From 6af78d03d394cb0b28716aaaf684ab99bdeb758d Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Fri, 2 Oct 2020 14:08:54 +0200 Subject: [PATCH] arm: stm32: cleanup arch gpio.h Cosmetic update of gpio.h: - remove enumerate: stm32_gpio_port, stm32_gpio_pin because STM32_GPIO_XXX values are unused - move STM32_GPIOS_PER_BANK in stm32_gpio.c as its value is IP dependent and not arch dependent No functional change as number of banks and number of gpio by banks is managed by device tree since since DM migration and commit 8f651ca60ba1 ("pinctrl: stm32: Add get_pins_count() ops").
