Subject: [PATCH v2] input: touchscreen: ad7877: Use new structure for SPI transfer delays
Date: Fri, 28 Feb 2020 12:45:08 +0200	[thread overview]
Message-ID: <20200228104508.15564-1-sergiu.cuciurean@analog.com> (raw)
In-Reply-To: <20200227130619.28142-1-sergiu.cuciurean@analog.com>

In a recent change to the SPI subsystem [1], a new `delay` struct was added
to replace the `delay_usecs`. This change replaces the current
`delay_usecs` with `delay` for this driver.

The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure
that both `delay_usecs` & `delay` are used (in this order to preserve
backwards compatibility).

[1] commit bebcfd272df6 ("spi: introduce `delay` field for
`spi_transfer` + spi_transfer_delay_exec()")
