samsung-zeroltexx: new device Samsung Galaxy S6 edge (G925F)

This is work to support Samsung Galaxy S6 edge devices (G925F aka zeroltexx). Inspired by some unofficial LineageOS 17.1 port (from https://www.los-legacy.de/17.1/zeroltexx), using the kernel sources from https://github.com/Exynos7420/android_kernel_samsung_exynos7420.

Although there was an earlier report of device support (by Aleksas) on the Wiki page https://wiki.postmarketos.org/wiki/Samsung_Galaxy_S6_Edge_(samsung-zeroltexx) the corresponding port was not available in the repository.

With this port, what works already is:

• Kernel boots
• Display and touch input (tested with Weston and Sxmo)
• USB networking
• Wifi

Firmware files for media (e.g. audio, camera) have not been included, as I wasn't yet able to successfully use these subsystems.

Regarding

Based on some unofficial LineageOS 17.1 port (from https://www.los-legacy.de/17.1/zeroltexx)

Isn't it better to link to the source (github.com/exynos7420) instead of a distribution site?

Are the non-wifi fw files, i.e.

seiren_fw_dram.bin
seiren_fw_sram.bin
fimc_is_fw2.bin
fimc_is_fw2_2p2.bin
fimc_is_fw2_imx240.bin
mfc_fw.bin
setfile_2p2.bin
setfile_4e6.bin
setfile_6b2.bin
setfile_imx240.bin
companion_2p2_master_setfile.bin
companion_2p2_mode_setfile.bin
companion_fw_2p2_evt1.bin
companion_fw_imx240_evt1.bin
companion_imx240_master_setfile.bin
companion_imx240_mode_setfile.bin
ois_fw_dom.bin
ois_fw_sec.bin

necessary to make device boot? Or do you get more things working by adding them (which things in that case)?

Also, nice work! I will give it a try on my 925f during the weekend :)

Looks like the host rndis mac address is set to all zeros, this patch fixes it: https://gitlab.postmarketos.org/postmarketos/pmaports/-/blob/master/device/testing/linux-samsung-a5y17lte/0007-usb_gadget-set-random-rndis-host-MAC-address-to-prev.patch (and makes it less annoying to connect to the device)

I tested the current state again with a fresh rebuild (this time using weston, again), and it seems to work fine as described above (Kernel boots, Display with correct RGB, touch input works, USB networking works (now with MAC automatically set on PC side) as well as Wifi.

Besides the udev rule, this looks good to me. Thanks @st.s!

Side note: ALSA sound works fine if I compile the kernel with gcc6 (similar to MR 346, where this was also necessary due to some "alignment fault"). I'll check if I can make this work with gcc10 too (I'll try to experiment with the kernel compile options). I also had to switch on the speaker output path explicitly with alsactl (actually, I copied a the full configuration from a running Android and used alsactl restore), otherwise the DMA transfer just hangs. Due to some more hacks (firmware in /lib/firmware instead of /lib/firmware/postmarketos etc.) I'd prefer to put this in a followup MR. I'd also create a separate MR for the zerofltexx (G920F) to use the common firmware package (firmware-samsung-zero) and fix WiFi for that device, once this one gets merged.
