Among the bigger ones: - Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have lacked active support for quite a while, and after asking around nobody showed interest in keeping them around. If needed, they could be resurrected in the future but it's more likely that we would prefer reintroduction of them as DT and multiplatform-enabled platforms instead. - OMAP4 controller code register define diet. They defined a lot of registers that were never actually used, etc. - Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate) to drivers/soc so it can be shared with 64-bit code. This also converts them over to traditional driver models where possible. - Removal of legacy gpio-samsung driver, since the last users have been removed (moved to pinctrl) Plus a bunch of smaller changes for various platforms that sort of dissapear in the diffstat for the above. clps711x cleanups, shmobile header file refactoring/moves for multiplatform friendliness, some misc cleanups, etc" * tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (117 commits) drivers: CCI: Correct use of ! and & video: clcd-versatile: Depend on ARM video: fix up versatile CLCD helper move MAINTAINERS: Add sdhci-st file to ARCH/STI architecture ARM: EXYNOS: Fix build breakge with PM_SLEEP=n MAINTAINERS: Remove Kirkwood ARM: tegra: Convert PMC to a driver soc/tegra: fuse: Set up in early initcall ARM: tegra: Always lock the CPU reset vector ARM: tegra: Setup CPU hotplug in a pure initcall soc/tegra: Implement runtime check for Tegra SoCs soc/tegra: fuse: fix dummy functions soc/tegra: fuse: move APB DMA into Tegra20 fuse driver soc/tegra: Add efuse and apbmisc bindings soc/tegra: Add efuse driver for Tegra ARM: tegra: move fuse exports to soc/tegra/fuse.h ARM: tegra: export apb dma readl/writel ARM: tegra: Use a function to get the chip ID ARM: tegra: Sort includes alphabetically ARM: tegra: Move includes to include/soc/tegra ...

|/ / | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the chip select function. Chip select should instead be supported using GPIOs, defining the DT entry "cs-gpios", and letting the SPI core assert/deassert the chip select as it sees fit. The chip select control inside the controller is buggy. It is supposed to automatically assert the chip select based on the activity in the controller, but it is buggy and doesn't work at all. So instead we elect to use GPIOs. Signed-off-by: Andy Gross <agross@codeaurora.org> Signed-off-by: Mark Brown <broonie@linaro.org>

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.

Binding documentation: - Add future-proof "renesas,msiof-<soctype>" compatible values, - The default for "renesas,rx-fifo-size" is 256 on R-Car H2 and M2, - "renesas,tx-fifo-size" and "renesas,rx-fifo-size" are deprecated for soctype-specific bindings, - Add example bindings. Implementation: - MSIOF on R-Car H2 and M2 requires the transmission of dummy data if data is being received only (cfr. "Set SICTR.TSCKE to 1" and "Write dummy transmission data to SITFDR" in paragraph "Transmit and Receive Procedures" of the Hardware User's Manual). - As RX depends on TX, MSIOF on R-Car H2 and M2 also lacks the RSCR register (Receive Clock Select Register), and some bits in the RMDR1 (Receive Mode Register 1) and TMDR2 (Transmit Mode Register 2) registers. - Use the recently introduced SPI_MASTER_MUST_TX flag to enable support for dummy transmission in the SPI core, and to differentiate from other MSIOF implementations in code paths that need this. - New DT compatible values ("renesas,msiof-r8a7790" and "renesas,msiof-r8a7791") are added, as well as new platform device names ("spi_r8a7790_msiof" and "spi_r8a7791_msiof"). - The default RX FIFO size is 256 words on R-Car H2 and M2. This is loosely based on a set of patches from Takashi Yoshii <takasi-y@ops.dti.ne.jp>.

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 ...

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 743179849015 (of_spi: add generic binding support to specify cs gpio) introduced generic binding for gpio chip-select. The cs_gpio struct field, however, is an internal implementation detail of the Linux SPI subsystem, and should not be mentioned in the device tree binding documentation. Mention the previously defined cs-gpios master node property instead. Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Mark Brown <broonie@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update all the Tegra DT bindings to require the standard dmas/dma-names properties rather than non-standard nvidia,dma-request-selector property. This is a DT-ABI-incompatible change. It is the second of two changes required for me to consider the Tegra DT bindings as stable, the other being the previous conversion to the common reset bindings.
