i9195: add initial support

Merged Imported i9195: add initial support
rrooij:device-samsung-i9195 into master
Merged Imported Administrator requested to merge rrooij:device-samsung-i9195 into master

Created by: rrooij

Current status:

  • Red glare on screen (probably need kernel patch)
  • No touch support
  • Networking on USB with SSH does not work, but the device boots normally and does not freeze, so this is probably just a kernel config that needs to be set

    @rrooij Try disabling CONFIG_USB_ANDROID_SAMSUNG_COMPOSITE: it looks like that disables non-mtp modes in the USB composite driver.

    @zhuowei The kernel fails to compile when CONFIG_USB_ANDROID_SAMSUNG_COMPOSITE is turned off. The kernel does compile when I disable both CONFIG_USB_ANDROID_G and the Samsung Composite option, but it has the same problem with no SSH.

    Using the ethernet USB Gadget driver does not work either.

    Dmesg output with both CONFIG_USB_ANDROID_SAMSUNG_COMPOSITE and CONFIG_USB_ANDROID_G:

    as discussed in chat, the usb issue might be something like this https://github.com/postmarketOS/pmbootstrap/blob/master/aports/device/device-htc-bravo/initfs-hook.sh#L8

    @ollieparanoid It's been added to the device overview and has now a entry on the wiki: https://wiki.postmarketos.org/wiki/Samsung_Galaxy_S4_Mini_LTE

    I already made a patch for the problem when setting other USB gadget drivers, but haven't included it yet, as I was afraid that it might lead to other problems that I can't foresee. It still booted when flashing and choosing the ethernet gadget driver though, but USB didn't work regardless.

    @rrooij The kernel linked on the Wiki page seems to be wrong: you might want to change it to link to android_kernel_samsung_msm8930-common instead.
