* Rebase on 4.11.12 kernel upstream I took the relevant patches from https://git.linaro.org/people/john.stultz/flo.git/log/?h=flo-v4.11 and compiled with upstream kernel.org 4.11.12 kernel. 4.12rc1 and later have not fixed yet problems with freedreno gpu hanging. So we now have an upstream source for the kernel and John Stultz patches separately. Set this to y as it does not seem to have problems in Alpine - CONFIG_HW_RANDOM_MSM=y Enable USB OTG in kernel. I still need to find out how to enable it in Alpine. * Use pkgver instead of hash and other changes * Add dependencies for X11 and osk Added pointercal. Added dependencies so Xfce would work out of the box. Made changes in 90-android-touch-dev.rules as they are needed for proper X11 touchscreen calibration.

of: dma: Make of_dma_deconfigure() public
|
|
As part of moving DMA initializing to probe time the
|
|
of_dma_deconfigure() function will need to be called from different
|
|
source files. Make it public and move it to drivers/of/device.c where
|
|
the of_dma_configure() function is.
