| Subject: ARM: shmobile: henninger: add SDHI0/2 DT support |
| |
| Define the Henninger board dependent part of the SDHI0/2 device nodes along with |
| the necessary voltage regulators (note that the Vcc regulators are dummy -- they |
| are required but don't actually exist on the board). Also, GPIOs have to be used |
| for the CD and WP signals due to the SDHI driver constraints... |
