Subject: [PATCH v3 04/15] spi: dt-bindings: dw-apb-ssi: update spi-{r,t}x-bus-width
Date: Wed, 29 Jun 2022 19:43:33 +0100 [thread overview]
Message-ID: <20220629184343.3438856-5-mail@conchuod.ie> (raw)
In-Reply-To: <20220629184343.3438856-1-mail@conchuod.ie>
From: Conor Dooley <conor.dooley@microchip.com>
Most users of dw-apb-ssi use spi-{r,t}x-bus-width of 1, however the
Canaan k210 is wired up for a width of 4.
Quoting Serge:
The modern DW APB SSI controllers of v.4.* and newer also support the
enhanced SPI Modes too (Dual, Quad and Octal). Since the IP-core
version is auto-detected at run-time there is no way to create a
DT-schema correctly constraining the Rx/Tx SPI bus widths.
/endquote
As such, drop the restriction on only supporting a bus width of 1.
