2015-09-21Input: elan_i2c - expand maximum product_id form 0xFF to 0xFFFFDuson Lin
In order to support more projects in the future, we expand the maximum product_id value form 0xFF to 0xFFFF. Signed-off by: Duson Lin <dusonlin@emc.com.tw> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-06-08Input: elan_i2c - add product IDs FW namesCharlie Mooney
Previously the elan_i2c touchpad driver would simply request the firmware "/lib/firmware/elan_i2c.bin", which does not work well if there are multiple such devices in the system. Let's append the "product ID" (by using the same function as the sysfs interface for consistency) to the filename. This results in filenames of the form "/lib/firmware/elan_i2c_72.0.bin", allowing you to support multiple elan_i2c touchpads on the same device by simply naming each device's FW with its corresponding product ID. This way when you trigger a fw update the driver will load the correct binary. Signed-off-by: Charlie Mooney <charliemooney@chromium.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
