- * Based in part on the ITE vendor provided SCSI driver.
- *
- * Documentation:
- * Datasheet is freely available, some other documents under NDA.
- *
- * The ITE8212 isn't exactly a standard IDE controller. It has two
- * modes. In pass through mode then it is an IDE controller. In its smart
- * mode its actually quite a capable hardware raid controller disguised
- * as an IDE controller. Smart mode only understands DMA read/write and
- * identify, none of the fancier commands apply. The IT8211 is identical
- * in other respects but lacks the raid mode.
- *
- * Errata:
- * o Rev 0x10 also requires master/slave hold the same DMA timings and
- * cannot do ATAPI MWDMA.
- * o The identify data for raid volumes lacks CHS info (technically ok)
- * but also fails to set the LBA28 and other bits. We fix these in
- * the IDE probe quirk code.
- * o If you write LBA48 sized I/O's (ie > 256 sector) in smart mode
- * raid then the controller firmware dies
- * o Smart mode without RAID doesn't clear all the necessary identify
- * bits to reduce the command set to the one used
- *
- * This has a few impacts on the driver
- * - In pass through mode we do all the work you would expect
- * - In smart mode the clocking set up is done by the controller generally
- * but we must watch the other limits and filter.
- * - There are a few extra vendor commands that actually talk to the
- * controller but only work PIO with no IRQ.
- *
- * Vendor areas of the identify block in smart mode are used for the
- * timing and policy set up. Each HDD in raid mode also has a serial
- * block on the disk. The hardware extra commands are get/set chip status,
- * rebuild, get rebuild status.
- *
- * In Linux the driver supports pass through mode as if the device was
- * just another IDE controller. If the smart mode is running then
- * volumes are managed by the controller firmware and each IDE "disk"
- * is a raid volume. Even more cute - the controller can do automated
- * hotplug and rebuild.
- *
- * The pass through controller itself is a little demented. It has a
- * flaw that it has a single set of PIO/MWDMA timings per channel so
- * non UDMA devices restrict each others performance. It also has a
- * single clock source per channel so mixed UDMA100/133 performance
- * isn't perfect and we have to pick a clock. Thankfully none of this
- * matters in smart mode. ATAPI DMA is not currently supported.
- *
- * It seems the smart mode is a win for RAID1/RAID10 but otherwise not.
- *
- * TODO
- * - ATAPI UDMA is ok but not MWDMA it seems
- * - RAID configuration ioctls
- * - Move to libata once it grows up

IDE subsystem has been deprecated since 2009 and the majority (if not all) of Linux distributions have switched to use libata for ATA support exclusively. The replacement driver (pata_it821x) has been available since 2006 and it supports all the hardware supported by the old it821x host driver. Remove the deprecated it821x host driver.
