Please read the summary (changes from version 2): - added patch 1, which drops unnecessary mutex locking - added patch 2, which changes SMBUS calls to regular I2C transfers - added patch 3, changing sprintf() to dedicated sysfs_emit() - patch 4 replaces patch 1 from v2, which changed max_brightness to 1. Instead, we make set_brightness() more effective by avoiding unnecessary I2C transactions (for example if brightness is being changed between 0 and 255, we do not send the color changing I2C command, only the enabling/disabling command) - patch 5 is updated patch 3 from v2, which adds support for enabling HW blinking mode on the LEDs - patch 6 adds support for enabling/disabling HW gamma correction of the RGB LEDs. Gamma correction is supported by newer MCU firmware versions Marek Marek Behún (6): leds: turris-omnia: drop unnecessary mutex locking leds: turris-omnia: do not use SMBUS calls leds: turris-omnia: use sysfs_emit() instead of sprintf() leds: turris-omnia: make set_brightness() more efficient leds: turris-omnia: support HW controlled mode via private trigger leds: turris-omnia: add support for enabling/disabling HW gamma correction .../sysfs-class-led-driver-turris-omnia | 14 + drivers/leds/Kconfig | 1 + drivers/leds/leds-turris-omnia.c | 363 +++++++++++++++--- 3 files changed, 329 insertions(+), 49 deletions(-)
