Hi, I run into this message "Ran out of outbound PCI ATMUs for IO resource". The only solution I found so far is to replace few lines in this way: pci0: pcie@f1008000 { reg = <0xf1008000 0x1000>; - ranges = <0x0200 0x0 0x8000 0x8000 0x0 0x1000 - 0x4200 0x0 0x

[PATCH v2 1/5] powerpc/85xx: support sleep feature on QorIQ SoCs with RCPM

2016-04-15 Thread Chenhui Zhao
In sleep mode, the clocks of e500 cores and unused IP blocks is turned off. The IP blocks which are allowed to wake up the processor are still running. The sleep mode is equal to the Standby state in Linux. Use the command to enter sleep mode: echo standby > /sys/power/state Signed-off-by: Chen

[PATCH v2 4/5] powerpc/pm: support deep sleep feature on T104x

2016-04-15 Thread Chenhui Zhao
T104x has deep sleep feature, which can switch off most parts of the SoC when it is in deep sleep mode. This way, it becomes more energy-efficient. The DDR controller will also be powered off in deep sleep. Therefore, the last stage (the latter part of fsl_dp_enter_low) will run without DDR access

[PATCH v2 0/5] powerpc/pm: QorIQ deep sleep

2016-04-15 Thread Chenhui Zhao
Changes for v2: * Ioremap every dts node used in the patches. * Check the board compatible string to see if the board supports deep sleep. * Can not reserve the first page of DDR memory, because PPC64 doesn't support changing the kernel base address. So still save and restore the first 128 bytes

[PATCH v2 2/5] powerpc: pm: add EPU FSM configuration for deep sleep

2016-04-15 Thread Chenhui Zhao
In the last stage of deep sleep, software will trigger a Finite State Machine (FSM) to control the hardware precedure, such as board isolation, killing PLLs, removing power, and so on. When the system is waked up by an interrupt, the FSM controls the hardware to complete the early resume precedure
