From 40fc56ee608cdb20022c225ac6f1e4b7ba63f8f1 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Mon, 19 Dec 2022 11:20:15 -0800 Subject: [PATCH] gpiolib: of: remove of_get_gpio[_flags]() and of_get_named_gpio_flags() There are no more users of these APIs in the mainline kernel, remove them. This leaves of_get_named_gpio() as the only legacy OF-specific API.
