Subject: [PATCH 0/3] Input/omap1: fix touchscreen functionality on Nokia 770

Hi all,

This series restores the ads7846 touchscreen functionality on Nokia 770
(and maybe on some other older boards using half-duplex SPI). While the
performance might not be optimal, it's again possible to control the device
using the screen, for testing/development purposes at least.

A.

Aaro Koskinen (3):
  fbdev: omap: use threaded IRQ for LCD DMA
  Input: ads7846 - fix up the pendown GPIO setup on Nokia 770
  Input: ads7846 - restore half-duplex support
