From bc5c75e0a5a9400f81a987cc720100ac475fa4d8 Mon Sep 17 00:00:00 2001 From: Knox Chiou Date: Wed, 23 Feb 2022 22:35:00 +0000 Subject: [PATCH] nvmem: qfprom: Increase fuse blow timeout to prevent write fail sc7180 blow fuses got slightly chances to hit qfprom_reg_write timeout. Current timeout is simply too low. Since blowing fuses is a very rare operation, so the risk associated with overestimating this number is low. Increase fuse blow timeout from 1ms to 10ms.
