+This patch adds support for Sharp CE-RH2 on Spitz.
+
+It is not clean enough to be upstreamed:
+- It is a bit syslog-noisy.
+- Does not support other Zaurus models.
+- Maybe split to more parts:
+  * MAX1111 driver
+  * linear input device
+  * virtual keyboard on top of linear input device
+

+This patch adds support for Sharp CE-RH2 on Akita and CE-RH1 on C7x0.
+
+This patch is a bit ugly:
+- Device specific functions should be moved to platform infrastructure.
+- Maybe define generic *_scoopexp functions handling Akita x Spitz differences.
