2023-05-25arm: dts: k3-j721e: Refine MAIN domain ESM supportNeha Malcom Francis
MAIN domain ESM support was already added for J721E to configure main domain watchdog interrupts to generate ESM pin events. Move the main_esm node to be in sync with kernel dts. Also add register mapping for ESM in J721E. Signed-off-by: Neha Malcom Francis <n-francis@ti.com>
2021-10-03arm: ti: k3: Resync dts files and bindings with Linux Kernel v5.14Tom Rini
This resyncs the dts files for all of the currently in-tree K3 platforms, along with relevant bindings, with the v5.14 Linux Kernel release. Of note are that the main-navss/mcu-navss nodes were renamed to main_navss / mcu_navss and so the u-boot.dtsi files needed to be updated to match. Tested on j721e_evm and am65x_evm.

2021-04-16arm: dts: k3-j721e-main: Update the speed modes supported and their itap ↵Aswath Govindraju
delay values for MMCSD subsystems According to latest errata of J721e [1], HS400 mode is not supported in MMCSD0 subsystem (i2024) and SDR104 mode is not supported in MMCSD1/2 subsystems (i2090). Therefore, replace mmc-hs400-1_8v with mmc-hs200-1_8v in MMCSD0 subsystem and add a sdhci mask to disable SDR104 speed mode. Also, update the itap delay values for all the MMCSD subsystems according the latest J721e data sheet[2] [1] - https://www.ti.com/lit/er/sprz455/sprz455.pdf [2] - https://www.ti.com/lit/ds/symlink/tda4vm.pdf Fixes: 70e167495ab2 ("arm: dts: k3-j721e: Sync Linux v5.11-rc6 dts into U-Boot") Signed-off-by: Aswath Govindraju <a-govindraju@ti.com>

Sync all J721e related v5.11-rc6 Linux kernel dts into U-Boot. HBMC nodes are not yet added in Linux kernel yet but were added in U-Boot. In order to avoid any regressions, hbmc nodes are kept intact. These will be added in kernel in future. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>

2021-02-04remoteproc: k3_r5: Sync to upstreamed kernel DT property namesSuman Anna
The K3 R5F remoteproc driver in U-Boot was upstreamed prior to the equivalent remoteproc driver in the Linux kernel. Some of the DT properties used in U-Boot got upstreamed using different names in Linux kernel. The modified property names include the R5F cluster mode configuration property "lockstep-mode"; and three different individual R5F core config properties - "atcm-enable", "btcm-enable" and "loczrama". The property names were updated as follows: lockstep-mode => ti,cluster-mode atcm-enable => ti,atcm-enable btcm-enable => ti,btcm-enable loczrama => ti,loczrama Update the K3 R5F remoteproc driver, the corresponding binding, and all the existing usage in AM65x, J721E and J7200 dts files all at once to use the new properties and to not break any bisectability.

2020-09-15arm: dts: k3-j721e-main: Configure MAIN R5FSS1 for Split-modeSuman Anna
Switch the MAIN R5FSS1 cluster to be configured for Split-mode as the default so that two different applications can be run on each of the R5F cores in performance mode. LockStep-mode would be available only on SoCs efused with the appropriate bit, and Split-mode is the mode that is available on all J721E SoCs. Signed-off-by: Suman Anna <s-anna@ti.com>
2020-08-11arm: dts: k3: Add RTI watchdogsJan Kiszka
Add DT entries for main domain watchdog0 and 1 instances on the J721e well as RTI1-based watchdog on the AM65x. RTI0 does not work for this purpose on the AM65x, so leave it out. On AM65x, we mark the power-domain as shared because RTI firmware such as https://github.com/siemens/k3-rti-wdt may request it as well in order to prevent accidental shutdown of the watchdog.

2020-03-09mmc: am654_sdhci: Update output tap delay writesFaiz Abbas
With the latest RIOT, there is a different otap delay value for each speed mode. Add a new binding with every supported speed mode.

2019-10-11arm: dts: k3-j721e-main: Add C71x DSP nodeLokesh Vutla
The J721E SoCs have a single TMS320C71x DSP Subsystem in the MAIN voltage domain containing the next-generation C711 CPU core. The subsystem has 32 KB of L1D configurable SRAM/Cache and 512 KB of L2 configurable SRAM/Cache. This subsystem has a CMMU but is not used currently. The inter-processor communication between the main A72 cores and the C711 processor is achieved through shared memory and a Mailbox. Add the DT node for this DSP processor sub-system in the common k3-j721e-main.dtsi file. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
2019-10-11arm: dts: k3-j721e-main: Add C66x DSP nodesLokesh Vutla
The J721E SoCs have two TMS320C66x DSP Core Subsystems (C66x CorePacs) in the MAIN voltage domain, each with a C66x Fixed/Floating-Point DSP Core, and 32 KB of L1P & L1D configurable SRAMs/Cache and an additional 288 KB of L2 configurable SRAM/Cache. These subsystems do not have an MMU but contain a Region Address Translator (RAT) sub-module for translating 32-bit processor addresses into larger bus addresses. The inter-processor communication between the main A72 cores and these processors is achieved through shared memory and Mailboxes.

2019-10-11arm: dts: k3-j721e-main: Add MAIN domain R5F cluster nodesLokesh Vutla
The J721E SoCs have 3 dual-core Arm Cortex-R5F processor (R5FSS) subsystems/clusters. One R5F cluster (MCU_R5FSS0) is present within the MCU domain, and the remaining two clusters are present in the MAIN domain (MAIN_R5FSS0 & MAIN_R5FSS1). Each of these can be configured at boot time to be either run in a LockStep mode or in an Asymmetric Multi Processing (AMP) fashion in Split-mode. These subsystems have 64 KB each Tightly-Coupled Memory (TCM) internal memories for each core split between two banks - ATCM and BTCM (further interleaved into two banks). There are some IP integration differences from standard Arm R5 clusters such as the absence of an ACP port, presence of an additional TI-specific Region Address Translater (RAT) module for translating 32-bit CPU addresses into larger system bus addresses etc. Add the DT nodes for these two MAIN domain R5F cluster/subsystems, the two R5 cores are each added as child nodes to the corresponding main cluster node. Configure SS0 in split mode an SS1 in lockstep mode, with the ATCMs enabled to allow the R5 cores to execute code from DDR with boot-strapping code from ATCM.
