Subject: [PATCH 10/15] Input: atmel_mxt_ts - add bootloader addresses for new chips
Date: Thu, 3 Jul 2014 16:01:32 +0100 [thread overview]
Message-ID: <1404399697-26484-11-git-send-email-nick.dyer@itdev.co.uk> (raw)
In-Reply-To: <1404399697-26484-1-git-send-email-nick.dyer@itdev.co.uk>
From: Nick Dyer <nick.dyer@itdev.co.uk>
Later chips (for example mXT1664S) different mappings for bootloader addresses.
This means that we must look at the family ID to determine which address to
use.
