| * | ARM: gpio: make trivial GPIOLIB implementation the defaultRussell King2011-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than marking the mach/gpio.h header files which want to use the trivial GPIOLIB implementation, mark those which do not want to use it instead. This means that by default, you get the trivial implementation and only have to do something extra if you need to. This should encourage the use of the trivial default implementation. As an additional bonus, several gpio.h header files become empty.

* AT91: Change nand buswidth logic to match hardware default configurationNicolas Ferre2011-07-04
| | | | | | | | | | | | | | The recently modified nand buswitth configuration is not aligned with board reality: the double footprint on boards is always populated with 8bits buswidth nand flashes. So we have to consider that without particular configuration the 8bits buswidth is selected by default. Moreover, the previous logic was always using !board_have_nand_8bit(), we change it to a simpler: board_have_nand_16bit().

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.

| | | | | | | | | | | | Disable the processor clock when the CPU is idle. This saves much more power than merely entering 'Wait for Interrupt' mode. Since JTAG-debugging doesn't work when the processor clock is switched off, make it conditional on CONFIG_DEBUG_KERNEL.

* atmel-mci: change use of dma slave interfaceNicolas Ferre2009-12-15
| | | | | | | | | | | | | | | | | Allow the use of another DMA controller driver in atmel-mci sd/mmc driver. This adds a generic dma_slave pointer to the mci platform structure where we can store DMA controller information. In atmel-mci we use information provided by this structure to initialize the driver (with new helper functions that are architecture dependant). This also adds at32/avr32 chip modifications to cope with this new access method.
