Subject: [PATCH v3 00/12] spi: s3c64xx: remove OF alias ID dependency
Date: Fri, 16 Feb 2024 07:05:43 +0000 [thread overview]
Message-ID: <20240216070555.2483977-1-tudor.ambarus@linaro.org> (raw)
The driver was wrong as it assumed that the alias values in devicetree
have a particular meaning in identifying instances. This immediately
breaks when there is a dtb file that does not use the same alias values,
e.g. because it only needs some of the SPI ports.
Tested gs101 SPI with spi-loopback-test, all went fine. I updated
exynos850 as it uses the same USI.SPI_VERSION as gs101. Maybe Sam can
test exynos850, if not, we can drop that patch (12/12).
v3:
- fix indentation in dt-bindings
- collect Rob's R-b
v2:
- update bindings to consider the asymmetric case where the RX FIFO
depth can differ from the TX FIFO depth
- update commit message in patch 11/12 to describe the GS101 change
(I was wrongly mentioning exynos 850).
Tudor Ambarus (12):
spi: dt-bindings: introduce FIFO depth properties
spi: s3c64xx: define a magic value
spi: s3c64xx: allow full FIFO masks
spi: s3c64xx: determine the fifo depth only once
spi: s3c64xx: retrieve the FIFO depth from the device tree
spi: s3c64xx: allow FIFO depth to be determined from the compatible
spi: s3c64xx: let the SPI core determine the bus number
spi: s3c64xx: introduce s3c64xx_spi_set_port_id()
spi: s3c64xx: get rid of the OF alias ID dependency
spi: s3c64xx: deprecate fifo_lvl_mask, rx_lvl_offset and port_id
spi: s3c64xx: switch gs101 to new port config data
spi: s3c64xx: switch exynos850 to new port config data
