2017-03-23ARM: dts: dra7: Add updated operating-points-v2 table for cpuDave Gerlach1-0/+5
After the ti-cpufreq driver has been added, we can now drop the operating-points table present in dra7.dtsi for the cpu and add an operating-points-v2 table with all OPPs available for all silicon revisions. Also add necessary data for use by ti-cpufreq to selectively enable the appropriate OPPs at runtime as part of the operating-points table. As we now need to define voltage ranges for each OPP, we define the minimum and maximum voltage to match the ranges possible for AVS class0 voltage as defined by the DRA7/AM57 Data Manual, with the exception of using a range for OPP_OD based on historical data to ensure that SoCs from older lots still continue to boot, even though more optimal voltages are now the standard. Once an AVS Class0 driver is in place it will be possible for these OPP voltages to be adjusted to any voltage within the provided range. Information from SPRS953, Revised December 2015.

2016-09-15Revert "ARM: dts: dra7: Move to operating-points-v2 table"Dave Gerlach1-1/+0
This reverts commit f80bc97fd0a9711ef11bdb3e63c2c01115a82c47. The original commit updated the cpufreq operating points tables for dra7xx but was merged before the driver making use of the node was merged, which breaks the existing cpufreq implementation on the system, so revert the patch until the ti-cpufreq driver is merged.

2015-10-13ARM: dts: DRA74x: Add dsp2_system syscon nodeSuman Anna1-0/+5
The DSP_SYSTEM sub-module is a dedicated system control logic module present within a DRA7 DSP processor sub-system. This module is responsible for power management, clock generation and connection to the device PRCM module. Add a syscon node for this module for the DSP2 processor sub-system. This is added as a syscon node as it is a common configuration module that can be used by the different IOMMU instances and the corresponding remoteproc device. The node is added to the dra74x.dtsi file, as the DSP2 processor subsystem is usually present only on the DRA74x variants of the DRA7 SoC family.

2015-10-13ARM: dts: DRA74x: Add IPC sub-mailbox nodes for all IPUs & DSPsSuman Anna1-0/+26
Add the sub-mailbox nodes that are used to communicate between MPU and the remote processors IPU1, IPU2, DSP1 and DSP2. The sub-mailbox nodes utilize the System Mailbox instances 5 and 6. These sub-mailbox nodes are added to match the hard-coded mailbox configuration used within the TI IPC 3.x software package. The Dual-Cortex M4 IPU1 and IPU2 processor sub-systems are assumed to be running in SMP-mode, and hence only a single sub-mailbox node is added for each. All these sub-mailbox nodes are left in disabled state, and should be enabled (and modified if needed) as per the individual product configuration in the corresponding board dts files.

2015-03-26ARM: dts: DRA7: Add bandgap and related thermal nodesKeerthy1-0/+5
Add bandgap and related thermal nodes. The patch adds 5 thermal sensors. Only one cooling device for mpu as of now. The sensors are the exact same on both dra72 and dra7. Introduce CPU, GPU, core nodes for the moment as they are direct reuse of OMAP5 entities. NOTE: OMAP4 has a finer counter granularity, which allows for a delay of 1000ms in the thermal zone polling intervals. DRA7 have different counter mechanism, which allows at maximum a 500ms timer. Adjust the cpu thermal zone accordingly for DRA7.

2015-03-15ARM: omap: convert wakeupgen to stacked domainsMarc Zyngier1-1/+1
OMAP4/5 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 WUGEN HW block, kernels with this patch applied won't have any suspend-resume facility when booted with old DTs, and old kernels with updated DTs won't even boot. On a platform with this patch applied, the system looks like this: root@bacon-fat:~# cat /proc/interrupts CPU0 CPU1 16: 0 0 WUGEN 37 gp_timer 19: 233799 155916 GIC 27 arch_timer 23: 0 0 WUGEN 9 l3-dbg-irq 24: 1 0 WUGEN 10 l3-app-irq 27: 282 0 WUGEN 13 omap-dma-engine 44: 0 0 4ae10000.gpio 13 DMA 294: 0 0 WUGEN 20 gpmc 297: 506 0 WUGEN 56 48070000.i2c 298: 0 0 WUGEN 57 48072000.i2c 299: 0 0 WUGEN 61 48060000.i2c 300: 0 0 WUGEN 62 4807a000.i2c 301: 8 0 WUGEN 60 4807c000.i2c 308: 2439 0 WUGEN 74 OMAP UART2 312: 362 0 WUGEN 83 mmc2 313: 502 0 WUGEN 86 mmc0 314: 13 0 WUGEN 94 mmc1 350: 0 0 PRCM pinctrl, pinctrl 406: 35155709 0 GIC 109 ehci_hcd:usb1 407: 0 0 WUGEN 7 palmas 409: 0 0 WUGEN 119 twl6040 410: 0 0 twl6040 5 twl6040_irq_ready 411: 0 0 twl6040 0 twl6040_irq_th IPI0: 0 1 CPU wakeup interrupts IPI1: 0 0 Timer broadcast interrupts IPI2: 95334 902334 Rescheduling interrupts IPI3: 0 0 Function call interrupts IPI4: 479 648 Single function call interrupts IPI5: 0 0 CPU stop interrupts IPI6: 0 0 IRQ work interrupts IPI7: 0 0 completion interrupts Err: 0 Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Link: https://lkml.kernel.org/r/1426088629-15377-8-git-send-email-marc.zyngier@arm.com Signed-off-by: Jason Cooper <jason@lakedaemon.net>

Support for the TI crossbar used on the DRA7 family of chips is implemented as an ugly hack on the side of the GIC. Converting it to stacked domains makes it slightly more palatable, as it results in a cleanup. Unfortunately, as the DT bindings failed to acknowledge the fact that this is actually yet another interrupt controller (the third, actually), we have yet another breakage. Oh well.
