This enables using effects using triggers, etc. Signed-off-by: Sven Schwermer <sven.schwermer@disruptive-technologies.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Pavel Machek <pavel@ucw.cz> 2022-05-04T07:17:31+00:00 Bjorn Andersson bjorn.andersson@linaro.org 2022-03-03T21:43:00+00:00 urn:sha1:24e2d05d1b68981f22c984c766fabc5a93c83dba The Light Pulse Generator (LPG) is a PWM-block found in a wide range of PMICs from Qualcomm. These PMICs typically comes with 1-8 LPG instances, with their output being routed to various other components, such as current sinks or GPIOs. Each LPG instance can operate on fixed parameters or based on a shared lookup-table, altering the duty cycle over time. This provides the means for hardware assisted transitions of LED brightness. A typical use case for the fixed parameter mode is to drive a PWM backlight control signal, the driver therefor allows each LPG instance to be exposed to the kernel either through the LED framework or the PWM framework. A typical use case for the LED configuration is to drive RGB LEDs in smartphones etc, for which the driver supports multiple channels to be ganged up to a MULTICOLOR LED. In this configuration the pattern generators will be synchronized, to allow for multi-color patterns. The idea of modelling this as a LED driver ontop of a PWM driver was considered, but setting the properties related to patterns does not fit in the PWM API. Similarly the idea of just duplicating the lower bits in a PWM and LED driver separately was considered, but this would not allow the PWM channels and LEDs to be configured on a per-board basis. The driver implements the more complex LED interface, and provides a PWM interface on the side of that, in the same driver.
