cpufreq: s3c24xx: move low-level clk reg access into platform code

2020-08-20T15:53:22Z

Rather than have the cpufreq drivers touch include the common headers to get the constants, add a small indirection. This is still not the proper way that would do this through the common clk API, but it lets us kill off the header file usage.

cpufreq: s3c2412: use global s3c2412_cpufreq_setrefresh

2020-08-20T15:52:54Z

There are two identical copies of the s3c2412_cpufreq_setrefresh function: a static one in the cpufreq driver and a global version in iotiming-s3c2412.c. As the function requires the use of a hardcoded register address from a header that we want to not be visible to drivers, just move the existing global function and add a declaration in one of the cpufreq header files.

ARM: s3c: remove cpufreq header dependencies

2020-08-20T15:52:05Z

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.

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

2020-08-19T19:44:11Z

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: samsung: move pm check code to drivers/soc

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

soc: samsung: Rename Samsung and Exynos to lowercase

2020-01-07T19:46:31Z

Fix up inconsistent usage of upper and lowercase letters in "Samsung" and "Exynos" names. "SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked names. Therefore they should be written with lowercase letters starting with capital letter. The lowercase "Exynos" name is promoted by its manufacturer Samsung Electronics Co., Ltd., in advertisement materials and on website. Although advertisement materials usually use uppercase "SAMSUNG", the lowercase version is used in all legal aspects (e.g. on Wikipedia and in privacy/legal statements on https://www.samsung.com/semiconductor/privacy-global/).

pinctrl: samsung: Write external wakeup interrupt mask

2018-07-24T19:56:41Z

The pinctrl driver defines an IRQ chip which handles external wakeup interrupts, therefore from logical point of view, it is the owner of external interrupt mask. The register controlling the mask belongs to Power Management Unit address space so it has to be accessed with PMU syscon regmap handle. This mask should be written to hardware during system suspend. Till now ARMv7 machine code was responsible for this which created a dependency between pin controller driver and arch/arm/mach code. Try to rework this dependency so the pinctrl driver will write external wakeup interrupt mask during late suspend. Impact on ARMv7 designs (S5Pv210 and Exynos) ============================================ This duplicates setting mask with existing machine code arch/arm/mach-exynos/suspend.c and arch/arm/mach-s5pv210/pm.c but it is not a problem - the wakeup mask register will be written twice. The machine code will be cleaned up later. The difference between implementation here and ARMv7 machine code (arch/arm/mach-*) is the time of writing the mask: 1. The machine code is writing the mask quite late during system suspend path, after offlining secondary CPUs and just before doing actual suspend. 2. The implementation in pinctrl driver uses late suspend ops, therefore it will write the mask much earlier. Hopefully late enough, after all drivers will enable or disable their interrupt wakeups (enable_irq_wake() etc). Impact on ARMv8 designs (Exynos5433 and Exynos7) ================================================ The Suspend to RAM was not supported and external wakeup interrupt mask was not written to HW. This change brings us one step closer to supporting Suspend to RAM. Signed-off-by: Krzysztof Kozlowski Cc: Tomasz Figa Cc: Sylwester Nawrocki Acked-by: Tomasz Figa Tested-by: Marek Szyprowski
