Problem:
Some one may need to config pins via user space
Solution:
export some debugfs nodes from driver
usage:
1. echo gpiox_y input/output-low/high > gpio
2. echo gpiox_y bias-disable/up/down > bias
3. echo gpiox_y 500/2500/3000/4000 > drive_strength

Problem:
Kernel 6.6 only keeps dma_resv_list in dma_resv, so dma_resv_add_excl_fence
for exclusive fence is not used.
Usage of new interface dma_resv_add_fence() is incomplete, and that causes
error of NULL dma_resv_list pointer.
Solution:
Before dma_resv_add_fence(), dma_resv must have been locked with
dma_resv_lock(), and dma_resv_reserve_fences() must have been called.

2) Restart to uboot stage and compress the full DDR.
3) Set kernel dts rsv mem based on compressed infor.
4) Crop reserved memory sub nodes to reduce mem usage.
5) Kernel stage parsing dts to configure rsv mem.
6) Android init.rc read sysnode, and generate crash file.
