Subject: [PATCH 3/6] spi: dt-bindings: spi-controller: explicitly require #address-cells=<0> for slave mode
Date: Wed, 14 Oct 2020 00:08:42 +0800 [thread overview]
Message-ID: <20201013160845.1772-4-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <20201013160845.1772-1-thunder.leizhen@huawei.com>
scripts/dtc/checks.c:
if (get_property(node, "spi-slave"))
spi_addr_cells = 0;
if (node_addr_cells(node) != spi_addr_cells)
FAIL(c, dti, node, "incorrect #address-cells for SPI bus");
if (node_size_cells(node) != 0)
FAIL(c, dti, node, "incorrect #size-cells for SPI bus");
The above code in check_spi_bus_bridge() require that the number of address
cells must be 0. So we should explicitly declare "#address-cells = <0>".
