* ARM: at91: drop ide driver in favor of the pata oneJean-Christophe PLAGNIOL-VILLARD2012-02-13
| | | | | | | | | Driver at91_ide is broken and should not be fixed: remove it. Modification of device files that where making use of it. The PATA driver (pata_at91) is able to replace at91_ide.

* at91_ide: remove headers specific for at91sam9263Sergey Matyukevich2009-08-15
| | | | | | | | | | | | This driver requires only static memory controller definitions and macroses contained in generic header at91sam9_smc.h. Those extra headers are misleading since this driver also works fine for at91sam9260 SoC: tests were performed on afeb9260 board.

| | | | | | | | | | | | | | | | | | * Convert host drivers that still use hw_regs_t's chipset field to use the one in struct ide_port_info instead. * Move special handling of ide_pci chipset type from ide_hw_configure() to ide_init_port(). * Remove chipset field from hw_regs_t.

* ide: rename IDE_TFLAG_IN_[HOB_]FEATURESergei Shtylyov2009-03-31
| | | | | | | | | | The feature register has never been readable -- when its location is read, one gets the error register value; hence rename IDE_TFLAG_IN_[HOB_]FEATURE into IDE_TFLAG_IN_[HOB_]ERROR and introduce the 'hob_error' field into the 'struct ide_taskfile' (despite the error register not really depending on the HOB bit).

* ide: add at91_ide driverStanislaw Gruszka2009-03-05
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.
