Subject: [PATCH v6 0/5] Microchip TCB Capture driver
Date: Mon,  6 Jul 2020 13:43:42 +0200
Message-ID: <20200706114347.174452-1-kamel.bouhara@bootlin.com> (raw)

Hello,

Here is a new counter driver to support Microchip 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 in v6:
 - Rebased on top of v5.8-rc3
 - Added Alexandre's ack
 - Added Rob's ack

Changes in v5:
 - Fix duplicate keys errors in yaml dt-schema

Changes in v4:
 - Use existing binding to document capture mode of the Microchip TCBs.

Changes in v3:
 - Updated the brand name: s/atmel/microchip/.
 - Added missing kernel doc for new elements introduced in structure
   atmel_tcb_config.
 - Removed useless blank line
 - Added an explicit clock removing path using devm_add_action_or_reset

Changes in 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.
 - Fixed errors reported by dt_binding_check
