Subject: [PATCH] ARM: dts: mx6: Disable the keypad in the dtsi files
Date: Tue, 24 Jun 2014 21:13:44 -0300 [thread overview]
Message-ID: <1403655224-25624-1-git-send-email-festevam@gmail.com> (raw)
From: Fabio Estevam <fabio.estevam@freescale.com>
When booting a board that does not have a keypad (such as imx6q-sabresd) the
following error is seen on boot:
imx-keypad 20b8000.kpp: OF: linux,keymap property not defined in /soc/aips-bus at 02000000/kpp at 020b8000
imx-keypad 20b8000.kpp: failed to build keymap
imx-keypad: probe of 20b8000.kpp failed with error -2
Let's disable the keypad functionality in the dtsi files and let each board dts
enable it when needed.
