Subject: [PATCH v2 2/2] mtd: nand: raw: brcmnand: When oops in progress use pio and interrupt polling
Date: Thu, 16 May 2019 11:45:40 -0400	[thread overview]
Message-ID: <1558022399-24863-2-git-send-email-kdasu.kdev@gmail.com> (raw)
In-Reply-To: <1558022399-24863-1-git-send-email-kdasu.kdev@gmail.com>

If mtd_oops is in progress switch to polling for nand command completion
interrupts and use PIO mode wihtout DMA so that the mtd_oops buffer can
be completely written in the assinged nand partition.
