* spi: rspi: Add rspi_data_{out,in,out_in}() helpersGeert Uytterhoeven2014-01-27
| | | | | | | | | Add helpers rspi_data_{out,in,out_in}() to write, read, or write and read data to/from the Data Register, taking care of waiting until data or space is available in the buffers.

* spi: rspi: Use core message handlingGeert Uytterhoeven2014-01-27
| | | | | | | | | | | | | Let the generic SPI core handle SPI messages, calling into our rspi_transfer_one() method. rspi_assert_ssl() and rspi_negate_ssl() are absorbed into rspi_prepare_message() and rspi_unprepare_message(), as they actually enable/disable the whole SPI function, instead of just (de)asserting the chip select line.

| * spi: sc18is602: Convert to use bits_per_word_maskAxel Lin2014-01-17
| | | | | | | | | | | | | | | | | | | | | | | | Since commit 543bb25 "spi: add ability to validate xfer->bits_per_word in SPI core", the driver can set bits_per_word_mask for the master then the SPI core will reject transfers that attempt to use an unsupported bits_per_word value. So we can remove the bits_per_word checking in sc18is602_check_transfer() and let SPI core handle the checking.

| * | spi: rspi: Fix NULL pointer dereference on SH7757Geert Uytterhoeven2013-12-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SH7757 doesn't pass platform data, in which case spi-rspi uses default parameters. However, commit 5ce0ba88650f2606244a761d92e2b725f4ab3583 ("spi: rcar: add Renesas QSPI support on RSPI") added a new user of the platform data, but forgot to check for its validity first, causing a NULL pointer dereference on SH7757. Add the missing check to fix this. Signed-off-by: Geert Uytterhoeven <geert+renesas@linux-m68k.org> Acked-by: Simon Horman <horms+renesas@verge.net.au> Signed-off-by: Mark Brown <broonie@linaro.org>

Since a s3c64xx based system is one of my primary development platforms it'd be really helpful if I could merge this into both ASoC and SPI, I've got some patches for ASoC ready to go converting to use dmaengine directly which help with multiplatform and there's some other dmaengine work for SPI in progress too. I've therefore made this signed tag, it'd be great if it could be merged into both arm-soc and those two trees.

Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.

The calls are added in the probe and remove handlers as the clk_enable() and clk_disable() calls are located in atomic context and there's no callback function in non-atomic context that can be used to prepare/unprepare the clock.
