* clk: move clock common macros out from vendor directoriesChunyan Zhang2017-12-211-18/+0
| | | | | | | | | These macros are used by more than one SoC vendor platforms, avoid to have many copies of these code, this patch moves them to the common header file which every clock drivers can access to.

* clk: zte: pd_bit is not 0 on zx296718Shawn Guo2017-04-121-1/+5
| | | | | | | | | | | | | | | 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.

* clk: zte: add audio clocks for zx296718Jun Nie2017-01-091-0/+21
| | | | | | | | | | | 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.

* clk: zx: add clock support to zx296702Jun Nie2015-06-111-0/+32
It adds a clock driver for zx296702 SoC to register the clock tree to Common Clock Framework. All the clocks of bus topology and some the peripheral clocks are ready with this commit. Some missing leaf clocks for peripherals will be added later when needed.
