Changes since v10:
* Renamed everything from imx_clk_composite_8m to imx8m_clk_composite
Abel Vesa (1):
clk: imx: add imx composite clock
Lucas Stach (4):
dt-bindings: add binding for i.MX8MQ CCM
clk: imx: add fractional PLL output clock
clk: imx: add SCCG PLL type
clk: imx: add clock driver for i.MX8MQ CCM
