Tejun Heo 3af9a77af9 libata-pmp: implement Port Multiplier support ... Implement Port Multiplier support. To support PMP, a LLDD has to supply ops->pmp_read() and pmp_write(). If non-null, ->pmp_attach and ->pmp_detach are called on PMP attach and detach, respectively. ->pmp_read/write() can be called while the port is frozen, so they must be implemented by polling. This patch supplies several helpers to ease ->pmp_read/write() implementation. Also, irq_handler and error_handler must be PMP aware. Most of PMP aware EH can be done by calling ata_pmp_do_eh() with appropriate methods. PMP EH uses separate set of reset methods and this patch implements standard prereset, hardreset and postreset methods. This patch only implements PMP support. The next patch will integrate PMP into the reset of libata and thus enable PMP support.
