Eugeniy Paltsev 6d7489c74a clk: axs10x: introduce AXS10X pll driver ... AXS10X boards manages it's clocks using various PLLs. These PLL has same dividers and corresponding control registers mapped to different addresses. So we add one common driver for such PLLs. Each PLL on AXS10X board consist of three dividers: IDIV, FBDIV and ODIV. Output clock value is managed using these dividers. We add pre-defined tables with supported rate values and appropriate configurations of IDIV, FBDIV and ODIV for each value. As of today we add support for PLLs that generate clock for the following devices: * ARC core on AXC CPU tiles. * ARC PGU on ARC SDP Mainboard. and more to come later. By this patch we add support for two plls (arc core pll and pgu pll), so we had to use two different init types: CLK_OF_DECLARE for arc core pll and regular probing for pgu pll.
