2013-05-27[media] drivers/staging: davinci: vpfe: fix dependency for building the driverLad, Prabhakar
from commit 3778d05036cc7ddd983ae2451da579af00acdac2 [media: davinci: kconfig: fix incorrect selects] VIDEO_VPFE_CAPTURE was removed but there was a negative dependancy for building the DM365 VPFE MC based capture driver (VIDEO_DM365_VPFE), This patch fixes this dependency by replacing the VIDEO_VPFE_CAPTURE with VIDEO_DM365_ISIF, so as when older DM365 ISIF v4l driver is selected the newer media controller driver for DM365 isnt visible.

2013-05-16staging/solo6x10: depend on CONFIG_FONTSArnd Bergmann
The new SOLO6X10 driver needs the built-in console fonts, specifically the VGA8x16 font and building it without console support results in a link error error. drivers/built-in.o: In function `solo_osd_print': :(.text+0x7d3424): undefined reference to `find_font' This adds a dependency on the CONFIG_FONTS symbol and changes the console code to always build the base driver even if there are no specific fonts built-in.

2013-05-02Merge branch 'i2c/for-next' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c changes from Wolfram Sang: - an arbitration driver. While the driver is quite simple, it caused discussion if we need additional arbitration on top of the one specified in the I2C standard. Conclusion is that I accept a few generic mechanisms, but not very specific ones. - the core lost the detach_adapter() call. It has no users anymore and was in the way for other cleanups. attach_adapter() is sadly still there since there are users waiting to be converted. - the core gained a bus recovery infrastructure. I2C defines a way to recover if the data line is stalled. This mechanism is now in the core and drivers can now pass some data to make use of it. - bigger driver cleanups for designware, s3c2410 - removing superfluous refcounting from drivers - removing Ben Dooks as second maintainer due to inactivity. Thanks for all your work so far, Ben! - bugfixes, feature additions, devicetree fixups, simplifications... * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (38 commits) i2c: xiic: must always write 16-bit words to TX_FIFO i2c: octeon: use HZ in timeout value i2c: octeon: Fix i2c fail problem when a process is terminated by a signal i2c: designware-pci: drop superfluous {get|put}_device i2c: designware-plat: drop superfluous {get|put}_device i2c: davinci: drop superfluous {get|put}_device MAINTAINERS: Ben Dooks is inactive regarding I2C i2c: mux: Add i2c-arb-gpio-challenge 'mux' driver i2c: at91: convert to dma_request_slave_channel_compat() i2c: mxs: do error checking and handling in PIO mode i2c: mxs: remove races in PIO code i2c-designware: switch to use runtime PM autosuspend i2c-designware: use usleep_range() in the busy-loop i2c-designware: enable/disable the controller properly i2c-designware: use dynamic adapter numbering on Lynxpoint i2c-designware-pci: use managed functions pcim_* and devm_* i2c-designware-pci: use dev_err() instead of printk() i2c-designware: move to managed functions (devm_*) i2c: remove CONFIG_HOTPLUG ifdefs i2c: s3c2410: Add SMBus emulation for block read ...

2013-04-02i2c: Ignore return value of i2c_del_adapter()Lars-Peter Clausen
i2c_del_adapter() always returns 0. So all checks testing whether it will be non zero will always evaluate to false and the conditional code is dead code. This patch updates all callers of i2c_del_mux_adapter() to ignore the return value and assume that it will always succeed (which it will). In a subsequent patch the return type of i2c_del_adapter() will be made void.

On powerpc the maximum size for the ioctl argument is 8191, and it was 8192. However, the 64x64 array of threshold values is more than is actually needed in practice for PAL and NTSC formats.

2013-03-25[media] solo6x10: convert the display node to vb2Hans Verkuil
As a consequence the ioctl op has been replaced by unlocked_ioctl. Since we are now using the core lock the locking scheme has been simplified as well. The main reason for converting this driver to vb2 was that the locking scheme in v4l2.c was hopeless. It was easier to just convert the driver then to try and salvage a threading and videobuf nightmare. The videobuf2 framework is far, far superior compared to the old videobuf.

2013-03-25[media] solo6x10: move global fields in solo_enc_fh to solo_enc_devHans Verkuil
All fields in solo_enc_fh do not belong there since they refer to global properties. After moving all these fields to solo_enc_dev the solo_dev_fh struct can be removed completely. Note that this also kills the 'listener' feature of this driver. This feature (where multiple filehandles can read the video) is illegal in the V4L2 API. Do this in userspace: it's much more efficient to copy memory than it is to DMA to every listener.
