Subject: [PATCH 0/2] clk: imx: Make the dram_apb and dram_alt as read-only

On i.MX8M platforms the dram_apb and dram_alt are controlled from EL3.
So in order to keep track of the actual clock tree in kernel, we need
to actually declare the clocks but never actually change their parents
or divider settings. We do that by marking the mux and the div as read-only
with CLK_DIVIDER_READ_ONLY and CLK_MUX_READ_ONLY flags.

Abel Vesa (2):
  clk: imx: composite-8m: Add DRAM clock registration variant
  clk: imx8m: Use dram variant registration for dram clocks
