git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk framework updates from Stephen Boyd: "The core clk framework changes are small again. They're mostly minor fixes that weren't causing enough problems (or any problems when we're just clarifying things) to warrant sending outside the merge window. The majority of changes are in drivers for various SoCs. Full details are in the logs, but here's the summary. Core: - Better support for DeviceTree overlays with the addition of the CLK_OF_DECLARE_DRIVER macro. Now we won't probe a clk driver for a device node that matched during of_clk_init(), unless the driver uses CLK_OF_DECLARE_DRIVER instead of CLK_OF_DECLARE. This allows overlays to work cleanly for drivers that must probe before the device model is ready, and also after it's ready when an overlay is loaded. - Clarification in the code around how clk_hw pointers are returned from of clk providers - Proper migration of prepare/enable counts to parents when the clk tree is constructed New Drivers: - Socionext's UniPhier SoCs - Loongson1C - ZTE ZX296718 - Qualcomm MDM9615 - Amlogic GXBB AO clocks and resets - Broadcom BCM53573 ILP - Maxim MAX77620 Updates: - Four Allwinner SoCs are migrated to the new style clk driver (A31, A31s, A23 and A33) - Exynos 5xxx audio and DRAM clks - Loongson1B AC97, DMA and NAND clks - Rockchip DDR clks and rk3399 driver tweaks - Renesas R-Car M3-W (r8a7796) SoC SDHI interface and Watchdog timer clks - Renasas R-Car H3 and M3-W CMT clks and RAVB+Thermal clks for M3-W - Amlogic GXBB MMC gate clks - at91 sama5d4 sckc - Removal of STiH415 and STiH416 clk support as the SoC is being removed - Rework of STiH4xx clk support for new style bindings - Continuation of driver migration to clk_hw based registration APIs - xgene PMD support - bcm2835 critical clk markings - ARM versatile ICST" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (199 commits) CLK: Add Loongson1C clock support clk: Loongson1: Make use of GENMASK clk: Loongson1: Update clocks of Loongson1B clk: Loongson1: Refactor Loongson1 clock clk: change the type of clk_hw_onecell_data.num to unsigned int clk: zx296718: register driver earlier with core_initcall clk: mvebu: dynamically allocate resources in Armada CP110 system controller clk: mvebu: fix setting unwanted flags in CP110 gate clock clk: nxp: clk-lpc32xx: Unmap region obtained by of_iomap clk: mediatek: clk-mt8173: Unmap region obtained by of_iomap clk: sunxi-ng: Fix reset offset for the A23 and A33 clk: at91: sckc: optimize boot time clk: at91: Add sama5d4 sckc support clk: at91: move slow clock controller clocks to sckc.c clk: imx6: initialize GPU clocks clk: imx6: fix i.MX6DL clock tree to reflect reality clk: imx53: Add clocks configuration clk: uniphier: add clock data for UniPhier SoCs clk: uniphier: add core support code for UniPhier clock driver clk: bcm: Add driver for BCM53573 ILP clock ...

2016-10-04PCI: rockchip: Fix wrong transmitted FTS countShawn Lin1-0/+10
If the expected number of FTS aren't received by RC when exiting from L0s, the LTSSM will fall into recover state, which means it will need to send TS for retraining which makes the latency of exiting from L0s a little longer than expected. This issue is caused by an incorrect reset value of FTS count on PLC1 register (offset 0x4). The expected value for Gen1/2 should be more than 240 and we may leave a little margin here. Fix this before starting Gen1 training which will make TS1 contain the correct FTS count. Signed-off-by: Shawn Lin <[email protected]> Signed-off-by: Bjorn Helgaas <[email protected]>
2016-10-04PCI: rockchip: Improve the deassert sequence of four reset pinsShawn Lin1-6/+10
Per TRM, we need to deassert the four reset pins simultaneously. Currently the reset framework doesn't support that so we did it one by one. It seems no side effect found but it does impact the state machine of controller, so sometimes the change speed bit is not set when sending training sequence from recover state. After the silicon RTL review from SoC guys, we don't need to do the sequence recommended by TRM, and could just move the deassert of mgmt_sticky_rst to the first place.

2016-10-04PCI: rockchip: Increase the Max Credit update intervalRajat Jain1-0/+17
Increase the likelihood of link state to automatically go to L1 and save some power. The default credit update interval of 7.5 us results in the rootport sending UpdateFC-P and UpdateFC-NP packets too often, thus resulting in the link never going to L1, and always staying in L0/L0s. The value 24 us was chosen after some experiments and peeking over the PCIe bus to see that we do enter L1 substate when there is not enough traffic on the PCIe bus.

2016-10-04mfd: ab8500-debugfs: Prevent initialised field from being over-writtenLee Jones2-29/+23
Due to the lack of parity in the way array fields have been named/ numbered, a mistake was made where more debug fields were declared than actually existed. In doing so, 2 fields were added, which although unclear, were already declared in the array. The result was that the latter declarations trashed the former ones. This patch places the array back in the correct order and removes the offending NULL entries. While we're at it, let's ensure this doesn't happen again by naming each field properly and add a new *_LAST define to describe how many fields there should be.

Since module_init was not in use by this code, the init ordering remains unchanged with this commit. We replace module.h with init.h and delete an unused moduleparam.h include. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

2016-10-04mfd: as3722: Convert MFD_AS3722 from bool to tristatePaul Gortmaker1-1/+1
The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_AS3722 drivers/mfd/Kconfig: bool "ams AS3722 Power Management IC" ...meaning that it currently is not being built as a module by anyone. In response to an earlier patch set suggesting removal of the unused modular code, Laxman suggested that this driver be instead moved to tristate. We do that here, and confirm it can build and modpost as a tristate. However there remains to be runtime testing in order to ensure this change is 100% functional for "=m".

Add support for handling IRQs: power button, AC and USB power state changes. Mask and interrupt bits are shared within one register, which prevents us to use regmap_irq implementation. New irq_domain is created in order to add interrupt handling for each tps65217's subsystem. IRQ resources have been added for charger subsystem to be able to notify about AC and USB state changes.

2016-10-04mfd: ucb1x00: Remove NO_IRQ checkArnd Bergmann1-1/+1
probe_irq_off() returns '0' on failure, not NO_IRQ, so the check in this driver is clearly wrong. This replaces it with the regular '!irq' check used in other drivers. The sa1100 platform that this driver is used on originally numbered all its interrupts starting at '0', which would have conflicted with this change, but as of commit 18f3aec ("ARM: 8230/1: sa1100: shift IRQs by one"), this is not a problem any more.

2016-10-04mfd: arizona: Use suspend_noirq inplace of suspend_lateCharles Keepax1-6/+4
As runtime PM doesn't function whilst processing system suspend/resume operations and the Arizona IRQ handlers need runtime PM to function we must disable IRQs during these operations. Whilst this is already done in the driver we are using suspend/suspend_late and resume/resume_noirq to do so which has two problems. Firstly, as suspend_late is before suspend_noirq that means we still have a small window where an IRQ can cause issues. Secondly, if another suspend_late handler fails after ours has run then (as resume_noirq will not run) we will make unbalanced calls to enable_irq. This is all simply fixed by using the suspend_noirq callback rather than suspend_late. Whilst we are doing this tidy the code up a little, and use the appropriate helper macros.

2016-10-04mfd: arizona: Add sensible return value to some error pathsCharles Keepax1-1/+4
There are some cases in arizona_dev_init, such as where we don't recognise the chip ID, in which we head to the error path without setting a sensible error code in ret. This would lead to the chip silently failing probe, as it would still return 0. Fix this up by adding appropriate sets of the return value. Whilst adding these update the existing paths that do return an error when the chip is not recognised to use ENODEV, which seems like a better fit.

This is a minimal driver which prepares resources for IP blocks like I2S, audio DMA and UART and exposes a regmap for the Top block registers.
