From 41ad9232f2e68e0c86ffebb91efb4d8c071502b6 Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Wed, 28 Feb 2018 15:56:41 +0100 Subject: [PATCH 1/3] MAINTAINERS: ARM: at91: update entry for ARM/Microchip Change the entry name and move it to its alphabetical location. We move to ARM/Microchip instead of ARM/ATMEL to reflect the merger that is now nearly 2 years old. AT91 is kept as the identity of our community. The atmel pattern is obviously kept as well. I removed the names of the different SoCs as they are better exposed in the arch/arm/mach-at91/Kconfig entries.
