ARM: omap: convert wakeupgen to stacked domains OMAP4/5 has been (ab)using the gic_arch_extn to provide wakeup from suspend, and it makes a lot of sense to convert this code to use stacked domains instead. This patch does just this, updating the DT files to actually reflect what the HW provides. BIG FAT WARNING: because the DTs were so far lying by not exposing the WUGEN HW block, kernels with this patch applied won't have any suspend-resume facility when booted with old DTs, and old kernels with updated DTs won't even boot. On a platform with this patch applied, the system looks like this: root@bacon-fat:~# cat /proc/interrupts CPU0 CPU1 16: 0 0 WUGEN 37 gp_timer 19: 233799 155916 GIC 27 arch_timer 23: 0 0 WUGEN 9 l3-dbg-irq 24: 1 0 WUGEN 10 l3-app-irq 27: 282 0 WUGEN 13 omap-dma-engine 44: 0 0 4ae10000.gpio 13 DMA 294: 0 0 WUGEN 20 gpmc 297: 506 0 WUGEN 56 48070000.i2c 298: 0 0 WUGEN 57 48072000.i2c 299: 0 0 WUGEN 61 48060000.i2c 300: 0 0 WUGEN 62 4807a000.i2c 301: 8 0 WUGEN 60 4807c000.i2c 308: 2439 0 WUGEN 74 OMAP UART2 312: 362 0 WUGEN 83 mmc2 313: 502 0 WUGEN 86 mmc0 314: 13 0 WUGEN 94 mmc1 350: 0 0 PRCM pinctrl, pinctrl 406: 35155709 0 GIC 109 ehci_hcd:usb1 407: 0 0 WUGEN 7 palmas 409: 0 0 WUGEN 119 twl6040 410: 0 0 twl6040 5 twl6040_irq_ready 411: 0 0 twl6040 0 twl6040_irq_th IPI0: 0 1 CPU wakeup interrupts IPI1: 0 0 Timer broadcast interrupts IPI2: 95334 902334 Rescheduling interrupts IPI3: 0 0 Function call interrupts IPI4: 479 648 Single function call interrupts IPI5: 0 0 CPU stop interrupts IPI6: 0 0 IRQ work interrupts IPI7: 0 0 completion interrupts Err: 0 Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Link: https://lkml.kernel.org/r/1426088629-15377-8-git-send-email-marc.zyngier@arm.com Signed-off-by: Jason Cooper <jason@lakedaemon.net>

ARM: dts: am4372: Add the PRU-ICSS1 DT node Add the DT node for the PRU-ICSS1 instance on the AM437x family of SoCs. Each PRU-ICSS instance is represented by a pruss node and other child nodes. The nodes are added under the interconnect target module node in the common am4372 dtsi file. The PRU-ICSS instances are supported only on AM4376+ SoCs though in the AM437x family, so the interconnect target module node should be disabled in any derivative board dts file that uses AM4372 SoCs. The PRU-ICSS1 on AM437x is very similar to the PRUSS in AM33xx, except for variations in the RAM sizes, bus addresses and the number of interrupts coming into the MPU INTC (host interrupt 5 is routed to the other PRUSS instead of MPU). The PRUSS subsystem node contains the entire address space. The various sub-modules of the PRU-ICSS are represented as individual child nodes (so platform devices themselves) of the PRUSS subsystem node. These include the two PRU cores and the interrupt controller. All the Data RAMs are represented within a child node of its own named 'memories' without any compatible. The Real Time Media Independent Interface controller (MII_RT), and the CFG sub-module are represented as syscon nodes. The PRUSS CFG module has a clock mux for IEP clock, this clk node is added under the CFG child node 'clocks'. The default source for this mux clock is the PRU_ICSS_IEP_GCLK clock. The DT nodes use all standard properties. The regs property in the PRU nodes define the addresses for the Instruction RAM, the Debug and Control sub-modules for that PRU core. The firmware for each PRU core is defined through a 'firmware-name' property. The default names for the firmware images for each PRU core are defined as follows (these can be adjusted either in derivative board dts files or through sysfs at runtime if required): PRU-ICSS1 PRU0 Core: am437x-pru1_0-fw PRU-ICSS1 PRU1 Core: am437x-pru1_1-fw Note: 1. There are few more sub-modules like the Industrial Ethernet Peripheral (IEP), MDIO, UART, eCAP that do not have bindings and so will be added in the future. 2. The PRUSS INTC on AM437x SoCs also connect the host interrupt 0 to ADC0 and ADC1; 6 and 7 as possible DMA events, so use the 'ti,irqs-reserved' property in derivative board dts files _if_ any of them should not be handled by the host OS. Host interrupt 5 is already marked reserved as it is connected to the other PRUSS instance. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

ARM: dts: am4372: Add the PRU-ICSS1 DT node Add the DT node for the PRU-ICSS1 instance on the AM437x family of SoCs. Each PRU-ICSS instance is represented by a pruss node and other child nodes. The nodes are added under the interconnect target module node in the common am4372 dtsi file. The PRU-ICSS instances are supported only on AM4376+ SoCs though in the AM437x family, so the interconnect target module node should be disabled in any derivative board dts file that uses AM4372 SoCs. The PRU-ICSS1 on AM437x is very similar to the PRUSS in AM33xx, except for variations in the RAM sizes, bus addresses and the number of interrupts coming into the MPU INTC (host interrupt 5 is routed to the other PRUSS instead of MPU). The PRUSS subsystem node contains the entire address space. The various sub-modules of the PRU-ICSS are represented as individual child nodes (so platform devices themselves) of the PRUSS subsystem node. These include the two PRU cores and the interrupt controller. All the Data RAMs are represented within a child node of its own named 'memories' without any compatible. The Real Time Media Independent Interface controller (MII_RT), and the CFG sub-module are represented as syscon nodes. The PRUSS CFG module has a clock mux for IEP clock, this clk node is added under the CFG child node 'clocks'. The default source for this mux clock is the PRU_ICSS_IEP_GCLK clock. The DT nodes use all standard properties. The regs property in the PRU nodes define the addresses for the Instruction RAM, the Debug and Control sub-modules for that PRU core. The firmware for each PRU core is defined through a 'firmware-name' property. The default names for the firmware images for each PRU core are defined as follows (these can be adjusted either in derivative board dts files or through sysfs at runtime if required): PRU-ICSS1 PRU0 Core: am437x-pru1_0-fw PRU-ICSS1 PRU1 Core: am437x-pru1_1-fw Note: 1. There are few more sub-modules like the Industrial Ethernet Peripheral (IEP), MDIO, UART, eCAP that do not have bindings and so will be added in the future. 2. The PRUSS INTC on AM437x SoCs also connect the host interrupt 0 to ADC0 and ADC1; 6 and 7 as possible DMA events, so use the 'ti,irqs-reserved' property in derivative board dts files _if_ any of them should not be handled by the host OS. Host interrupt 5 is already marked reserved as it is connected to the other PRUSS instance. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

ARM: dts: am4372: Add the PRU-ICSS0 DT node The AM4376+ SoCs have a second smaller PRU-ICSS subsystem (PRUSS0) in addition to the primary PRUSS1 instance. The PRUSS0 has less DRAM per PRU, and no Shared DRAM among other minor differences. The IEP and MII_RT modules even though present within the IP are not pinned out. This PRUSS0 instance has a weird SoC integration. It shares the same L3 OCP interconnect interface with PRUSS1, and also shares its reset line and clocks. Any external accesses from PRUSS0 requires the PRUSS1's PRUSS_SYSCFG register to be programmed properly. That said, it is its own IP instance (a cut-down version), and so it has been added as an independent node (sibling node to PRUSS1 node) and a child node of the corresponding PRUSS target module interconnect node. This allows the PRUSS0 instance to be enabled/disabled independently of the PRUSS1 instance. The nodes are added under the corresponding interconnect target module node in the common am4372 dtsi file. The PRU-ICSS instances are not supported on AM4372 SoC though in the AM437x family, so the interconnect target module node should be disabled in any derivative board dts file that uses AM4372 SoCs. The individual PRUSS node can be disabled in the corresponding board dts file if desired. The default names for the firmware images for each PRU core are defined as follows (these can be adjusted either in derivative board dts files or through sysfs at runtime if required): PRU-ICSS0 PRU0 Core: am437x-pru0_0-fw PRU-ICSS0 PRU1 Core: am437x-pru0_1-fw Note: 1. There are few more sub-modules like the Industrial Ethernet Peripheral (IEP), eCAP, UART, that do not have bindings and so will be added in the future. Only UART is pinned out, so others should be added in disabled state if added. 2. The PRUSS0 INTC on AM437x SoCs routes the host interrupt 5 to the other PRUSS1, so it is already marked reserved through the 'ti,irqs-reserved' property.
