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.
