"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/).

ARM: EXYNOS: Fix failed second suspend on Exynos4 On Exynos4412 boards (Trats2, Odroid U3) after enabling L2 cache in 56b60b8bce4a ("ARM: 8265/1: dts: exynos4: Add nodes for L2 cache controller") the second suspend to RAM failed. First suspend worked fine but the next one hang just after powering down of secondary CPUs (system consumed energy as it would be running but was not responsive). The issue was caused by enabling delayed reset assertion for CPU0 just after issuing power down of cores. This was introduced for Exynos4 in 13cfa6c4f7fa ("ARM: EXYNOS: Fix CPU idle clock down after CPU off"). The whole behavior is not well documented but after checking with vendor code this should be done like this (on Exynos4): 1. Enable delayed reset assertion when system is running (for all CPUs). 2. Disable delayed reset assertion before suspending the system. This can be done after powering off secondary CPUs. 3. Re-enable the delayed reset assertion when system is resumed.

ARM: EXYNOS: Move code from hotplug.c to platsmp.c Cleanup a little the SMP/hotplug code for Exynos by: 1. Moving completely all functions from hotplug.c into the platsmp.c; 2. Deleting the hotplug.c file. After recent cleanups (e.g. 75ad2ab28f0f "ARM: EXYNOS: use v7_exit_coherency_flush macro for cache disabling") there was only CPU power down related code in hotplug.c file. Rationale behind the code movement and benefits: 1. The file platsmp.c is the only user of code located in hotplug.c. Keeping code in hotplug.c required declaring exynos_cpu_die() in common.h. Such dependencies and mentioned exynos_cpu_die() declaration can be removed. 2. In next patches exynos_set_delayed_reset_assertion() will be introduced. This function will be called by: - cpu_leave_power (hotplug.c), - platform_do_lowpower (hotplug.c), - exynos_boot_secondary (platsmp.c). Merging hotplug.c into platsmp.c leads to simpler and cleaner code with less dependencies between files. The commit only moves code around with one additional observable change: the hotplug.c was compiled with custom CFLAGS (-march=armv7-a). These CFLAGS are not necessary any more.

ARM: EXYNOS: Refactored code for using PMU address via DT Under "arm/mach-exynos" many files are using PMU register offsets. Since we have added support for accessing PMU base address via DT, now we can remove PMU mapping from exynosX_iodesc. Let's convert all these access using iomapped address. This will help us in removing static mapping of PMU base address as well as help in reducing dependency over machine header files. Thus helping for migration of PMU implementation from machine to driver folder which can be reused for ARM64 based SoC. Also as we have removed static mappings from "regs-pmu.h" it does not need map.h anymore. But "platsmp.c" needed this and till now it got included indirectly. So lets move header inclusion of "mach/map.h" from "regs-pmu.h" to "platsmp.c".

ARM: EXYNOS: Fix kernel panic when unplugging CPU1 on exynos A look at the code reveals use of S5P_VA_SYSRAM macro, in case of certain SoC revisions, which is not valid any longer, after SYSRAM started to be mapped dynamically. The new dynamic mapping is stored in sysram_base_addr variable, which is declared static in platsmp.c This fix makes sysram_base_addr non-static, declared it in common.h and used in pm.c instead of S5P_VA_SYSRAM.

ARM: 7257/1: EXYNOS: introduce arch/arm/mach-exynos/common.[ch] This patch introduces common.[ch] which are used only in the arch/arm/mach-exynos/ directory. The common.c file merges the cpu.c, init.c, irq-combiner.c and irq-eint.c files which are used commonly on EXYNOS SoCs and the common.h file replaces with plat/exynos4.h file.
