Subject: spl: xea: Provide stub DM driver for imx28 clocks
X-Git-Url: http://git.dujemihanovic.xyz/repo?a=commitdiff_plain;h=9c2eefaf0d15368e9ca1bb7325e2b3baa263e448;p=u-boot.git

spl: xea: Provide stub DM driver for imx28 clocks

This code fixes following WARNING:
  DTOC    spl/dts/dt-plat.c
fsl_imx28_clkctrl: WARNING: the driver fsl_imx28_clkctrl was not found in the driver list

As imx28 doesn't yet support common clock framework, this prevents from
DTOC warnings during SPL build.
