* Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linuxLinus Torvalds2012-10-10

In fact, the old driver gets removed; I am okay with this approach since the old driver was depending on BROKEN and its limitations made it practically unusable, so people used bitbanging instead. But even if there are users, there is no platform_data or module parameter which would need to be converted. It is just another driver doing I2C transfers, just way better. Modifications of arch/arm/at91 related files have proper acks from the maintainer. - new driver for R-Car I2C - devicetree and generic_clock conversions and fixes - usual driver fixes and changes. The rework patches have come a long way and lots of people have been involved in creating/testing them. Most patches have been in linux-next at least since 3.6-rc5. A few have been added in the last week, I have to admit. An unexpected (but welcome :)) peak in private life is the cause for that. The "late" patches shouldn't cause any merge conflicts and I will have a special eye on them during the stabilization phase. This is an exception and I want to have the patches in place properly in time again for the next kernels." * 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux: (44 commits) MXS: Implement DMA support into mxs-i2c i2c: add Renesas R-Car I2C driver i2c: s3c2410: use clk_prepare_enable and clk_disable_unprepare ARM: OMAP: convert I2C driver to PM QoS for MPU latency constraints i2c: nomadik: Add Device Tree support to the Nomadik I2C driver i2c: algo: pca: Fix chip reset function for PCA9665 i2c: mpc: Wait for STOP to hit the bus i2c: davinci: preparation for switch to common clock framework omap-i2c: fix incorrect log message when using a device tree i2c: omap: sanitize exit path i2c: omap: switch over to autosuspend API i2c: omap: remove unnecessary pm_runtime_suspended check i2c: omap: switch to threaded IRQ support i2c: omap: remove redundant status read i2c: omap: get rid of the "complete" label i2c: omap: resize fifos before each message i2c: omap: simplify IRQ exit path i2c: omap: always return IRQ_HANDLED i2c: omap: simplify errata check i2c: omap: bus: add a receiver flag ...

This patch: - updates the platform support code to use AT91SAM9X_WATCHDOG. - includes <linux/io.h> to fix compile error (same fix as was applied to at91rm9200_wdt.c) - fixes comment regarding watchdog clock-rates in at91rm9200.

* [ARM] 4909/1: [AT91] Timer/Counter Block platform_devicesAndrew Victor2008-04-04
| | | | | | | | | | Register platform_devices for the Timer/Counter Block peripherals found on the AT91RM9200, SAM9 & CAP9 processors. Original patch from David Brownell. Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4908/1: [AT91] RTT platform_device fixAndrew Victor2008-04-04
| | | | | | | | | | | | | The RTT-as-RTC driver will search for the user-specified RTT peripheral via ID number (0 .. 1). Therefore if the processor only contains a single RTT peripheral, we need to set its platform_device.id to "0" instead of "-1". Also add the missing platform_device resource for the CAP9 processor. Bug reported by Sedji Gaouaou. Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4902/1: [AT91] SAM9/CAP9 memory controller headerAndrew Victor2008-04-04
| | | | | | | | | | | | | | The AT91CAP9 processor includes the same Static Memory Controller (SMC) peripheral as the SAM9 processors, but replaces the SDRAM Controller with a DDR/SDR Controller (DDRSDRC). This patch splits the existing include/asm-arm/arch-at91/at91sam926x_mc.h into at91sam9_sdramc.h and at91sam9_smc.h. It also adds an at91cap9_ddrsdr.h for the DDRSDRC controller.

* [ARM] 4738/1: at91sam9261: Remove udc pullup enabling in board initialisationChristian Glindkamp2008-01-26
| | | | | | | | | | | Currently the udc pullup is enabled by default on boot. If the device is connected to a host at this time, the host starts the negotiation before the udc/gadget driver is ready to handle it.

* [ARM] 4758/1: [AT91] LEDsAndrew Victor2008-01-26
| | | | | | | | | | | Move the LED initialization code out of the various *_devices.c files, and into leds.c. Also add support for NEW_LEDs. Patch from David Brownell. Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4757/1: [AT91] UART initializationAndrew Victor2008-01-26
| | | | | | | | | | | | | | | | Modify the UART initialization to allow the board-initialization code to specify which pins are connected, and which pins should therefore be initialized. The current at91_init_serial() will continue to work as-is, but is marked as "deprecated" and will be removed once the board-specific files has been updated to use the new interface. As in the AVR32 code, we assume that the TX and RX pins will always be initialized. Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4755/1: [AT91] NAND updateAndrew Victor2008-01-26
| | | | | | | | | | | | Map the complete memory region (SZ_256M) as is done on the other AT91 processors. The SMC_SMARTMEDIA bit should be set in the EBI controller to enable the hardware NAND logic.
