This\n adds tick-timer, adds compatibility of the board code for different\n USB probing, makes SPL smaller and updates the defconfig.\n\nThe series has been tested on am335x-evm. Note that I don't have all\nother boards built with the am335x_*evm_*defconfig, so tests are\nappreciated. buildman reports builds are working.\n\nDependencies:\n - net: cpsw: Add cpsw-switch DT binding support\n https://lore.kernel.org/r/20260410-topic-cpsw-switch-v2026-07-next-v1-0-c914724b13e4@baylibre.com\n\nBest,\nMarkus\n\nSigned-off-by: Markus Schneider-Pargmann (TI) <msp@baylibre.com>\n---\nChanges in v7:\n- Squash tick-timer patch for am335x-bonegreen-eco-u-boot into the patch\n that adds tick-timer for all other boards.\n- Remove dependency on (SPL_)CLK for (SPL_)SIMPLE_PM_BUS as clocks are\n optional now. Note I kept your reviewed-bys @Simon @Kory as I felt\n like this is a small change of the patch\n- Fixup USB probing for OF_UPSTREAM. Initial version of the patch probed\n USB host and USB gadget devices unconditionally. This is not necessary\n and also not what the old code did. The old code probed the\n ti-musb-wrapper driver which bound the usb host and usb gadget\n drivers, but it did not probe them.\n- Add CONFIG_PHANDLE_CHECK_SEQ to defconfig as many of the devices in\n the upstream devicetree have names like mmc@0 because they are within\n ti-sysc device nodes. The config symbol should help sorting them\n consistently anyways.\n- Link to v6: https://lore.kernel.org/r/20260415-topic-am33-evm-oftree-v2026-01-v6-0-94cde349bb01@baylibre.com\n\nChanges in v6:\n- Add patch to add am335x-bonegreen-eco-u-boot.dtsi which sets\n tick-timer\n- Add patch to remove all devicetrees that were moved to OF_UPSTREAM\n- Link to v5: https://lore.kernel.org/r/20260410-topic-am33-evm-oftree-v2026-01-v5-0-4b9c7aca0e3e@baylibre.com\n\nChanges in v5:\n- Add patch to add lcdc on beagle bone black to all boot phases. Without\n this patch booting uboot on bbb fails.\n- Add patch to split SIMPLE_PM_BUS into two, one for SPL and one for\n normal u-boot. This was done to reduce the size of SPL.\n- Link to v4: https://lore.kernel.org/r/20260127-topic-am33-evm-oftree-v2026-01-v4-0-0dadb0710ce7@baylibre.com\n\nChanges in v4:\n- Add patch to enable SPL_OPTIMIZE_INLINING to reduce size and fix the\n build\n- Link to v3: https://lore.kernel.org/r/20251204-topic-am33-evm-oftree-v2026-01-v3-0-3d1566ce4dc7@baylibre.com\n\nChanges in v3:\n- Add patch to unify all config variants for the am335x-evm and similar\n boards. This also updates the upstream defconfig enablement patch to\n effectively switch all config variants to OF_UPSTREAM.\n- Link to v2: https://lore.kernel.org/r/20251128-topic-am33-evm-oftree-v2026-01-v2-0-42a863304498@baylibre.com\n\nChanges in v2:\n- Most of the independent patches were extracted in smaller series\n- Added patch to add vidconsole for am335x-evm\n- Add chosen tick-timer to all devicetrees that are used with the\n am335x_evm_defconfig\n- Link to v1: https://lore.kernel.org/r/20251118-topic-am33-evm-oftree-v2026-01-v1-0-91ce13c661e2@baylibre.com\n\n---\nMarkus Schneider-Pargmann (TI) (14):\n arm: dts: am335x-evm: Add backlight to the panel\n configs: am335x_evm_defconfig: Enable panel\n include: configs: am335x_evm: Enable vidconsole\n configs: am335x_evm: Enable SPL_OPTIMIZE_INLINING\n configs: am335x_evm: Unify evm board defconfigs\n am33xx: Avoid hard failure on USB probe issue\n arm: dts: am335x-*-u-boot: Add chosen tick-timer\n arm: dts: am335x-boneblack-u-boot: Add lcdc to all boot phases\n am33xx: Fix comment about config symbols\n am33xx: Support upstream devicetree USB device\n dm: core: Split SIMPLE_PM_BUS into phases\n configs: am335x_evm_defconfig: Switch to upstream devicetree\n arm: dts: am335x: Remove unused uboot devicetrees\n dm: core: Remove dependency on CLK\n\n arch/arm/dts/Makefile | 11 -\n arch/arm/dts/am335x-bone-common-u-boot.dtsi | 14 +\n arch/arm/dts/am335x-bone-u-boot.dtsi | 6 +\n arch/arm/dts/am335x-bone.dts | 23 -\n arch/arm/dts/am335x-boneblack-u-boot.dtsi | 17 +\n arch/arm/dts/am335x-boneblack.dts | 174 -----\n arch/arm/dts/am335x-bonegreen-eco-u-boot.dtsi | 6 +\n arch/arm/dts/am335x-bonegreen-eco.dts | 53 --\n arch/arm/dts/am335x-bonegreen-u-boot.dtsi | 6 +\n arch/arm/dts/am335x-bonegreen.dts | 14 -\n arch/arm/dts/am335x-evm-u-boot.dtsi | 6 +\n arch/arm/dts/am335x-evm.dts | 766 ---------------------\n arch/arm/dts/am335x-evmsk-u-boot.dtsi | 6 +\n arch/arm/dts/am335x-evmsk.dts | 730 --------------------\n arch/arm/dts/am335x-icev2-u-boot.dtsi | 4 +\n arch/arm/dts/am335x-icev2.dts | 486 -------------\n arch/arm/dts/am335x-pocketbeagle-u-boot.dtsi | 6 +\n arch/arm/dts/am335x-pocketbeagle.dts | 237 -------\n arch/arm/dts/am335x-sancloud-bbe-common.dtsi | 67 --\n .../am335x-sancloud-bbe-extended-wifi-u-boot.dtsi | 6 +\n arch/arm/dts/am335x-sancloud-bbe-extended-wifi.dts | 113 ---\n arch/arm/dts/am335x-sancloud-bbe-lite.dts | 50 --\n arch/arm/dts/am335x-sancloud-bbe.dts | 53 --\n arch/arm/mach-omap2/am33xx/board.c | 23 +-\n configs/am335x_evm.config | 87 +++\n configs/am335x_evm_defconfig | 96 +--\n configs/am335x_evm_spiboot_defconfig | 85 +--\n configs/am335x_hs_evm.config | 14 +\n configs/am335x_hs_evm_defconfig | 95 +--\n configs/am335x_hs_evm_uart_defconfig | 94 +--\n drivers/core/Kconfig | 10 +-\n drivers/core/Makefile | 2 +-\n include/configs/am335x_evm.h | 2 +\n 33 files changed, 227 insertions(+), 3135 deletions(-)\n---\nbase-commit: 1c1bfb1cf34bbb2a5717eb6995c55093279f9341\nchange-id: 20251118-topic-am33-evm-oftree-v2026-01-ea701e03f8cf\nprerequisite-change-id: 20260410-topic-cpsw-switch-v2026-07-next-89e21f2d2446:v1\nprerequisite-patch-id: 896e00f13956d28e056dd63764ad8906a0b626ef\nprerequisite-patch-id: f612a9425d5a466c7585decbd8990d497a02cdfb\nprerequisite-patch-id: 9b18f917297f98b76a75f3d16536283b4c1bc76b\nprerequisite-patch-id: 2baa422fb10baa29bf4274a658eb7afba8c7b489\n\nBest regards," }
