| * avr32: Fix GPIO initcall breakageHaavard Skinnemoen2008-10-231-2/+0
| | | | | | | | | | | | | | | | | | | | Add essential system devices, including GPIO controllers, automatically at core_initcall time. This ensures that the devices are there when the PIO driver gets initialized at postcore_initcall, fixing a bug exposed by commit d6634db8fe1784d0a8e4e156970fec034708446e "avr32: Use platform_driver_probe for pio platform driver".

* | avr32: Add support for EVKLCD10X addon boardsHans-Christian Egtvedt2008-10-134-1/+197
|/ | | | | | | | | | | | | | | | | | | | | | | This patch lets the user enable support for EVKLCD100 and EVKLCD101 (refered to by EVKLCD10X). By enabling EVKLCD10X support the LCD controller and AC97 controller platform devices are added. The user can also choose between the EVKLCD100 (QVGA display) and the EVKLCD101 (VGA display), this is added to automagically select the correct panel timing and resolution parameters. Enabling support for EVKLCD10X addon board will cripple the MCI platform device a bit since they share two GPIO lines (detect and write-protect). These two lines are disabled when EVKLCD10X is enabled. The default configurations are based upon ATNGW100, but with added AC97C and LCDC driver. Virtual terminal is also enabled by default for EVKLCD10X boards. Verified on hardware with a NGW100 + EVKLCD100/101.

| * atmel-mci: Platform code for supporting multiple mmc slotsHaavard Skinnemoen2008-10-051-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

* | ngw100: export J15 through sysfsDavid Brownell2008-09-221-0/+10
|/ | | | | | | | | | | | The NGW100 board has jumper J15 (near the reset button) which is unused. This patch exports it through the GPIO sysfs support (as /sys/class/gpio/gpio62/value) so that it's easily queried by boot scripts or whatever might want to know if the jumper has been installed (value = 0) or not (value = 1, "default").

| | | | | | | | Doing this in combination with "atmel_spi: fix hang due to missed interrupt" appears to eliminate the overruns I'm seeing when using JFFS2-on-DataFlash as /usr filesystem on the ATNGW100. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>

* atmel-mci: Driver for Atmel on-chip MMC controllersHaavard Skinnemoen2008-07-151-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a driver for the MMC controller on the AP7000 chips from Atmel. It should in theory work on AT91 systems too with some tweaking, but since the DMA interface is quite different, it's not entirely clear if it's worth merging this with the at91_mci driver. This driver has been around for a while in BSPs and kernel sources provided by Atmel, but this particular version uses the generic DMA Engine framework (with the slave extensions) instead of an avr32-only DMA controller framework. This driver can also use PIO transfers when no DMA channels are available, and for transfers where using DMA may be difficult or impractical for some reason (e.g. the DMA setup overhead is usually not worth it for very short transfers, and badly aligned buffers or lengths are difficult to handle.) Currently, the driver only support PIO transfers. DMA support has been split out to a separate patch to hopefully make it easier to review. 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 3.5 MiB/s on fast cards with debugging disabled. The driver has also been tested using the mmc_test module on the same cards. All tests except 7, 9, 15 and 17 succeed. The first two are unsupported by all the cards I have, so I don't know if the driver handles this correctly. The last two fail because the hardware flags a Data CRC Error instead of a Data Timeout error. I'm not sure how to deal with that. Documentation for this controller can be found in many data sheets from Atmel, including the AT32AP7000 data sheet which can be found here: http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* avr32: improve NGW100 I2C/PMBus setupDavid Brownell2008-06-271-0/+22
| | | | | | | | | | | | Basic I2C initialization for the NGW100 board: - Provide empty i2c device table. Daughtercards may add devices, and the ATtiny24 could do stuff too. - Set up EXTINT(3) so the ATtiny24 can interrupt the AP7000.

* avr32: Allow board to define oscillator ratesAlex2008-06-271-0/+7
| | | | | | | | | | | | On our custom board we have other oscillator rates than on atngw100 and atstk100x. Currently these rates are hardcoded in arch/avr32/mach-at32ap/at32ap700x.c. This patch moves them into board specific code. Signed-off-by: Alex Raimondi <raimondi@miromico.ch> Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* [AVR32] Add support for AT32AP7001 and AT32AP7002Haavard Skinnemoen2008-01-251-1/+1
| | | | | | | | | These are derivatives of the AT32AP7000 chip, which means that most of the code stays the same. Rename a few files, functions, definitions and config symbols to reflect that they apply to all AP700x chips, and exclude some platform devices from chips where they aren't present.

* [AVR32] ngw100 i2c-gpio tweaksDavid Brownell2007-10-111-4/+9
| | | | | | | | | | | | | Make the NGW100 bitbang i2c use open drain signaling. Also, speed it up, so it's closer to 100 kHz ... the code paths seem to be long enough that the udelay isn't dominating bit times. The peak bit rate I observed was around 125 kHz, but that's with large delays (usually before ACK/NAK) which hold the overall rate down to around 80 kHz (call it 100 usec/byte on average).
