Subject: [U-Boot] [PATCH v1] mmc: sdhci: SDHCI controllers also need power
Date: Wed, 15 Mar 2017 20:25:21 +0200 [thread overview]
Message-ID: <20170315182521.4359-1-andriy.shevchenko@linux.intel.com> (raw)
On some systems SDHCI controllers may be powered off and it's required
to bring them on before accessing.
SDHCI generic driver currently lacks any mean of doing it. Call the same
board_power_mmc_init() at sdhci_init() stage.
