Subject: next-20150511 / omap2-mcspi: regression for sdp4430 boot
Date: Mon, 11 May 2015 11:50:19 -0500 [thread overview]
Message-ID: <5550DDCB.8010303@ti.com> (raw)
Hi,
SDP4430 uses a SPI based network chip ks8851.
next-20150508:
https://github.com/nmenon/kernel-test-logs/blob/next-20150508/omap2plus_defconfig/sdp4430.txt
However, next-20150511:
https://github.com/nmenon/kernel-test-logs/blob/next-20150511/omap2plus_defconfig/sdp4430.txt
Generates infinite "ks8851 spi1.0: ks8851_irq: spi bus error" errors
and hangs the platform.
Bisected the issue down to the following two commits when reverted
allows the board to function:
commit b28cb9414db9f8e42ac18c9e360e4e99cda42489
Author: Michael Welling <mwelling@ieee.org>
Date: Thu May 7 18:36:53 2015 -0500
spi: omap2-mcspi: Switch driver to use transfer_one
Switches from transfer_one_message to transfer_one to prepare
driver for
use of GPIO chip selects.
Signed-off-by: Michael Welling <mwelling@ieee.org>
Signed-off-by: Mark Brown <broonie@kernel.org>
Reverting this alone: http://paste.ubuntu.org.cn/2594735 (did not boot up)
commit bc7f9bbc80bcc77745b3f54ec4e7103e3e142bb9
Author: Michael Welling <mwelling@ieee.org>
Date: Fri May 8 13:31:01 2015 -0500
spi: omap2-mcspi: Add gpio_request and init CS
If GPIO chip select is specified, request the GPIO in the setup
function
and release it in the cleanup function.

Reverting this as well allowed boot.
