      clk: oxnas: Add hardware dependencies · 821f9946
      Jean Delvare authored 
      The clk-oxnas driver is specific to its architecture, so do not
propose it on other architectures, unless build-testing.

      clk: imx7d: do not set parent of ethernet time/ref clocks · 5e33ebff
      Stefan Agner authored 
      All device trees currently in mainline specify the time clock parent
using the assigned-clocks/assigned-clock-parents method, there is no
need to statically assign the parent in the core clock driver.
Also all current boards provide an Ethernet reference clock for the
PHY externally, hence configuring the internal PHY reference clock.

Furthermore, and the actual driver of this patch, specify ethernet
related parents at that early point in boot leads to a warning:
bad: scheduling from the idle thread!

The reason for the warning is that setting the parent enables the ENET
PLL since we are using CLK_OPS_PARENT_ENABLE. Enabling the ENET PLL can
cause clk_pllv3_wait_lock to sleep. See also:
commit fc8726a2 ("clk: core: support clocks which requires parents
enable (part 2)").

Note that setting the ENET AXI root clock parent also requires ENET
PLL to be enabled. However, U-Boot typically leaves the ENET PLL on,
hence when the framework sets the parent of the first clock, it does
not need to wait for the PLL to come up. But because there is currently
no user of that clock, the PLL gets disabled after setting the parent.
Therefore, subsequent reparenting calls of any clock which somehow rely
on the ENET PLL, need to reenable the ENET PLL which leads to a sleep.
Removing those subsequent reparenting calls works around this issue.

Also remove comments. The code is really verbose enough.

      clk: sunxi: make clk-* explicitly non-modular · 439a36d7
      Paul Gortmaker authored 
      We have the following file --> Kconfig mapping:

sunxi/clk-factors.c              obj-y
sunxi/clk-sun6i-apb0-gates.c     CONFIG_MFD_SUN6I_PRCM (bool)
sunxi/clk-sun6i-apb0.c           CONFIG_MFD_SUN6I_PRCM
sunxi/clk-sun6i-ar100.c          CONFIG_MFD_SUN6I_PRCM
sunxi/clk-sun8i-apb0.c           CONFIG_MFD_SUN6I_PRCM
sunxi/clk-sun9i-mmc.c            obj-y

Hence none of these are being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only.  All
drivers get mostly the same changes, so they are handled in batch.

Changes are (1) convert to builtin_platform_register, (2) use the
init.h header, (3) delete the MODULE_LICENCE/MODULE_AUTHOR and
associated tags, and (4) delete any ".remove" functions.

There was a stray module.h in a file not using any init.h or
module.h stuff, so we simply removed that one.

In two cases, 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.

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

      clk: Kconfig: Name RK818 in Kconfig for COMMON_CLK_RK808 · cb98fd5d
      Wadim Egorov authored 
      The RK808 and RK818 PMICs are using a similar register map.
We can reuse the clk driver for the RK818 PMIC. So let's add
the RK818 in the Kconfig description.

      clk: hi6220: Change syspll and media_syspll clk to 1.19GHz · c6e80ace
      Xinliang Liu authored 
      In the bootloader of HiKey/96boards, syspll and media_syspll clk
was initialized to 1.19GHz. So, here changes it in kernel accordingly.

1.19GHz was chosen over 1.2GHz because at 1.19GHz we get more precise
HDMI pixel clock (1.19G/16 = 74.4MHz) for 1280x720p@60Hz HDMI
(74.25MHz required by standards). Closer pixel clock means better
compatibility to HDMI monitors.
