ROC-RK3588S-PC 如何确认板卡引出的SPI接口驱动已加载？

bolun

已尝试刷过的固件，均可进入系统。
ROC-RK3588S-PC-RTLINUX_Ubuntu20.04-Gnome-r240_v1.1.1d_231018
ROC-RK3588S-PC-RTLINUX_Ubuntu20.04-Gnome-r240_v1.0.6f_230404
ROC-RK3588S-PC-EXT-RTLINUX_Ubuntu20.04-Gnome-r240_v1.1.1d_231018
ROC-RK3588S-PC-EXT_Ubuntu20.04-Gnome-r30028_v1.1.1b_230914

以上4套固件，进入系统后查看 /DEV中无类似 “/dev/spidev1.1”文件产生，而引出的UART7 有对应的"/dev/ttyS7"文件

查/var/log/syslog，有如下记录：
rockchip-spi feb10000.spi: no high_speed pinctrl state
rockchip-spi feb20000.spi: no high_speed pinctrl state
rk806 spi2.0: chip id RD806,ver:0x2,0x1
rk806 spi2.0: ON: 0x40 OFF: 0x0
rk806 spi2.0:  no sleep-setting state
rk806 spi2.0:  no reset-setting pinctrl state
rk806 spi2.0: no dvs-setting pinctrl state
register firefly_spi_init spi return v =:0
....
input: rk805 pwrkey as devices/platform/feb20000.spi/spi_master/spi2/spi2.0/rk805-pwrkey.2.auto/input/input6
....
register spi return v =:0
以上记录未发现SPI成功挂载的信息，而可查到UART7成功挂载的信息，如下：
feba0000.serial: ttyS7 at MMIO 0xfeba0000(irq = 92, base_baud = 1500000) is a 16550A

请大神帮忙判断下，是固件没刷对，还是需要额外进行配置？感谢了。
