7002483c7b clk: s2mps11: Remove useless check for clk_table
There is no need for checking if 'clk_table' is not NULL twice (first
after allocation and second at the end of probe()). Also move allocation
of this 'clk_table' to probe from s2mps11_clk_parse_dt as this is
logical place for it.

fe52e7505f clk: divider: Fix table round up function
Commit 1d9fe6b97 ("clk: divider: Fix best div calculation for power-of-two and
table dividers") introduces a regression in its _table_round_up function.

When the divider passed to this function is greater than the max divider
available in the table, this function returns table's max divider.
Problem is that it causes an infinite loop in clk_divider_bestdiv() because
_next_div() will never return a value greater than maxdiv.

Instead of returning table's max divider, this patch returns INT_MAX.

79c6ab5095 clk: divider: add CLK_DIVIDER_READ_ONLY flag
From: Heiko Stuebner <heiko@sntech.de>

Similar to muxes which already have a read-only flag there sometimes
exist dividers which should not be changed by the clock framework
but whose value still should be readable.

Therefore add a READ_ONLY flag similar to the mux-one to clk-divider

cb7d5f425f clk: sunxi: avoid double DT matching
Use for_each_matching_node_and_match instead of for_each_matching_node plus
of_match_node to avoid searching the DT twice for each node.

The sunxi DT scanning code should really be re-worked rather than have
its own private matching infrastructure. It is working around needing a
function pointer and a data pointer for each compatible match.

3b9334ac83 mfd: vexpress: Convert custom func API to regmap
Components of the Versatile Express platform (configuration
microcontrollers on motherboard and daughterboards in particular)
talk to each other over a custom configuration bus. They
provide miscellaneous functions (from clock generator control
to energy sensors) which are represented as platform devices
(and Device Tree nodes). The transactions on the bus can
be generated by different "bridges" in the system, some
of which are universal for the whole platform (for the price
of high transfer latencies), others restricted to a subsystem
(but much faster).

Until now drivers for such functions were using custom "func"
API, which is being replaced in this patch by regmap calls.
This required:

* a rework (and move to drivers/bus directory, as suggested
  by Samuel and Arnd) of the config bus core, which is much
  simpler now and uses device model infrastructure (class)
  to keep track of the bridges; non-DT case (soon to be
  retired anyway) is simply covered by a special device
  registration function

* the new config-bus driver also takes over device population,
  so there is no need for special matching table for
  of_platform_populate nor "simple-bus" hack in the arm64
  model dtsi file (relevant bindings documentation has
  been updated); this allows all the vexpress devices
  fit into normal device model, making it possible
  to remove plenty of early inits and other hacks in
  the near future

* adaptation of the syscfg bridge implementation in the
  sysreg driver, again making it much simpler; there is
  a special case of the "energy" function spanning two
  registers, where they should be both defined in the tree
  now, but backward compatibility is maintained in the code

* modification of the relevant drivers:

  * hwmon - just a straight-forward API change
  * power/reset driver - API change
  * regulator - API change plus error handling
    simplification
  * osc clock driver - this one required larger rework
    in order to turn in into a standard platform driver
