From: Geert Uytterhoeven Date: Tue, 25 Feb 2014 10:21:13 +0000 (+0100) Subject: spi: sh-msiof: Use core message handling instead of spi-bitbang X-Git-Tag: v3.15-rc1~147^2~2^5~3 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1bd6363bc0c69ff6120b53daa35cf9459c3628ad;p=pandora-kernel.git spi: sh-msiof: Use core message handling instead of spi-bitbang The only remaining feature of spi-bitbang used by this driver is the chipselect() callback, which just does conditional GPIO. This is handled fine by the SPI core's spi_set_cs(), hence switch the driver to use the core message handling through our own transfer_one() method. As the (optional) GPIO CS is no longer deasserted at spi_master.setup() time (through spi_bitbang_setup() and the spi_bitbang.chipselect() callback), we now have to take care of that ourselves. Remove the call to spi_master_put() in sh_msiof_spi_remove(), as our SPI master is now registered using devm_spi_register_master() (spi_bitbang_start() uses the non-managed version).
