From 561eca4990557b684605090fe6a2f50cecec34e1 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 18 Aug 2016 14:57:47 +0200 Subject: MIPS: TXx9: tx39xx: Move GPIO setup from .mem_setup() to .arch_init() txx9_gpio_init() calls gpiochip_add_data(), which fails with -ENOMEM as it is called too early in the boot process. This causes all subsequent GPIO operations to fail silently. Postpone all GPIO setup to .arch_init() time to fix this.
