From: Linus Torvalds Date: Tue, 2 Aug 2022 15:15:25 +0000 (-0700) Subject: Merge tag 'arm-dt-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc X-Git-Tag: microblaze-v6.1~197 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=3976d758e045ed0485e0e665fb3b6692572576d7;hp=47d8f8b78b9b42e9817feeb75bbf758f2a3cbff8;p=linux-2.6-microblaze.git Merge tag 'arm-dt-6.0' of git://git./linux/kernel/git/soc/soc Pull ARM DT updates from Arnd Bergmann: "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 - Allwinner H616, a newer version of the H6 SoC, targeted at Set-top-box applications.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)" * tag 'arm-dt-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (829 commits) dt-bindings: soc: bcm: use absolute path to other schema dt-bindings: soc: bcm: drop quotes when not needed dt-bindings: soc: microchip: use absolute path to other schema dt-bindings: soc: microchip: drop quotes when not needed ARM: dts: lan966x: keep lan966 entries alphabetically sorted ARM: dts: lan966x: add support for pcb8309 dt-bindings: arm: at91: add lan966 pcb8309 board ARM: dts: lan966x: Enable network driver on pcb8291 ARM: dts: lan966x: Disable can0 on pcb8291 ARM: dts: lan966x: Add gpio-restart dt-bindings: arm: aspeed: add Aspeed Evaluation boards arm64: dts: qcom: Add support for Xiaomi Mi Mix2s dt-bindings: arm: qcom: Add Xiaomi Mi Mix2s bindings dt-bindings: arm: qcom: Document lg,judyln and lg,judyp devices dt-bindings: arm: qcom: add missing SM6350 board compatibles dt-bindings: arm: qcom: add missing SM6125 board compatibles dt-bindings: arm: qcom: add missing SDM845 board compatibles dt-bindings: arm: qcom: add missing SDM636 board compatibles dt-bindings: arm: qcom: add missing SDM630 board compatibles dt-bindings: arm: qcom: add missing QCS404 board compatibles ... --- diff --git a/.mailmap b/.mailmap index 2ed1cf869175..71577c396252 100644 --- a/.mailmap +++ b/.mailmap @@ -60,10 +60,17 @@ Arnd Bergmann Atish Patra Axel Dyks Axel Lin +Baolin Wang +Baolin Wang +Baolin Wang +Baolin Wang Bart Van Assche Bart Van Assche Ben Gardner Ben M Cahill +Ben Widawsky +Ben Widawsky +Ben Widawsky Björn Steinbrink Björn Töpel Björn Töpel @@ -132,6 +139,8 @@ Frank Rowand Frank Zago Gao Xiang Gao Xiang +Gao Xiang +Gao Xiang Gerald Schaefer Gerald Schaefer Gerald Schaefer @@ -368,6 +377,7 @@ Sean Nyekjaer Sebastian Reichel Sebastian Reichel Sedat Dilek +Seth Forshee Shiraz Hashim Shuah Khan Shuah Khan diff --git a/CREDITS b/CREDITS index 7e85a53b6a88..40d3c655b567 100644 --- a/CREDITS +++ b/CREDITS @@ -627,6 +627,10 @@ S: 48287 Sawleaf S: Fremont, California 94539 S: USA +N: Tomas Cech +E: sleep_walker@suse.com +D: arm/palm treo support + N: Florent Chabaud E: florent.chabaud@polytechnique.org D: software suspend diff --git a/Documentation/ABI/testing/sysfs-devices-system-cpu b/Documentation/ABI/testing/sysfs-devices-system-cpu index bcc974d276dc..df79e129d097 100644 --- a/Documentation/ABI/testing/sysfs-devices-system-cpu +++ b/Documentation/ABI/testing/sysfs-devices-system-cpu @@ -493,12 +493,13 @@ What: /sys/devices/system/cpu/cpuX/regs/ /sys/devices/system/cpu/cpuX/regs/identification/ /sys/devices/system/cpu/cpuX/regs/identification/midr_el1 /sys/devices/system/cpu/cpuX/regs/identification/revidr_el1 + /sys/devices/system/cpu/cpuX/regs/identification/smidr_el1 Date: June 2016 Contact: Linux ARM Kernel Mailing list Description: AArch64 CPU registers 'identification' directory exposes the CPU ID registers for - identifying model and revision of the CPU. + identifying model and revision of the CPU and SMCU.

Offloading the bridge means autonomously +learning FDB entries in accordance with the software bridge port's state, and +autonomously forwarding (or flooding) received packets without CPU intervention. +This is optional even when offloading a bridge port.
