From 66e9feb03e7cf8983b1d0c540e2dad90d5146d48 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 9 Nov 2025 16:53:39 +0100 Subject: [PATCH] spi: Add TODO comment about ACPI GPIO setup Add a TODO comment that ideally the ACPI/gpiolib core code should take care of setting GPIO direction and/or bias according to ACPI GPIO resources. If this TODO gets implemented then the acpi_dev_gpio_irq_get() call in acpi_register_spi_device() can be dropped.
