- catchup in the 'ifm AC14xx' board's device tree with recently added keypad-matrix driver features: individual pin polarity for rows and columns, push/pull pin operation for columns - slight re-ordering of keypad-matrix related settings, and tuning of timing specs for more reliable detection of short lived key presses (including a range spec to reduce timer management overhead) as well as a slightly increased overall matrix poll frequency - fix keymap comments, make the names match the codes Signed-off-by: Gerhard Sittig <redacted> --- arch/powerpc/boot/dts/ac14xx.dts | 13 +++++++------ 1 file changed, 7 insertions(+), 6 deletions(-)
