Subject: [PATCH 4.17 066/220] ARM: dts: socfpga: Fix NAND controller clock supply

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Marek Vasut <marex@...x.de>

commit 4eda9b766b042ea38d84df91581b03f6145a2ab0 upstream.

The Denali NAND x-clock should be supplied by nand_x_clk, not by
nand_clk. Fix this, otherwise the Denali driver gets incorrect
clock frequency information and incorrectly configures the NAND
timing.
