2014-08-31spi/drivers: Restrict COMPILE_TEST by HAS_DMA where neededGeert Uytterhoeven1-2/+5
commit dd1053a93fdc11d4 ("spi/drivers: Enable build of drivers with COMPILE_TEST") allows compile-testing drivers on platforms they're not meant for. However, adding "|| COMPILE_TEST" bypasses all other implicit dependencies assumed by the platform dependencies before, like HAS_DMA.

As of commit ab116a4df4942c78c189d9b0744dd940ab9e00b9 ("dmaengine: shdma: fix a build failure on platforms with no DMA support"), the DMA filter function shdma_chan_filter() is sufficiently abstracted to allow building without DMA support. Hence drop the SH_DMAE_BASE dependency on SUPERH. Also increase build coverage by allowing the driver to be enabled if COMPILE_TEST=y.

Commit 8fc1b0f87d9f ("ARM: qcom: Split Qualcomm support into legacy and multiplatform") removed Kconfig symbol ARCH_MSM_DT. But that commit left one (optional) dependency on ARCH_MSM_DT untouched. Three Kconfig symbols used to depend on ARCH_MSM_DT: ARCH_MSM8X60, ARCH_MSM8960, and ARCH_MSM8974. These three symbols now depend on ARCH_QCOM.

2014-02-27spi: sh-msiof: Use core message handling instead of spi-bitbangGeert Uytterhoeven1-1/+0
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).

The older Allwinner SoCs (A10, A13, A10s and A20) all have the same SPI controller. Unfortunately, this SPI controller, even though quite similar, is significantly different from the recently supported A31 SPI controller (different registers offset, split/merged registers, etc.). Supporting both controllers in a single driver would be unreasonable, hence the addition of a new driver. Like its more recent counterpart, it supports DMA, but the driver only does PIO until we have a dmaengine driver for this platform.

Pull spi updates from Mark Brown: "A respun version of the merges for the pull request previously sent with a few additional fixes. The last two merges were fixed up by hand since the branches have moved on and currently have the prior merge in them. Quite a busy release for the SPI subsystem, mostly in cleanups big and small scattered through the stack rather than anything else: - New driver for the Broadcom BC63xx HSSPI controller - Fix duplicate device registration for ACPI - Conversion of s3c64xx to DMAEngine (this pulls in platform and DMA changes upon which the transiton depends) - Some small optimisations to reduce the amount of time we hold locks in the datapath, eliminate some redundant checks and the size of a spi_transfer - Lots of fixes, cleanups and general enhancements to drivers, especially the rspi and Atmel drivers" * tag 'spi-v3.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (112 commits) spi: core: Fix transfer failure when master->transfer_one returns positive value spi: Correct set_cs() documentation spi: Clarify transfer_one() w.r.t. spi_finalize_current_transfer() spi: Spelling s/finised/finished/ spi: sc18is602: Convert to use bits_per_word_mask spi: Remove duplicate code to set default bits_per_word setting spi/pxa2xx: fix compilation warning when !CONFIG_PM_SLEEP spi: clps711x: Add MODULE_ALIAS to support module auto-loading spi: rspi: Add missing clk_disable() calls in error and cleanup paths spi: rspi: Spelling s/transmition/transmission/ spi: rspi: Add support for specifying CPHA/CPOL spi/pxa2xx: initialize DMA channels to -1 to prevent inadvertent match spi: rspi: Add more QSPI register documentation spi: rspi: Add more RSPI register documentation spi: rspi: Remove dependency on DMAE for SHMOBILE spi/s3c64xx: Correct indentation spi: sh: Use spi_sh_clear_bit() instead of open-coded spi: bitbang: Grammar s/make to make/to make/ spi: sh-hspi: Spelling s/recive/receive/ spi: core: Improve tx/rx_nbits check comments ...

Pull ARM SoC cleanups from Olof Johansson: "This is the branch where we usually queue up cleanup efforts, moving drivers out of the architecture directory, header file restructuring, etc. Sometimes they tangle with new development so it's hard to keep it strictly to cleanups. Some of the things included in this branch are: * Atmel SAMA5 conversion to common clock * Reset framework conversion for tegra platforms - Some of this depends on tegra clock driver reworks that are shared with Mike Turquette's clk tree. * Tegra DMA refactoring, which are shared branches with the DMA tree. * Removal of some header files on exynos to prepare for multiplatform" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (169 commits) ARM: mvebu: move Armada 370/XP specific definitions to armada-370-xp.h ARM: mvebu: remove prototypes of non-existing functions from common.h ARM: mvebu: move ARMADA_XP_MAX_CPUS to armada-370-xp.h serial: sh-sci: Rework baud rate calculation serial: sh-sci: Compute overrun_bit without using baud rate algo serial: sh-sci: Remove unused GPIO request code serial: sh-sci: Move overrun_bit and error_mask fields out of pdata serial: sh-sci: Support resources passed through platform resources serial: sh-sci: Don't check IRQ in verify port operation serial: sh-sci: Set the UPF_FIXED_PORT flag serial: sh-sci: Remove duplicate interrupt check in verify port op serial: sh-sci: Simplify baud rate calculation algorithms serial: sh-sci: Remove baud rate calculation algorithm 5 serial: sh-sci: Sort headers alphabetically ARM: EXYNOS: Kill exynos_pm_late_initcall() ARM: EXYNOS: Consolidate selection of PM_GENERIC_DOMAINS for Exynos4 ARM: at91: switch Calao QIL-A9260 board to DT clk: at91: fix pmc_clk_ids data type attriubte PM / devfreq: use inclusion <mach/map.h> instead of <plat/map-s5p.h> ARM: EXYNOS: remove <mach/regs-clock.h> for exynos ...

2014-01-13spi: rspi: Remove dependency on DMAE for SHMOBILEGeert Uytterhoeven1-1/+1
On ARM-based SHMOBILE, the rspi driver builds and works fine without the DMA controller driver, hence relax the dependencies. Signed-off-by: Geert Uytterhoeven <geert+renesas@linux-m68k.org> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-01-09spi/davinci: Don't select EDMASekhar Nori1-1/+0
There is no need to force selection of TI EDMA DMA engine driver when DaVinci SPI driver is selected. The driver builds just fine even with CONFIG_TI_EDMA disabled. Forcing this selection causes warnings of the sort: warning: (ARCH_KEYSTONE && SPI_DAVINCI) selects TI_EDMA which has unmet direct dependencies (DMADEVICES && (ARCH_DAVINCI || ARCH_OMAP || ARCH_KEYSTONE)) This reverts commit b5f14330590118e6a0659255476c0f24ab681e05. Reported-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Mark Brown <broonie@linaro.org>
