[Qemu-devel] [PATCH 2/2] pxa2xx_keypad: Handle 0xe0xx keycodes |
Date: |
Tue, 15 Feb 2011 15:27:29 +0200 |
Add handling of 0xe0xx keycodes to pxa2xx_driver.
Extended keycodes in keymap should be marked with most significant
bit set (i.e. 0x80). Without this patch it's not possible to handle
i.e. cursor keys.
