f14aa5ea - leds: rgb: leds-ktd202x: Get device properties through fwnode to support ACPI

Fri, 31 May 2024 11:41:19 +0000

leds: rgb: leds-ktd202x: Get device properties through fwnode to support ACPIThis LED controller is installed on a Xiaomi pad2 and it is an x86platform. The original driver is based on the device tree and can't beused for this ACPI based system. This patch migrated the driver to usefwnode to access the properties. Moreover, the fwnode API supports thedevice tree so this work won't affect the original implementations.Signed-off-by: Kate Hsuan Tested-by: André Apitzsch # on BQ Aquaris M5Reviewed-by: Hans de Goede Reviewed-by: Andy Shevchenko Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20240531114124.45346-2-hdegoede@redhat.comSigned-off-by: Lee Jones List of files: /linux-6.15/drivers/leds/rgb/Kconfig

leds: rgb: Drop obsolete dependency on COMPILE_TESTSince commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), itis possible to test-build any driver which depends on OF on anyarchitecture by explicitly selecting OF.

Fri, 28 Jul 2023 15:37:31 +0000

leds: rgb: Add a multicolor LED driver to group monochromatic LEDsGrouping multiple monochrome LEDs into a multicolor LED device has a fewbenefits over handling the group in user-space:- The state of the LEDs relative to each other is consistent. In other words, if 2 threads competes to set the LED to green and red, the end-result cannot be black or yellow.- The multicolor LED as a whole can be driven through the sysfs LED interface.Signed-off-by: Jean-Jacques Hiblot Reviewed-by: Lee Jones Link: https://lore.kernel.org/r/20230728153731.3742339-5-jjhiblot@traphandler.comSigned-off-by: Lee Jones List of files: /linux-6.15/drivers/leds/rgb/Kconfig

leds: rgb: mt6370: Correct config name to select in LEDS_MT6370_RGBCommit 55a8a5c16eb3 ("leds: rgb: mt6370: Add MediaTek MT6370 current sinktype LED Indicator support") introduces the config LEDS_MT6370_RGB, whichselects the non-existing config LINEAR_RANGE. As the driver includeslinux/linear_range.h, it is a safe guess that the config actually intendsto select LINEAR_RANGES, which provides the library implementation for thefunction prototypes defined in the linear_range header file.Correct this naming confusion in the LEDS_MT6370_RGB config definition.Fixes: 55a8a5c16eb3 ("leds: rgb: mt6370: Add MediaTek MT6370 current sink type LED Indicator support")Signed-off-by: Lukas Bulwahn Acked-by: Pavel Machek Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20230323105410.10396-1-lukas.bulwahn@gmail.com List of files: /linux-6.15/drivers/leds/rgb/Kconfig

24e2d05d - leds: Add driver for Qualcomm LPG

Thu, 03 Mar 2022 21:43:00 +0000

leds: Add driver for Qualcomm LPGThe Light Pulse Generator (LPG) is a PWM-block found in a wide range ofPMICs from Qualcomm. These PMICs typically comes with 1-8 LPG instances,with their output being routed to various other components, such ascurrent sinks or GPIOs.Each LPG instance can operate on fixed parameters or based on a sharedlookup-table, altering the duty cycle over time. This provides the meansfor hardware assisted transitions of LED brightness.A typical use case for the fixed parameter mode is to drive a PWMbacklight control signal, the driver therefor allows each LPG instanceto be exposed to the kernel either through the LED framework or the PWMframework.A typical use case for the LED configuration is to drive RGB LEDs insmartphones etc, for which the driver supports multiple channels to beganged up to a MULTICOLOR LED. In this configuration the patterngenerators will be synchronized, to allow for multi-color patterns.The idea of modelling this as a LED driver ontop of a PWM driver wasconsidered, but setting the properties related to patterns does not fitin the PWM API. Similarly the idea of just duplicating the lower bits ina PWM and LED driver separately was considered, but this would not allowthe PWM channels and LEDs to be configured on a per-board basis. Thedriver implements the more complex LED interface, and provides a PWMinterface on the side of that, in the same driver.Signed-off-by: Bjorn Andersson Tested-by: Douglas Anderson Tested-by: Luca Weiss Reviewed-by: Marijn Suijten Tested-by: Marijn Suijten [On the Sony Xperia Nile Discovery, SDM630]Signed-off-by: Pavel Machek List of files: /linux-6.15/drivers/leds/rgb/Kconfig
