2016-06-28drivers: ata: pata_arasan_cf: use the same name for the same lockIago Abal
Note that `&acdev->host->lock' and `qc->ap->lock' denote the same lock, and it's particularly confusing to spin_lock on the former but spin_unlock on the latter. Signed-off-by: Iago Abal <mail@iagoabal.eu> Signed-off-by: Tejun Heo <tj@kernel.org>

A couple device specific minor updates and a kernel doc change" * 'for-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: ata: pata_arasam_cf: Use devm_clk_get libata: fix libata-core.c kernel-doc warning ata: sata_rcar: Remove obsolete sata-r8a779* platform_device_id entries
2015-08-22ata: pata_arasam_cf: Use devm_clk_getVaishali Thakkar
This patch introduces the use of managed resource function devm_clk_get instead of clk_get and removes corresponding call to clk_put in the remove function. To be compatible with the change various gotos are replaced with direct returns, and unneeded label is dropped.

2013-05-24ata: use platform_{get,set}_drvdata()Jingoo Han
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.

2013-04-19ata: arasan: remove the need for platform_dataArnd Bergmann
This adds a complete DT binding for the arasan device driver. There is currently only one user, which is the spear13xx platform, so we don't actually have to parse all the properties until another user comes in, but this does use the generic DMA binding to find the DMA channel. The patch is untested so far and is part of a series to convert the spear platform over to use the generic DMA binding, so it should stay with the rest of the series.

2013-01-03Drivers: ata: remove __dev* attributes.Greg Kroah-Hartman
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.

'acdev->qc', 'acdev->qc->ap', and 'acdev->qc->tf' expressions are used multiple times in this function, so it makes sense to use the local variables for them.

This will fix warnings like following when CONFIG_PM_SLEEP is not set: warning: 'xxx_suspend' defined but not used [-Wunused-function] warning: 'xxx_resume' defined but not used [-Wunused-function] Because SET_SYSTEM_SLEEP_PM_OPS(suspend_fn, resume_fn) Only references the callbacks on CONFIG_PM_SLEEP (instead of CONFIG_PM).

2012-09-13pata_arasan: Add clk_{un}prepare() supportViresh Kumar

2011-03-14ata/pata_arasan_cf: fill dma chan->private from pdata->dma_privViresh Kumar
Some DMA controllers (eg: drivers/dma/dw_dmac*) allow platform specific configuration for dma transfers. User drivers need to set chan->private field of channel with pointer to configuration data. This patch takes dma_priv data from platform data and passes it to chan->private_data, in order to pass platform specific configuration to DMAC controller.
