2015-11-10Merge tag 'armsoc-drivers' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 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" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (57 commits) soc: qcom: smd-rpm: Correct size of outgoing message bus: sunxi-rsb: Add driver for Allwinner Reduced Serial Bus bus: sunxi-rsb: Add Allwinner Reduced Serial Bus (RSB) controller bindings ARM: bcm2835: add mutual inclusion protection drivers: psci: make PSCI 1.0 functions initialization version dependent dt-bindings: Correct paths in Rockchip power domains binding document soc: rockchip: power-domain: don't try to print the clock name in error case soc: qcom/smem: add HWSPINLOCK dependency clk: berlin: add cpuclk ARM: berlin: dts: add CLKID_CPU for BG2Q ARM: bcm2835: Add the Raspberry Pi firmware driver soc: qcom: smem: Move RPM message ram out of smem DT node soc: qcom: smd-rpm: Correct the active vs sleep state flagging soc: qcom: smd: delete unneeded of_node_put firmware: qcom-scm: build for correct architecture level soc: qcom: smd: Correct SMEM items for upper channels qcom-scm: add missing prototype for qcom_scm_is_available() qcom-scm: fix endianess issue in __qcom_scm_is_call_available soc: qcom: smd: Reject send of too big packets soc: qcom: smd: Handle big endian CPUs ...
2015-10-21clk: berlin: bg2: remove CLK_IGNORE_UNUSED flag for sdio clkJisheng Zhang
The clocks' properties have been already properly set, so there's no need to set this flag for sdio0 and sdio1 clk any more. Signed-off-by: Jisheng Zhang <jszhang@marvell.com> Signed-off-by: Michael Turquette <mturquette@baylibre.com>
2015-10-21clk: berlin: bg2q: remove CLK_IGNORE_UNUSED flag for sdio clkJisheng Zhang
Since we have added the necessary two clks' properties in dts, we can remove the "sdio" clk's CLK_IGNORE_UNUSED flag now. Signed-off-by: Jisheng Zhang <jszhang@marvell.com> Signed-off-by: Michael Turquette <mturquette@baylibre.com>

2015-08-24clk: Convert __clk_get_name(hw->clk) to clk_hw_get_name(hw)Stephen Boyd
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.

2015-05-18clk: berlin: drop direct of_iomap of nodes reg propertyAntoine Tenart
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.

2015-01-13clk: berlin: bg2q: remove non-exist "smemc" gate clockJisheng Zhang
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.

This is a clock driver for the simple PLLs found on Berlin SoCs.

2014-05-29clk: berlin: add driver for BG2x audio/video PLLSebastian Hesselbarth
This is a driver for the AVPLLs built upon a VCO with 8 channels each found on Marvell Berlin2 SoCs. While both VCOs found on BG2/BG2CD share the same register set, sometimes registers shifts for one of the VCOs are a bit off. Nothing serious that should require a separate driver, so deal with both VCOs in a single driver instead.
