From f0b6d3cc29b709089f7a0de6a3d64a73ed0d67bd Mon Sep 17 00:00:00 2001 From: Tomer Tayar Date: Tue, 6 Sep 2022 16:37:14 +0300 Subject: habanalabs/gaudi2: increase hard-reset sleep time to 2 sec The access to the device registers is blocked during hard reset, until preboot runs and allows the access to specific registers, including the PSOC BTM_FSM register which is used to know when the reset is done. Between the reset request and until this register is polled there is a small delay of 500 msec which is not enough for F/W to process the reset and for preboot to run, so the register might be accessed while it is blocked. To avoid it, increase the delay to 2 sec.
