      avr32: function for independently setting up SPI slaves · 07084203
      由 Peter Ma 提交于 
      at32ap_spi_setup_slaves() is exposed to allow the addition of SPI slaves
to a SPI bus that has already been registered.  This is especially
useful for add-on cards, which have their own board setup function.
at32ap_spi_add_device() has been slightly re-organized, but should be
transparent to existing users.

So to add a SPI slave, after a SPI bus has already been registered:

	/* Configure the list of slaves on SPI controller "id" */
	at32_spi_setup_slaves(id,spi_board_info,ARRAY_SIZE(spi_board_info));
 	/* Register the list of slaves */
 	spi_register_board_info(spi_board_info,ARRAY_SIZE(spi_board_info));

      avr32: Hammerhead board support · dd5e1339
      由 Alex Raimondi 提交于 
      The Hammerhead platform is built around a AVR32 32-bit microcontroller
from Atmel.  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.

      avr32: Allow reserving multiple pins at once · adde42b5
      由 Alex Raimondi 提交于 
      at32_reserve_pin now takes an u32 bitmask rather than a single pin.
This allows to reserve multiple pins at once.

      avr: struct device - replace bus_id with dev_name(), dev_set_name() · 5f6333bd
      由 Kay Sievers 提交于 
      (I did not compile or test it, please let me know, or help fixing
 it, if something is wrong with the conversion)

This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. 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.

Thanks,
Kay

      atmel-mci: Add experimental DMA support · 65e8b083
      由 Haavard Skinnemoen 提交于 
      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.

      atmel-mci: Platform code for supporting multiple mmc slots · 6b918657
      由 Haavard Skinnemoen 提交于 
      Add the necessary platform infrastructure to support multiple mmc/sdcard
slots all at once through a single controller. 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().
