2022-01-24spi: s3c64xx: Convert to use GPIO descriptorsLinus Walleij
Convert the S3C64xx SPI host to use GPIO descriptors. Provide GPIO descriptor tables for the one user with CS 0 and 1.

2022-01-24spi: s3c64xx: Drop custom gpio setup argumentLinus Walleij
The SPI0 platform population function was taking a custom gpio setup callback but the only user pass NULL as argument so drop this argument.

2020-08-28ARM: s3c: Avoid naming clash of S3C24xx and S3C64xx timer setupKrzysztof Kozlowski
PWM timer initialization has two independent implementations - one for S3C24xx and one for S3C64xx. The naming however was always the same and before also the declaration was shared. This is confusing, error prone and might cause issues when trying to build multiplatform kernel.

2020-08-22ARM: s3c: make headers local if possibleArnd Bergmann
A lot of header files are only used internally now, so they can be moved to mach-s3c, out of the visibility of drivers.

2020-08-20ARM: s3c: move into a common directoryArnd Bergmann
s3c24xx and s3c64xx have a lot in common, but are split across three separate directories, which makes the interaction of the header files more complicated than necessary. Move all three directories into a new mach-s3c, with a minimal set of changes to each file.
