[PATCH v7 0/5] Add a generic driver for LED-based backlight
by Jean-Jacques Hiblot 14 Oct '19

14 Oct '19

This series aims to add a led-backlight driver, similar to pwm-backlight, but using a LED class device underneath. A few years ago (2015), Tomi Valkeinen posted a series implementing a backlight driver on top of a LED device: https://patchwork.kernel.org/patch/7293991/ https://patchwork.kernel.org/patch/7294001/ https://patchwork.kernel.org/patch/7293981/ The discussion stopped because Tomi lacked the time to work on it. changes in v7: - rebased on top of linux-leds/for-next - populate the … [View More]of_node member of the LED device if fwnode is a of_node (this is a new patch and the first of the series). - devm_led_get() works only when the device tree is used. Add a few checks for that. changes in v6: - trim the list of included headers - remove useless definition of BKL_FULL_BRIGHTNESS changes in v5: - removed LED brightness scaling - disable sysfs the interface of the LEDs when used by the backlight device changes in v4: - fix dev_err() messages and commit logs following the advices of Pavel - cosmetic changes (indents, getting rid of "? 1 : 0" in led_match_led_node()) changes in v3: - dt binding: don't limit the brightness range to 0-255. Use the range of the underlying LEDs. as a side-effect, all LEDs must now have the same range - driver: Adapt to dt binding update. - driver: rework probe() for clarity and remove the remaining goto. changes in v2: - handle more than one LED. - don't make the backlight device a child of the LED controller. - make brightness-levels and default-brightness-level optional - removed the option to use a GPIO enable. - removed the option to use a regulator. It should be handled by the LED core - don't make any change to the LED core (not needed anymore) Jean-Jacques Hiblot (3): leds: populate the device's of_node when possible leds: Add managed API to get a LED from a device driver dt-bindings: backlight: Add led-backlight binding Tomi Valkeinen (2): leds: Add of_led_get() and led_put() backlight: add led-backlight driver .../bindings/leds/backlight/led-backlight.txt | 28 ++ drivers/leds/led-class.c | 106 ++++++- drivers/video/backlight/Kconfig | 7 + drivers/video/backlight/Makefile | 1 + drivers/video/backlight/led_bl.c | 260 ++++++++++++++++++ include/linux/leds.h | 6 + 6 files changed, 407 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/leds/backlight/led-backlight.txt create mode 100644 drivers/video/backlight/led_bl.c -- 2.17.1 [View Less]

linux-next: manual merge of the drm-misc tree with the admgpu tree
by Stephen Rothwell 14 Oct '19

14 Oct '19

Hi all, Today's linux-next merge of the drm-misc tree got a conflict in: drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_mst_types.c between commit: 2f232cf29e03 ("drm/amdgpu/dm/mst: Don't create MST topology managers for eDP ports") from the admgpu tree and commit: ae85b0df124f ("drm_dp_cec: add connector info support.") from the drm-misc tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial … [View More]
