From 236d6ac0a1096b6ef833140e57fdfe1fed676bc6 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Fri, 28 Dec 2012 12:25:47 -0200 Subject: ARM: mach-imx: Kconfig: Do not select Babbage for MACH_IMX51_DT When mx51 dt support was added it was necessary to select MACH_MX51_BABBAGE in order to get the mx51 dt built without errors. At that time, there was no pinctrl support for mx51 yet. Currently there is no need to select MACH_MX51_BABBAGE anymore.

This is bad because a SPI board info may declare devices for different SPI buses, and because other code can also call spi_register_board_info() (e.g. a daughter board might provide additional SPI devices). This patch removes the spi_register_board_info() call from da8xx_register_spi(), renames this last one to da8xx_register_spi_bus() to be more explicit, takes the number of chipselect as a function parameter, and updates the impacted board-da8{3,5}0-evm.c, and board-mityomapl138.c files accordingly. It also sets the SPI platform data static, as it doesn't need to be exported.

There is no existing "reset" framework support for SoC devices. The remoteproc driver needs explicit control of the DSP's reset line. To support this, a new DaVinci specific API is added. This private API will disappear with DT migration. Some discussion regarding a proposed DT "reset" binding is here: https://patchwork.kernel.org/patch/1635051/ Modify davinci_clk_init() to set clk "reset" function for clocks that indicate PSC_LRST support. Also fix indentation issue with function opening curly brace.

The sh73a0 IRQ hardware for external IRQ pins consists of the INTCA interrupt controller and the GIC together doing their best to limp along. These external IRQ pins are treated as a special case where interrupts need to be managed in both interrupt controllers in parallel. The ->irq_set_wake() callback for the external IRQ pins can be dealt with in the same way as INTCA-only without involving the GIC. So this patch updates the external IRQ pin code for sh73a0 to no longer involve the GIC.

It is a cleaner approach if every CPU takes care of its own flags. We avoid the need for locking and the program logic is more concise. With this patch the file headsmp-sh73a0.S is added that contains a startup vector for secondary CPUs that sets up its own SCU flags. Further in sh73a0_smp_prepare_cpus() we can rely on the generic ARM helper scu_power_mode(). This is possible as we don't cross borders anymore (every CPU handles its own flags) and need no locking. So we can throw out the needless function modify_scu_cpu_psr().

It does not allow the INTC interrupt controller which is also present on the sh73a0 SoC to be enabled via device tree. Nor does it handle sharing of interrupts between the GIC and INTC interrupt controllers. This limits the usefulness of this code to applications which only wish to access devices which use interrupts that can be handled by the GIC interrupt controller. Other applications should, for now, continue using non-device tree initialisation of the sh72a0 interrupt controllers.

To make Tegra device can compile for UP. It needs to be moved to another file that is not SMP only. This is because the reset handler also be needed by CPU idle "powered-down" mode. So we also need to put the reset handler init function in non-SMP only and init them always. And currently the implementation of the reset handler to know which CPU is OK to bring up was identital with "cpu_present_mask". But the "cpu_present_mask" did not initialize yet when the reset handler init function was moved to init early function. We use the "cpu_possible_mask" to replace "cpu_present_mask". Then it can work on both UP and SMP case.

The device tree binding models this as a single monolithic clock provider, which exports many clocks. This reduces the number of nodes needed in device tree to represent these clocks. This binding is only useful for Tegra20; the set of clocks that exists on Tegra30 is sufficiently different to merit its own binding.

We need to check if there is any pending SGI when go into "powered-down" CPU idle mode. This is important especially when applying the coupled cpuidle framework into "power-down" cpuidle dirver. Because the coupled cpuidle framework may have the chance that misses IPI_SINGLE_FUNC handling sometimes. For the PPI or SPI, something like the legacy peripheral interrupt. It still can be maintained by Tegra legacy interrupt controller. If there is any pending PPI or SPI when CPU in "powered-down" CPU idle mode. The CPU can be woken up immediately.

When the secondary CPU requests to enter powered-down state, it saves its own contexts and then enters WFI. The Tegra20 had a limition to power down both CPU cores. The secondary CPU must waits for CPU0 in powered-down state too. If the secondary CPU be woken up before CPU0 entering powered-down state, then it needs to restore its CPU states and waits for next chance.

The coupled cpuidle framework can help to sync the MPCore to coupled state then go into "powered-down" idle mode together. The driver can just assume the MPCore come into "powered-down" mode at the same time. No need to take care if the CPU_0 goes into this mode along and only can put it into safe idle mode (WFI). The powered-down state of Tegra20 requires power gating both CPU cores. When the secondary CPU requests to enter powered-down state, it saves its own contexts and then enters WFI for waiting CPU0 in the same state. When the CPU0 requests powered-down state, it attempts to put the secondary CPU into reset to prevent it from waking up. Then power down both CPUs together and power off the cpu rail. Be aware of that, you may see the legacy power state "LP2" in the code which is exactly the same meaning of "CPU power down".

In case someone needs to add mx508 support back, then the recommended approach is to use device tree.

This happens because when global event did not expire any CPU local events, the broadcast device will be rearmed to a CPU local next_event, which could be far away from now and result in a max_delta_tick programming in set_next_event(). Fix the problem by detecting those next events with increments larger than 0x7fffffff, and simply return zero in that case. It leaves mx1_2_set_next_event() unchanged since only v2_set_next_event() will be running with imx6q WAIT mode support. Thanks Russell King for helping understand the problem.

When the link is brought up the bus can be scanned through /sys/bus/pci/rescan or otherwise. Since the HW has no interrupt for link up, userspace will have to take care of the timing. An earlier version of this was contingent on CONFIG_HOTPLUG, but that is being removed from the kernel. This also fixes printing the link up/down message to be displayed on one line (structured logging broke this?)
