From 520557d4854b399606a6d2eb0666350ddad04f0c Mon Sep 17 00:00:00 2001 From: Jason Kridner Date: Sat, 4 Apr 2020 20:28:45 +0200 Subject: [PATCH 01/26] ARM: dts: am5729: beaglebone-ai: adding device tree BeagleBoard.org BeagleBone AI is an open source hardware single board computer based on the Texas Instruments AM5729 SoC featuring dual-core 1.5GHz Arm Cortex-A15 processor, dual-core C66 digital signal processor (DSP), quad-core embedded vision engine (EVE), Arm Cortex-M4 processors, dual programmable realtime unit industrial control subsystems and more. The board features 1GB DDR3L, USB3.0 Type-C, USB HS Type-A, microHDMI, 16GB eMMC flash, 1G Ethernet, 802.11ac 2/5GHz, Bluetooth, and BeagleBone expansion headers. For more information, refer to: https://beaglebone.ai This patch introduces the BeagleBone AI device tree. Note that the device use the "ti,tpd12s016" component which is software compatible with "ti,tpd12s015". Thus we only use the latter driver.

There are few pwm timers which are not selecting the clock source and relying on default value in hardware or selected by driver. Instead of relying on default value, always select the clock source from DT.

The IPU processor subsystem contains dual-core ARM Cortex-M4 processors, while the DSP processor subsystem is based on the TI's standard TMS320C66x DSP CorePac core. The IPUs are very similar to those on OMAP5. Two IPUs and one DSP processor subsystems is the most common configuration. The processor device DT nodes have been added for these processor subsystems, with the internal memories added through 'reg' and 'reg-names' properties. The IPUs only have an L2 RAM, whereas the DSPs have L1P, L1D and L2 RAM memories. NOTE: 1. The nodes do not have any mailboxes, timers or CMA regions assigned, they should be added in the respective board dts files. 2. The nodes haven been disabled by default and the enabling of these nodes is also left to the respective board dts files.

The latter file is for platforms having DRA74x/DRA76x/AM572x/AM574x SoCs which do have a DSP2 processor in addition to the other common remote processors. The common data is added to the former file, and the DSP2 only data is added to the latter file. The mailboxes are required for running the Remote Processor Messaging (RPMsg) stack between the host processor and each of the remote processors. Each of the remote processors uses a single sub-mailbox node, the IPUs are assumed to be running in SMP-mode. The chosen sub-mailboxes match the values used in the current firmware images. This can be changed, if needed, as per the system integration needs after making appropriate changes on the firmware side as well.

The data is added to the two common dra7-ipu-dsp-common and dra74-ipu-dsp-common dtsi files that are included by all the desired board files. The following timers are chosen, as per the timers used on the current firmware images: IPU2: GPTimer 3 IPU1: GPTimer 11 DSP1: GPTimer 5 DSP2: GPTimer 6 The timers are optional, but are mandatory to support advanced device management features such as power management and watchdog support. The above are added to successfully boot and execute firmware images configured with the respective timers, images that use internal processor subsystem timers are not affected. The timers can be changed or removed as per the system integration needs, if needed. Each of the IPUs has two Cortex-M4 processors, and is currently expected to be running in SMP-mode, so only a single timer suffices to provide the BIOS tick timer. An additional timer should be added for the second processor in IPU if it were to be run in non-SMP mode. The timer value also needs to be unique from the ones used by other processors so that they can be run simultaneously.

The data has been added to the two common dra7-ipu-dsp-common and dra74-ipu-dsp-common dtsi files that can be included by all the desired board files. The following timers are chosen as the watchdog timers, as per the usage on the current firmware images: IPU2: GPTimers 4 & 9 (one for each Cortex-M4 core) IPU1: GPTimers 7 & 8 (one for each Cortex-M4 core) DSP1: GPTimer 10 DSP2: GPTimer 13 Each of the IPUs has two Cortex-M4 processors and so uses a timer each for providing watchdog support on that processor irrespective of whether the IPU is running in SMP-mode or non-SMP node. The chosen timers also need to be unique from the ones used by other processors (regular timers or watchdog timers) so that they can be supported simultaneously. The MPU-side drivers will use this data to initialize the watchdog timer(s), and listen for any watchdog triggers. The BIOS-side code on these processors needs to configure/refresh the corresponding timer properly to not throw a watchdog error. The watchdog timers are optional in general, but are mandatory to be added to support watchdog error recovery on a particular processor. These timers can be changed or removed as per the system integration needs, alongside appropriate equivalent changes on the firmware side.
