Subject: [PATCH 1/5] spi: sirf: correct TXFIFO empty interrupt status bit
Date: Mon, 14 Apr 2014 14:29:57 +0800	[thread overview]
Message-ID: <1397457001-5266-2-git-send-email-21cnbao@gmail.com> (raw)
In-Reply-To: <1397457001-5266-1-git-send-email-21cnbao-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

From: Qipan Li <Qipan.Li-kQvG35nSl+M@public.gmane.org>

the old code uses wrong marco - SIRFSOC_SPI_FIFO_FULL is not for
FIFO interrupt status, it is for FIFO status. here in the ISR,
SIRFSOC_SPI_TXFIFO_EMPTY is the right bit for SPI TXFIFO interrupt
status.
