硬件平台： RK3588 代码分支：develop-5.10 在这个平台做can的稳定性测试发现如下问题 https://github.com/rockchip-linux/kernel/commits/develop-5.10/drivers/net/can/rockchip/rockchip_canfd.c 在上述commit前后做对比测试。发现 [net: can: rockchip: support rk3568 can v2](https://github.com/rockchip-linux/kernel/commit/582cfd38c121900242ac54513c67e5517764884c)之后can数据解析丢包变严重。下图使用candump分析发现的问题，下图y轴表示同一个can ID的相邻数据时间间隔，单位ms 数据收到的时间间隔不均匀。但是数据是完整的没有丢包的数据。  
我用瑞芯微 6.1.99内核 打rt-6.1.99补丁，出现失败问题，对比内核源码，主要是8255串口芯片驱动很多CONFIG_ARCH_ROCKCHIP宏导致，请问如何解决
It seems FLEXBUS can be used to read and write parallel signals using GPIO and DMA at high frequency. But there is absolutely no information how to do it. Can...

**Description** We are seeing reproducible kernel crashes during H.264/H.265 decoding on RK3588 when using the RKVDEC driver. The issue appears in the decoder cleanup path `(mpp_dma_release → mpp_task_finalize → rkvdec_free_task)`....
