This is a note to let you know that I've just added the patch titled riscv: Fix Kendryte K210 device tree to the 5.8-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: riscv-fix-kendryte-k210-device-tree.patch and it can be found in the queue-5.8 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 6ed4a21689679044863b6ebceafb5c614bcc474b Author: Damien Le Moal <damien.lemoal@xxxxxxx> Date: Wed Sep 16 16:59:41 2020 +0900 riscv: Fix Kendryte K210 device tree [ Upstream commit f025d9d9934b84cd03b7796072d10686029c408e ] The Kendryte K210 SoC CLINT is compatible with Sifive clint v0 (sifive,clint0). Fix the Kendryte K210 device tree clint entry to be inline with the sifive timer definition documented in Documentation/devicetree/bindings/timer/sifive,clint.yaml. The device tree clint entry is renamed similarly to u-boot device tree definition to improve compatibility with u-boot defined device tree. To ensure correct initialization, the interrup-cells attribute is added and the interrupt-extended attribute definition fixed. This fixes boot failures with Kendryte K210 SoC boards. Note that the clock referenced is kept as K210_CLK_ACLK, which does not necessarilly match the clint MTIME increment rate. This however does not seem to cause any problem for now.
