From d03f23df6ff47898d76f06b3aa5dadcfa1ec8f4f Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Sun, 19 Feb 2017 23:40:22 +0100 Subject: [PATCH 1/3] spi/bcm63xx-hsspi: allow providing clock rate through a second clock Instead of requiring the hsspi clock to have a rate, allow using a second clock for providing the Hz rate, which is probably more correct anyway.
