Subject: drm/mgag200: Store positions of I2C data and clock bits in device
info
Git-commit: da1efdb2a3e8593a9428c81a531bfd8a0c3dd66e
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
The bits for accessing I2C data and clock channels varies among
models. Store them in the device-info structure for consumption
by the DDC code.
