The libata core is now a trigger source just +like before the IDE disk driver. It's merely a replacement of the +string ide by disk. + +The patch is taken from http://dev.gentoo.org/~josejx/ata.patch and is +widely used by any ibook/powerbook owners with great satisfaction. +Likewise, it is very often used successfully on different ARM platforms. + +Unlike the original patch, the existing 'ide-disk' trigger is still +available for backward compatibility. That reduce the amount of patches +in affected device trees out of the mainline kernel. For further +development, the new name 'disk-activity' should be used. + +Cc: Joseph Jezak <josejx@gentoo.org> +Cc: Jörg Sommer <joerg@alea.gnuu.de> +Cc: Richard Purdie <rpurdie@rpsys.net> +Signed-off-by: Stephan Linz <linz@li-pro.net> +Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com> +--- + drivers/ata/libata-core.c | 4 ++++ + drivers/ide/ide-disk.c | 2 +- + drivers/leds/trigger/Kconfig | 8 +++---- + drivers/leds/trigger/Makefile | 2 +- + drivers/leds/trigger/ledtrig-disk.c | 41 +++++++++++++++++++++++++++++++++ + drivers/leds/trigger/ledtrig-ide-disk.c | 36 ----------------------------- + include/linux/leds.h | 6 ++--- + 8 files changed, 55 insertions(+), 46 deletions(-) + create mode 100644 drivers/leds/trigger/ledtrig-disk.c + delete mode 100644 drivers/leds/trigger/ledtrig-ide-disk.c + +diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c +index 6be7770..2eca572 100644 +--- a/drivers/ata/libata-core.c ++++ b/drivers/ata/libata-core.c +@@ -69,6 +69,7 @@ + #include <asm/unaligned.h> + #include <linux/cdrom.h> + #include <linux/ratelimit.h> ++#include <linux/leds.h> + #include <linux/pm_runtime.h> + #include <linux/platform_device.h> + +@@ -5072,6 +5073,9 @@ void ata_qc_complete(struct ata_queued_cmd *qc) + { + struct ata_port *ap = qc->ap; + ++ /* Trigger the LED (if available) */ ++ ledtrig_disk_activity(); ++ + /* XXX: New EH and old EH use different mechanisms to + * synchronize EH with regular execution path. + * +diff --git a/drivers/ide/ide-disk.c b/drivers/ide/ide-disk.c +index 05dbcce..5ceb176 100644 +--- a/drivers/ide/ide-disk.c ++++ b/drivers/ide/ide-disk.c +@@ -186,7 +186,7 @@ static ide_startstop_t ide_do_rw_disk(ide_drive_t *drive, struct request *rq, + BUG_ON(drive->dev_flags & IDE_DFLAG_BLOCKED); + BUG_ON(rq->cmd_type != REQ_TYPE_FS); + +- ledtrig_ide_activity(); ++ ledtrig_disk_activity(); + + pr_debug("%s: %sing: block=%llu, sectors=%u\n", + drive->name, rq_data_dir(rq) == READ ?
