Subject: [PATCH] BCM270X_DT: Fix the tinylcd35 overlay RTC support
|
|
|
|
Now that overlay parameters are applied before the merge (a requirement
|
|
for kernel runtime overlays) it is illegal for parameters/overrides to
|
|
target nodes in the base DTB. Solve the problem of only enabling I2C
|
|
when an RTC option is used by making the RTC fragments conditional,
|
|
and including the required status="okay" within the fragments.
