Subject: [PATCH v3 2/2] ARM: LPC32xx: Make platform use key driver

This patch connects the lpc32xx-key driver to the LPC32xx platform (via
lpc32xx.dtsi), and more specifically to the reference board via its dts file.
The clock.c file needs to be changed to match the automatic device name to its
clock.

Signed-off-by: Roland Stigge <stigge@...com.de>

---
Applies to v3.4-rc4 + LPC32xx DT patches

Please pick this patch for the arm-soc subsystem.

Changes since v2:
* DT: Use "keypad,num-rows", "keypad,num-columns" and "linux,keymap" properties
