Subject: [PATCH] tpm_tis_spi: use new `delay` structure for SPI transfer delays
Date: Wed, 4 Dec 2019 10:00:49 +0200
Message-ID: <20191204080049.32701-1-alexandru.ardelean@analog.com> (raw)

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_secs`
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 bebcfd272df6485 ("spi: introduce `delay` field for
`spi_transfer` + spi_transfer_delay_exec()")
