* [ARM] 4495/1: iop: combined watchdog timer driver for iop3xx and iop13xxDan Williams2007-07-20
| | | | | | | | | | | | | | | | | | | In order for this driver to be shared across the iop architectures the iop3xx and iop13xx header files are modified to present a common interface for the iop_wdt driver. Details: * iop13xx supports disabling the timer while iop3xx does not. This requires a few 'compatibility' definitions in include/asm-arm/hardware/iop3xx.h to preclude adding #ifdef CONFIG_ARCH_IOP13XX blocks to the driver code. * The heartbeat interval is derived from the internal bus clock rate, so this this patch also exports the tick rate to the iop_wdt driver.

* iop3xx: surface the iop3xx DMA and AAU units to the iop-adma driverDan Williams2007-07-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | Adds the platform device definitions and the architecture specific support routines (i.e. register initialization and descriptor formats) for the iop-adma driver. Changelog: * add support for > 1k zero sum buffer sizes * added dma/aau platform devices to iq80321 and iq80332 setup * fixed the calculation in iop_desc_is_aligned * support xor buffer sizes larger than 16MB * fix places where software descriptors are assumed to be contiguous, only hardware descriptors are contiguous for up to a PAGE_SIZE buffer size * convert to async_tx * add interrupt support * add platform devices for 80219 boards * do not call platform register macros in driver code * remove switch() statements for compatible register offsets/layouts * change over to bitmap based capabilities * remove unnecessary ARM assembly statement * checkpatch.pl fixes * gpl v2 only correction * phys move to dma_async_tx_descriptor Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
* dmaengine: driver for the iop32x, iop33x, and iop13xx raid enginesDan Williams2007-07-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Intel(R) IOP series of i/o processors integrate an Xscale core with raid acceleration engines. The capabilities per platform are: iop219: (2) copy engines iop321: (2) copy engines (1) xor and block fill engine iop33x: (2) copy and crc32c engines (1) xor, xor zero sum, pq, pq zero sum, and block fill engine iop34x (iop13xx): (2) copy, crc32c, xor, xor zero sum, and block fill engines (1) copy, crc32c, xor, xor zero sum, pq, pq zero sum, and block fill engine The driver supports the features of the async_tx api: * asynchronous notification of operation completion * implicit (interupt triggered) handling of inter-channel transaction dependencies The driver adapts to the platform it is running by two methods. 1/ #include <asm/arch/adma.h> which defines the hardware specific iop_chan_* and iop_desc_* routines as a series of static inline functions 2/ The private platform data attached to the platform_device defines the capabilities of the channels 20070626: Callbacks are run in a tasklet. Given the recent discussion on LKML about killing tasklets in favor of workqueues I did a quick conversion of the driver. Raid5 resync performance dropped from 50MB/s to 30MB/s, so the tasklet implementation remains until a generic softirq interface is available. Changelog: * fixed a slot allocation bug in do_iop13xx_adma_xor that caused too few slots to be requested eventually leading to data corruption * enabled the slot allocation routine to attempt to free slots before returning -ENOMEM * switched the cleanup routine to solely use the software chain and the status register to determine if a descriptor is complete. This is necessary to support other IOP engines that do not have status writeback capability * make the driver iop generic * modified the allocation routines to understand allocating a group of slots for a single operation * added a null xor initialization operation for the xor only channel on iop3xx * support xor operations on buffers larger than the hardware maximum * split the do_* routines into separate prep, src/dest set, submit stages * added async_tx support (dependent operations initiation at cleanup time) * simplified group handling * added interrupt support (callbacks via tasklets) * brought the pending depth inline with ioat (i.e. 4 descriptors) * drop dma mapping methods, suggested by Chris Leech * don't use inline in C files, Adrian Bunk * remove static tasklet declarations * make iop_adma_alloc_slots easier to read and remove chances for a corrupted descriptor chain * fix locking bug in iop_adma_alloc_chan_resources, Benjamin Herrenschmidt * convert capabilities over to dma_cap_mask_t * fixup sparse warnings * add descriptor flush before iop_chan_enable * checkpatch.pl fixes * gpl v2 only correction * move set_src, set_dest, submit to async_tx methods * move group_list and phys to async_tx Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

* [ARM] 4348/4: iop3xx: Give Linux control over PCI initializationDan Williams2007-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | Currently the iop3xx platform support code assumes that RedBoot is the bootloader and has already initialized the ATU. Linux should handle this initialization for three reasons: 1/ The memory map that RedBoot sets up is not optimal (page_to_dma and virt_to_phys return different addresses). The effect of this is that using the dma mapping API for the internal bus dma units generates pci bus addresses that are incorrect for the internal bus. 2/ Not all iop platforms use RedBoot 3/ If the ATU is already initialized it indicates that the iop is an add-in card in another host, it does not own the PCI bus, and should not be re-initialized.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Lubbock platform uses both a PXA25x and a SA1111 at the same time. Both chips have the same "Serial Audio Controller" registers although the SA1111 one is never expected to be used in preference to the PXA25x one. So let's disable the SA1111 defines whenever compilation is for a PXA architecture and make the PXA defines always defined. This removes a bunch of "already defined" warnings as well since the current hack to prevent them depended on include ordering which wasn't always right. While at it, clean up the SA1111 defines allowing to get rid of the __CCREG() macro. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | This is needs to be visible to other architectures using the AMBA bus and peripherals. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Move AMBA include files to include/linux/amba/Russell King2006-01-07
| | | | | | | | | Since the ARM AMBA bus is used on MIPS as well as ARM, we need to make the bus available for other architectures to use. Move the AMBA include files from include/asm-arm/hardware/ to include/linux/amba/ Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 3228/1: SharpSL: Move PM code to arch/arm/commonRichard Purdie2006-01-05
| | | | | | | | | | | | Patch from Richard Purdie This patch moves a large chunk of the sharpsl_pm driver to arch/arm/common so that it can be reused on other devices such as the SL-5500 (collie). It also abstracts some functions from the core into the machine and platform specific parts of the driver to aid reuse.

* [ARM] Remove clk_use()/clk_unuse()Russell King2006-01-03
| | | | | | | | | It seems that clk_use() and clk_unuse() are additional complexity which isn't required anymore. Remove them from the clock framework to avoid the additional confusion which they cause, and update all ARM machine types except for OMAP. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
