* ARM: EXYNOS: switch to using generic cpufreq driver for exynos4x12Bartlomiej Zolnierkiewicz2015-08-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new CPU clock type allows the use of generic CPUfreq driver. Switch Exynos4x12 to using generic cpufreq driver. Previously (when exynos-cpufreq driver was used with boost functionality) ARM_EXYNOS_CPU_FREQ_BOOST_SW config option (which enabled boost functionality) selected EXYNOS_THERMAL one. After switching Exynos4x12 platforms to use cpufreq-dt driver boost support is enabled in the cpufreq-dt driver itself (because there are turbo OPPs defined in the board's DTS file). However we still would like to allow enabling boost support only if thermal support is also enabled for Exynos platforms. To achieve this make ARCH_EXYNOS config option select THERMAL and EXYNOS_THERMAL ones. Please also note that the switch to use the generic cpufreq-dt driver fixes the minor issue present with the old code (support for 'boost' mode in the exynos-cpufreq driver was enabled for all supported SoCs even though 'boost' frequency was provided only for Exynos4x12 ones).

|/ | | | | | | | | | | | | | | | | | | | | | | | | | The following patch adds coupled cpuidle support for Exynos3250 to an existing cpuidle-exynos driver.

The detailed changelog: - use exynos_[get,set]_boot_addr() in cpuidle-exynos.c and then make cpu_boot_reg_base() static - use exynos_core_restart() in exynos_cpu0_enter_aftr() - add missing smp_rmb() to exynos_cpu0_enter_aftr() (to make the code in-sync with the platform SMP code) - add call_firmware_op(cpu_boot, 1) to exynos_cpu0_enter_aftr() - use dsb_sev() instead of IPI wakeup for Exynos3250 in exynos_cpu0_enter_aftr() - add CPU0 vs CPU1 synchronization based on S5P_PMU_SPARE2 register for Exynos3250 to cpuidle-exynos.c - add flush_cache_all() for CPU1/0 before powerdown/AFTR for Exynos3250 to exynos_wfi_finisher()/exynos_do_idle() Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Cc: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Kukjin Kim <kgene@kernel.org>

* ARM: EXYNOS: Fix failed second suspend on Exynos4Krzysztof Kozlowski2015-05-141-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | 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: exynos4/5: convert pmu wakeup to stacked domainsMarc Zyngier2015-03-181-10/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | Exynos has been (ab)using the gic_arch_extn to provide wakeup from suspend, and it makes a lot of sense to convert this code to use stacked domains instead. This patch does just this, updating the DT files to actually reflect what the HW provides. BIG FAT WARNING: because the DTs were so far lying by not exposing the fact that the PMU block is actually the first interrupt controller in the chain for RTC, kernels with this patch applied wont have any suspend-resume facility when booted with old DTs, and old kernels with updated DTs may not even boot. Also, I strongly suspect that there is more than two wake-up interrupts on these platforms, but I leave it to the maintainers to fix their mess.

* ARM: make arrays containing machine compatible strings constUwe Kleine-König2015-02-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The definition static const char *axxia_dt_match[] __initconst = { ... defines a changable array of constant strings. That is you must not do: *axxia_dt_match[0] = 'k'; but axxia_dt_match[0] = "different string"; is fine. So the annotation __initconst is wrong and yields a compiler error when other really const variables are added with __initconst. As the struct machine_desc member dt_compat is declared as const char *const *dt_compat; making the arrays const is the better alternative over changing all annotations to __initdata.

As a result it enables AFTR mode to be used by default on Exynos4210 without the need to hot unplug CPU1 first. The patch is heavily based on earlier cpuidle-exynos4210 driver from Daniel Lezcano: http://www.spinics.net/lists/linux-samsung-soc/msg28134.html Changes from Daniel's code include: - porting code to current kernels - fixing it to work on my setup (by using S5P_INFORM register instead of S5P_VA_SYSRAM one on Revison 1.1 and retrying poking CPU1 out of the BOOT ROM if necessary) - fixing rare lockup caused by waiting for CPU1 to get stuck in the BOOT ROM (CPU hotplug code in arch/arm/mach-exynos/platsmp.c doesn't require this and works fine) - moving Exynos specific code to arch/arm/mach-exynos/pm.c - using cpu_boot_reg_base() helper instead of BOOT_VECTOR macro - using exynos_cpu_*() helpers instead of accessing registers directly - using arch_send_wakeup_ipi_mask() instead of dsb_sev() (this matches CPU hotplug code in arch/arm/mach-exynos/platsmp.c) - integrating separate exynos4210-cpuidle driver into existing exynos-cpuidle one Cc: Colin Cross <ccross@google.com> Cc: Kukjin Kim <kgene.kim@samsung.com> Cc: Krzysztof Kozlowski <k.kozlowski@samsung.com> Cc: Tomasz Figa <tomasz.figa@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Acked-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Kukjin Kim <kgene@kernel.org>

| * ARM: EXYNOS: Move cpufreq and cpuidle device registration to init_machinePankaj Dubey2014-07-231-14/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | As exynos_cpuidle_init() and exynos_cpufreq_init() functions have just one line of code for registering platform devices. So we can move them to exynos_dt_machine_init() and remove exynos_cpuidle_init() and exynos_cpufreq_init(). This will help in reducing lines of code in exynos.c, making it more clean.

| * ARM: EXYNOS: Refactored code for using PMU address via DTPankaj Dubey2014-07-231-11/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".
