+Setting keyboard language
+-------------------------
+
+sysfs: keyboard_lang
+
+This feature is used to set keyboard language to ECFW using ASL interface.
+Fewer thinkpads models like T580 , T590 , T15 Gen 1 etc.. has "=", "(',
+")" numeric keys, which are not displaying correctly, when keyboard language
+is other than "english". This is because the default keyboard language in ECFW
+is set as "english". Hence using this sysfs, user can set the correct keyboard
+language to ECFW and then these key's will work correctly.
+
+Example of command to set keyboard language is mentioned below::
+
+        echo jp > /sys/devices/platform/thinkpad_acpi/keyboard_lang
+
+Text corresponding to keyboard layout to be set in sysfs are: be(Belgian),
+cz(Czech), da(Danish), de(
