2014-01-09i2c: nomadik: remove platform data headerLinus Walleij1-1/+23
The Nomadik I2C is now configured from the device tree on all platforms using this controller. Delete the platform data header and move the definitions into the driver so it is all contained in one single file.

2014-01-09i2c: nomadik: auto-calculate slave setup timeLinus Walleij1-12/+28
The Nomadik I2C controller needs to have the slave set-up time configured based off the clock used to drive the I2C bus block. Currently this is done with static assignments assuming that the block is clocked 48MHz which is pretty likely to be bug-prone. Calculate the SLSU from the equation given in the datasheet instead.

2014-01-03i2c: s3c2410: dont need CPU_FREQ transitions for exynos seriesNaveen Krishna Ch1-2/+2
For Exynos4 and Exynos5 SoCs from Samsung the i2c clock is based on a fixed 66 MHz peripheral clock, and therefore is completely independent of the cpu frequency. Thus, registering for a CPU freq notifier is very wasteful. This patch modifes the code such that, i2c bus registers to cpu_freq_transition only if CONFIG_CPU_FREQ_S3C24XX is enabled. This change should save a bunch of cpufreq transitions calls which does not apply to exynos SoCs.

This patch adds polling mode support for i2c-s3c2410 driver.The SATA PHY controller's CMU and TRSV block's are of I2C register map in exynos5250.These blocks can be configured using i2c. But i2c controller instance on which these block's sits lacks an interrupt line.Also the current i2c-s3c2410 driver is only interrupt driven, thus a polling mode support is required in the driver for supporting this controller.

git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/cleanup From Stephen Warren: ARM: tegra: implement common DMA and resets DT bindings This series converts the Tegra DTs and drivers to use the common/ standard DMA and reset bindings, rather than custom bindings. It also adds complete documentation for the Tegra clock bindings without actually changing any binding definitions. This conversion relies on a few sets of patches in branches from outside the Tegra tree: 1) A patch to add an DMA channel request API which allows deferred probe to be implemented. 2) A patch to implement a common part of the of_xlate function for DMA controllers. 3) Some ASoC patches (which in turn rely on (1) above), which support deferred probe during DMA channel allocation. 4) The Tegra clock driver changes for 3.14. Consequently, this branch is based on a merge of all of those external branches. In turn, this branch is or will be pulled into a few places that either rely on features introduced here, or would otherwise conflict with the patches: a) Tegra's own for-3.14/powergate and for-4.14/dt branches, to avoid conflicts. b) The DRM tree, which introduces new code that relies on the reset controller framework introduced in this branch, and to avoid conflicts. * tag 'tegra-for-3.14-dmas-resets-rework' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: (30 commits) spi: tegra: checking for ERR_PTR instead of NULL ASoC: tegra: update module reset list for Tegra124 clk: tegra: remove bogus PCIE_XCLK clk: tegra: remove legacy reset APIs ARM: tegra: remove legacy DMA entries from DT ARM: tegra: remove legacy clock entries from DT USB: EHCI: tegra: use reset framework Input: tegra-kbc - use reset framework serial: tegra: convert to standard DMA DT bindings serial: tegra: use reset framework spi: tegra: convert to standard DMA DT bindings spi: tegra: use reset framework staging: nvec: use reset framework i2c: tegra: use reset framework ASoC: tegra: convert to standard DMA DT bindings ASoC: tegra: allocate AHUB FIFO during probe() not startup() ASoC: tegra: call pm_runtime APIs around register accesses ASoC: tegra: use reset framework dma: tegra: register as an OF DMA controller dma: tegra: use reset framework ...

2013-11-17i2c: i2c-eg20t: do not print error message in syslog if no ACK receivedAndreas Werner1-22/+4
Using the i2c-eg20t driver and call i2cdetect or probe on the bus, the driver will print a lot of error messages if there was no ACK received. i2cdetect normally print a table with all the available devices. If there is no device on the address, the table will be empty. Currently with the i2c-eg20t driver, the table is not visible because the error messages destroy the table. Error message: pch_i2c_getack return -71 This patch prevent the driver to print the messages to syslog. The pch_i2c_wait_for_check_xfer function is the only one who is calling pch_i2c_getack, so we can delete the function and add the read to pch_i2c_wait_for_check_xfer. If no ACK is received, the Message will be printed as a dbg message. Fixed print message to be a one liner so we can grep for the error message. Tested on Intel Atom E6xx and Eg20t Chipset.

2013-11-01i2c: scmi: remove some bogus NULL checksDan Carpenter1-3/+3
"obj" can't be NULL here. We already know that "pkg->package.elements" gives us a valid pointer so the next pointer after that is also non-NULL. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-10-31i2c: sh_mobile & rcar: Enable the driver on all ARM platformsLaurent Pinchart1-2/+2
Renesas ARM platforms are transitioning from single-platform to multi-platform kernels using the new ARCH_SHMOBILE_MULTI. Make the driver available on all ARM platforms to enable it on both ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI, and increase build testing coverage with COMPILE_TEST.

2013-10-31i2c: sh_mobile: Convert to clk_prepare/unprepareLaurent Pinchart1-4/+4
Turn clk_enable() and clk_disable() calls into clk_prepare_enable() and clk_disable_unprepare() to get ready for the migration to the common clock framework. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

'of_match_ptr' is defined in linux/of.h. Include it explicitly to avoid build breakage in the future. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

Replace some instances of of_irq_map_one()/irq_create_of_mapping() and of_irq_to_resource() by the simpler equivalent irq_of_parse_and_map().

2013-10-10i2c: omap: Clear ARDY bit twiceTaras Kondratiuk1-0/+3
Initially commit cb527ede1bf6ff2008a025606f25344b8ed7b4ac "i2c-omap: Double clear of ARDY status in IRQ handler" added a workaround for undocumented errata ProDB0017052. But then commit 1d7afc95946487945cc7f5019b41255b72224b70 "i2c: omap: ack IRQ in parts" refactored code and missed one of ARDY clearings. So current code violates errata. It causes often i2c bus timeouts on my Pandaboard. This patch adds a second clearing in place.

2013-10-10i2c: i2c-stu300: replace platform_driver_probe to support deferred probingWolfram Sang1-6/+5
Subsystems like pinctrl and gpio rightfully make use of deferred probing at core level. Now, deferred drivers won't be retried if they don't have a .probe function specified in the driver struct. Fix this driver to have that, so the devices it supports won't get lost in a deferred probe. Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
