2012-09-06spi: spi-sh-hspi: drop frees of devm_ alloc'd dataJulia Lawall1-4/+1
devm free functions should not have to be explicitly used. A semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ @@ ( * devm_kfree(...); | * devm_free_irq(...); | * devm_iounmap(...); | * devm_release_region(...); | * devm_release_mem_region(...); ) // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-03-15spi: sh-hspi: modify write/read methodKuninori Morimoto1-69/+24
Current sh-hspi had wrong write/read method which was not linux standard. If spi_transfer requests tx[2], rx[2] len=2, then, driver should run tx[0], rx[0], tx[1], rx[1]. But current sh-hspi runs tx[0], tx[1], rx[0], rx[1]. This patch fixes it up.

2012-03-15spi: sh-hspi: control spi clock more correctlyKuninori Morimoto1-16/+70
Current sh-hspi had used platform-specific speed. This patch remove it, and use spi_transfer specific speed. It removes unnecessary flags from struct sh_hspi_info, but struct sh_hspi_info is still exist, since sh-hspi needs platform info in the future.

2012-03-09spi: Add SuperH HSPI prototype driverKuninori Morimoto1-0/+364
This patch adds SuperH HSPI driver. It is still prototype driver, but has enough function at this point. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
