Subject: [PATCH v2 0/9] i2c: at91: filters support for at91 SoCs
Date: Tue, 25 Jun 2019 08:04:41 +0000 [thread overview]
Message-ID: <1561449642-26956-1-git-send-email-eugen.hristev@microchip.com> (raw)
From: Eugen Hristev <eugen.hristev@microchip.com>
This series adds the support for i2c filters: analog and digital filter
digital filter is available for sama5d4
an advanced digital filter that allows threshold configuration is available
for sama5d2 and sam9x60
analog filtering is available for sama5d2 and sam9x60
This series also adds platform data for sam9x60 to the driver
In this series version, the enablement of the filters is via Device tree,
as requested by Alexandre Belloni. The PCB/board specific noise is hardware
dependent.
The platform data properties keep the same pattern : set for each SoC
true/false value as it is done for previous properties.
Changes in v2:
- added device tree bindings and support for enable-ana-filt and
enable-dig-filt
- added the new properties to the DT for sama5d4_xplained/sama5d2_xplained
