2013-08-28pinctrl: tegra: Convert to devm_ioremap_resourceAxel Lin
Using the new devm_ioremap_resource() we can greatly simplify resource handling. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-08-28pinctrl: rockchip: Simplify pin_to_bank equationAxel Lin
If (b->pin_base + b->nr_pins - 1) < pin is true, pin >= b->pin_base is always true because b->nr_pins is never less than 0. Thus this patch simplify the equation.

2013-08-28pinctrl: core: Add proper mutex lock in pinctrl_request_gpioAxel Lin
This one is missed in commit 42fed7ba "pinctrl: move subsystem mutex to pinctrl_dev struct". I think this fixes the race between pin_free() and pin_request() calls. It protects accessing the members of pctldev->desc. (e.g. update desc->mux_usecount, desc->gpio_owner, desc->mux_owner, etc) Current code grabs pctldev->mutex before calling pinmux_free_gpio(), but did not grab the mutex while calling pinmux_request_gpio().

2013-08-28batman-adv: set skb priority according to contentSimon Wunderlich
The skb priority field may help the wireless driver to choose the right queue (e.g. WMM queues). This should be set in batman-adv, as this information is only available here. This patch adds support for IPv4/IPv6 DS fields and VLAN PCP. Note that only VLAN PCP is used if a VLAN header is present. Also initially set TC_PRIO_CONTROL only for self-generated packets, and keep the priority set by higher layers.

2013-08-28i2c: designware: get SDA hold time, HCNT and LCNT configuration from ACPIMika Westerberg
Some Intel LPSS I2C devices make the SDA hold time and *CNT parameters available via SSCN (standard mode) and FMCN (fast mode) ACPI methods. Implement support for this so that we check whether an ACPI method exists and if it does, fill in the SDA hold time and *CNT values to the device private structure for core to use.

2013-08-28i2c: designware: make HCNT/LCNT values configurableMika Westerberg
The DesignWare I2C controller has high count (HCNT) and low count (LCNT) registers for each of the I2C speed modes (standard and fast). These registers are programmed based on the input clock speed in the driver. The current code calculates these values based on the input clock speed and tries hard to meet the I2C bus timing requirements. This could result non-optimal values with regarding to the bus speed. For example on Intel BayTrail we get bus speed of 315.41kHz which is ~20% slower than we would expect (400kHz) in fast mode (even though the timing requirements are met). This patch makes it possible for the platform code to pass more optimal HCNT/LCNT values to the core driver if they are known beforehand. If these are not set we use the calculated and more conservative values.

Use the new display drivers for OMAP3 Overo board. The new OMAP display drivers were merged for 3.11, and we can now change the board files to use the new ones and phase out the old ones. Note that the LCD add-on boards for lcd43 and lcd35 use the same GPIOs for the panels. This means that both panel devices cannot be probed at the same time. DT will handle this correctly, i.e. the DT data will contain the panel device only for the add-on board that is attached. However, for the board file we need a hackish solution: We parse the kernel boot command line, and see whether lcd43 or lcd35 is set as a default display, and add the given one. Or, if neither is given, default to lcd43. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
2013-08-28ARM: OMAP: 4430SDP: remove picodlp device dataTomi Valkeinen
4430SDP board has an option for a PicoDLP mini-projector. PicoDLP cannot be used at the same time as the second LCD, and there are GPIOs that need to be set/unset when changing the used display. Managing that kind of board specific setup is not simple without board file callbacks. As only some 4430SDP boards actually have the PicoDLP installed, and 4430SDP boards are not that common in the first place, let's remove PicoDLP data from the board file.

2013-08-28xfrm: Fix potential null pointer dereference in xdst_queue_outputSteffen Klassert
The net_device might be not set on the skb when we try refcounting. This leads to a null pointer dereference in xdst_queue_output(). It turned out that the refcount to the net_device is not needed after all. The dst_entry has a refcount to the net_device before we queue the skb, so it can't go away. Therefore we can remove the refcount on queueing to fix the null pointer dereference. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
