Subject: [PATCH v2 0/3] Atmel TCB capture driver
Date: Thu,  9 Apr 2020 16:13:58 +0200
Message-ID: <20200409141401.321222-1-kamel.bouhara@bootlin.com> (raw)

Hello,

Here is a new counter driver to support Atmel TCB capture devices.

Each SoC has two TCB blocks, each one including three independent
channels.The following series adds support for two counter modes:
increase and quadrature decoder.

As for the atmel clocksource and pwm, the counter driver needs to fill
some tcb capabilities in order to operate with the right configuration.
This is achieved in first patch of this series.

Please feel free to comment.

Cheers,

Changes from v2:
 - Fixed first patch not applying on mainline
 - Updated return code to -EINVAL when user is requesting qdec mode on
   a counter device not supporting it.
 - Added an error case returning -EINVAL when action edge is performed in
   qdec mode.
 - Removed no need to explicity setting ops to NULL from static struct as
   it is the default value.
 - Changed confusing code by using snprintf for the sake of clarity.
 - Changed code to use ARRAY_SIZE so that future reviewers will know
   that num_counts matches what's in the atmel_tc_count array without
   having to check so themselves.
