2012-12-19spi/sh-hspi: fix return value check in hspi_probe().Cyril Roelandt
According to its documentation, clk_get() returns a "valid IS_ERR() condition containing errno", so we should call IS_ERR() rather than a NULL check.

2012-12-06spi: Remove SPI_BUFSIZ restriction on spi_write_then_read()Mark Brown
In order to avoid constantly allocating and deallocating there is a fixed buffer which spi_write_then_read() uses for transfers, with an early error check to ensure that the transfer fits within the buffer. This limits the size of transfers to this size, currently max(32, SMP_CACHE_BYTES). Since we can dynamically allocate and in fact already have a fallback to do so when there is contention for the fixed buffer remove this restriction and instead dynamically allocate a suitably sized buffer if the transfer won't fit.

2012-11-29of/spi: Honour "status=disabled" property of deviceAlexander Sverdlin
Currently of_register_spi_devices() function registers all SPI devices, independetly from their status property in device tree. According to "ePAPR 1.1" spec, device should only be registered if there is no "status" property, or it has "ok" (or "okay") value (see of_device_is_available()). In case of "platform devices", of_platform_device_create_pdata() checks for "status" and ensures that disabled devices are not pupulated. But such check for SPI buses was missing until now. Fix it.

2012-11-23spi/sh-hspi: add CS manual control supportPhil Edworthy

2012-11-21of_spi: add generic binding support to specify cs gpioJean-Christophe PLAGNIOL-VILLARD
This will allow to use gpio for chip select with no modification in the driver binding When use the cs-gpios, the gpio number will be passed via the cs_gpio field and the number of chip select will automatically increased with max(hw cs, gpio cs). So if for example the controller has 2 CS lines, and the cs-gpios property looks like this: cs-gpios = <&gpio1 0 0> <0> <&gpio1 1 0> <&gpio1 2 0>; Then it should be configured so that num_chipselect = 4 with the following mapping: cs0 : &gpio1 0 0 cs1 : native cs2 : &gpio1 1 0 cs3 : &gpio1 2 0 Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Cc: devicetree-discuss@lists.ozlabs.org Cc: spi-devel-general@lists.sourceforge.net Signed-off-by: Richard Genoud <richard.genoud@gmail.com> [grant.likely: fixed up type of cs count so min() can do type checking] Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

[Originally sent by Ulf as two changes, squashed down into one with a redone changelog, thanks to Russell King for analysis. -- broonie] This reverts commit 688723 (spi/pl022: enable runtime PM) and commit 2fb30d (spi/pl022: fix spi-pl022 pm enable at probe). Commit "spi/pl022: enable runtime PM" introduced runtime PM issues as it interacted badly with the work Russell King had done to move core runtime PM handling into the bus. Due to that commit, "spi/pl022: fix spi-pl022 pm enable at probe" was merged to fix part of those issues. Instead of adding another fix, let's clean up and revert everything back to when it was already fine.
