The zte zx platform is getting removed, so this driver is no
longer needed.

clk: zx296718: Don't reference clk_init_data after registration

2019-08-16T17:20:15+00:00

A future patch is going to change semantics of clk_register() so that
clk_hw::init is guaranteed to be NULL after a clk is registered. Avoid
referencing this member here so that we don't run into NULL pointer
exceptions.

clk: move clock common macros out from vendor directories

2017-12-21T23:00:38+00:00

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: constify clk_div_table

2017-08-31T05:30:30+00:00

clk_div_table are not supposed to change at runtime. All functions
working with clk_div_table provided by  work
with const clk_div_table. So mark the non-const structs as const.

clk: zte: add pll_vga clock for zx296718

2017-04-12T16:51:33+00:00

It adds zx296718 pll_vga clock for VGA support, so that VGA device can
get required pixel rate from clock driver for different display mode.

clk: zte: pd_bit is not 0 on zx296718

2017-04-12T16:51:31+00:00

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.
