I thought we never shipped 0x150500, but obviously I was wrong.
In current version of Elantech driver, the hw_version detection is done
in elantech_set_properties(), and it's done this way:
int ver = (etd->fw_version & 0x0f0000) >> 16;
if (etd->fw_version < 0x020030 || etd->fw_version == 0x020600)
etd->hw_version = 1;
else if (etd->fw_version < 0x150600)
etd->hw_version = 2;
else if (ver == 5)
etd->hw_version = 3;
else if (ver == 6)
etd->hw_version = 4;
else
return -1;
This "ver" integer really means the version of the IC body, and the
magic number 0x150600 is from an old version of our internal driver
maintained by Tom Lin <tom_lin@emc.com.tw> (also CCed). Your touchpad
seems to be a v3 hardware, but due to the fw_version(0x150500) less then
the magic number, it's treated as a v2 by driver.
For now, could you please try the below patch? I think I will have to do
some history homework and ask our senior firmware guys to come up with
a correct patch.
Thanks,
jj
