Subject: [PATCH v7 21/48] Input: atmel_mxt_ts - combine bootloader version query with probe
Date: Wed, 12 Feb 2020 00:41:51 -0800 [thread overview]
Message-ID: <20200212084218.32344-22-jiada_wang@mentor.com> (raw)
In-Reply-To: <20200212084218.32344-1-jiada_wang@mentor.com>
From: Nick Dyer <nick.dyer@itdev.co.uk>
This removes some complexity from the bootloader state machine, and means
that we always output some debug about the version as soon as we start
talking to the bootloader.
Signed-off-by: Nick Dyer <nick.dyer@itdev.co.uk>
(cherry picked from ndyer/linux/for-upstream commit a2d141f170c80fea6663af98aab0be32abc0ddb0)
