ata: Drop commas after OF match table sentinels

2022-03-07T02:49:10Z

It does not make sense to have a comma after a sentinel, as any new elements must be added before the sentinel. Add comments to clarify the purpose of the empty elements. Rewrap entries to a single line to have a consistent style.

ata: ahci_platform: enable to get and control reset

2018-08-22T15:08:28Z

Unlike SoC-specific driver, generic ahci_platform driver doesn't have any chances to control resets. This adds AHCI_PLATFORM_GET_RESETS to ahci_platform_get_resources() on the generic driver to enable reset control support.

ata: add an extra argument to ahci_platform_get_resources()

2018-08-22T15:08:27Z

Add an extra argument to ahci_platform_get_resources(), that is for the bitmap representing the resource to get in this function. Currently there is no resources to be defined, so all the callers set '0' to the argument.

The Exynos5440 is not actively developed, there are no development boards available and probably there are no real products with it. Remove wide-tree support for Exynos5440. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Rob Herring

ata: ahci_platform: allow disabling of hotplug to save power

2018-06-18T17:58:55Z

A number of resources remain powered to support hotplug. On platforms I've worked with, allowing the ahci_platform to suspend saves about 150mW. This patch enables rpm and allows the device to be auto-suspended through sysfs. Signed-off-by: Samuel Morris Signed-off-by: Tejun Heo

ata: ahci_platform: Add shutdown handler

2017-08-04T20:34:14Z

The newly introduced ahci_platform_shutdown() method is called during system shutdown to disable host controller DMA and interrupts in order to avoid potentially corrupting or otherwise interfering with a new kernel being started with kexec. Signed-off-by: Nate Watterson Signed-off-by: Tejun Heo
