From 1bed576d4144236f280427420296c3590d360729 Mon Sep 17 00:00:00 2001 From: Asherah Connor <ashe@kivikakk.ee> Date: Wed, 3 Mar 2021 14:46:47 +1100 Subject: [PATCH] video: SIMPLE_PANEL depends on DM_GPIO SIMPLE_PANEL currently only depends on PANEL && BACKLIGHT, but the code makes references to dm_gpio_set_value and gpio_request_by_name. These are defined in drivers/gpio/gpio-uclass.c, so a dependency on DM_GPIO corrects these link errors: aarch64-linux-gnu-ld.bfd: drivers/built-in.o: in function `simple_panel_set_backlight': /home/kameliya/u-boot/drivers/video/simple_panel.c:42: undefined reference to `dm_gpio_set_value' aarch64-linux-gnu-ld.bfd: drivers/built-in.o: in function `simple_panel_enable_backlight': /home/kameliya/u-boot/drivers/video/simple_panel.c:27: undefined reference to `dm_gpio_set_value' aarch64-linux-gnu-ld.bfd: drivers/built-in.o: in function `simple_panel_of_to_plat': /home/kameliya/u-boot/drivers/video/simple_panel.c:72: undefined reference to `gpio_request_by_name' This issue is only exposed if you have a board which enables CONFIG_DM_VIDEO without CONFIG_DM_GPIO; so far, none do, but soon a QEMU board may.
