Hi,
This is (a much delayed, sorry!) PATCHv2 of the EXC80Hxx support patchset. Here is the changelog since [PATCHv1]:
- prepend new patch converting binding document to YAML - prepend new patch switching to I2C probe_new - append new patch adding reset-gpio support - use explicit compatible values for the touchscreen chips instead of a wildcast. Since the documentation, that I have is very vague let's use different values for exc80h60 and exc80h84. This avoids wildcard DT entries and means we are prepared when noticing differences between the chips. - add accidently removed terminator entry in exc3000_id - use device structure with max_xy and name (suggested by Martin) - use SZ_4K, SZ_16K defines (suggested by Dmitry) - harden event check, so that MT1 and MT2 based chips only allow their own event type. - write more detailed commit description in the fw_version/model sysfs patch to explain why the values are not cached and why the simpler read(); sleep(); write() approach has not been used - use DEVICE_ATTR_RO() in fw_version/model patch to improve readability - fw_version/model: replace memcpy + null termination with strlcpy - fw_version/model: increase buffer size for weird firmware versions - fw_version/model: use sizeof() instead of hardcoded buffer sizes - simplify exc3000_query_interrupt() by moving the complete() call to the exc3000_interrupt().
I think I only ignored one review feedback, that the fw_version and model sysfs nodes are attached to the input device instead of the i2c device. This was done to avoid being racy:

Properties look like this after applying the patchset:
$ cat /sys/class/input/input1/{name,fw_version,model} EETI EXC80H60 Touch Screen 00_T6 Orion_1320
Thanks in advance for looking at the patches,
