* libata: implement and use ata_port_desc() to report port configurationTejun Heo2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, port configuration reporting has the following problems. * iomapped address is reported instead of raw address * report contains irrelevant fields or lacks necessary fields for non-SFF controllers. * host->irq/irq2 are there just for reporting and hacky. This patch implements and uses ata_port_desc() and ata_port_pbar_desc(). ata_port_desc() is almost identical to ata_ehi_push_desc() except that it takes @ap instead of @ehi, has no locking requirement, can only be used during host initialization and " " is used as separator instead of ", ". ata_port_pbar_desc() is a helper to ease reporting of a PCI BAR or an offsetted address into it. LLD pushes whatever description it wants using the above two functions. The accumulated description is printed on host registration after "[S/P]ATA max MAX_XFERMODE ". SFF init helpers and ata_host_activate() automatically add descriptions for addresses and irq respectively, so only LLDs which isn't standard SFF need to add custom descriptions. In many cases, such controllers need to report different things anyway. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [libata] Remove ->port_disable() hookJeff Garzik2007-10-12
| | | | | | | | It was always set to ata_port_disable(). Removed the hook, and replaced the very few ap->ops->port_disable() callsites with direct calls to ata_port_disable(). Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [libata] Remove ->irq_ack() hook, and ata_dummy_irq_on()Jeff Garzik2007-10-12
| | | | | | | | | | | | | * ->irq_ack() is redundant to what the irq handler already performs... chk-status + irq-clear. Furthermore, it is only called in one place, when screaming-irq-debugging is enabled, so we don't want to bother with a hook just for that. * ata_dummy_irq_on() is only ever used in drivers that have no callpath reaching ->irq_on(). Remove .irq_on hook from those drivers, and the now-unused ata_dummy_irq_on() Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [ARM] pata_icside: fix the FIXMEsRussell King2007-08-06
| | | | | | | | | | | | Alan Cox suggested that the solution to the FIXMEs in pata_icside is to use a private postreset method to detect the lack of devices on a port, and in such a case, disable the interrupt for the port. This patch implements such a method, and removes the hard coded disable of port 0. Tested as working. Acked-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [libata] PATA drivers: remove ATA_FLAG_SRSTJeff Garzik2007-07-09
| | | | | | | This flag only has meaning in old-EH drivers, and these drivers have already been converted to the new EH. Remove. Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [ARM] pata_icside: fix build errorsRussell King2007-05-11
| | | | | | | Building on the previous two ecard infrastructure changes, this patch fixes the pata_icside build errors caused by the recent libata changes. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] ecard: add ecardm_iomap() / ecardm_iounmap()Russell King2007-05-11
| | | | | | | Add devres ecardm_iomap() and ecardm_iounmap() for Acorn expansion cards. Convert all expansion card drivers to use them. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] ecard: add helper function for setting ecard irq opsRussell King2007-05-11
| | | | | | | | | | | | | | | Rather than having every driver fiddle about setting its private IRQ operations and data, provide a helper function to contain this functionality in one place. Arrange to remove the driver-private IRQ operations and data when the device is removed from the driver, and remove the driver private code to do this. This fixes potential problems caused by drivers forgetting to remove these hooks. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
