ARM: samsung: Remove HAVE_S3C2410_I2C and use direct dependencies

2021-11-21T16:46:18Z

A separate Kconfig option HAVE_S3C2410_I2C for Samsung SoCs is not really needed and the i2c-s3c24xx driver can depend on Samsung ARM architectures instead. This also enables i2c-s3c2410 for arm64 Exynos SoCs, which is required for example by Exynos850. This is basically continuation of work made in following commits: - commit d96890fca9fd ("rtc: s3c: remove HAVE_S3C_RTC in favor of direct dependencies") - commit 7dd3cae90d85 ("ARM: samsung: remove HAVE_S3C2410_WATCHDOG and use direct dependencies") Signed-off-by: Sam Protsenko Link: https://lore.kernel.org/r/20211121150558.21801-2-semen.protsenko@linaro.org Signed-off-by: Krzysztof Kozlowski

rtc: s3c: remove HAVE_S3C_RTC in favor of direct dependencies

2021-10-17T17:15:12Z

The config HAVE_S3C_RTC is not really needed since we can simply just add the dependencies directly to RTC_DRV_S3C. Also, one less config to keep track of!

arm: remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL

2020-12-15T20:13:42Z

ARM is the only architecture that defines CONFIG_ARCH_HAS_HOLES_MEMORYMODEL which in turn enables memmap_valid_within() function that is intended to verify existence of struct page associated with a pfn when there are holes in the memory map. However, the ARCH_HAS_HOLES_MEMORYMODEL also enables HAVE_ARCH_PFN_VALID and arch-specific pfn_valid() implementation that also deals with the holes in the memory map. The only two users of memmap_valid_within() call this function after a call to pfn_valid() so the memmap_valid_within() check becomes redundant. Remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL and memmap_valid_within() and rely entirely on ARM's implementation of pfn_valid() that is now enabled unconditionally.

ARM: s5pv210: use private pm save/restore

2020-08-19T19:33:11Z

The pm save/restore code is fairly small, so in order to separate the s3c and s5p platforms, adding an s5p specific copy instead of sharing it is actually easier. Signed-off-by: Arnd Bergmann Link: https://lore.kernel.org/r/20200806182059.2431-17-krzk@kernel.org Signed-off-by: Krzysztof Kozlowski

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

2020-08-19T19:23:46Z

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: samsung: make pm-debug platform independent

2020-08-19T19:10:50Z

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()

2020-08-19T19:10:50Z

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.

ARM: samsung: remove HAVE_S3C2410_WATCHDOG and use direct dependencies

2020-08-19T18:57:35Z

A separate Kconfig option HAVE_S3C2410_WATCHDOG for Samsung SoCs is not really needed and the s3c24xx watchdog driver can depend on Samsung ARM architectures instead. The "HAVE_xxx_WATCHDOG" pattern of dependency is not popular and Samsung platforms are here exceptions. All others just depend on CONFIG_ARCH_xxx. This makes the code slightly smaller without any change in functionality. Signed-off-by: Krzysztof Kozlowski Acked-by: Guenter Roeck

ARM: s5pv210: Remove legacy setting of external wakeup interrupts

2018-11-12T20:19:48Z

Since Exynos/S5Pv210 pin-controller driver is taking care about setting the external wakeup interrupts mask, the legacy code can be removed. Signed-off-by: Krzysztof Kozlowski Cc: Tomasz Figa Cc: Sylwester Nawrocki Acked-by: Tomasz Figa
