ARM: s3c: move into a common directory

2020-08-20T19:00:15+00:00

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.

ARM: s3c: remove cpufreq header dependencies

2020-08-20T15:52:05+00:00

The cpufreq drivers are split between the machine directory and the drivers/cpufreq directory. In order to share header files after we convert s3c to multiplatform, those headers have to live in a different global location. Move them to linux/soc/samsung/ in lack of a better place.

fbdev: s3c2410fb: remove mach header dependency

2020-08-20T15:48:12+00:00

The s3c2410fb driver is too deeply intertwined with the s3c24xx platform code. Change it in a way that avoids the use of platform header files but having all interface data in a platform_data header, and the private register definitions next to the driver itself. One ugly bit here is that the driver pokes directly into gpio registers, which are owned by another driver. Passing the mapped addresses in platform_data is somewhat suboptimal, but it is a small improvement over the previous version.

ARM: s3c: adc: move header to linux/soc/samsung

2020-08-19T19:44:11+00:00

There are multiple drivers using the private adc interface. It seems unlikely that they would ever get converted to iio, so make the current state official by making the header file global. The s3c2410_ts driver needs a couple of register definitions as well.

ARM: s3c24xx: move regs-spi.h into spi driver

2020-08-19T19:40:14+00:00

The file is mostly specific to the driver, the few bits that are actually used by the platform code get moved to mach/map.h instead. Signed-off-by: Arnd Bergmann Acked-by: Mark Brown Link: https://lore.kernel.org/r/20200806182059.2431-20-krzk@kernel.org Signed-off-by: Krzysztof Kozlowski

ARM: samsung: move pm check code to drivers/soc

2020-08-19T19:23:46+00:00

This is the only part of plat-samsung that is really shared between the s3c and s5p ports. Moving it to drivers/soc/ lets us make them completely independent. Signed-off-by: Arnd Bergmann Link: https://lore.kernel.org/r/20200806182059.2431-16-krzk@kernel.org Signed-off-by: Krzysztof Kozlowski

ARM: exynos: use private samsung_cpu_id copy

2020-08-19T19:10:50+00:00

The only part of plat-samsung that is shared with arch-exynos is the CPU identification code. Having a separate exynos_cpu_id variable makes the two completely independent and is actually a bit less code in total.

ARM: samsung: make pm-debug platform independent

2020-08-19T19:10:50+00:00

The pm-debug code is one of the few things shared between s3c24xx/s3c64xx and the newer s5pv210. In order to make s5pv210 independent of plat-samsung, change the common bits of this code to no longer reference the s3c specific bits. In particular, all the CPU checks need to be moved out of the common code into platform specific files.

ARM: samsung: remove s3c_pm_debug_init()

2020-08-19T19:10:50+00:00

On s3c24xx and s3c64xx, this is just a wrapper around s3c_pm_debug_init_uart(), but this function does not exist on s5pv210, which always uses an empty stub as CONFIG_SAMSUNG_ATAGS is normally not set. In a configuration that supports both s5pv210 and s3c64xx, we would always call the s3c64xx function, which is probably incorrect when running on s5pv210. Remove the function call completely on s5pv210 and skip the wrapper on s3c as a cleanup. As a side-effect, the s3c64xx behavior is now always the same, regardless of whether it is a DT-only configuration or both DT and ATAGS are supported for booting.

usb: gadget: s3c: use platform resources

The resources are correctly initialized, so just use them instead of relying on hardcoded data from platform headers. Signed-off-by: Arnd Bergmann Acked-by: Felipe Balbi Link: https://lore.kernel.org/r/20200806182059.2431-8-krzk@kernel.org Signed-off-by: Krzysztof Kozlowski
