gpio: move mpc8xxx/512x gpio driver to drivers/gpio

2011-09-22T22:14:15Z

Move the driver to the place where it is expected to be nowadays. Also rename its CONFIG-name to match the rest and adapt the defconfigs. Finally, move selection of REQUIRE_GPIOLIB or WANTS_OPTIONAL_GPIOLIB to the platforms, because this option is per-platform and not per-driver.

powerpc: introduce the ePAPR embedded hypervisor vmpic driver

2011-06-27T13:30:26Z

The Freescale ePAPR reference hypervisor provides interrupt controller services via a hypercall interface, instead of emulating the MPIC controller. This is called the VMPIC. The ePAPR "virtual interrupt controller" provides interrupt controller services for external interrupts. External interrupts received by a partition can come from two sources: - Hardware interrupts - hardware interrupts come from external interrupt lines or on-chip I/O devices. - Virtual interrupts - virtual interrupts are generated by the hypervisor as part of some hypervisor service or hypervisor-created virtual device. Both types of interrupts are processed using the same programming model and same set of hypercalls. Signed-off-by: Ashish Kalra Signed-off-by: Timur Tabi Signed-off-by: Kumar Gala

powerpc/4xx: Adding PCIe MSI support

powerpc: Add SCOM infrastructure

2011-04-20T07:01:19Z

SCOM is a side-band configuration bus implemented on some processors. This code provides a way for code to map and operate on devices via SCOM, while the details of how that is implemented is left up to a SCOM "controller" in the platform code.

powerpc/xics: Rewrite XICS driver

2011-04-20T01:02:35Z

This is a significant rework of the XICS driver, too significant to conveniently break it up into a series of smaller patches to be honest. The driver is moved to a more generic location to allow new platforms to use it, and is broken up into separate ICP and ICS "backends". For now we have the native and "hypervisor" ICP backends and one common RTAS ICS backend. The driver supports one ICP backend instanciation, and many ICS ones, in order to accomodate future platforms with multiple possibly different interrupt "sources" mechanisms.

rapidio: modify configuration to support PCI-SRIO controller

2011-03-24T02:46:42Z

1. Add an option to include RapidIO support if the PCI is available. 2. Add FSL_RIO configuration option to enable controller selection. 3. Add RapidIO support option into x86 and MIPS architectures.

powerpc/4xx: Add suspend and idle support

2010-11-29T15:05:06Z

Add suspend/resume support for 4xx compatible CPUs. See /sys/power/state for available power states configured in. Add two different idle states (idle-wait and idle-doze) controlled via sysfs. Default is idle-wait. cat /sys/devices/system/cpu/cpu0/idle [wait] doze To save additional power, use idle-doze. echo doze > /sys/devices/system/cpu/cpu0/idle cat /sys/devices/system/cpu/cpu0/idle wait [doze] Signed-off-by: Victor Gallardo Signed-off-by: Josh Boyer

powerpc/85xx: add cache-sram support

2010-10-14T05:54:38Z

It adds cache-sram support in P1/P2 QorIQ platforms as under: * A small abstraction over powerpc's remote heap allocator * Exports mpc85xx_cache_sram_alloc()/free() APIs * Supports only one contiguous SRAM window * Drivers can do the following in Kconfig to use these APIs "select FSL_85XX_CACHE_SRAM if MPC85xx" * Required SRAM size and the offset where SRAM should be mapped must be provided at kernel command line as : cache-sram-size= cache-sram-offset= Signed-off-by: Harninder Rai Signed-off-by: Vivek Mahajan Signed-off-by: Kumar Gala

powerpc/85xx/86xx: Add suspend/resume support

2009-11-12T03:43:28Z

This patch adds suspend/resume support for MPC8540 and MPC8641D- compatible CPUs. To reach sleep state, we just write the SLP bit into the PM control and status register. So far we don't support Deep Sleep mode as found in newer MPC85xx CPUs (i.e. MPC8536). It can be relatively easy implemented though, and for it we reserve 'mem' suspend type.
