powerpc/rcpm: add RCPM driver

2016-03-05T05:50:27Z

There is a RCPM (Run Control/Power Management) in Freescale QorIQ series processors. The device performs tasks associated with device run control and power management. The driver implements some features: mask/unmask irq, enter/exit low power states, freeze time base, etc. Signed-off-by: Chenhui Zhao Signed-off-by: Tang Yuantian [scottwood: remove __KERNEL__ ifdef] Signed-off-by: Scott Wood

QE: Move QE from arch/powerpc to drivers/soc

2015-12-22T23:12:56Z

ls1 has qe and ls1 has arm cpu. move qe from arch/powerpc to drivers/soc/fsl to adapt to powerpc and arm Signed-off-by: Zhao Qiang Signed-off-by: Scott Wood

QE/CPM: move muram management functions to qe_common

2015-12-22T23:10:18Z

QE and CPM have the same muram, they use the same management functions. Now QE support both ARM and PowerPC, it is necessary to move QE to "driver/soc", so move the muram management functions from cpm_common to qe_common for preparing to move QE code to "driver/soc" Signed-off-by: Zhao Qiang Signed-off-by: Scott Wood

powerpc/pasemi: Only the build the pasemi MSI code for PASEMI=y

2015-05-11T09:55:25Z

The pasemi MSI code is currently always built when MPIC=y && PCI_MSI=y. It should not have any effect on other platforms, because it immediately checks the MPIC's compatible property for "pasemi,pwrficient-openpic". However it's odd that it's still built even when PASEMI=n. It also needn't be in sysdev, as it's only used by pasemi. So move it into platforms/pasemi, whereby it will only be built for PASEMI=y.

powerpc: Added PCI MSI support using the HSTA module

2014-04-30T22:26:30Z

The PPC476GTR SoC supports message signalled interrupts (MSI) by writing to special addresses within the High Speed Transfer Assist (HSTA) module. This patch adds support for PCI MSI with a new system device. The DMA window is also updated to allow access to the entire 42-bit address range to allow PCI devices write access to the HSTA module.

driver/memory:Move Freescale IFC driver to a common driver

2014-02-18T20:20:45Z

Freescale IFC controller has been used for mpc8xxx. It will be used for ARM-based SoC as well. This patch moves the driver to driver/memory and fix the header file includes. Also remove module_platform_driver() and instead call platform_driver_register() from subsys_initcall() to make sure this module has been loaded before MTD partition parsing starts.

powerpc/fsl: add MPIC timer wakeup support

2013-07-01T23:38:42Z

The driver provides a way to wake up the system by the MPIC timer. For example, echo 5 > /sys/devices/system/mpic/timer_wakeup echo standby > /sys/power/state After 5 seconds the MPIC timer will generate an interrupt to wake up the system.

powerpc/mpic: add global timer support

2013-07-01T23:38:41Z

The MPIC global timer is a hardware timer inside the Freescale PIC complying with OpenPIC standard. When the specified interval times out, the hardware timer generates an interrupt. The driver currently is only tested on fsl chip, but it can potentially support other global timers complying to OpenPIC standard. The two independent groups of global timer on fsl chip, group A and group B, are identical in their functionality, except that they appear at different locations within the PIC register map. The hardware timer can be cascaded to create timers larger than the default 31-bit global timers. Timer cascade fields allow configuration of up to two 63-bit timers. But These two groups of timers cannot be cascaded together. It can be used as a wakeup source for low power modes. It also could be used as periodical timer for protocols, drivers and etc. Signed-off-by: Wang Dongsheng Signed-off-by: Li Yang Signed-off-by: Scott Wood

powerpc: Add an in memory udbg console

2013-05-07T20:36:49Z

This patch adds a new udbg early debug console which utilises statically defined input and output buffers stored within the kernel BSS. It is primarily designed to assist with bring up of new hardware which may not have a working console but which has a method of reading/writing kernel memory. This version incorporates comments made by Ben H (thanks!). Changes from v1: - Add memory barriers. - Ensure updating of read/write positions is atomic.

Merge remote-tracking branch 'agust/next' into next

2013-02-20T00:39:05Z

<< Please pull mpc5xxx patches for v3.9. The bestcomm driver is moved to drivers/dma (so it will be usable for ColdFire). mpc5121 now provides common dtsi file and existing mpc5121 device trees use it. There are some minor clock init and sparse fixes and updates for various 5200 device tree files from Grant. Some fixes for bugs in the mpc5121 DIU driver are also included here (Andrew Morton suggested to push them via my mpc5xxx tree). >>
