On i.MX6Q TO > 1.0, i.MX6DL and i.MX6SX, gpt per clock
can be from OSC instead of ipg_per, as ipg_per's rate
may be scaled when system enter low bus mode, to keep
system timer NOT drift, better to make gpt per clock
at fixed rate, here add support for gpt per clock to
be from OSC which is at fixed rate always.
There are some difference on this implementation of
gpt per clock source, see below for details:
i.MX6Q TO > 1.0: GPT_CR_CLKSRC, b'101 selects fix clock
of OSC / 8 for gpt per clk;
i.MX6DL and i.MX6SX: GPT_CR_CLKSRC, b'101 selects OSC
for gpt per clk, and we must enable GPT_CR_24MEM to
enable OSC clk source for gpt per, GPT_PR_PRESCALER24M
is for pre-scaling of this OSC clk, here set it to 8
to make gpt per clk is 3MHz;
i.MX6SL: ipg_per can be from OSC directly, so no need to
implement this new clk source for gpt per.

The imx6q clock driver currently hard-codes all PLL clocks to source
from OSC24M without BYPASS support. The patch adds the missing lvds_in

and BYPASS_CLK_SRC selection for PLL clocks as per Figure 10-3. Primary
Clock Generation in IMX6DQRM, i.e. both BYPASS_CLK_SRC and BYPASS bits
are implemented as mux clocks, and ENABLE bit of PLL clocks is
implemented as a gate clock after BYPASS mux.

There are a couple of gate clocks are mutually exclusive on i.MX6, i.e.
LVDSCLK1_IBEN and LVDSCLK1_OBEN. They cannot be enabled simultaneously.
This patches adds an exclusive gate clock type specifically for such
case. The clock driver will need to call imx_clk_gate_exclusive() to
register a gate clock with parameter exclusive_mask indicating the mask
of gate bits which are mutually exclusive to this gate clock.
Right now, it only handles the exclusive gate clocks which are defined
in a single hardware register, which is the case we're running into
today. But it can be extended to handle exclusive gate clocks defined
in different registers later if needed.

At the end of the boot process, the clock framework might disable
required main PLL's. So far, this was no issue since drivers
requested clocks, which are descended of the main PLL's (e.g.
pll1_pfd1, which provides the system clock).
To archive the full 500MHz system clock, DDR clock need to be a
descendant of PLL2 rather than PLL1 (DDRC_CLK_SEL set to 0). The
bootloader sets up the clocks accordingly before making use of
DDR at all. However, in Linux, there is no driver using PLL2,
which lead to PLL2 being disabled by the clock framework.
With this patch, we make sure that the main system clock and the
DDR clock are initially enabled and are kept enabled.

In general Renesas hardware is not documented to the extent

documentation typically does not specify a version for individual

of a version and providing SoC-specific compat strings has been adopted.
