From 04133bb1e710bc3d5532694999fbb3d0f1421724 Mon Sep 17 00:00:00 2001 From: Alexandre Torgue Date: Wed, 2 Feb 2022 15:00:04 +0100 Subject: [PATCH] irqchip/stm32-exti: Add STM32MP13 support Enhance stm32-exti driver to support STM32MP13 SoC. This SoC uses the same hardware version than STM32MP15. Only EXTI line mapping is changed and following EXTI lines are supported: GPIO, RTC, I2C[1-5], UxART[1-8], USBH_EHCI, USBH_OHCI, USB_OTG, LPTIM[1-5], ETH[1-2].
