From 952de38ef4fbb466c8f31b7d55516ba23955975a Mon Sep 17 00:00:00 2001 From: Sungbo Eo Date: Sun, 20 Feb 2022 00:19:31 +0900 Subject: [PATCH] Revert "ramips: increase spi-max-frequency for ipTIME mt7620 devices" This reverts commit 13a185bf8acb67da4a68873e560876c0e60b1a87. There was a report that one A1004ns device fails to detect its flash chip correctly: [ 1.470297] spi-nor spi0.0: unrecognized JEDEC id bytes: e0 10 0c 40 10 08 [ 1.484110] spi-nor: probe of spi0.0 failed with error -2 It also uses a different flash chip model: * in my hand: Winbond W25Q128FVSIG (SOIC-8) * reported: Macronix MX25L12845EMI-10G (SOP-16) Reducing spi-max-frequency solved the detection failure. Hence revert.
