Add another entry in the wkup_conf for the syscon node, and then use that for the syscon in opp-table. Marking entire wkup_conf as "syscon", "simple-mfd" is wrong and needs to be addressed similar to how other child-nodes in wkup_conf are implemented in the same file. Signed-off-by: Dhruva Gole <d-gole@xxxxxx> --- This patch was sent previously here [1]. However there were some fixes needed in the driver to make it work which have to go in as well. The dependencies have been mentioned in the coverletter and a driver patch that needs to go in after this patch is included as part of this series itself.
