From 48bf88ebb1abf55168f636d7a6edf2ca79be13c6 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Wed, 6 May 2020 14:25:20 +0100 Subject: [PATCH] overlays: sc16is752-spi1: Add xtal parameter The other sc16is75x overlays have an xtal parameter to allow a different crystal frequency to be specified, but sc16is752-spi1 doesn't. Fix this omission.
