Subject: [PATCH] mtd: rawnand: stm32_fmc2: increase DMA completion timeouts
Date: Fri, 21 Jun 2019 16:48:00 +0200 [thread overview]
Message-ID: <1561128480-14531-1-git-send-email-christophe.kerello@st.com> (raw)
When the system is overloaded, DMA data transfer completion occurs after
100ms. Increase the timeouts to let it the time to complete.
