ARM: ux500: Configure regulator for I/O voltage for SD-card slot
Browse files Browse the repository at this point in the history 
To be able to enable SDR12|25 for SD-cards, we needed to fixup the
configuration in DT of the gpio regulator, which handles the signal
voltage level. Some configuration were missing and some were wrong.
