| * ARCv2: IDU-intc: Use build registers for getting numbers of interruptsYuriy Kolerov2017-02-061-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This enhancement is needed to allow masking all available common interrupts in IDU interrupt controller in boot time since the kernel can discover a number of them from the build register. Also now there is no need to specify in device tree a list of used core interrupts by IDU. E.g. before: idu_intc: idu-interrupt-controller { compatible = "snps,archs-idu-intc"; interrupt-controller; interrupt-parent = <&core_intc>; #interrupt-cells = <2>; interrupts = <24 25 26 27 28 29 30 31>; }; and after: idu_intc: idu-interrupt-controller { compatible = "snps,archs-idu-intc"; interrupt-controller; interrupt-parent = <&core_intc>; #interrupt-cells = <2>; }; Signed-off-by: Yuriy Kolerov <yuriy.kolerov@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I/O pins on Tegra SoCs are grouped into so-called I/O pads. Each such pad can be used to control the common voltage signal level and power state of the pins in the given pad. I/O pads can be powered down even if the system is active, which can save power from that I/O interface. For SoC generations prior to Tegra124 the I/O pad voltage is automatically detected and hence the system software doesn't need to configure it. However, starting with Tegra210 the detection logic has been removed, so explicit control of the I/O pad voltage by system software is required.

The BPMP driver makes use of this to communicate with the Boot and Power Management Processor (BPMP) and uses an additional hardware synchronization primitive from the HSP block to signal availability of new data (doorbell). Firmware running on the BPMP implements a number of services such as the control of clocks and resets within the system, or the ability to ungate or gate power partitions. * tag 'tegra-for-4.10-firmware' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: dt-bindings: firmware: Allow child nodes inside the Tegra BPMP dt-bindings: Add power domains to Tegra BPMP firmware firmware: tegra: Add BPMP support firmware: tegra: Add IVC library dt-bindings: firmware: Add bindings for Tegra BPMP Signed-off-by: Olof Johansson <olof@lixom.net>

It is designed to handle the early stages of the boot process and offload power management tasks (such as clocks, resets, powergates, ...) as well as system control services. Compared to the ARM SCPI, the services provided by BPMP are message- based rather than method-based. The BPMP firmware driver provides the services to transmit data to and receive data from the BPMP. Users can also register a Message ReQuest (MRQ), for which a service routine will be run when a corresponding event is received from the firmware. A set of messages, called the BPMP ABI, are specified for a number of different services provided by the BPMP (such as clocks or resets).

Message channels are used to communicate between processors. They are backed by DRAM or SRAM, so care must be taken to maintain coherence of data. The IVC library maintains memory-based descriptors for the transmission and reception channels as well as the data coherence of the counter and payload.

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 ...

|/ | | | | | | | | | | | | | | | | | | | | The usb controller does not manage correctly the suspend mode for the ehci. In echi mode, there is no way to suspend without any device connected to it. This is why this specific control is added to fix this issue. Since the suspend mode works in ohci mode, this specific control works by suspend the usb controller in ohci mode. This specific control is by setting the SUSPEND_A/B/C fields of SFR_OHCIICR(OHCI Interrupt Configuration Register) in the SFR while the OHCI USB suspend. This set operation must be done before the USB clock disabled, clear operation after the USB clock enabled.
