From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mircea Caprioru Subject: [PATCH V4 1/5] iio: adc: ad7124: Remove input number limitation Date: Tue, 25 Jun 2019 11:11:24 +0300 Message-ID: <20190625081128.22190-1-mircea.caprioru@analog.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-kernel-owner@vger.kernel.org To: jic23@kernel.org Cc: Michael.Hennerich@analog.com, stefan.popa@analog.com, lars@metafoo.de, gregkh@linuxfoundation.org, linux-kernel@vger.kernel.org, linux-iio@vger.kernel.org, devicetree@vger.kernel.org, robh+dt@kernel.org, Mircea Caprioru List-Id: devicetree@vger.kernel.org The driver limits the user to use only 4/8 differential inputs, but this device has the option to use pseudo-differential channels. This will increase the number of channels to be equal with the number of inputs so 8 channels for ad7124-4 and 16 for ad7124-8. This patch removes the check between channel nodes and num_inputs value.
