xen, fbfront: fix connecting to backend

2017-04-22T05:14:58+00:00

commit 9121b15b5628b38b4695282dc18c553440e0f79b upstream. Connecting to the backend isn't working reliably in xen-fbfront: in case XenbusStateInitWait of the backend has been missed the backend transition to XenbusStateConnected will trigger the connected state only without doing the actions required when the backend has connected.

fbdev: color map copying bounds checking

2017-04-18T05:55:46+00:00

commit 2dc705a9930b4806250fbf5a76e55266e59389f2 upstream. Copying color maps to userspace doesn't check the value of to->start, which will cause kernel heap buffer OOB read due to signedness wraps.

fbdev: da8xx-fb: fix videomodes of lcd panels

2016-07-12T12:47:52+00:00

[ Upstream commit 713fced8d10fa1c759c8fb6bf9aaa681bae68cad ] Commit 028cd86b794f4a ("video: da8xx-fb: fix the polarities of the hsync/vsync pulse") fixes polarities of HSYNC/VSYNC pulse but forgot to update known_lcd_panels[] which had sync values according to old logic. This breaks LCD at least on DA850 EVM. This patch fixes this issue and I have tested this for panel "Sharp_LK043T1DG01" using DA850 EVM board.

xen kconfig: don't "select INPUT_XEN_KBDDEV_FRONTEND"

2016-07-12T12:47:47+00:00

[ Upstream commit 13aa38e291bdd4e4018f40dd2f75e464814dcbf3 ] The Xen framebuffer driver selects the xen keyboard driver, so the latter will be built-in if XEN_FBDEV_FRONTEND=y. However, when CONFIG_INPUT is a loadable module, this configuration cannot work. On mainline kernels, the symbol will be enabled but not used, while in combination with a patch I have to detect such useless configurations, we get the expected link failure: drivers/input/built-in.o: In function `xenkbd_remove': xen-kbdfront.c:(.text+0x2f0): undefined reference to `input_unregister_device' xen-kbdfront.c:(.text+0x30e): undefined reference to `input_unregister_device' This removes the extra "select", as it just causes more trouble than it helps. In theory, some defconfig file might break if it has XEN_FBDEV_FRONTEND in it but not INPUT_XEN_KBDDEV_FRONTEND. The Kconfig fragment we ship in the kernel (kernel/configs/xen.config) however already enables both, and anyone using an old .config file would keep having both enabled.

fbdev: select versatile helpers for the integrator

2015-10-28T02:13:55+00:00

[ Upstream commit 2701fa0864ecb9e49d47a4aa1c02f172ab79639a ] Commit 11c32d7b6274cb0f554943d65bd4a126c4a86dcd "video: move Versatile CLCD helpers" missed the fact that the Integrator/CP is also using the helper, and as a result the platform got only stubs and no graphics. Add this as a default selection to Kconfig so we have graphics again.

video/fbdev: fix defio's fsync

2015-01-27T16:29:39+00:00

commit 30ea9c5218651bc11cbdba7820be78f04e2d83bc upstream. fb_deferred_io_fsync() returns the value of schedule_delayed_work() as an error code, but schedule_delayed_work() does not return an error. It returns true/false depending on whether the work was already queued. Fix this by ignoring the return value of schedule_delayed_work().

PLL_SELFREQDCO bitfield is from bit 3 to 1, but the driver writes bits from 4 to 1. The bit 4 is 'reserved', so this probably should not cause any issues, but it's better to fix it. Signed-off-by: Tomi Valkeinen
