Subject: [PATCHv3 2/5] spi: dt-bindings: support devices with multiple chipselects
Date: Fri, 28 May 2021 13:33:44 +0200 [thread overview]
Message-ID: <20210528113346.37137-3-sebastian.reichel@collabora.com> (raw)
In-Reply-To: <20210528113346.37137-1-sebastian.reichel@collabora.com>
Add binding support for devices, that have more than one
chip select. A typical example are SPI connected microcontroller,
that can also be programmed over SPI like NXP Kinetis or
chips with a configuration and a data chip select, such as
Microchip's MRF89XA transceiver.
