In common clock framework CLK_DIVIDER_ONE_BASED or'ed with
CLK_DIVIDER_ALLOW_ZERO flags indicates that
1) a divider clock may be set to zero value,
2) divider's zero value is interpreted as a non-divided clock.
On the LPC32xx platform clock dividers of PWM and memory card clocks
comply with the first condition, but zero value means a gated clock,
thus it may happen that the divider value is not updated when
the clock is enabled and the clock remains gated.
The change adds one-shot quirks, which check for zero value of divider
on initialization and set it to a non-zero value, therefore in runtime
a gate clock will work as expected.

The boot-time frequency of a CPU is considered its rated maximum, as we
have no other source of such information. However, this was previously
only used for chips with 80% restrictions on secondary PLLs. This
usually wasn't a problem because most chips/configs boot with a divider
of /1, with other dividers being used only for dynamic frequency
reduction. However, at least one config (LS1021A at less than 1 GHz)
uses a different divider for top speed. This was causing cpufreq to set
a frequency beyond the chip's rated speed.
This is fixed by applying a 100%-of-initial-speed limit to all CPU PLLs,
similar to the existing 80% limit that only applied to some.

The audio and video PLLs are designed to have a precision of 1 Hz if some
conditions are met. The current implementation only allows a precision that
depends on the rate of the parent clock. E.g., if the parent clock is 24
MHz, the precision will be 24 Hz; or more generally the precision will be
p / 10^6 Hz
where p is the parent clock rate. This comes down to how the register
values for the PLL's fractional loop divider are chosen.
The clock rate calculation for the PLL is
PLL output frequency = Fref * (DIV_SELECT + NUM / DENOM)
or with a shorter notation
r = p * (d + a / b)
In addition to all variables being integers, we also have the following
conditions:
27 <= d <= 54
-2^29 <= a <= 2^29-1
0 < b <= 2^30-1
|a| < b
Here, d, a and b are register values for the fractional loop divider. We
want to chose d, a and b such that f(p, r) = p, i.e. f is our round_rate
function. Currently, d and b are chosen as
d = r / p
b = 10^6
hence we get the poor precision. And a is defined in terms of r, d, p and
b:
a = (r - d * p) * b / p
I propose that if p <= 2^30-1 (i.e., the max value for b), we chose b as
b = p
We can do this since
|a| < b
|(r - d * p) * b / p| < b
|r - d * p| < p
Which have two solutions, one of them is when p < 0, so we can skip that
one. The other is when p > 0 and
p * (d - 1) < r < p * (d + 1)
Substitute d = r / p:
(r - p) < r < (r + p) <=> p > 0
So, as long as p > 0, we can chose b = p. This is a good choise for b since
a = (r - d * p) * b / p
= (r - d * p) * p / p
= r - d * p
r = p * (d + a / b)
= p * d + p * a / b
= p * d + p * a / p
= p * d + a
and if d = r / p:
a = r - d * p
= r - r / p * p
= 0
r = p * d + a
= p * d + 0
= p * r / p
= r
I reckon this is the intention by the design of the clock rate formula.

Since 'parent_rate * mfn' may overflow 32 bits, the result should be
stored using 64 bits.
The problem was discovered when trying to set the rate of the audio PLL
(pll4_post_div) on an i.MX6Q. The desired rate was 196.608 MHz, but
the actual rate returned was 192.000570 MHz. The round rate function should
have been able to return 196.608 MHz, i.e., the desired rate.

Usually, the 800MHz and 1GHz are supplied for CPLL and NPLL in the RK3399.
But dues to the carelessly copying from RK3036 when the RK3399 bringing up,
the refdiv == 6, it will increase the lock time, and it is not an optimal
configuration.
Let's fix them for the lock time and jitter are lower:
800 MHz:
- FVCO == 2.4 GHz, revdiv == 1.
1 GHz:
- FVCO == 3 GHz, revdiv == 1.

Due to incorrect placement of the clock gate cell in the ldb_di[x]_clk
tree, the glitchy parent mux of ldb_di[x]_clk can cause a glitch to
enter the ldb_di_ipu_div divider. If the divider gets locked up, no
ldb_di[x]_clk is generated, and the LVDS display will hang when the
ipu_di_clk is sourced from ldb_di_clk.
To fix the problem, both the new and current parent of the ldb_di_clk
should be disabled before the switch. This patch ensures that correct
steps are followed when ldb_di_clk parent is switched in the beginning
of boot. The glitchy muxes are then registered as read-only. The clock
parent can be selected using the assigned-clocks and
assigned-clock-parents properties of the ccm device tree node:
&clks {
assigned-clocks = <&clks IMX6QDL_CLK_LDB_DI0_SEL>,
<&clks IMX6QDL_CLK_LDB_DI1_SEL>;
assigned-clock-parents = <&clks IMX6QDL_CLK_MMDC_CH1_AXI>,
<&clks IMX6QDL_CLK_PLL5_VIDEO_DIV>;
};
The issue is explained in detail in EB821 ("LDB Clock Switch Procedure &
i.MX6 Asynchronous Clock Switching Guidelines") [1].

clk/samsung: Use CLK_OF_DECLARE_DRIVER initialization method for CLKOUT
|
|
The Exynos PMU node is an interrupt, clock and PMU (Power Management Unit)
controller, and these functionalities are supported by different drivers
that matches the same compatible strings.
Since commit 989eafd0b609 ("clk: core: Avoid double initialization of
clocks") the OF core flags clock controllers registered with the
CLK_OF_DECLARE() macro as OF_POPULATED, so platform devices with the same
compatible string will not be registered.
This prevents the PMU platform device to be created, so the Exynos PMU
driver is never probed. This breaks (among other things) Suspend-to-RAM.
Fix this by changing CLKOUT driver initialization method to
CLK_OF_DECLARE_DRIVER(), which doesn't clear the OF_POPULATED flag, so
later a platform device is created and the Exynos PMU platform driver
can be be probed properly.

On the A31, the DMA engine only works if AHB1 is clocked from PLL6.
In addition, the hstimer is clocked from AHB1, and if AHB1 is clocked
from the CPU clock, and cpufreq is working, we get an unstable timer.
Force the AHB1 clock to use PLL6 as its parent. Previously this was done
in the device tree with the assigned-clocks and assigned-clocks-parent
bindings. However with this new monolithic driver, the system critical
clocks aren't exported through the device tree. The alternative is to
force this setting in the driver before the clocks are registered.
This is also done in newer versions of mainline U-boot. But people still
using an older version, or even the vendor version, can still hit this
issue. Hence the need to do it in the kernel as well.

device node in DT can be used to initialize clock driver and populate
platform device for reset controller. But it stops working after
commit 989eafd0b609 ("clk: core: Avoid double initialization of clocks")
gets merged. The commit sets flag OF_POPULATED during clock
initialization to skip the platform device populating for the same
device node. On hi6220, it effectively makes hi6220-sysctrl reset
driver not probe any more.
