* avr32: clean up memory allocation in at32_add_device_mciHans-Christian Egtvedt2009-12-281-4/+7
| | | | | | | | | | | | This patch will check if the kzalloc for the MCI DMA struct actually returns a valid address, and also clean up properly if it fails or the function fails at a later stage. This also silences a compiler warning about using the slave variable uninitialized.

This adds a generic dma_slave pointer to the mci platform structure where we can store DMA controller information.

It offers versatile peripherals, such as ethernet, usb device, usb host etc. The board also incooperates a power supply and is a Power over Ethernet (PoE) Powered Device (PD). Additonally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which will cover even the most exceptional need of memory bandwidth. Together with the onboard video decoder the board is ready for video processing. This patch does include the basic support for the fpga device driver, but not the device driver itself.

The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for DMA transfers through the generic DMA engine framework with the DMA slave extensions. The driver has been tested using mmc-block and ext3fs on several SD, SDHC and MMC+ cards. Reads and writes work fine, with read transfer rates up to 7.5 MiB/s on fast cards with debugging disabled. Unfortunately, the driver has been known to lock up from time to time with DMA enabled, so DMA support is currently optional and marked EXPERIMENTAL. However, I didn't see any problems while testing 13 different cards (MMC, SD and SDHC of different brands and sizes), so I suspect the "Initialize BLKR before sending data transfer command" fix that was posted earlier fixed this as well.

Currently, the driver will use the first valid slot it finds and stick with that, but later patches will add support for switching between several slots on the fly. Extend the platform data structure with per-slot information: MMC/SDcard bus width and card detect/write protect pins. This will affect the pin muxing as well as the capabilities announced to the mmc core. Note that board code is now required to supply a mci_platform_data struct to at32_add_device_mci().

* | avr32: Use platform_driver_probe for pio platform driverUwe Kleine-König2008-09-221-2/+1
| | | | | | | | | | | | | | | | | | | | | | The probe function of the pio platform driver lives in the init section and so a pio device that is created after the init section is discarded probably results in an oops. Even if this cannot happen, using platform_driver_probe is cleaner. (If this can happen and should be supported the probe function must live in the devinit section instead.)

* | avr32: Provide a way to deselect pins in the portmuxHaavard Skinnemoen2008-09-222-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | Currently, setting up the portmux is completely one-shot: Once a pin is muxed, the portmux driver will complain loudly and refuse to do anything if you try to set up the same pin again. Sometimes, it may be necessary to change the configuration of a pin after it has been set up initially. This patch adds a way to undo the previous configuration, allowing the pin to be reconfigured.

* | avr32: Allow fine-grained control over LCDC pinsJulien May2008-09-223-71/+154
| | | | | | | | | | | | | | | | | | | | This replaces the pin_config param with an u64 pin_mask in at32_add_device_lcdc, allowing a board-maintainer to indivually select specific lcdc pins.

* avr32: pm_standby low-power ram bug fixHumphrey Bucknell2008-09-011-1/+1
| | | | | | | | | | | | The value stored into the SDRAMC LPR register should be the current value of the register with the Self-refresh value set in the lower bit field. The bug involved only the Self-refresh value being written to the register, thus over writing any low-power ram settings.

* avr32: Clean up HMATRIX codeHaavard Skinnemoen2008-08-086-201/+180
| | | | | | | | | | | Introduce a few helper functions for HMATRIX configuration and clean up the register definitions. Also add definitions for the HMATRIX master and slave IDs on the AT32AP700x chips. Also make the definitions in hmatrix.h available to board code by moving it to <mach/hmatrix.h> Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* avr32: Add MMIO address definitions for certain controllersHaavard Skinnemoen2008-08-084-13/+13
| | | | | | | | Hardcoded MMIO base addresses are used a few places throughout the platform code. Move these into the chip-specific header file so that adding support for new chips becomes a bit easier. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* avr32: Introduce <mach/chip.h>Haavard Skinnemoen2008-08-081-0/+19
| | | | | | | | | This file includes the appropriate chip-specific header with MMIO, IRQ and GPIO definitions used by the platform code. It may also be used to provide inline GPIO accessors for drivers that are willing to sacrifice portability for faster bitbanging. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
