Upstream Xavier SDMMC needs some love. I've been able to test with a Jetson AGX Xavier.
Changes here work for me with 1.8 V and 3.3 V SD and SDIO devices.
Changes in v3:
- I started seeing ocasional eMMC init timeouts on cold starts when HS400 is enabled, so drop this until fix is found
- add missing vmmc-supply regulator for SDMMC1
- specify bus width and disable WP for SDMMC1
- specify primary clock source for SDMMC1 and SDMMC3
Changes in v2:
- fix board name in commit messages
- rebase on for-next
Kind regards,
Tamas
