git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/soc From Stephen Warren: ARM: tegra: Common Clock Framework rework Tegra already supports the common clock framework, but had issues: 1) The clock driver was located in arch/arm/mach-tegra/ rather than drivers/clk/. 2) A single "Tegra clock" type was implemented, rather than separate clock types for PLL, mux, divider, ... type in HW. 3) Clock lookups by device drivers were still driven by device name and connection ID, rather than through device tree. This pull request solves all three issues. This required some DT changes to add clocks properties, and driver changes to request clocks more "correctly". Finally, this rework allows all AUXDATA to be removed from Tegra board files, and various duplicate clock lookup entries to be removed from the driver. This pull request is based on the previous pull request, with tag tegra-for-3.9-cleanup. * tag 'tegra-for-3.9-soc-ccf' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra: (31 commits) clk: tegra30: remove unused TEGRA_CLK_DUPLICATE()s clk: tegra20: remove unused TEGRA_CLK_DUPLICATE()s ARM: tegra30: remove auxdata ARM: tegra20: remove auxdata ASoC: tegra: remove auxdata staging: nvec: remove use of clk_get_sys ARM: tegra: paz00: add clock information to DT ARM: tegra: add clock properties to Tegra30 DT ARM: tegra: add clock properties to Tegra20 DT spi: tegra: do not use clock name to get clock ARM: tegra: remove legacy clock code ARM: tegra: migrate to new clock code clk: tegra: add clock support for Tegra30 clk: tegra: add clock support for Tegra20 clk: tegra: add Tegra specific clocks ARM: tegra: define Tegra30 CAR binding ARM: tegra: define Tegra20 CAR binding ARM: tegra: move tegra_cpu_car.h to linux/clk/tegra.h ARM: tegra: add function to read chipid ARM: tegra: fix compile error when disable CPU_IDLE ...

Add support for the PIO mode and mixed PIO/DMA mode support. The mixed PIO/DMA is the default mode of operation. This shall leverage overhead that the driver creates due to setting up DMA descriptors even for very short transfers. The current boundary between PIO/DMA 8 bytes, transfers shorter than 8 bytes are transfered by PIO, longer transfers use DMA. The performance of write transfers remains unchanged, while there is a minor improvement of read performance. Reading 16KB EEPROM with DMA-only operations gives a read speed of 39.5KB/s, while with then new mixed-mode the speed is blazing 40.6KB/s.

2013-01-28i2c-designware: always set the STOP bit after last byteMika Westerberg1-2/+14
If IC_EMPTYFIFO_HOLD_MASTER_EN is set to one, the DesignWare I2C controller doesn't generate STOP on the bus when the FIFO is empty. This violates the rules of Linux I2C stack as it requires that the STOP is issued once the i2c_transfer() is finished. However, there is no way to detect this from the hardware registers, so we must make sure that the STOP bit is always set once the last byte of the last message is transferred.

Commit 0bdfe0cb803dce699ff337c35d8e97ac355fa417 (i2c: omap: sanitize exit path) changed the interrupt handler to exit early and complete the transfer after the draining IRQ is handled. As a result, the ARDY may not be cleared properly, and it may cause all future I2C transfers to timeout with "timeout waiting for bus ready". This is reproducible at least with N900 when twl4030_gpio makes a long write (> FIFO size) during the probe (http://marc.info/?l=linux-omap&m=135818882610432&w=2). The fix is to continue until we get ARDY interrupt that completes the transfer. Tested with 3.8-rc4 + N900: 20 boots in a row without errors; without the patch the problem triggers after few reboots.

2013-01-21i2c: mxs: Fix misuse init_completionMarek Vasut1-1/+3
The init_completion() call does reinit not only the variable carrying the flag that the completion finished, but also initialized the waitqueue associated with the completion. On the contrary, the INIT_COMPLETION() call only reinits the flag. In case there was anything still stuck in the waitqueue, subsequent call to init_completion() would be able to create possible race condition. This patch uses the proper function and moves init_completion() into .probe() call of the driver, to be issued only once. Note that such scenario is impossible, since two threads can never enter the mxs_i2c_xfer_msg(), since whole this section is protected by mutex in I2C core.

The option allows you to remove TTY and compile without errors. This saves space on systems that won't support TTY interfaces anyway. bloat-o-meter output is below. The bulk of this patch consists of Kconfig changes adding "depends on TTY" to various serial devices and similar drivers that require the TTY layer. Ideally, these dependencies would occur on a common intermediate symbol such as SERIO, but most drivers "select SERIO" rather than "depends on SERIO", and "select" does not respect dependencies. bloat-o-meter output comparing our previous minimal to new minimal by removing TTY.

git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6 Pull MFS update from Samuel Ortiz: "This is the MFD patch set for the 3.8 merge window. We have several new drivers, most of the time coming with their sub devices drivers: - Austria Microsystem's AS3711 - Nano River's viperboard - TI's TPS80031, AM335x TS/ADC, - Realtek's MMC/memstick card reader - Nokia's retu We also got some notable cleanups and improvements: - tps6586x got converted to IRQ domains. - tps65910 and tps65090 moved to the regmap IRQ API. - STMPE is now Device Tree aware. - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ APIs and a conversion to the recently added PWM framework. - sta2x11 gained regmap support. Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts. Many due to __devinit/exit removal, others due to one or two of the new drivers also having come in through another tree. * tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (119 commits) mfd: tps6507x: Convert to devm_kzalloc mfd: stmpe: Update DT support for stmpe driver mfd: wm5102: Add readback of DSP status 3 register mfd: arizona: Log if we fail to create the primary IRQ domain mfd: tps80031: MFD_TPS80031 needs to select REGMAP_IRQ mfd: tps80031: Add terminating entry for tps80031_id_table mfd: sta2x11: Fix potential NULL pointer dereference in __sta2x11_mfd_mask() mfd: wm5102: Add tuning for revision B mfd: arizona: Defer patch initialistation until after first device boot mfd: tps65910: Fix wrong ack_base register mfd: tps65910: Remove unused data mfd: stmpe: Get rid of irq_invert_polarity mfd: ab8500-core: Fix invalid free of devm_ allocated data mfd: wm5102: Mark DSP memory regions as volatile mfd: wm5102: Correct default for LDO1_CONTROL_2 mfd: arizona: Register haptics devices mfd: wm8994: Make current device behaviour the default mfd: tps65090: MFD_TPS65090 needs to select REGMAP_IRQ mfd: Fix stmpe.c build when OF is not enabled mfd: jz4740-adc: Use devm_kzalloc ...
2012-12-17i2c-piix4: Convert dev_printk(KERN_<LEVEL> to dev_<level>(Joe Perches1-3/+2
dev_<level> calls take less code than dev_printk(KERN_<LEVEL> and reducing object size is good. Coalesce formats for easier grep. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2012-12-17i2c-i801: Enable interrupts for all post-ICH5 chipsJean Delvare1-10/+1
I did not receive a single bug report after interrupt support was added for a limited number of chips. So I'd say the code is good and should be enabled for all supported chips, that is: ICH5 and later. Signed-off-by: Jean Delvare <khali@linux-fr.org> Reviewed-by: Daniel Kurtz <djkurtz@chromium.org>
