Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2015-11-10T23:00:03+00:00

Pull ARM SoC driver updates from Olof Johansson:
 "As we've enabled multiplatform kernels on ARM, and greatly done away
  with the contents under arch/arm/mach-*, there's still need for
  SoC-related drivers to go somewhere.

  Many of them go in through other driver trees, but we still have
  drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
  that might be shared between ARM and ARM64 (or just in general makes
  sense to not have under the architecture directory).

  This branch contains mostly such code:

   - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to
     communicate with power management blocks on these SoCs for use by
     clock, regulator and bus frequency drivers.

   - Allwinner Reduced Serial Bus driver, again used to communicate with
     PMICs.

   - Drivers for ARM's SCPI (System Control Processor).  Not to be
     confused with PSCI (Power State Coordination Interface).  SCPI is
     used to communicate with the assistant embedded cores doing power
     management, and we have yet to see how many of them will implement
     this for their hardware vs abstracting in other ways (or not at all
     like in the past).

   - To make confusion between SCPI and PSCI more likely, this release
     also includes an update of PSCI to interface version 1.0.

   - Rockchip support for power domains.

   - A driver to talk to the firmware on Raspberry Pi"

clk: berlin: bg2: remove CLK_IGNORE_UNUSED flag for sdio clk

2015-10-21T09:30:17+00:00

The clocks' properties have been already properly set, so there's no
need to set this flag for sdio0 and sdio1 clk any more.

clk: berlin: bg2q: remove CLK_IGNORE_UNUSED flag for sdio clk

2015-10-21T09:30:17+00:00

Since we have added the necessary two clks' properties in dts, we can
remove the "sdio" clk's CLK_IGNORE_UNUSED flag now.

clk: Convert __clk_get_name(hw->clk) to clk_hw_get_name(hw)

2015-08-24T23:49:12+00:00

Use the provider based method to get a clock's name so that we
can get rid of the clk member in struct clk_hw one day. Mostly
converted with the following coccinelle script.

struct clk_hw *E;

-__clk_get_name(E->clk)

2015-07-02T02:22:00+00:00

Pull clock framework updates from Michael Turquette:
 "The changes to the common clock framework for 4.2 are dominated by new
  drivers and updates to existing ones, as usual.

  There are some fixes to the framework itself and several cleanups for
  sparse warnings, etc"

clk: berlin: drop direct of_iomap of nodes reg property

2015-05-18T16:10:13+00:00

The Berlin clock driver was sharing a DT node with the pin controller
and the reset driver. All these devices are now sub-nodes of the chip
controller. This patch rework the Berlin clock driver to allow moving
the Berlin clock DT bindings into their own sub-node of the chip
controller node.

clk: berlin: bg2q: remove non-exist "smemc" gate clock

2015-01-13T18:58:43+00:00

The "smemc" clock is removed on BG2Q SoCs. In fact, bit19 of clkenable
register is for nfc. Current code use bit19 for non-exist "smemc"
incorrectly, this prevents eMMC from working due to the sdhci's
"core" clk is still gated.
