[PATCH 01/21 v5] Input: atmel_mxt_ts - derive phys from i2c client adapter
From: Daniel Kurtz <hidden>

Subsystem:
atmel maxtouch driver, input (keyboard, mouse, joystick, touchscreen) drivers, the rest · Maintainers:

This allows userspace to more easily distinguish which bus a particular atmel_mxt_ts device is attached to. The resulting phys will be something like: i2c-1-0067/input0 Signed-off-by: Daniel Kurtz <redacted> --- drivers/input/touchscreen/atmel_mxt_ts.c | 5 +++++ 1 files changed, 5 insertions(+), 0 deletions(-)
