Some bits are changed comparing to existing t9015, so new compatible string is still required. Second, I don't know anything about about ADC in t9015 on other SoCs and even don't sure that it exist there (may be I am inattentive, but I'm unable to find audio input pin on sm1/g12a's pinout). > Again, the t9015 changes should be a separated series from the rest, and > there should be one patch per topic. > > As Mark, if something is meant to be configured based on the HW layout, > then there a good change a kcontrol is not appropriate, and this should > rather be part of the platform description, like DT. > > It was also suggested here: > https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/sound/soc/meson/t9015.c?h=v6.8#n298 > Ok.
