2020-08-19ARM: exynos: use private samsung_cpu_id copyArnd Bergmann1-18/+0
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.

2020-01-07ARM: samsung: Rename Samsung and Exynos to lowercaseKrzysztof Kozlowski1-1/+1
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/).

2014-07-23ARM: EXYNOS: Refactored code for using PMU address via DTPankaj Dubey1-3/+0
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".

The design implies accessing functions and global variables defined in particular mach- subdirectory from common code in plat-, which is not allowed when building ARCH_MULTIPLATFORM. In addition there is a lot of forced code unification, which makes common function handle any possible quirks of all supported SoCs. In the end this design turned out to not work too well, ending with a lot of empty functions exported from mach-, just because code in common pm.c calls them. Moreover, recent trend of moving lower level suspend/resume code to proper drivers, like pinctrl or clk, made a lot of code there redundant, especially on DT-only platforms like Exynos.

next/cleanup This cleanup series gets rid of <mach/timex.h> for platforms not using ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since 387798b (ARM: initial multiplatform support).) To make this work some code out of arch/arm needed to be adapted. The respective changes got acks by their maintainers to be taken via armsoc (with Andrew Morton substituting for Alessandro Zummo as rtc maintainer). Compared to the previous pull request there was another patch added that fixes a (non-critical) regression on ixp4xx.

2013-06-18ARM: EXYNOS: Remove unused base addresses from mach/map.h headerTomasz Figa1-214/+0
This patch removes all the unused base addresses from mach/map.h header, leaving only addresses of IPs that currently use static IO mapping or need the address hardcoded, like low level debug UART.

2013-06-18ARM: EXYNOS: Remove mach/irqs.h headerTomasz Figa1-476/+0
Since Exynos now uses CONFIG_SPARSE_IRQ and all remaining users of this header has been fixed, we can safely remove it.

2013-06-18ARM: EXYNOS: Select SPARSE_IRQ for ExynosTomasz Figa1-0/+1
This patch adds selection of CONFIG_SPARSE_IRQ for ARCH_EXYNOS, since it is required by multiplatform and allows to remove the legacy mach/irqs.h header. To make this possible, a dummy IRQ_EINT_BIT macro is added to pm-core.h header to allow plat-samsung/pm.c compile. This macro is irrelevant for Exynos and will be removed after reworking Samsung pm code for multiplatform compatibility.

2013-05-27ARM: EXYNOS: Fix EINT wake-up mask configuration when pinctrl is usedTomasz Figa1-1/+13
On DT-enabled systems pinctrl-exynos driver is responsible for handling of wake-up EINT interrupts. This patch adjusts wake-up mask configuration code to take wake-up mask value from pinctrl-exynos driver on DT-enabled systems.

2013-05-10ARM: EXYNOS5: Fix kernel dump in AFTR idle modeInderpal Singh1-0/+1
The kernel crashes while resuming from AFTR idle mode. It happens because L2 cache was not going into retention state. This patch configures the USE_RETENTION bit of ARM_L2_OPTION register so that it does not depend on MANUAL_L2RSTDISABLE_CONTROL of ARM_COMMON_OPTION register for L2RSTDISABLE signal.
