[PATCH 0/12] improve pxa27x keypad driver

[PATCH 0/12] improve pxa27x keypad driver

[eric miao]

Most of the code are actually identical to the previous pxa3xx version
I sent to this list month ago. These are separated patches based on
the existing pxa27x_keyboard.c, as requested.

The series of the patches can actually be divided into two groups:
---
      pxa: rename the pxa27x_keyboard to pxa27x_keypad
      pxa: remove the pin configuration from the keypad driver
      pxa: introduce driver structure and use KEY() to define matrix keys
      pxa: introduce pxa27x_keypad_config() for keypad registers configuration
      pxa: enable both rotary encoders and direct keys for keypad
      pxa: use device resources for I/O memory mapping and IRQ
      pxa: add debounce_interval configuration to the keypad platform data
      pxa: make pxa27x_keypad.c support both pxa27x and pxa3xx

---
      pxa: add pxa27x_keypad device and pxa_set_keypad_info()
      pxa: add partial keypad support for mainstone
      pxa: add keypad support for zylonite
      pxa: add keypad support for littleton

I'll send the below 4 patches to RMK's tree if the above 6 are merged.
I'm listing them here for the purpose of completeness and illustration
of the usage.
