From 2644f912b41012c1ce5ff9be99efeec721491b86 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 10 Feb 2020 11:15:46 +0100 Subject: backlight: pwm_bl: Switch to full GPIO descriptor The PWM backlight still supports passing a enable GPIO line as platform data using the legacy API. It turns out that ever board using this mechanism except one is pass .enable_gpio = -1. So we drop all these cargo-culted -1's from all instances of this platform data in the kernel. The remaning board, Palm TC, is converted to pass a machine descriptior table with the "enable" GPIO instead, and delete the platform data entry for enable_gpio and the code handling it and things should work smoothly with the new API.
