2011-12-19arm/tegra: Use bus notifiers to trigger pinmux setupStephen Warren
Currently, the Tegra pinmux is initialized at different times when booting with and without device tree: Without device tree: 1) Pinmux and GPIO drivers are registered. 2) Pinmux is configured. 3) All other drivers are registered. With device tree: 1) All drivers are registered and probed, including pinmux and GPIO. 2) Pinmux is configured. This change modifies board-pinmux.c to detect pinmux and GPIO driver registration using bus notifiers. This allows pinmux configuration to happen immediately after the pinmux driver is probed, irrespective of whether the pinmux driver is manually registered by board-pinmux.c, or if it's instantiated during device tree parsing. To support this with device tree, the pinmux init functions must be called prior to instantiating devices from device tree, so that the notifiers are set up before-hand.

2011-12-19arm/tegra: Refactor board-*-pinmux.c to share codeStephen Warren
This moves the implementation of *_pinmux_init() into a single location. The board-specific pinmux data is left in each board's own file. This will allow future changes that set up the pinmux in a more complex fashion to do so without duplicating that code in each board's pinmux file.

2011-12-19arm/tegra: Fix mistake in Trimslice's pinmuxStephen Warren
Pin group PTA does not support function RSVD3. However, the current pinmux driver doesn't check this when setting RSVD functions, and ends up writing 3 to the HW register. 3 is actually represented by function GMI, so update the pinmux table to request that instead in order to obtain the same register programming without requesting invalid configurations.

2011-12-19arm/tegra: Rework Seaboard-vs-Ventana pinmux tableStephen Warren
Rather than modifying seaboard_pinmux[] using ventana_pinmux[], split seaboard_pinmux[] into common_pinmux[] and seaboard_pinmux[], and then actually apply common_pinmux[] always, followed by the appopriate one of seaboard_pinmux[] or ventana_pinmux[].

2011-12-19arm/tegra: Harmony PCIe: Don't touch pinmuxStephen Warren
The Harmony pinmux table is already set up to mux the PCIe signals onto the appropriate pin groups. Don't manually fiddle with the pinmux in the Harmony PCIe setup code. Merge note: This will have a merge conflict with Peter De Schrijver's "arm/tegra: prepare pinmux code for multiple tegra variants" due to context. When merging the two, make sure to also remove the include of <mach/pinmux-tegra20.h> that his patch added, since it's no longer needed after this patch.

2011-12-19arm/tegra: Add AUXDATA for tegra-pinmux and tegra-gpioStephen Warren
The pinctrl device name is included in the pinctrl map table, and used as a parameter to pin_config_*() functions. Hence, it must be the same for non-DT and DT kernels. Add AUXDATA to cause this. The GPIO device name will be used by the pinmux/GPIO initialization code in a later patch, and needs to stay constant.

2011-12-19i2c: tegra: Support DVC controller in device treeStephen Warren
One of the Tegra I2C blocks is inside the DVC (Digital Voltage Controller) block. This block is identical to the rest of the I2C blocks, except that it only supports master mode, it has registers moved around, and it needs some extra init to get it into I2C mode. The register moves are handled by i2c_readl and i2c_writel This patch adds a new compatible value for controllers of this "DVC" type; I figured that this approach was reasonable, as opposed to adding an is-dvc property under the existing compatible value, since the HW truly is different. v2: Call of_device_is_compatible() to determine is_dvc, instead of storing the flag in tegra_i2c_of_match[]'s .data field.

2011-12-19Revert "mmc: enable runtime PM by default"Ohad Ben-Cohen
When SDIO runtime PM was originally introduced, we immediately faced two regressions with two different chipsets, and in response decided not to enable it by default. With the recent work on the 8686 we hoped we found all the gotchas, so 08da834 did make sense (at least experimentally). Unfortunately we now see that some setups out there still refuse to work when SDIO runtime PM is enabled by default (see http://www.spinics.net/lists/linux-mmc/msg11161.html), and obviously we can't live with these kind of regressions.

2011-12-19sctp: fix incorrect overflow check on autocloseXi Wang
Commit 8ffd3208 voids the previous patches f6778aab and 810c0719 for limiting the autoclose value. If userspace passes in -1 on 32-bit platform, the overflow check didn't work and autoclose would be set to 0xffffffff. This patch defines a max_autoclose (in seconds) for limiting the value and exposes it through sysctl, with the following intentions. 1) Avoid overflowing autoclose * HZ. 2) Keep the default autoclose bound consistent across 32- and 64-bit platforms (INT_MAX / HZ in this patch). 3) Keep the autoclose value consistent between setsockopt() and getsockopt() calls.
