2017-04-12clk: zte: pd_bit is not 0 on zx296718Shawn Guo1-1/+11
The bit 0 of PLL_CFG0 register is not powerdown on zx296718, but part of of postdiv2 field. The consequence is that functions like hw_to_idx() and zx_pll_enable() will end up tampering the postdiv2 of the PLL. Let's fix it by defining pd_bit 0xff which is obviously invalid for a bit position and having PLL driver check the validity before operating on the bit.

2017-01-09clk: zte: add audio clocks for zx296718Jun Nie1-0/+127
The audio related clock support is missing from the existing zx296718 clock driver. Let's add it, so that the upstream ZX SPDIF driver can work for HDMI audio support.
