2015-12-02clk: sunxi: pll2: Fix clock running too fastMaxime Ripard
Contrary to what the datasheet says, the pre divider doesn't seem to be incremented by one in the PLL2, but just uses the value from the register, with 0 being a bypass. This fixes the audio playing too fast. Since we now have the same pre-divider flags, and the only difference with the A10 is the post-divider offset, also remove the structure to just pass the offset as an argument.

2015-12-02ARM: imx: clk-vf610: fix SAI clock treeStefan Agner
The Synchronous Audio Interface (SAI) instances are clocked by independent clocks: The bus clock and the audio clock (as shown in Figure 51-1 in the Vybrid Reference Manual). The clock gates in CCGR0/CCGR1 for SAI0 through SAI3 are bus clock gates, as access tests to the registers with/without gating those clocks have shown. The audio clock is gated by the SAIx_EN gates in CCM_CSCDR1, followed by a clock divider (SAIx_DIV). Currently, the parent of the bus clock gates has been assigned to SAIx_DIV, which is not involved in the bus clock path for the SAI instances (see chapter 9.10.12, SAI clocking in the Vybrid Reference Manual). Fix this by define the parent clock of VF610_CLK_SAIx to be the bus clock. If the driver needs the audio clock (when used in master mode), a fixed device tree is required which assign the audio clock properly to VF610_CLK_SAIx_DIV.

for_each_available_child_of_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put.

2015-11-25clk: mmp: add linux/clk.h includesArnd Bergmann
The common clk implementation for MMP broke without anyone noticing when we stopped including linux/clk.h from the clk-provider header. This did not show up in the defconfig builds because those use the legacy MMP clk drivers, and it did not show up in my randconfig tests either because I was testing with my mmp multiplatform series applied, which at some point gained the fixup.

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 ...

2015-10-26clk: lpc18xx-cgu: fix potential system hang when disabling unused clocksJoachim Eastwood
The clock consumer (CCU) of the CGU must be able to check if a CGU base clock is really running since access to the CCU registers requires a running base clock. Access with a disabled base clock will cause the system to hang. Fix this issue by adding code that check if the parent clock is running in the is_enabled clk_ops callback. Since certain clocks can be cascaded this must be added to all clock gates. The hang would occur if the boot ROM or boot loader didn't setup and enable the USB0 clock. Then when the clk framework tried to access the CCU register it would hang the system. Signed-off-by: Joachim Eastwood <manabian@gmail.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2015-10-26clk: lpc18xx-ccu: fix potential system hang when disabling unused clocksJoachim Eastwood
CCU branch clock register must only be accessed while the base (parent) clock is running. Access with a disabled base clock will cause the system to hang. Fix this issue by adding code that check if the parent clock is running in the is_enabled clk_ops callback. This hang would occur when disabling unused clocks after AMBA runtime pm had already disabled some of the clocks.

2015-10-26clk: rockchip: Allow more precision for some mmc clock phasesDouglas Anderson
Because of the inexact nature of the extra MMC delay elements (it's not possible to keep the phase monotonic and to also make phases (mod 90) > 70), we previously only allowed phases (mod 90) of 22.5, 45, and 67.5. But it's not the end of the world if the MMC clock phase goes non-monotonic. At most we'll be 25 degrees off. It's way better to test more phases to look for bad ones than to be 25 degrees off, because in the case of MMC really the point is to find bad phases and get as far asway from the as possible. If we get to test extra phases by going slightly non-monotonic then that might be fine. Worst case we would end up at a phases that's slight differnt than the one we wanted, but at least we'd still be quite far away from the a bad phase.

https://github.com/Broadcom/stblinux into next/dt This pull request contains the DT changes for BCM2835 in 4.4. It pulls in clk/clk-bcm2835 (which Stephen Boyd has said would be stable) because the DT changes to enable the clock driver need the driver itself to be present. These changes include the following: - Eric Anholt, moves the bcm2835 clock driver under bcm/ where it belongs with other Broadcom clock providers drivers, defines the binding for new clock driver, adds support for programming the BCM2835 audio domain, adds the DDC I2C controller to Device Tree, and finally migrates the Device Tree to use the new clock driver binding - Lubomir Rintel adds support for the Raspberry Pi Model A+ and B revision 2, and remove the I2S controller which is non-existent on Raspberry Pi Model B - Stefan Wahren adds an uart0 label for referencing the UART adapter * tag 'arm/soc/for-4.4/rpi-dt-v2' of https://github.com/Broadcom/stblinux: ARM: bcm2835: Add the DDC I2C controller to the device tree.
