I've been unable to get the touchscreen on my Teclast X98 Plus II tablet working. I extracted the firmware from the supplied Windows driver using scanwindrv. [alex@linux ~]$ dmesg | grep silead_ts [ 20.717377] silead_ts i2c-MSSL1680:00: i2c-MSSL1680:00 supply vddio not found, using dummy regulator [ 20.717718] silead_ts i2c-MSSL1680:00: i2c-MSSL1680:00 supply avdd not found, using dummy regulator [ 20.718730] silead_ts i2c-MSSL1680:00: Silead chip ID: 0x80360000 [ 20.726408] silead_ts i2c-MSSL1680:00: Registers clear error -11 [ 20.856162] silead_ts: probe of i2c-MSSL1680:00 failed with error -11 I tried several kernel versions between 4.13 and 4.18. After some online research I realized this issue occured on Cherry Trail devices before but suggested patches havent been applied as it seems. https://patchwork.kernel.org/patch/9531463/ Any news on this issue?
