Subject: [U-Boot] [PATCH v4 05/15] mmc: sdhci: Make sdhci_set_clock() non static
Date: Thu, 23 May 2019 12:37:42 -0500	[thread overview]
Message-ID: <20190523173752.28680-6-faiz_abbas@ti.com> (raw)
In-Reply-To: <20190523173752.28680-1-faiz_abbas@ti.com>

The am654_sdhci driver needs to switch the clock off
before disabling its phy dll and needs to re-enable
the clock before enabling the phy again.

Therefore, make the sdhci_set_clock() function accessible
in the am654_sdhci driver.
