From d11a79dd047e18dd0b76bc9abebb8470858856d6 Mon Sep 17 00:00:00 2001 From: Luca Weiss Date: Tue, 18 Apr 2023 18:43:20 +0200 Subject: [PATCH] leds: qcom-lpg: Add support for PMI632 LPG The PMI632 PMIC contains 5 PWM channels, 3 of which can be used for LEDs. For the LED pattern it doesn't have LUT like other PMICs but uses SDAM instead. This is not currently implemented in the driver but since LPG works fine without it, add support for the PMIC now.
