Hi Yinbo,
I love your patch! Yet something to improve:
[auto build test ERROR on broonie-spi/for-next]
[also build test ERROR on robh/for-next krzk-dt/for-next linus/master v6.3-rc3 next-20230324]

cc1: some warnings being treated as errorThe devm_ioremap was declared in linux/io.h, and I think add include
<linux/io.h> in spi-loongson-core.c that compile issue will be fixed.
