From 222a1f490722c60d73efaa3387e617ff5b730eb6 Mon Sep 17 00:00:00 2001 From: Sergiu Moga Date: Wed, 22 Jun 2022 16:30:47 +0300 Subject: mmc: atmel_sdhci: re-enable sdhci after SD Card re-insertion Whenever the SD Card would be removed and then re-inserted while in the U-Boot command line, the `SDBPWR` bit of the `SDMMC_PCR` register would remain unset afterwards. In order for the bit to be set again after re-insertion, register an additional `deferred_probe` method that the DM would then transparently call. This method will call the generic `sdhci_probe` which will, during its execution flow, set this bit to 1.
