I am fine with squashing this with the previous patch [PATCH 2/3] as well, if Bjorn is OK with it. Thanks, Bhupesh

I can squash the two while applying, unless anyone else have any concerns with the patches. Regards, Bjorn

Sounds good to me. Thanks for your help Bjorn with squashing the patches. Thanks, Bhupesh

Increase the l22 and l24 load used for uSD and eMMC VMMC. These need to be increased in order to prevent any voltage drop issues due to limited current happening during specific operations (e.g. write).
