pata_octeon_cf: use of_property_read_{bool|u32}()

2017-08-28T17:44:24+00:00

The Octeon CF driver basically  open-codes of_property_read_{bool|u32}()
using  of_{find|get}_property() calls in its  probe() method.  Using the
modern DT APIs saves 2 LoCs and 16 bytes of object code (MIPS gcc 3.4.3).

ata: pata_octeon_cf: make of_device_ids const.

2017-06-19T18:03:04+00:00

of_device_ids are not supposed to change at runtime. All functions
working with of_device_ids provided by  work with const
of_device_ids. So mark the non-const structs as const.

pata_octeon_cf: remove unused local variables from octeon_cf_set_piomode()

@t1 and @t2i are calculated along with @t2 but never used.  Drop them.

ata: pass queued command to ->sff_data_xfer method

2017-01-10T16:11:17+00:00

For Atari Falcon PATA support we need to check the current command
in its ->sff_data_xfer method.  Update core code and all users
accordingly.

There should be no functional changes caused by this patch.

pata_octeon_cf: fix broken build

2015-06-08T09:03:04+00:00

MODULE_DEVICE_TABLE is referring to wrong driver's table and breaks the
build. Fix that.

ata: drop owner assignment from platform_drivers

2014-10-20T14:20:17+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

pata_octeon_cf: use devm_kzalloc() to allocate cf_port

2014-04-14T17:33:28+00:00

As a nice side effect this fixes the cf_port leak on
dma_coerce_mask_and_coherent() or ata_host_activate()
failure.

DMA-API: ata: pata_octeon_cf: convert to use dma_coerce_mask_and_coherent()

2013-10-31T14:48:49+00:00

Convert this code sequence:
	pdev->dev.coherent_dma_mask = DMA_BIT_MASK(64);
	pdev->dev.dma_mask = &pdev->dev.coherent_dma_mask;
to use dma_coerce_mask_and_coherent() to avoid bypassing the architecture
check on the DMA mask.

ata: use dev_get_platdata()

2013-07-30T12:59:24+00:00

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.
