* mmc: at91_mci: fix multiblock SDIO transfersYauhen Kharuzhy2010-12-211-0/+2
| | | | | | | | | | | | | | | | | | | The AT91 MCI has special SDIO transfer types: SDIO block and SDIO byte transfers, but at91_mci driver doesn't use them and handles all SDIO transfers as ordinary MMC block transfers. This causes problems for multiple-block SDIO transfers (in particular for 256-bytes blocks). Fix this situation by checking the opcode for SDIO CMD53 and setting the transfer type in the AT91_MCI_CMDR register properly. This patch was tested with libertas SDIO driver: problem with TX timeouts on big packets was eliminated.

* arm: return both physical and virtual addresses from addruartJeremy Kerr2010-10-201-5/+3
| | | | | | | | | | | | | | | | | | | | Rather than checking the MMU status in every instance of addruart, do it once in kernel/debug.S, and change the existing addruart macros to return both physical and virtual addresses. The main debug code can then select the appropriate address to use. This will also allow us to retreive the address of a uart for the MMU state that we're not current in.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | According to Atmel, their 926T processors (AT91 post RM9200) requires 'Wait for Interrupt' mode be entered right after disabling the processor clock in order to minimise current consumption when idle, so do both provided we're not running on a 920T (an RM9200). Furthermore, get rid of the #ifndef CONFIG_DEBUG_KERNEL, since arch_idle() can be turned off completely with the kernel parameter 'nohlt'.

| * dmaengine: at_hdmac: add DMA slave transfersNicolas Ferre2009-07-221-0/+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 Ferre2009-07-221-0/+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. Full documentation for this controller can be found in the SAM9RL datasheet: http://www.atmel.com/dyn/products/product_card.asp?part_id=4243 Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
* | [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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is IDE host driver for AT91 (SAM9, CAP9, AT572D940HF) Static Memory Controller with Compact Flash True IDE Mode logic. Driver have to switch 8/16 bit bus width when accessing Task Tile or Data Register. Moreover some extra things need to be done when setting PIO mode. Only PIO mode is used, hardware have no DMA support. If interrupt line is connected through GPIO extra quirk is needed to cope with fake interrupts.
