From adfdfcbdbd32b356323a3db6d3a683270051a7e6 Mon Sep 17 00:00:00 2001 From: Jerome Neanne Date: Thu, 29 Sep 2022 15:25:25 +0200 Subject: regulator: gpio: Add input_supply support in gpio_regulator_config This is simillar as fixed-regulator. Used to extract regulator parent from the device tree. Without that property used, the parent regulator can be shut down (if not an always on). Thus leading to inappropriate behavior: On am62-SP-SK this fix is required to avoid tps65219 ldo1 (SDMMC rail) to be shut down after boot completion.
