arm-dt-5.20
47d8f8b7 · ·ARM: DT changes for 5.20 As usual, the bulk of the changes for the SoC tree are devicetree file updates, and most of these changes are for 64-bit embedded machines. As before, there are a ton of style cleanups, and additional hardware support for existing machines. Looking only at the new SoC, the notable additions are: - A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit: BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146, BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813. Each SoC comes with a corresponding reference board. - The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and i.MX8 embedded SoCs, now using Cortex-A55 cores and the Ethos-U65 NPU. - Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end of Arm based Laptop SoCs, and its automotive cousin, the SA8540P. The SC8280XP is used in the Lenovo Thinkpad X13s laptop that also gets added here in addition to the reference boards. - Allwinner H616, a newer version of the H6 SoC, targeted at Set-top-box applications. It comes with dts files for the Orange Pi zero2 single-board computer and the X96 Mate set-top-box - Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip in the Armada SoC family based on the Cortex-A55 core. New machines based on previously supported SoCs include: - Several new machines on NXP i.MX platforms: multiple Toradex Colibri boards using the "Iris" and "Ixora" carriers, DH electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems TQMa8MPQL, and phytech phyBOARD-Polis-i.MX8MM. - Google Chameleon v3 FPGA board based on Intel Arria10 and Stratix 10 Software Virtual platform, both in the SoCFPGA platform. - Two new wireless devices based on Broadcom SoCs: The Asus GT-AX6000 Router and the Cisco Meraki MR26 access point - Improved Chromebook support for both the Mediatek and Qualcomm SoC families brought added machines: Acer Chromebook 514 (MT8192), Acer Chromebook Spin 513 (MT8195) and a couple of SC7180 based machines including the Lenovo IdeaPad Chromebook Duet 3. - Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on Qualcomm SDM845, while Mi 5s Plus is based on MSM8996. - Finally, there are a few development board on other chips: PCB8309 (Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308) DH DRC Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm SDM660)

arm-soc-5.20
ARM: SoC updates for 5.20 The updates for arch/arm/mach-* platform code this time are mainly minor cleanups. Most notably, the DaVinci DM644x/DM646x SoC support gets removed. This was also scheduled for later removal early next year, but Linus Walleij asked for having them removed earlier to avoid problems for the GPIO subsystem.

arm-defconfig-5.20
c95a5712 · ·ARM: SoC defconfig updates for 5.20 This branch includes the usual updates to defconfig files, enabling additional driver support for the supported platforms. There is also a global refresh for all of them that reorders the lines according to the 'savedefconfig' output, but without removing lines that are no longer part of the refresh. I went through the most common removed lines to also address them while making sure to catch renamed options and add them back under the new name. The boardfile deprecation branch is based on top of this to avoid conflicts against removing the unused boardfile configs from the generic defconfig files.

arm-boardfiles-5.20
1785ab76 · ·ARM: boardfile deprecation for 5.20 Over the past ten years, new machine support was based on device tree, and an initial set of about 400 boards using ATAGS with boardfile for booting were grandfathered in, with about half of them either removed or converted to DT over time. Based on the recent mailing list discussion I started, I have now turned the findings into a set of patches that marks most board files as 'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards. For the boards that are marked as unused, there are two final chances for potential users: The removal is scheduled to take place after the longterm stable kernel at the end of 2022, so users can stay on that version for another few years, and if anyone still has one of these machines and is planning to keep updating kernels beyond that version, they can speak up now to have their boards taken off the list again. Waiting for the LTS release also makes sure that there will be at least one longterm kernel that contains the recent multiplatform conversion along while still supporting all legacy boards. The short summary of the current status is: - The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known users and will be removed entirely. - The mmp and davinci platforms have DT support for the important machines and will become DT-only after this. - s3c64xx, dove, orion5x, and pxa keep some board files to allow those to be migrated over to DT more easily, but most board files are getting removed now. DT support on these platforms is partially working but requires changes to additional drivers for the other boards. - omap1, ep93xx, sa1100, footbridge and rpc have no DT support at the moment but have some boards with known users. Removing the board files that nobody uses should make it easier to try a DT conversion if anyone cares. There is no explicit timeline what happens with the boards that remain after this removal, but I expect to revisit this in the future, and with most boards gone, there will be a good time to do a treewide review of platform drivers that never gained DT support and have no remaining in-tree board files.

soc-newsoc-5.20
bccd70a7 · ·ARM: new SoC support for 5.20 This adds initial support for two SoC families that have been under review for a while. In both cases, the origonal idea was to have a minimally functional version, but we ended up leaving out the clk drivers that are still under review and will be merged through the corresponding subsystem tree. The Nuvoton NPCM8xx is a 64-bit Baseboard Management Controller and based on the 32-bit NPCM7xx family but is now getting added to arch/arm64 as well. Sunplus SP7021, also known as Plus1, is a general-purpose System-in-Package design based on the 32-bit Cortex-A7 SoC on the main chip, plus an I/O chip and memory in the same package.
