Signed-off-by: Joakim Zhang <qiangqing.zhang@xxxxxxx> Signed-off-by: Marcel Ziswiler <marcel.ziswiler@xxxxxxxxxxx> Tested-by: Alexander Stein <alexander.stein@xxxxxxxxxxxxxxx> # TQMa8XQP --- (no changes since v6) Changes in v6: - Add Alexander's tested-by. Thanks! Changes in v4: - New patch combining the following downstream patches: commit e8fe3f57223a ("arm64: dts: imx8qxp: add FlexCAN in adma") commit 4e90361f1ed3 ("arm64: dts: imx8qxp: add multi-pd support for CAN1/2") commit 899f516e61f8 ("arm64: dts: imx8: dma: fully switched to new clk binding") commit 8a28ca15a058 ("arm64: dts: imx8qxp: drop multi-pd for CAN device") commit c493402197dd ("arm64: dts: imx8: update CAN fsl,clk-source and fsl,scu-index property") .../arm64/boot/dts/freescale/imx8-ss-dma.dtsi | 72 +++++++++++++++++++ 1 file changed, 72 insertions(+) diff --git a/arch/arm64/boot/dts/freescale/imx8-ss-dma.dtsi b/arch/arm64/boot/dts/freescale/imx8-ss-dma.dtsi index 6ccf926b77a5..2dce8f2ee3ea 100644 --- a/arch/arm64/boot/dts/freescale/imx8-ss-dma.dtsi +++ b/arch/arm64/boot/dts/freescale/imx8-ss-dma.dtsi @@ -298,6 +298,65 @@ adc1: adc@5a890000 { status = "disabled"; }; + flexcan1: can@5a8d0000 { + compatible = "fsl,imx8qm-flexcan"; + reg = <0x5a8d0000 0x10000>; + interrupts = <GIC_SPI 235 IRQ_TYPE_LEVEL_HIGH>; + interrupt-parent = <&gic>; + clocks = <&can0_lpcg 1>, + <&can0_lpcg 0>; + clock-names = "ipg", "per"; + assigned-clocks = <&clk IMX_SC_R_CAN_0 IMX_SC_PM_CLK_PER>; + assigned-clock-rates = <40000000>; + power-domains = <&pd IMX_SC_R_CAN_0>; + /* SLSlice[4] */ + fsl,clk-source = /bits/ 8 <0>; + fsl,scu-index = /bits/ 8 <0>; + status = "disabled"; + }; + + flexcan2: can@5a8e0000 { + compatible = "fsl,imx8qm-flexcan"; + reg = <0x5a8e0000 0x10000>; + interrupts = <GIC_SPI 236 IRQ_TYPE_LEVEL_HIGH>; + interrupt-parent = <&gic>; + /* CAN0 clock and PD is shared among all CAN instances as + * CAN1 shares CAN0's clock and to enable CAN0's clock it + * has to be powered on. + */ + clocks = <&can0_lpcg 1>, + <&can0_lpcg 0>; + clock-names = "ipg", "per"; + assigned-clocks = <&clk IMX_SC_R_CAN_0 IMX_SC_PM_CLK_PER>; + assigned-clock-rates = <40000000>; + power-domains = <&pd IMX_SC_R_CAN_1>; + /* SLSlice[4] */ + fsl,clk-source = /bits/ 8 <0>; + fsl,scu-index = /bits/ 8 <1>; + status = "disabled"; + }; + + flexcan3: can@5a8f0000 { + compatible = "fsl,imx8qm-flexcan"; + reg = <0x5a8f0000 0x10000>; + interrupts = <GIC_SPI 237 IRQ_TYPE_LEVEL_HIGH>; + interrupt-parent = <&gic>; + /* CAN0 clock and PD is shared among all CAN instances as + * CAN2 shares CAN0's clock and to enable CAN0's clock it + * has to be powered on. + */ + clocks = <&can0_lpcg 1>, + <&can0_lpcg 0>; + clock-names = "ipg", "per"; + assigned-clocks = <&clk IMX_SC_R_CAN_0 IMX_SC_PM_CLK_PER>; + assigned-clock-rates = <40000000>; + power-domains = <&pd IMX_SC_R_CAN_2>; + /* SLSlice[4] */ + fsl,clk-source = /bits/ 8 <0>; + fsl,scu-index = /bits/ 8 <2>; + status = "disabled"; + }; + i2c0_lpcg: clock-controller@5ac00000 { compatible = "fsl,imx8qxp-lpcg"; reg = <0x5ac00000 0x10000>; @@ -369,4 +428,17 @@ adc1_lpcg: clock-controller@5ac90000 { "adc1_lpcg_ipg_clk"; power-domains = <&pd IMX_SC_R_ADC_1>; }; + + can0_lpcg: clock-controller@5acd0000 { + compatible = "fsl,imx8qxp-lpcg"; + reg = <0x5acd0000 0x10000>; + #clock-cells = <1>; + clocks = <&clk IMX_SC_R_CAN_0 IMX_SC_PM_CLK_PER>, + <&dma_ipg_clk>, <&dma_ipg_clk>; + clock-indices = <IMX_LPCG_CLK_0>, <IMX_LPCG_CLK_4>, <IMX_LPCG_CLK_5>; + clock-output-names = "can0_lpcg_pe_clk", + "can0_lpcg_ipg_clk", + "can0_lpcg_chi_clk"; + power-domains = <&pd IMX_SC_R_CAN_0>; + }; }; -- 2.36.1
