ata: remove bf54x driver

2018-03-26T13:56:56+00:00

The blackfin architecture is getting removed, so this driver is obsolete as well. Acked-by: Tejun Heo Signed-off-by: Arnd Bergmann

ata: bf54x: cut drvdata assignment

2017-05-30T15:54:36+00:00

ata_host_alloc_pinfo() assigns the host pointer to the struct device * drvdata, do not assign it a second time. Signed-off-by: Linus Walleij Signed-off-by: Tejun Heo

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. Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Tejun Heo

gpio: Include linux/gpio.h instead of asm/gpio.h

2016-02-15T23:20:03+00:00

Most arches have an asm/gpio.h that merely includes linux/gpio.h. The others select ARCH_HAVE_CUSTOM_GPIO_H, and when that's selected, linux/gpio.h includes asm/gpio.h. Therefore, code should include linux/gpio.h instead of including asm/gpio.h directly. Remove includes of asm/gpio.h, adding an include of linux/gpio.h when necessary. This is a follow-on to 7563bbf89d06 ("gpiolib/arches: Centralise bolierplate asm/gpio.h").

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. Signed-off-by: Wolfram Sang

ata: use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable in host drivers

2014-05-10T02:37:49+00:00

This patch fixes host drivers to use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable. Benefits of this change: * unused code is not being compiled in for CONFIG_PM=y, CONFIG_PM_SLEEP=n and CONFIG_PM_RUNTIME=y configurations * easier transition to use struct dev_pm_ops and SIMPLE_DEV_PM_OPS() in the future * more consistent code (there are host drivers which are using the correct CONFIG_PM_SLEEP checks already) The patch leaves the core libata code and ->port_[suspend,resume] support in sata_[inic162x,nv,sil24].c alone for now.

ata: use platform_{get,set}_drvdata()

2013-05-24T01:26:13+00:00

Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device. Also, unnecessary dev_set_drvdata() is removed, because the driver core clears the driver data to NULL after device_release or on probe failure. Signed-off-by: Jingoo Han Signed-off-by: Tejun Heo

Drivers: ata: remove __dev* attributes.

2013-01-03T23:57:03+00:00

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

[libata] pata_bf54x: Support sg list in bmdma transfer.

2012-01-18T01:49:28+00:00

BF54x on-chip ATAPI controller allows maximum 0x1fffe bytes to be transfered in one ATAPI transfer. So, set the max sg_tablesize to 4. Signed-off-by: Sonic Zhang Signed-off-by: Jeff Garzik

pata_bf54x: fix BMIDE status register emulation

2012-01-09T00:24:02+00:00

The author of this driver clearly wasn't familiar with the BMIDE specification (also known as SFF-8038i) when he implemented the bmdma_status() method: first, the interrupt bit of the BMIDE status register corresponds to nothing else but INTRQ signal (ATAPI_DEV_INT here); second, the error bit is only set if the controller encounters issue doing the bus master transfers, not on the IDE DMA burst termination interrupts like here (moreover, setting the error bit doesn't cause an interrupt). We now need to disable all those unused interrupts... (The only thing I couldn't figure out is how to flush the FIFO to memory once the interrupt happens as required by the mentioned spec.)
