From a0b83af0dfd751f88bf5c452e7bbe7efe877da3d Mon Sep 17 00:00:00 2001 From: Vignesh R Date: Mon, 1 Aug 2016 18:36:55 +0530 Subject: [PATCH] ARM: dts: dra7xx: Increase spi-max-frequency to 76.8MHz for QSPI According to AM572x DM SPRS953A, QSPI maximum bus speed can be 76.8MHz. Therefore, increase the spi-max-frequency value of QSPI node to 76.8MHz for DRA74 and DRA72 evm. This improves flash raw read speed by ~2MB/s.
