From a9d672998a33e4bccdf62f6c2f8a47d51893b83f Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Mon, 14 Mar 2022 21:08:44 -0700 Subject: HID: google: Add support for vivaldi to hid-hammer Add support to the hammer driver to parse vivaldi keyboard layouts and expose them to userspace. This allows hammer devices to use vivaldi function row keys while also supporting the other features this driver supports, like the CBAS (chrome base attached switch) and a keyboard backlight.
