| | | | | | | | | | | | | | Add basic MSL support for i.MX6SLL. The i.MX 6SoloLiteLite application processors are NXP's latest additions to a growing family of multimedia-focused products offering high-performance processing optimized for lowest power consumption. The i.MX 6SoloLiteLite processors feature NXP's advanced implementation of the ARM Cortex-A9 core, which can be interfaced with LPDDR3 and LPDDR2 DRAM memory devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The rnga platform device is initialized for all imx31 machines from its own initcall, but is never initialized anywhere else. This moves the platform device creation into both the imx31 dt and non-dt machine init sequences, which has basically the exact same effect as before, but makes it more obvious what is going on, while reducing the amount of code and removing the last user of cpu_is_mx31().

When ordering the symbols the following rationale was used: if the selects were in alphabetical order, I moved select GPIOLIB to be in alphabetical order, but if the selects were not maintained in alphabetical order, I just replaced "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

| | | | | | | | | | | | | | | There is no reason to limit the TWD to be used on SMP kernels only if the hardware has it available. On Wandboard i.MX6SOLO, running PREEMPT-RT and cyclictest I see as max immediately after start in idle: UP : ~90us SMP: ~50us UP + TWD: ~20us.

* ARM: imx: select ARM_CPU_SUSPEND only for imx6Arnd Bergmann2016-02-281-1/+1
| | | | | | | | | | | | | | | | | | | | | i.MX only needs to select ARM_CPU_SUSPEND manually for the very specific case that CONFIG_PM_SLEEP is disabled and imx6 is used with CONFIG_PM enabled for runtime PM. If we are building a kernel only for CPUs that are not using the cpu_suspend() helper, we otherwise get a harmless build warning: warning: (ARCH_MXC && SOC_IMX23 && SOC_IMX28 && ARCH_PXA && MACH_MVEBU_V7 && ARCH_OMAP3 && ARCH_OMAP4 && SOC_OMAP5 && SOC_AM33XX && SOC_DRA7XX && ARCH_EXYNOS3 && ARCH_EXYNOS4 && EXYNOS5420_MCPM && EXYNOS_CPU_SUSPEND && ARCH_VEXPRESS_TC2_PM && ARM_BIG_LITTLE_CPUIDLE && ARM_HIGHBANK_CPUIDLE && QCOM_PM) selects ARM_CPU_SUSPEND which has unmet direct dependencies (ARCH_SUSPEND_POSSIBLE) This moves the option to the SOC_IMX6 option that actually requires it, in effect reverting commit f36b594f3754 ("ARM: mach-imx: Select ARM_CPU_SUSPEND at ARCH_MXC level") that was meant as a cleanup and unintentionally caused this warning.

* | ARM: use "depends on" for SoC configs instead of "if" after promptMasahiro Yamada2015-12-011-2/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many ARM sub-architectures use prompts followed by "if" conditional, but it is wrong. Please notice the difference between config ARCH_FOO bool "Foo SoCs" if ARCH_MULTI_V7 and config ARCH_FOO bool "Foo SoCs" depends on ARCH_MULTI_V7 These two are *not* equivalent! In the former statement, it is not ARCH_FOO, but its prompt that depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO is selected by another, but ARCH_MULTI_V7 is still disabled. As it is not unmet dependency, Kconfig never warns. This is probably not what you want. The former should be used only when you need to do so, and you really understand what you are doing. (In most cases, it should be wrong!) For enabling/disabling sub-architectures, the latter is always correct. As a good side effect, this commit fixes some entries over 80 columns (mach-imx, mach-integrator, mach-mbevu).

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows to build the Kernel for Vybrid (VF6xx) SoC when ARMv7-M CPU is selected. The resulting image runs on the secondary Cortex-M4 core. This core has equally access to all peripherals as the main Cortex-A5 core. However, there is no resource control mechanism, hence when both cores are used simultaneously, orthogonal device tree's are required. The boot CPU is dependent on the SoC variant. The available boards use mostly variants where the Cortex-A5 is the primary and hence the boot CPU. Booting the secondary Cortex-M4 CPU needs SoC specific registers written. There is no in kernel support for this right now, a external userspace utility called "m4boot" can be used to boot the kernel: m4boot xipImage initramfs.cpio.lzo vf610m4-colibri.dtb Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When generic pm domain support is enabled, the PGC can be used to completely gate power to the PU power domain containing GPU3D, GPU2D, and VPU cores. This code triggers the PGC powerdown sequence to disable the GPU/VPU isolation cells and gate power and then disables the PU regulator. To reenable, the reverse powerup sequence is triggered after the PU regulator is enabled again. The GPU and VPU devices in the PU power domain temporarily need to be clocked during powerup, so that the reset machinery can work.

* / irqchip: vf610-mscm-ir: Add support for Vybrid MSCM interrupt routerStefan Agner2015-03-081-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for Vybrid's interrupt router. On VF6xx models, almost all peripherals can be used by either of the two CPU's, the Cortex-A5 or the Cortex-M4. The interrupt router routes the peripheral interrupts to the configured CPU. This IRQ chip driver configures the interrupt router to route the requested interrupt to the CPU the kernel is running on. The driver makes use of the irqdomain hierarchy support. The parent is given by the device tree. This should be one of the two possible parents either ARM GIC or the ARM NVIC interrupt controller. The latter is currently not yet supported. Note that there is no resource control mechnism implemented to avoid concurrent access of the same peripheral. The user needs to make sure to use device trees which assign the peripherals orthogonally. However, this driver warns the user in case the interrupt is already configured for the other CPU. This provides a poor man's resource controller.

| | | | | | | | | | | | | The newly introduced LS1021A SoC selects CONFIG_SOC_FSL, which is originally symbol used for the PowerPC based platforms and guards lots of code that does not build on ARM.

This leaves the PIT timer for other users e.g. the secondary Cortex-M4 core. Also, the Global Timer has double the precission (running at pheripheral clock compared to IPG clock) and a 64-bit incrementing counter register. We still keep the PIT timer as an secondary option in case the ARM Global Timer is not available.
