From ef396df99251b848596c717b63ff4fe74a941193 Mon Sep 17 00:00:00 2001 From: Claudiu Beznea Date: Wed, 22 Jul 2020 10:38:25 +0300 Subject: clk: at91: clk-utmi: add utmi support for sama7g5 Add UTMI support for SAMA7G5. SAMA7G5's UTMI control is done via XTALF register. Values written at bits 2..0 in this register correspond to the on board crystal oscillator frequency.
