cs5520: add enablebits checking

2008-08-20T18:05:10+00:00

upstream commit is 24307ffabd5b39bad443641f54b12ee2ba7a38ac

Based on sparse comments in OpenFirmware code
(no Cx5510/Cx5520 datasheet here).

This fixes 2.6.26 regression reported by TAKADA
and caused by addition of warm-plug support.

ide: it821x in pass-through mode segfaults in 2.6.26-stable

2008-08-20T18:05:09+00:00

commit 84e0f3f6c1e26588fdcb9f1b0f99d0275229bc99 upstream

The driver of ITE8212 in pass-through mode (it8212.noraid=1 on cmndline)
attempts to use the field `.dma_host_set' of the struct ide_dma_ops in
`ide_config_drive_speed' which is set to NULL by default.

So give a value to all fields of the struct ide_dma_ops.

ide: add __ide_default_irq() inline helper

2008-07-08T17:27:22+00:00

Add __ide_default_irq() inline helper and use it instead of
ide_default_irq() in ide-probe.c and ns87415.c (all host drivers
except IDE PCI ones always setup hwif->irq so it is enough to
check only for I/O bases 0x1f0 and 0x170).

This fixes post-2.6.25 regression since ide_default_irq()
define could shadow ide_default_irq() inline.

opti621: add PIO 4 support

2008-06-15T19:00:22+00:00

* Add PIO 4 support.

While at it:

* Use a single struct ide_port_info instance for OPTi621 and OPTi621X.

opti621: use pre-calculated PIO timings

2008-06-15T19:00:22+00:00

* Use pre-calculated PIO timings in ->set_pio_mode.

* Remove no longer needed compute_clocks(), cmpt_clk(), struct pio_clocks_s,
  PIO_* defines and OPTI621_DEBUG define.

There should be no functional changes caused by this patch.

opti621: program devices timings separately in ->set_pio_mode

2008-06-15T19:00:22+00:00

* Set drive->drive_data to 'pio + XFER_PIO_0' instead of 'pio',
  then simplify selecting maximum adress setup timing.

* Remove no longer needed compute_pios() and opti621_port_init_devs().

* Program devices timings separately in ->set_pio_mode.

opti621: use PCI clock value provided by controller

2008-06-15T19:00:22+00:00

Use PCI clock value provided by controller instead of depending on
a default (or user supplied) value.
