Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.
Found with this grep:

I also reordered a couple includes when they weren't alphabetical and
removed clk.h from kona, replacing it with clk-provider.h because
that driver doesn't use clk consumer APIs.

The flags argument here is always 0, and we want to get rid of the flags
member of the clk_fixed_rate struct. So remove this here and just pass 0
when it's used.

* clk-divider-container:
clk: divider: fix incorrect usage of container_of
Plus fixup sprd/div.c to pass the width too.
|
|
divider_recalc_rate() is an helper function used by clock divider of
different types, so the structure containing the 'hw' pointer is not
always a 'struct clk_divider'
At the following line:
> div = _get_div(table, val, flags, divider->width);
in several cases, the value of 'divider->width' is garbage as the actual
structure behind this memory is not a 'struct clk_divider'
Fortunately, this width value is used by _get_val() only when
CLK_DIVIDER_MAX_AT_ZERO flag is set. This has never been the case so
far when the structure is not a 'struct clk_divider'. This is probably
why we did not notice this bug before
Fixes: afe76c8fd030 ("clk: allow a clk divider with max divisor when zero")

We need to export clk_gate_is_enabled() from clk framework, then
to avoid compilation issue we have to rename clk_gate_is_enabled()
in NXP LPC32xx clock driver.
We changed all gate op with 'lpc32xx_' prefix:
lpc32xx_clk_gate_enable(),
lpc32xx_clk_gate_disable(),
lpc32xx_clk_gate_is_enabled().

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.

This patch add the support to setup the HCLK PLL output
using the "assigned-clock-rates" parameter in the device tree.
If the option is not use, the clock setup by the kickstart
and/or bootloader remain unchanged.
The previous kernel version did not change the clock frequency
output setup by the kickstart and/or bootloader;
this version always setup the clock frequency output to 208MHz.

The list contains several heterogenous groups of clocks:
* system clocks including multiple dividers and muxes,
* x397 PLL, HCLK PLL and USB PLL,
* peripheral clocks inherited from rtc, hclk and pclk,
* USB controller clocks: AHB slave, I2C, OTG, OHCI and device.
