[ Upstream commit03748d4e00] Currently autoloading for SPI devices does not use the DT ID table, it uses SPI modalises. Supporting OF modalises is going to be difficult if not impractical, an attempt was made but has been reverted, so ensure that module autoloading works for this driver by adding SPI IDs for parts that only have a compatible listed. Fixes:96c8395e21("spi: Revert modalias changes") Signed-off-by: Mark Brown <broonie@kernel.org> Link: https://lore.kernel.org/r/20210927134153.12739-1-broonie@kernel.org Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
