Subject: [PATCH v3 1/2] spi: dt-bindings: amlogic, meson-gx-spicc: Add pinctrl names for SPI signal states
Date: Wed, 19 Oct 2022 16:01:03 +0200	[thread overview]
Message-ID: <20221004-up-aml-fix-spi-v3-1-89de126fd163@baylibre.com> (raw)
In-Reply-To: <20221004-up-aml-fix-spi-v3-0-89de126fd163@baylibre.com>

SPI pins of the SPICC Controller in Meson-GX needs to be controlled by
pin biais when idle. Therefore define three pinctrl names:
- default: SPI pins are controlled by spi function.
- idle-high: SCLK pin is pulled-up, but MOSI/MISO are still controlled
by spi function.
- idle-low: SCLK pin is pulled-down, but MOSI/MISO are still controlled
by spi function.
