spi: s3c64xx: fix all kernel-doc warnings

2026-05-07T01:18:48+00:00

Add kernel-doc for one struct member and use the correct function name to eliminate kernel-doc warnings: Warning: include/linux/platform_data/spi-s3c64xx.h:40 struct member 'polling' not described in 's3c64xx_spi_info' Warning: include/linux/platform_data/spi-s3c64xx.h:51 expecting prototype for s3c64xx_spi_set_platdata(). Prototype was for s3c64xx_spi0_set_platdata() instead Signed-off-by: Randy Dunlap Reviewed-by: Krzysztof Kozlowski Reviewed-by: Tudor Ambarus Link: https://patch.msgid.link/20260506175144.449364-1-rdunlap@infradead.org Signed-off-by: Mark Brown

spi: s3c64xx: change polling mode to optional

2023-05-08T00:10:50+00:00

Previously, Polling mode was supported as quirk for SOC without DMA. To provide more flexible support for polling mode, it changed to polling mode when the 'dmas' property is not present in the devicetree, rather than using a quirk. Signed-off-by: Jaewon Kim

spi: s3c64xx: Convert to use GPIO descriptors

2022-01-24T13:37:33+00:00

Convert the S3C64xx SPI host to use GPIO descriptors. Provide GPIO descriptor tables for the one user with CS 0 and 1.

spi: s3c64xx: Drop custom gpio setup argument

2022-01-24T13:37:32+00:00

The SPI0 platform population function was taking a custom gpio setup callback but the only user pass NULL as argument so drop this argument.

spi: s3c64xx: Delete unused boardfile helpers

2022-01-24T13:37:31+00:00

The helpers to use SPI host 1 and 2 are unused in the kernel and taking up space and maintenance hours. New systems should use device tree and not this, so delete the code.

spi: s3c64xx: consider the case when the CS line is not connected

2016-06-29T21:45:23+00:00

When the CS line is not connected, it is not needed to enable or disable the chip selection functionality from the s3c64xx devices in order to perform a transfer. Set the CS controller logically always enabled already during initialization (by writing '0' in the S3C64XX_SPI_SLAVE_SEL register) and never disable it.

spi: s3c64xx: pass DMA arguments in platform data

2015-11-18T17:52:38+00:00

The s3c64xx platform data already contains a pointer to the DMA filter function, but not to the associated data. This simplifies the code and makes it more generic by passing the data along with the filter function like we do for other drivers. Signed-off-by: Arnd Bergmann Signed-off-by: Mark Brown
