2013-08-30ARM: KVM: vgic: fix GICD_ICFGRn accessMarc Zyngier
All the code in handle_mmio_cfg_reg() assumes the offset has been shifted right to accomodate for the 2:1 bit compression, but this is only done when getting the register address. Shift the offset early so the code works mostly unchanged.

2013-08-30ARM: KVM: vgic: simplify vgic_get_target_regMarc Zyngier
vgic_get_target_reg is quite complicated, for no good reason. Actually, it is fairly easy to write it in a much more efficient way by using the target CPU array instead of the bitmap. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Gleb Natapov <gleb@redhat.com>

2013-08-30Xen: Fix retry calls into PRIVCMD_MMAPBATCH*.Andres Lagar-Cavilla
When a foreign mapper attempts to map guest frames that are paged out, the mapper receives an ENOENT response and will have to try again while a helper process pages the target frame back in. Gating checks on PRIVCMD_MMAPBATCH* ioctl args were preventing retries of mapping calls. Permit subsequent calls to update a sub-range of the VMA, iff nothing is yet mapped in that range. Since it is now valid to call PRIVCMD_MMAPBATCH* multiple times, only set vma->vm_private_data if the parameters are valid and (if necessary) the pages for the auto_translated_physmap case have been allocated. This prevents subsequent calls from incorrectly entering the 'retry' path when there are no pages allocated etc. Signed-off-by: Andres Lagar-Cavilla <andres@lagarcavilla.org> Signed-off-by: David Vrabel <david.vrabel@citrix.com> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

The default phase can meet most cards' requirement, but it is not the optimal one. In some extreme situation, the rx phase point produced by the following tuning process will drift quite a distance. Before tuning UHS card, this patch will set a more proper initial tx phase point, which is calculated from statistic data, and can achieve a much better tx signal quality.

TI LCD controller version 2 adds some extra bits in a register to increase the available size to represent horizontal timings. This patch allows the fbdev driver to utilize those extra bits. This will become important for driving an HDMI encoder from the lcd controller where some of the VESA/CEA modes require quite large porches.

The LCD controller represents some of the timing fields with a 0 in the register representing 1. This was not taken into account when these registers were being set.

2013-08-30gpio: add GPIO support for F71882FG and F71889FSimon Guinot
This patch adds support for the GPIOs found on the Fintek super-I/O chips F71882FG and F71889F. A super-I/O is a legacy I/O controller embedded on x86 motherboards. It is used to connect the low-bandwidth devices. Among others functions the F71882FG/F71889F provides: a parallel port, two serial ports, a keyboard controller, an hardware monitoring controller and some GPIO pins. Note that this super-I/Os are embedded on some Atom-based LaCie NASes. The GPIOs are used to control the LEDs and the hard drive power. Changes since v3: - Use request_muxed_region to protect the I/O ports against concurrent accesses. Changes since v2: - Remove useless NULL setters for driver data. Changes since v1: - Enhance the commit message by describing what is a Super-I/O. - Use self-explanatory names for the GPIO register macros. - Add a comment to explain the platform device and driver registration. - Fix gpio_get when GPIO is configured in input mode. I only had the hardware to check this mode recently... Signed-off-by: Simon Guinot <simon.guinot@sequanux.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2013-08-30OMAPDSS: rename omap_dss_device's 'device' field to 'dst'Tomi Valkeinen
In the old panel device model we had omap_dss_output entities, representing the encoders in the DSS block. This entity had "device" field, which pointed to the panel that was using the omap_dss_output. With the new panel device model, the omap_dss_output is integrated into omap_dss_device, which now represents a "display entity". Thus the "device" field, now in omap_dss_device, points to the next entity in the display entity-chain.
