Please move the config changes into a separate commit once you've responded to other feedback (i.e. you don't need to do it yet).

And include the 32-bit defconfigs, unless there is a reason they won't be compatible.

Thanks, I’ll split the defconfig updates into a separate commit and add CONFIG_TOUCHSCREEN_ST7123=m to the 32-bit Raspberry Pi defconfigs as well.
Our hardware testing so far has been on the 64-bit kernel. The driver only depends on I2C and is built as a module,so I don’t see an obvious 32-bit-specific compatibility issue.
