[PATCH 0/8] Add support for Qualcomm SA8155-ADP board
by Volodymyr Babchuk 05 Mar '24

05 Mar '24

This patch series adds support for Qualcomm SA8155-ADP development board. Main motivation for this series is to allow running virtualization software on this board and U-Boot is a good way to break Qualcomm's boot chain at EL2 with more convenient ways for uploading and running the code. With this patches applied it is possible to upload and run Xen on this board. KVM probably should work too. I added myself as a maintainer for this board, but my abilities to maintain it are quite limited as I have no access to Qualcomm documentation. I used mostly Linux drivers as the source for device-specific information, like register addresses and offsets. If anyone wants to maintain this, I will gladly agree.

Hello Everyone! This series will introduce basic support (SD and UART) support for Texas Instruments J784S4 EVM. The J784S4 SoC device tree patches are taken from kernel patch submissions and will be updated as they are accepted and merged to the kernel tree. All other patches are specific to SPL and u-boot and do not have dependency on other trees. Appreciate a review for acceptance to u-boot tree. Here are some of the salient features of the J784S4 automotive grade application processor: The J784S4 SoC belongs to the K3 Multicore SoC architecture platform, providing advanced system integration in automotive, ADAS and industrial applications requiring AI at the network edge. This SoC extends the K3 Jacinto 7 family of SoCs with focus on raising performance and integration while providing interfaces, memory architecture and compute performance for multi-sensor, high concurrency applications. Some highlights of this SoC are: * Up to 8 Cortex-A72s, four clusters of lockstep capable dual Cortex-R5F MCUs, 4 C7x floating point vector DSPs with Matrix Multiply Accelerator(MMA) for deep learning and CNN. * 3D GPU: Automotive grade IMG BXS-4-64 MC1 * Vision Processing Accelerator (VPAC) with image signal processor and Depth and Motion Processing Accelerator (DMPAC) * Three CSI2.0 4L RX plus two CSI2.0 4L TX, two DSI Tx, one eDP/DP and one DPI interface. * Integrated gigabit ethernet switch, up to 8 ports (TDA4VH), two ports support 10Gb USXGMII; Two 4 lane PCIe-GEN3 controllers, USB3.0 Dual-role device subsystems, Up to 20 MCANs, among other peripherals. See J784S4 Technical Reference Manual (SPRUJ52 - JUNE 2022) for further details: http://www.ti.com/lit/zip/spruj52 In addtion, the J784S4 EVM board is designed for TI J784S4 SoC. It supports the following interfaces: * 32 GB DDR4 RAM * x2 Gigabit Ethernet interfaces capable of working in Switch and MAC mode * x1 Input Audio Jack, x1 Output Audio Jack * x1 USB2.0 Hub with two Type A host and x1 USB 3.1 Type-C Port * x2 4L PCIe connector * x1 UHS-1 capable micro-SD card slot * 512 Mbit OSPI flash, 1 Gbit Octal NAND flash, 512 Mbit QSPI flash, UFS flash. * x6 UART through UART-USB bridge * XDS110 for onboard JTAG debug using USB * Temperature sensors, user push buttons and LEDs * 40-pin User Expansion Connector * x2 ENET Expansion Connector, x1 GESI expander, x2 Display connector * x1 15-pin CSI header * x6 MCAN instances Schematics: https://www.ti.com/lit/zip/sprr458 AM69 SD mode bootlog: https://gist.githubusercontent.com/apurvanandan1997/1b2c55d0204ff0f5a47ebbc… J784S4 SD mode bootlog: https://gist.githubusercontent.com/apurvanandan1997/5e2ef85ee4322798d22b57a… eMMC UDA moode bootlog: https://gist.githubusercontent.com/apurvanandan1997/3cffada252d50a8aa0c00a9… Note: This series is dependent on the following series for OF_UPSTREAM support https://lore.kernel.org/all/20240222093607.3085545-1-sumit.garg@linaro.org/ And, '[PATCH 01/15] Makefile: remove hardcoded device tree source directory' has been cherry-picked from PATCH 11 of https://lore.kernel.org/all/20240201030634.1120963-16-bb@ti.com/ by Bryan Brattlof Changes in v10: 1) Fixed build failure due to missing OF_UPSTREAM in a72 defconfigs 2) Updated paths of board dtbs in binman.dtsi, CONFIG_OF_LIST and CONFIG_DEFAULT_DEVICE_TREE Changes in v9: 1) Added support for OF_UPSTREAM and removed Linux dts copy/sync patches 2) Fixed DRAM enumeration algorithm in j784s4_init.c by adding max no. of controllers 3) Squashed bootph-all property of memory node into appropriate patch 4) Moved DDR changes out of the DMA patch 5) Fixed commit messages, MAINTAINERS file, and removed unnecessary C headers 6) Added comment for WKUP_UART0 7) Used #include for defconfig for AM69-SK platform instead of config fragments 8) Fixed J784S4 EVM boot switch nameing in doc Link to v8: https://lore.kernel.org/u-boot/20240119175043.3904751-1-a-nandan@ti.com/ Changes in v8: 1) Squashed Linux am69-sk and j784s4-evm dts patches into one 2) Sorted config addition of SoC in arm/mach-K3/Kconfig 3) Updated commit messages according to the reviews 4) Removed #inlcude <config.h> 5) Removed k3_mmc_stop_clock and k3_mmc_restart_clock 6) Moved board_init_f logic to separate smaller functions 7) Removed J784S4 EVM specific Kconfig options in j784s4_int.c 8) Cleaned up emmc boot flow based on commit 66459346463439c72f84cfd1f985496b8a6142d8 9) Removed the dependency of findfdt and updated to ti_set_fdt_env 10) Updated copyright messages 11) Did cleanup/formatting of yaml files, removing linting errors 12) Removed k3-am69-sk specific things from k3-j784s4-binman.dtsi 13) Changed OF_LIST to a single dtb 14) Added bootph-all tag in EVM and SK dts instead of u-boot.dtsi 15) Trimmed the defconfig files to minimal 16) Merged the MAINTAINER file in right patches 17) Updated OpenOCD tag in U-Boot doc 18) And fixed other formatting mistakes.

[PATCH v2] dma: ti: k3-udma: Fix ring_idx to pair k3 nav rings
by Udit Kumar 05 Mar '24

ring_idx was not correctly assigned in case of tflow_id is zero. Which leads to wrong pairing of DMA for drivers like OSPI.

[PATCH] board: ti: rm-cfg: Update rm-cfg to reflect new resource reservation
by Vishal Mahaveer 05 Mar '24

05 Mar '24

With the latest TIFS firmware, an additional virtual interrupt and event is reserved for TIFS usage on am62x and am62ax devices. Update the rm-cfg to reflect this new reservation.

[PATCH v2] dma: ti: k3-udma: Fix error handling for setup_resources() in udma_probe()
by Siddharth Vadapalli 05 Mar '24

05 Mar '24

In udma_probe() the return value of setup_resources() is stored in the u32 "ch_count" member of "struct udma_dev", due to which any negative return value which indicates an error is masked. Fix this by storing the return value of setup_resources() in the already declared integer variable "ret", followed by assigning it to the "ch_count" member of "struct udma_dev" in case of no error. While at it, change the "return ret" at the end of udma_probe() to a "return 0", to explicitly indicate that probe was successful.

[PATCH V2 0/5] board: beagle: Enable 32k and debounce configuration and fixups
by Nishanth Menon 05 Mar '24

05 Mar '24

Hi, Rev 2 of the series. This is a follow up from [1] - Without the 32k crystal configuration, wlan doesn't work. Debounce is needed for HDMI Hot plug detect(hpd) gpio interrupt not storming. At least the 32k configuration has been done for toradex and phytec boards, follow similar model of programming. Series is now based off master branch. Bootlog: https://gist.github.com/nmenon/75df38bee907785d1d78d1ec4abd7304 Changes from V2: - Removed depedency on [2] - depending on which way the merge sequence goes, one of the series will need a rebase. - Added a patch for a bug that Jan noticed - Fixup for the fat finger missing 0x in 0x4080 :( V1: https://lore.kernel.org/all/20240212155332.541949-1-nm@ti.com/ Nishanth Menon : board: beagle: beagleplay: Enable 32k crystal configs: am62x_beagleplay_r5_defconfig: Enable SPL_BOARD_INIT arm: mach-k3: am62: Add Debounce configuration register definitions board: beagle: beagleplay: Configure debounce registers board: beagle: beagleplay: env: Drop usb and pxe as boot targets arch/arm/mach-k3/include/mach/am62_hardware.h | 3 + board/beagle/beagleplay/beagleplay.c | 61 +++++++++++++++++++ board/beagle/beagleplay/beagleplay.env | 2 +- configs/am62x_beagleplay_r5_defconfig | 1 + 4 files changed, 66 insertions(+), 1 deletion(-) base-commit: 3e6f2a94bfc25f1782ce2d45db27f47ec781feb1 [1] https://lore.kernel.org/u-boot/20230725185253.2123433-4-nm@ti.com/ [2] https://lore.kernel.org/u-boot/20240212194726.1093771-1-nm@ti.com/ -- 2.43.0
