| | * dmaengine: at_hdmac: add DMA slave transfersNicolas Ferre2009-07-231-0/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch for at_hdmac adds the slave transfers capability to the Atmel DMA controller available on some AT91 SOCs. This allow peripheral to memory and memory to peripheral transfers with hardware handshaking. Slave structure for controller specific information is passed through channel private data. This at_dma_slave structure is defined in at_hdmac.h header file and relative hardware definition are moved to this file from at_hdmac_regs.h. Doing this we allow the channel configuration from platform definition code. This work is intensively based on dw_dmac and several slave implementations.

| | * dmaengine: at_hdmac: new driver for the Atmel AHB DMA ControllerNicolas Ferre2009-07-231-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This AHB DMA Controller (aka HDMA or DMAC on AT91 systems) is availlable on at91sam9rl chip. It will be used on other products in the future. This first release covers only the memory-to-memory tranfer type. This is the only tranfer type supported by this chip. On other products, it will be used also for peripheral DMA transfer (slave API support to come). I used dmatest client without problem in different configurations to test it.

* / [ARM] 5438/1: AT91: manage clock by functionality instead of CPUsNicolas Ferre2009-04-281-6/+20
|/ | | | | | | | | | | | | | | In clock.c file the clock management is grouped by cpu with cpu_is_xxx() function. This lead to some kind of difficulties to read this file and maintainability issues as the number of AT91 cpus & PLLs/clocks is growing. In this patch, I try to group clock functionality together and match cpus with this functionality set. An update to at91_pmc.h is needed to cover some new PMC possibilities (and some update in comments).

* [ARM] 5445/1: AT91: Remove flexible array from USBH platform dataJustin Waters2009-04-081-1/+1
| | | | | | | | | | | | | | | | | | The flexible array in the USBH platform data is not safe to copy. The compiler will not allocate any extra memory for the non-init platform data structure (in the *_devices.c files) since it isn't given any defaults at compile time. When the probe function attempts to address that array, it will actually attempt to access data in an adjacent structure. Since there are currently no (known) implementations of the at91 USBH IP with more than 2 vbus pins, I am capping the value at 2. If somebody tries to assign more, then the compiler will produce a warning.

* [ARM] pass reboot command line to arch_reset()Russell King2009-03-191-1/+1
| | | | | | | | | | | | | | | OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

* [ARM] 5319/1: AT91: support AT91CAP9 revC CPUsStelian Pop2008-12-013-1/+25
| | | | | | | | | | | | | | | | | | | | | | | | | The AT91CAP9 revC CPU has a few differences over the previous, revB CPU which was distributed in small quantities only (revA was an internal Atmel product only). This patch adds the detection routines to recognize the different AT91CAP9 revisions (based on the PMC subsystem version number), and uses them to: - activate a workaround for the external interrupts levels (on revB CPUs) - set the UDPHS_BYPASS bit (on revB CPUs) - set AT91_GPBR register address to the correct offset (0xfffffd50 on revB, 0xfffffd60 on revC) For debugging usage, the CPU revision can be found in /proc/cpuinfo on the 'Revision' line. This patch is extracted from Andrew Victor's -at91 patch (2.6.27-at91.patch) where it has been tested for the last 6 months.

* [ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King2008-11-291-19/+0Star
| | | | | | | | | | | | | When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

* [ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre2008-11-281-11/+0Star
| | | | | | | | | | | | | | | | Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.
