This patch adds s3c_fb_driverdata s3c_fb_data_exynos5 for EXYNOS5 and adds extended timing control setting. EXYNOS5 FIMD needs extended setting for video timing control. Additional bits are added to VIDTCON2, VIDWxxADD2, VIDOSDxA and VIDOSDxB registers in order to set timing value for lager resolution. Also, address offset of VIDTCONx registers is changed from 0x0 to 0x20000, thus variable type should be changed to int type to handle the address offset of VIDTCONx registers for EXYNOS5 FIMD.

2012-03-04udlfb: Add module_param to allow forcing pixel_limitBen Collins1-0/+12
Some user scenarios need to prioritize performance over maxiumum resolution. Also, some devices may have bad vendor descriptors, and this allows the user to set a pixel limit that matches their specific device to avoid blank screens on higher resolution monitors. 700000 minimum for DL-115, 2360000 maximum for DL-195 Signed-off-by: Ben Collins <bcollins@ubuntu.com> Signed-off-by: Bernie Thompson <bernie@plugable.com>
2012-03-04udlfb: Make sure to get correct endian keys from vendor descriptorBen Collins1-1/+1
The driver was not using le16_to_cpu when reading keys from the vendor descriptor, causing incorrect parsing. Mainly, sku_pixel_limit was not being parsed on big-endian systems. This would result in a blank screen on big-endian CPUs where the DL chips's max mode was smaller than the monitor's native mode.

2012-03-03hwmon: (f75375s) Catch some attempts to write to r/o registersNikolaus Schulz1-0/+27
It makes no sense to attempt to manually configure the fan in auto mode, or set the duty cycle directly in closed loop mode. The corresponding registers are then read-only. If the user tries it nonetheless, error out with EINVAL instead of silently doing nothing.

2012-03-02hwmon: (f75375s) Properly map the F75387 automatic modes to pwm_enableNikolaus Schulz1-8/+34
The F75387 supports automatic fan control using either PWM duty cycle or RPM speed values. Make the driver detect the latter mode, and expose the different modes in sysfs as per pwm_enable, so that the user can switch between them. The interpretation of the pwm_enable attribute for the F75387 is adjusted to be a superset of those values used for similar Fintek chips which do not support automatic duty mode, with 2 mapping to automatic speed mode, and moving automatic duty mode to the new value 4. Toggling the duty mode via pwm_enable is currently denied for the F75387, as the chip then simply reinterprets the fan configuration register values according to the new mode, switching between RPM and PWM units, which makes this a dangerous operation. This patch introduces a new pwm mode into the driver. This is necessary because the new mode (automatic pwm mode, 4) may already be enabled by the BIOS, and the driver should not break existing functionality. This was seen on at least one board.

2012-03-02udlfb: fix hcd_buffer_free panic on unplug/replugBernie Thompson1-66/+80
Fix race conditions with unplug/replug behavior, in particular take care not to hold up USB probe/disconnect for long-running framebuffer operations and rely on usb to handle teardown. Fix for kernel panic reported with new F17 multiseat support. Reported-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Bernie Thompson <bernie@plugable.com>

2012-03-01virtio: balloon: leak / fill balloon across S4Amit Shah1-11/+22
commit e562966dbaf49e7804097cd991e5d3a8934fc148 added support for S4 to the balloon driver. The freeze function did nothing to free the pages, since reclaiming the pages from the host to immediately give them back (if S4 was successful) seemed wasteful. Also, if S4 wasn't successful, the guest would have to re-fill the balloon. On restore, the pages were supposed to be marked freed and the free page counters were incremented to reflect the balloon was totally deflated. However, this wasn't done right. The pages that were earlier taken away from the guest during a balloon inflation operation were just shown as used pages after a successful restore from S4. Just a fancy way of leaking lots of memory. Instead of trying that, just leak the balloon on freeze and fill it on restore/thaw paths. This works properly now. The optimisation to not leak can be added later on after a bit of refactoring of the code. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2012-03-01OMAPDSS: APPLY: make ovl_enable/disable synchronousTomi Valkeinen1-0/+6
ovl->enable/disable are meant to be synchronous so that they can handle the configuration of fifo sizes. The current kernel doesn't configure fifo sizes yet, and so the code doesn't need to block to function (from omapdss driver's perspective). However, for the users of omapdss a non-blocking ovl->disable is confusing, because they don't know when the memory area is not used any more. Furthermore, when the fifo size configuration is added in the next merge window, the change from non-blocking to blocking could cause side effects to the users of omapdss. So by making the functions block already will keep them behaving in the same manner. And, while not the main purpose of this patch, this will also remove the compile warning: drivers/video/omap2/dss/apply.c:350: warning: 'wait_pending_extra_info_updates' defined but not used Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
