From 3a6c501e96eefb7fd83fbaf9ac29956036d02896 Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Tue, 5 Feb 2019 17:33:35 +0000 Subject: dt-bindings: spi: atmel-quadspi: QuadSPI driver for Microchip SAM9X60 The sam9x60 qspi controller uses 2 clocks, one for the peripheral register access, the other for the qspi core and phy. Both are mandatory.
