Message-id: <1444209048-29415-1-git-send-email-j.anaszewski@samsung.com> Date: Wed, 07 Oct 2015 11:10:38 +0200 From: Jacek Anaszewski <j.anaszewski@...sung.com> To: linux-leds@...r.kernel.org Cc: linux-kernel@...r.kernel.org, pavel@....cz, sakari.ailus@...ux.intel.com, andrew@...n.ch, Jacek Anaszewski <j.anaszewski@...sung.com> Subject: [PATCH v3 00/10] LED core improvements This is a third version of the patch set preparing the ground for removing work queues from LED class drivers. It is based on RFC [1]. Andrew, Pavel, Sakari - thanks for a review. ================ Changes from v2: ================ - added led_set_brightness_nopm() to be used from pm ops, and modified led_set_brightness_nosleep() to call the former - removed patch that renames EXPORT_SYMBOL to EXPORT_SYMBOL_GPL in the led-core.c - it is postponed until clear consensus is reached on it - added acks from Pavel Machek - removed from the set a patch that has been applied: [PATCH 1/5] leds: core: Move LED core callbacks out of led-class.c ================ Changes from v1: ================ - removed useless use of else in led_set_brightness() - switched to removing error code instead of emitting warning from led_set_brightness_sync() in case software blink fallback is enabled - moved __led_set_brightness() contents to set_brightness_delayed() - removed description of internal led_set_brightness_nosleep() from led-class.txt documentation, and modified description of led_set_brightness() and led_set_brightness_sync() - renamed LED_BLINK_CHANGE flag to more meaningful LED_BLINK_BRIGHTNESS_CHANGE - Fixed stylistic issues in a few comments - Adopted old brightness_set_sync() op description to a new brightness_set_blocking() op - Fixed led_set_brightness_nosleep to avoid scheduling spurious set_brightness_work - made LED core using EXPORT_SYMBOL_GPL consistently - switched v4l2-flash-led-class wrapper to using led_set_brightness_sync API for setting torch brightness - merged with patch set "LED flash: Set brightness in a sync way on demand" ====================== Original cover letter: ====================== This patch set prepares the ground for removing work queues from LED class drivers, and is a follow up of the patch set [1]. LED core modifications have been reorganized to make them more clear and easier to review. The patch set is reduced in comparison to it its predecessor, to expose the modifications indispensable for the LED core to gain the capability of handling brightness_set_blocking ops, that is without work queues.
