2019-10-23ARM: dts: exynos: Rename children of SysRAM node to "sram"Krzysztof Kozlowski
The device node name should reflect generic class of a device so rename the children of SysRAM node to "smp-sram". This will be also in sync with upcoming DT schema. No functional change. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

2019-07-01ARM: dts: exynos: Fix imprecise abort on Mali GPU probe on Exynos4210Marek Szyprowski
The PMU module of Mali400 GPU is optional and it looks that it is not present on Exynos4210, because any access to its registers causes external abort. This patch removes "pmu" interrupt for Exynos4210 SoCs, so the driver will skip the PMU module. This fixes following fault during kernel boot: Unhandled fault: imprecise external abort (0x1406) at 0x00000000 (lima_pmu_init) from [<c059e6f8>] (lima_device_init+0x244/0x5a0) (lima_device_init) from [<c059e40c>] (lima_pdev_probe+0x7c/0xd8) (lima_pdev_probe) from [<c05afcb8>] (platform_drv_probe+0x48/0x9c) (platform_drv_probe) from [<c05ad594>] (really_probe+0x1c4/0x400) (really_probe) from [<c05ad988>] (driver_probe_device+0x78/0x1b8) (driver_probe_device) from [<c05add30>] (device_driver_attach+0x58/0x60) (device_driver_attach) from [<c05ade34>] (__driver_attach+0xfc/0x160) (__driver_attach) from [<c05ab650>] (bus_for_each_dev+0x68/0xb4) (bus_for_each_dev) from [<c05ac734>] (bus_add_driver+0x104/0x20c) (bus_add_driver) from [<c05aece0>] (driver_register+0x78/0x10c) (driver_register) from [<c0103214>] (do_one_initcall+0x8c/0x430) (do_one_initcall) from [<c0f01328>] (kernel_init_freeable+0x3c8/0x4d0) (kernel_init_freeable) from [<c0ac3aa0>] (kernel_init+0x8/0x10c) (kernel_init) from [<c01010b4>] (ret_from_fork+0x14/0x20) The PMU module seems to work fine on Exynos4412 SoCs, so the patch also moves the interrupt definitions to exynos4210.dtsi and exynos4412.dtsi respectively, to keep only the common part in exynos4.dtsi.

2018-11-18ARM: dts: exynos: Add all CPUs in cooling mapsViresh Kumar
Each CPU can (and does) participate in cooling down the system but the DT only captures a handful of them, normally CPU0, in the cooling maps. Things work by chance currently as under normal circumstances its the first CPU of each cluster which is used by the operating systems to probe the cooling devices. But as soon as this CPU ordering changes and any other CPU is used to bring up the cooling device, we will start seeing failures. Also the DT is rather incomplete when we list only one CPU in the cooling maps, as the hardware doesn't have any such limitations. Update cooling maps to include all devices affected by individual trip points. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
2018-06-25arm: dts: exynos: Add missing cooling device properties for CPUsViresh Kumar
The cooling device properties, like "#cooling-cells" and "dynamic-power-coefficient", should either be present for all the CPUs of a cluster or none. If these are present only for a subset of CPUs of a cluster then things will start falling apart as soon as the CPUs are brought online in a different order. For example, this will happen because the operating system looks for such properties in the CPU node it is trying to bring up, so that it can register a cooling device. Add such missing properties. Fix other missing properties (clocks, OPP, clock latency) as well to make it all work. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

The Exynos4412 has the same watchdog as newer SoCs (e.g. Exynos5250). Just like the others, for working it requires additional steps in Power Management Unit: unmasking the reset request and enabling the system reset. Without these additional steps in PMU, the watchdog will not be able to reset the system on expiration event. Change the compatible of Exynos4412 watchdog device node to samsung,exynos5250-wdt which includes the additional PMU steps. This will also fix infinite watchdog interrupt in soft mode (lack of interrupt clear) because it is also included in samsung,exynos5250-wdt.

Recent patch by Tomasz Figa ("irqchip: gic: Fix core ID calculation when topology is read from DT") fixed GIC driver to filter cluster ID from values returned by cpu_logical_map() for SoCs having registers mapped without per-CPU banking making it is possible to add CPU nodes for Exynos4 SoCs. In case of Exynos SoCs these CPU nodes are also required by future changes adding initialization of cpuidle states in Exynos cpuidle driver through DT. Tested on Origen board (Exynos4210 SoC) and Trats2 (Exynos4412 SoC). Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device-tree changes from Olof Johansson: "Unlike the board branch, this keeps having large sets of changes for every release, but that's quite expected and is so far working well. Most of this is plumbing for various device bindings and new platforms, but there's also a bit of cleanup and code removal for things that are moved from platform code to DT contents (some OMAP clock code in particular). There's also a pinctrl driver for tegra here (appropriately acked), that's introduced this way to make it more bisectable. I'm happy to say that there were no conflicts at all with this branch this release, which means that changes are flowing through our tree as expected instead of merged through driver maintainers (or at least not done with conflicts). There are several new boards added, and a couple of SoCs. In no particular order: - Rockchip RK3288 SoC support, including DTS for a dev board that they have seeded with some community developers. - Better support for Hardkernel Exynos4-based ODROID boards. - CCF conversions (and dtsi contents) for several Renesas platforms. - Gumstix Pepper (TI AM335x) board support - TI eval board support for AM437x - Allwinner A23 SoC, very similar to existing ones which mostly has resulted in DT changes for support. Also includes support for an Ippo tablet with the chipset. - Allwinner A31 Hummingbird board support, not to be confused with the SolidRun i.MX-based Hummingboard. - Tegra30 Apalis board support" * tag 'dt-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (334 commits) ARM: dts: Enable USB host0 (EHCI) on rk3288-evb ARM: dts: add rk3288 ehci usb devices ARM: dts: Turn on USB host vbus on rk3288-evb ARM: tegra: apalis t30: fix device tree compatible node ARM: tegra: paz00: Fix some indentation inconsistencies ARM: zynq: DT: Clarify Xilinx Zynq platform ARM: dts: rockchip: add watchdog node ARM: dts: rockchip: remove pinctrl setting from radxarock uart2 ARM: dts: Add missing pinctrl for uart0/1 for exynos3250 ARM: dts: Remove duplicate 'interrput-parent' property for exynos3250 ARM: dts: Add TMU dt node to monitor the temperature for exynos3250 ARM: dts: Specify MAX77686 pmic interrupt for exynos5250-smdk5250 ARM: dts: cypress,cyapa trackpad is exynos5250-Snow only ARM: dts: max77686 is exynos5250-snow only ARM: zynq: DT: Remove DMA from board DTs ARM: zynq: DT: Add CAN node ARM: EXYNOS: Add exynos5260 PMU compatible string to DT match table ARM: dts: Add PMU DT node for exynos5260 SoC ARM: EXYNOS: Add support for Exynos5410 PMU ARM: dts: Add PMU to exynos5410 ...

This patch extends nodes of PMU system controller on Exynos4210, 4x12, 5250 and 5420 SoCs with newly defined properties used by Exynos CLKOUT driver. Signed-off-by: Tomasz Figa <t.figa@samsung.com>
2014-07-19ARM: dts: clean up arm-pmu node for exynos4Chanho Park
This patch cleans a arm-pmu node up for exynos4. Only exynos4412 series boards have four pmu interrupts. Rest of exynos4 boards, except 4412, have only two pmu interrupts. Thus, we can define two interrupts in the exynos4.dtsi and extends the interrupts only exynos4412.dtsi.

2014-05-15ARM: EXYNOS: Map SYSRAM through generic DT bindingsSachin Kamat
Instead of hardcoding the SYSRAM details for each SoC, pass this information through device tree (DT) and make the code SoC agnostic. Generic DT SRAM bindings are used for achieving this.
