* drivers/video/ssd1307fb.c: fix bit order bug in the byte translation functionMaxime Ripard2013-01-111-2/+2
| | | | | | | | | | | | | | | | | | This was leading to a strange behaviour when using the fbcon driver on top of this one: the letters were in the right order, but each letter had a vertical symmetry. This was because the addressing was right for the byte, but the addressing of each individual bit was inverted.

Here are a bunch of fixes for a number of platforms: - A couple of small fixes for Nomadik - A larger set of changes for kirkwood/mvebu - uart driver selection, dt clocks, gpio-poweroff fixups, a few __init annotation fixes and some error handling improvement in their xor dma driver. - i.MX had a couple of minor fixes (and a critical one for flexcan2 clock setup) - MXS has a small board fix and a framebuffer bugfix - A set of fixes for Samsung Exynos, fixing default bootargs and some Exynos5440 clock issues - A set of OMAP changes including PM fixes and a few sparse warning fixups All in all a bit more positive code delta than we'd ideally want to see here, mostly from the OMAP PM changes, but nothing overly crazy." * tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (44 commits) ARM: clps711x: Fix bad merge of clockevents setup ARM: highbank: save and restore L2 cache and GIC on suspend ARM: highbank: add a power request clear ARM: highbank: fix secondary boot and hotplug ARM: highbank: fix typos with hignbank in power request functions ARM: dts: fix highbank cpu mpidr values ARM: dts: add device_type prop to cpu nodes on Calxeda platforms ARM: mx5: Fix MX53 flexcan2 clock ARM: OMAP2+: am33xx-hwmod: Fix wrongly terminated am33xx_usbss_mpu_irqs array pinctrl: mvebu: make pdma clock on dove mandatory ARM: Dove: Add pinctrl clock to DT dma: mv_xor: fix error handling for clocks dma: mv_xor: fix error handling of mv_xor_channel_add() arm: mvebu: Add missing ; for cpu node. arm: mvebu: Armada XP MV78230 has only three Ethernet interfaces arm: mvebu: Armada XP MV78230 has two cores, not one clk: mvebu: Remove inappropriate __init tagging ARM: Kirkwood: Use fixed-regulator instead of board gpio call ARM: Kirkwood: Fix missing sdio clock ARM: Kirkwood: Switch TWSI1 of 88f6282 to DT clock providers ...
| * video: mxsfb: fix crash when unblanking the displayLothar Waßmann2013-01-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The VDCTRL4 register does not provide the MXS SET/CLR/TOGGLE feature. The write in mxsfb_disable_controller() sets the data_cnt for the LCD DMA to 0 which obviously means the max. count for the LCD DMA and leads to overwriting arbitrary memory when the display is unblanked.

* | Drivers: video: remove __dev* attributes.Greg Kroah-Hartman2013-01-03135-1129/+1017
|/ | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

See threads at http://marc.info/?l=linux-fbdev-devel&m=124345080216952&w=2 and https://lists.ozlabs.org/pipermail/linuxppc-dev/2009-June/072672.html for more details. This patch adds support for GXT4000P and GXT6500P cards found on some IBM pSeries machines. GXT4000P/6000P and GXT4500P/6500P couples are identical from software's point of view and are based on the same Raster Engine (RC1000), except for a different reference clock for the PLL. GXT6x00P models are equipped with an additional Geometry Engine (GT1000) but this driver doesn't use it.

In this case, pca953x_gpio_set_value() can be called to control gpio, and pca953x_setup_gpio() sets can_sleep flag. Therefore, gpio_set_value_cansleep() should be used in order to avoid WARN_ON on akita machines. Akita is the only exception in this case since other users of corgi_lcd access backlight gpio controls through a different gpio expander which does not set the can_sleep flag.

Period of the PWM is configurable in the platform side. Platform specific functions are unnecessary anymore because generic PWM functions are used inside the driver. (PWM input mode) To set the brightness, new lp855x_pwm_ctrl() is used. If a PWM device is not allocated, devm_pwm_get() is called. The PWM consumer name is from the chip name such as 'lp8550' and 'lp8556'. To get the brightness value, no additional handling is required. Just the value of 'props.brightness' is returned. If the PWM driver is not ready while initializing the LP855x driver, it's OK. The PWM device can be retrieved later, when the brightness value is changed. Documentation is updated with an example.

| | * | | | OMAPDSS: fix TV-out issue with DSI PLLTomi Valkeinen2012-12-131-0/+16

This works fine, for DPI, but has a nasty side effect on OMAP3: On OMAP3 the same clock is used for DISPC fclk and LCD output. Thus, after the above patch, DSI PLL is used for DISPC and LCD output. If TV-out is used, the TV-out needs DISPC. And if DPI is turned off, the DSI PLL is also turned off, disabling DISPC. For this to work, we'd need proper DSS internal clock handling, with refcounts, which is a non-trivial project. This patch fixes the issue for now by disabling the use of DSI PLL for DPI on OMAP3.
