won't be found, the following error be shown and the result will be non-working USB: [ 97.221963] hub 2-1:1.0: hub_ext_port_status failed (err = -110) Cc: stable@vger.kernel.org Tested-by: Peter Griffin Signed-off-by: Lee Jones Acked-by: Patrice Chotard --- arch/arm/boot/dts/stih410.dtsi | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-) (limited to 'arch/arm') diff --git a/arch/arm/boot/dts/stih410.dtsi b/arch/arm/boot/dts/stih410.dtsi index 18ed1ad10d32..40318869c733 100644 --- a/arch/arm/boot/dts/stih410.dtsi +++ b/arch/arm/boot/dts/stih410.dtsi @@ -41,7 +41,8 @@ compatible = "st,st-ohci-300x"; reg = <0x9a03c00 0x100>; interrupts = ; - clocks = <&clk_s_c0_flexgen CLK_TX_ICN_DISP_0>; + clocks = <&clk_s_c0_flexgen CLK_TX_ICN_DISP_0>, + <&clk_s_c0_flexgen CLK_RX_ICN_DISP_0>; resets = <&powerdown STIH407_USB2_PORT0_POWERDOWN>, <&softreset STIH407_USB2_PORT0_SOFTRESET>; reset-names = "power", "softreset"; @@ -57,7 +58,8 @@ interrupts = ; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_usb0>; - clocks = <&clk_s_c0_flexgen CLK_TX_ICN_DISP_0>; + clocks = <&clk_s_c0_flexgen CLK_TX_ICN_DISP_0>, + <&clk_s_c0_flexgen CLK_RX_ICN_DISP_0>; resets = <&powerdown STIH407_USB2_PORT0_POWERDOWN>, <&softreset STIH407_USB2_PORT0_SOFTRESET>; reset-names = "power", "softreset"; @@ -71,7 +73,8 @@ compatible = "st,st-ohci-300x"; reg = <0x9a83c00 0x100>; interrupts = ; - clocks = <&clk_s_c0_flexgen CLK_TX_ICN_DISP_0>; + clocks = <&clk_s_c0_flexgen CLK_TX_ICN_DISP_0>, + <&clk_s_c0_flexgen CLK_RX_ICN_DISP_0>; resets = <&powerdown STIH407_USB2_PORT1_POWERDOWN>, <&softreset STIH407_USB2_PORT1_SOFTRESET>; reset-names = "power", "softreset"; @@ -87,7 +90,8 @@ interrupts = ; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_usb1>; - clocks = <&clk_s_c0_flexgen CLK_TX_ICN_DISP_0>; + clocks = <&clk_s_c0_flexgen CLK_TX_ICN_DISP_0>, + <&clk_s_c0_flexgen CLK_RX_ICN_DISP_0>; resets = <&powerdown STIH407_USB2_PORT1_POWERDOWN>, <&softreset STIH407_USB2_PORT1_SOFTRESET>; reset-names = "power", "softreset"; -- cgit v1.2.3
