clk: boston: Add a driver for MIPS Boston board clocks

2017-07-11T12:13:06+00:00

Add a driver for the clocks provided by the MIPS Boston board from
Imagination Technologies. 2 clocks are provided - the system clock & the
CPU clock - and each is a simple fixed rate clock whose frequency can be
determined by reading a register provided by the board.

clk: Add Gemini SoC clock controller

2017-06-21T17:45:54+00:00

The Cortina Systems Gemini (SL3516/CS3516) has an on-chip clock
controller that derive all clocks from a single crystal, using some
documented and some undocumented PLLs, half dividers, counters and
gates. This is a best attempt to construct a clock driver for the
clocks so at least we can gate off unused hardware and driver the
PCI bus clock.

clk: keystone: Add sci-clk driver support

2017-06-14T16:05:07+00:00

In K2G, the clock handling is done through firmware executing on a
separate core. Linux kernel needs to communicate to the firmware
through TI system control interface to access any power management
related resources, including clocks.

The keystone sci-clk driver does this, by communicating to the
firmware through the TI SCI driver. The driver adds support for
registering clocks through DT, and basic required clock operations
like prepare/get_rate, etc.

Merge branch 'clk-bulk-get' into clk-next

2017-06-02T22:39:32+00:00

* clk-bulk-get:
  clk: add managed version of clk_bulk_get
  clk: add clk_bulk_get accessories

clk: add clk_bulk_get accessories

2017-06-02T22:37:45+00:00

These helper function allows drivers to get several clk consumers in
one operation. If any of the clk cannot be acquired then any clks
that were got will be put before returning to the caller.

This can relieve the driver owners' life who needs to handle many clocks,
as well as each clock error reporting.

clk: renesas: Rework Kconfig and Makefile logic

2017-05-24T08:19:28+00:00

The goals are to:
  - Allow precise control over and automatic selection of which
    (sub)drivers are used for which SoC (which may change in the
    future),
  - Allow adding support for new SoCs easily,
  - Allow compile-testing of all (sub)drivers,
  - Keep driver selection logic in the subsystem-specific Kconfig,
    independent from the architecture-specific Kconfig (i.e. no "select"
    from arch/arm64/Kconfig.platforms), to avoid dependencies.

This is implemented by:
  - Introducing Kconfig symbols for all drivers and sub-drivers,
  - Introducing the Kconfig symbol CLK_RENESAS, which is enabled
    automatically when building for a Renesas ARM platform, and which
    enables all required drivers without interaction of the user, based
    on SoC-specific ARCH_* symbols,
  - Allowing the user to enable any Kconfig symbol manually if
    COMPILE_TEST is enabled,
  - Using the new Kconfig symbols instead of the ARCH_* symbols to
    control compilation in the Makefile,
  - Always entering drivers/clk/renesas/ during the build.

Note that currently not all (sub)drivers are enabled for
compile-testing, as they depend on independent fixes in other
subsystems.

clk: hi6220: Add the hi655x's pmic clock

2017-04-22T02:18:53+00:00

The hi655x multi function device is a PMIC providing regulators.

The PMIC also provides a clock for the WiFi and the Bluetooth, let's implement
this clock in order to add it in the hi655x MFD and allow proper wireless
initialization.

clk: vc5: Add support for IDT VersaClock 5P49V5923 and 5P49V5933

2017-01-21T00:17:34+00:00

Add driver for IDT VersaClock 5 5P49V5923 and 5P49V5933 chips. These
chips have two clock inputs, XTAL or CLK, which are muxed into single
PLL/VCO input. In case of 5P49V5923, the XTAL in built into the chip
while the 5P49V5923 requires external XTAL.

The PLL feeds two fractional dividers. Each fractional divider feeds
output mux, which allows selecting between clock from the fractional
divider itself or from output mux on output N-1. In case of output
mux 0, the output N-1 is instead connected to the output from the mux
feeding the PLL.

The driver thus far supports only the 5P49V5923 and 5P49V5933, while
it should be easily extensible to the whole 5P49V59xx family of chips
as they are all pretty similar.
