This currently works with the\nlegacy platform data still around.\n\nTo fix this, let's add the interconnect target modules so we can\nidle the unused interconnect target module on init.\n\nAlso note that adding the interconnect target module node does not\nnecessarily mean that there is a driver available for the child IP\nblock, or that the child IP block is even functional.\n\nIn the SGX case, the PowerVR driver is closed source. And McASP on\nomap4 has at least the TX path disabled and is not supported by the\ndavinci-mcasp driver. For AESS there is old Android 3.4 kernel\ndriver available but it's unlikely that anybody is going to update\nit for the mainline kernel.\n\nFor smarflex, we are still probing with platform data and the\ndriver needs more work before we can add the device ip child nodes.\n\nAnd finally, we're not yet using the interconnet ranges. I will\nbe posting separate patches for those later on.\n\nCc: Benoît Cousson \nCc: Laurent Pinchart \nCc: Liam Girdwood \nCc: Mark Brown \nCc: Mark Rutland \nCc: Mauro Carvalho Chehab \nCc: Nishanth Menon \nCc: Matthijs van Duin \nCc: Paul Walmsley \nCc: Peter Ujfalusi \nCc: Rob Herring \nCc: Sakari Ailus \nCc: Tero Kristo \nCc: Tomi Valkeinen \nSigned-off-by: Tony Lindgren \n---\n arch/arm/boot/dts/omap4.dtsi | 179 ++++++++++++++++++++++++++++++++++++++++---\n 1 file changed, 167 insertions(+), 12 deletions(-)","diff":"diff --git a/arch/arm/boot/dts/omap4.dtsi b/arch/arm/boot/dts/omap4.dtsi\n--- a/arch/arm/boot/dts/omap4.dtsi\n+++ b/arch/arm/boot/dts/omap4.dtsi\n@@ -392,6 +392,21 @@\n \t\t\t#interrupt-cells = <2>;\n \t\t};\n \n+\t\ttarget-module@48076000 {\n+\t\t\tcompatible = \"ti,sysc-type2\";\n+\t\t\tti,hwmods = \"slimbus2\";\n+\t\t\treg = <0x48076000 0x4>,\n+\t\t\t <0x48076010 0x4>;\n+\t\t\treg-names = \"rev\", \"sysc\";\n+\t\t\tclocks = <&l4_per_clkctrl OMAP4_SLIMBUS2_CLKCTRL 0>;\n+\t\t\tclock-names = \"clkctrl\";\n+\t\t\t#address-cells = <1>;\n+\t\t\t#size-cells = <1>;\n+\t\t\tranges = <0 0x48076000 0x001000>;\n+\n+\t\t\t/* No child device binding or driver in mainline */\n+\t\t};\n+\n \t\telm: elm@48078000 {\n \t\t\tcompatible = \"ti,am3352-elm\";\n \t\t\treg = <0x48078000 0x2000>;\n@@ -452,25 +467,61 @@\n \t\t\tclock-frequency = <48000000>;\n \t\t};\n \n-\t\tsmartreflex_iva: smartreflex@4a0db000 {\n-\t\t\tcompatible = \"ti,omap4-smartreflex-iva\";\n-\t\t\treg = <0x4a0db000 0x80>;\n-\t\t\tinterrupts = ;\n+\t\ttarget-module@4a0db000 {\n+\t\t\tcompatible = \"ti,sysc-sr\";\n \t\t\tti,hwmods = \"smartreflex_iva\";\n+\t\t\treg = <0x4a0db000 0x4>,\n+\t\t\t <0x4a0db008 0x4>;\n+\t\t\treg-names = \"rev\", \"sysc\";\n+\t\t\tclocks = <&l4_ao_clkctrl OMAP4_SMARTREFLEX_IVA_CLKCTRL 0>;\n+\t\t\tclock-names = \"clkctrl\";\n+\t\t\t#address-cells = <1>;\n+\t\t\t#size-cells = <1>;\n+\t\t\tranges = <0 0x4a0db000 0x001000>;\n+\n+\t\t\tsmartreflex_iva: smartreflex@0 {\n+\t\t\t\tcompatible = \"ti,omap4-smartreflex-iva\";\n+\t\t\t\treg = <0 0x80>;\n+\t\t\t\tinterrupts = ;\n+\t\t\t};\n \t\t};\n \n-\t\tsmartreflex_core: smartreflex@4a0dd000 {\n-\t\t\tcompatible = \"ti,omap4-smartreflex-core\";\n-\t\t\treg = <0x4a0dd000 0x80>;\n-\t\t\tinterrupts = ;\n+\t\ttarget-module@4a0dd000 {\n+\t\t\tcompatible = \"ti,sysc-sr\";\n \t\t\tti,hwmods = \"smartreflex_core\";\n+\t\t\treg = <0x4a0dd000 0x4>,\n+\t\t\t <0x4a0dd008 0x4>;\n+\t\t\treg-names = \"rev\", \"sysc\";\n+\t\t\tclocks = <&l4_ao_clkctrl OMAP4_SMARTREFLEX_CORE_CLKCTRL 0>;\n+\t\t\tclock-names = \"clkctrl\";\n+\t\t\t#address-cells = <1>;\n+\t\t\t#size-cells = <1>;\n+\t\t\tranges = <0 0x4a0dd000 0x001000>;\n+\n+\t\t\tsmartreflex_core: smartreflex@0 {\n+\t\t\t\tcompatible = \"ti,omap4-smartreflex-core\";\n+\t\t\t\treg = <0 0x80>;\n+\t\t\t\tinterrupts = ;\n+\t\t\t};\n \t\t};\n \n-\t\tsmartreflex_mpu: smartreflex@4a0d9000 {\n-\t\t\tcompatible = \"ti,omap4-smartreflex-mpu\";\n-\t\t\treg = <0x4a0d9000 0x80>;\n-\t\t\tinterrupts = ;\n+\t\ttarget-module@4a0d9000 {\n+\t\t\tcompatible = \"ti,sysc-sr\";\n \t\t\tti,hwmods = \"smartreflex_mpu\";\n+\t\t\treg = <0x4a0d9000 0x4>,\n+\t\t\t <0x4a0d9008 0x4>;\n+\t\t\treg-names = \"rev\", \"sysc\";\n+\t\t\tclocks = <&l4_ao_clkctrl OMAP4_SMARTREFLEX_MPU_CLKCTRL 0>;\n+\t\t\tclock-names = \"clkctrl\";\n+\t\t\t#address-cells = <1>;\n+\t\t\t#size-cells = <1>;\n+\t\t\tranges = <0 0x4a0d9000 0x001000>;\n+\n+\t\t\tsmartreflex_mpu: smartreflex@0 {\n+\t\t\t\tcompatible = \"ti,omap4-smartreflex-mpu\";\n+\t\t\t\treg = <0 0x80>;\n+\t\t\t\tinterrupts = ;\n+\t\t\t};\n \t\t};\n \n \t\thwspinlock: spinlock@4a0f6000 {\n@@ -676,6 +727,21 @@\n \t\t\t#iommu-cells = <0>;\n \t\t};\n \n+\t\ttarget-module@52000000 {\n+\t\t\tcompatible = \"ti,sysc-type2\";\n+\t\t\tti,hwmods = \"iss\";\n+\t\t\treg = <0x52000000 0x4>,\n+\t\t\t <0x52000010 0x4>;\n+\t\t\treg-names = \"rev\", \"sysc\";\n+\t\t\tclocks = <&iss_clkctrl OMAP4_ISS_CLKCTRL 0>;\n+\t\t\tclock-names = \"clkctrl\";\n+\t\t\t#address-cells = <1>;\n+\t\t\t#size-cells = <1>;\n+\t\t\tranges = <0 0x52000000 0x1000000>;\n+\n+\t\t\t/* No child device binding, driver in staging */\n+\t\t};\n+\n \t\tmmu_ipu: mmu@55082000 {\n \t\t\tcompatible = \"ti,omap4-iommu\";\n \t\t\treg = <0x55082000 0x100>;\n@@ -770,6 +836,62 @@\n \t\t\tstatus = \"disabled\";\n \t\t};\n \n+\t\ttarget-module@40128000 {\n+\t\t\tcompatible = \"ti,sysc-mcasp\";\n+\t\t\tti,hwmods = \"mcasp\";\n+\t\t\treg = <0x40128004 0x4>;\n+\t\t\treg-names = \"sysc\";\n+\t\t\tclocks = <&abe_clkctrl OMAP4_MCASP_CLKCTRL 0>;\n+\t\t\tclock-names = \"clkctrl\";\n+\t\t\t#address-cells = <1>;\n+\t\t\t#size-cells = <1>;\n+\t\t\tranges = <0x00000000 0x40128000 0x1000>, /* MPU */\n+\t\t\t\t <0x49028000 0x49028000 0x1000>; /* L3 */\n+\n+\t\t\t/*\n+\t\t\t * Child device unsupported by davinci-mcasp.
