 /* Helper functions for reading the keyboard matrix
- * Note: We should really be using pxa_gpio_mode to alter GPDR but it
- *       requires a function call per GPIO bit which is excessive
- *       when we need to access 11 bits at once, multiple times.

  * These functions must be called within local_irq_save()/local_irq_restore()
  * or similar.
