      clk: ti: make clk-dra7-atl explicitly non-modular · 172ff5a2
      Paul Gortmaker authored 
      

The Kconfig currently controlling compilation of this code is:

arch/arm/mach-omap2/Kconfig:config SOC_DRA7XX
arch/arm/mach-omap2/Kconfig:    bool "TI DRA7XX"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tags etc. since all that information
is already contained at the top of the file in the comments.

The Kconfig currently controlling compilation of this code is:

Since module_init translates to device_initcall in the non-modular

      clk: pxa: transfer CPU clock setting from pxa2xx-cpufreq · 9fe69429
      Robert Jarzmik authored 
      

This is the initial stage to transfer the pxa25x and pxa27x CPU clocks
handling from cpufreq to the clock API. More precisely, the clocks
transferred are :
 - cpll : core pll, known also as the CPU core turbo frequency
 - core : core, known also as the CPU actual frequency, being either the
          CPU core turbo frequency or the CPU core run frequency

This transfer is a prequel to shrink the code in pxa2xx-cpufreq.c, so
that it can become, at least in devicetree builds, the casual cpufreq-dt
driver.

      clk: sunxi: Fix M factor computation for APB1 · ac95330b
      Stéphan Rafin authored 
      commit cfa63688 ("clk: sunxi: factors: Consolidate get_factors
parameters into a struct") introduced a regression for m factor
computation in sun4i_get_apb1_factors function.

The old code reassigned the "parent_rate" parameter to the targeted
divisor value and was buggy for the returned frequency but not for the
computed factors. Now, returned frequency is good but m factor is
incorrectly computed (its max value 31 is always set resulting in a
significantly slower frequency than the requested one...)

This patch simply restores the original proper computation for m while
keeping the good changes for returned rate.

Fixes: cfa63688
