[PATCH v4 12/26] ARM: pxa: magician: Rename charger cable detection EGPIOs

From: Petr Cvek
Date: Mon Sep 28 2015 - 17:32:43 EST


This patch renames EGPIOs, which are used for the charging cable presence
and type detection. Old names did not correspond with an observed
functionality (on board_id 0x3a). The behavior is not:

- AC charger
- USB charger
- Cable detection

, but:

- AC/USB type
- Cable detection1
- Cable detection2

This patch fixes a possible typo in the bit offset for the cable detection
EGPIO declaration, too.
