| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Configure linking RAM for both queue managers also in case when only linking RAM 0 is specified in device tree. Currently hwqueue driver configures linking RAM(s) to be used cooperatively by the QMs (shared mode). Therefore if both queue managers are used then both must be configured with exactly the same linking RAM info (base address and size) independent of the number of linking RAM(s) specified in the device tree. For proper operation only one linking RAM is required and in most cases this can be internal one as long as it is able to handle the number of descriptors used in the system. Current driver code however skips configuration of second queue manager if second linking RAM is not specified. If the configuration for the QM2 is missing there will be a crash when it tries to push/pop descriptors from its queues.

| | | | | | | | | | | | | | | | | | | | | | When firmware image for PDSP firmware is absent in the file system the kernel boot with ramfs/nfs is stuck for 60 seconds being the the default timeout. request_firmware_direct() is to take care of such optional firmware loading and hence replace the call in the driver with this API.

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 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SMEM is a software construct built on top of a DDR reserved region and sometimes a device memory region called RPM message ram. Having the RPM message ram in the smem DT node's reg property leads to the smem node being located in different places depending on if the message ram is being used or not. Let's add a qcom specific property, qcom,rpm-msg-ram, and point to the device memory from the SMEM node via a phandle. As SMEM is a software construct, it really needs to reside at the root of the DT regardless of whether it's using the message ram or not.

After setting the register, PMU would enter the Low Power mode.

This fixes the corner-case where the pmic is initialized by the bootloader, but not the pmic watchdog. Add support for active wakeup to the scpsys. This allows to keep the power of a scpsys domain during suspend state. With version v4.3 new subsystem clocks are added to the clock dirver. In late init the kernel turns off all unused clocks. This can provoke a hang if the kernel tries to access the venc and venc_lt power domain registers. Add the necessary parent clocks for this power domains to the scpsys so that no random hang happens. The bootloader of mt6589, mt8135 and mt1827 does not turn on the arm-arch-timer. As there is no opensource bootloader in the near future for this architectures we enable the arch timer at kernel boot. We need the arch timer for SMP boot. Add support for SMP on mt6589, mt8127 and mt8135. * tag 'v4.3-next-soc' of https://github.com/mbgg/linux-mediatek: ARM: mediatek: add smp bringup code ARM: mediatek: enable gpt6 on boot up to make arch timer working soc: mediatek: Fix random hang up issue while kernel init soc: mediatek: add scpsys support active_wakeup soc: mediatek: Move the initial setting of pmic wrap interrupt before requesting irq.

Accessing MT8173 VENC registers needs two top clocks, mm_sel and venc_sel. Accessing VENC_LT registers needs mm_sel and venclt_sel. So we need to keep these clocks on before accessing their registers. This patch keeps venc_sel / venclt_sel clock on when VENC / VENC_LT's power is on, to prevent system hang up while accessing its registeres.

This is not scalable as user has to change the DTS if they need upgrade to a new firmware. Instead, add the firmware file name in the driver itself. As long as there is no API change, new firmware upgrade is easy and require no driver change. User is expected to copy the firmware image to the file system and add a sym link to the new firmware for doing an upgrade. Driver add a array of firmware file names to search for the available firmware blobs. This scheme also prepare the driver for future changes to API if ever happens. In such case it is assumed that driver needs to change to accommodate the new firmware and new firmware file name will get added to the array. Also update the DT document to remove the firmware attribute and add description about firmware in the driver documentation.

It tends to gather drivers that need SoC modification or dependencies such that they have to (also) go in through our tree. For this release, we have merged in part of the reset controller tree (with handshake that the parts we have merged in will remain stable), as well as dependencies on a few clock branches. In general, new items here are: - Qualcomm driver for SMM/SMD, which is how they communicate with the coprocessors on (some) of their platforms - memory controller work for ARM's PL172 memory controller - reset drivers for various platforms - PMU power domain support for Marvell platforms - Tegra support for T132/T210 SoCs: PMC, fuse, memory controller per-SoC support" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (49 commits) ARM: tegra: cpuidle: implement cpuidle_state.enter_freeze() ARM: tegra: Disable cpuidle if PSCI is available soc/tegra: pmc: Use existing pclk reference soc/tegra: pmc: Remove unnecessary return statement soc: tegra: Remove redundant $(CONFIG_ARCH_TEGRA) in Makefile memory: tegra: Add Tegra210 support memory: tegra: Add support for a variable-size client ID bitfield clk: shmobile: rz: Add CPG/MSTP Clock Domain support clk: shmobile: rcar-gen2: Add CPG/MSTP Clock Domain support clk: shmobile: r8a7779: Add CPG/MSTP Clock Domain support clk: shmobile: r8a7778: Add CPG/MSTP Clock Domain support clk: shmobile: Add CPG/MSTP Clock Domain support ARM: dove: create a proper PMU driver for power domains, PMU IRQs and resets reset: reset-zynq: Adding support for Xilinx Zynq reset controller. docs: dts: Added documentation for Xilinx Zynq Reset Controller bindings.
