soc: qcom/spm: shut up uninitialized variable warning

2016-09-24T08:07:42Z

commit 00affcac69c7aae6c2cfcbc71f724e1c16d0b445 upstream. gcc warns about the 'found' variable possibly being used uninitialized: drivers/soc/qcom/spm.c: In function 'spm_dev_probe': drivers/soc/qcom/spm.c:305:5: error: 'found' may be used uninitialized in this function [-Werror=maybe-uninitialized] However, the code is correct because we know that there is always at least one online CPU. This initializes the 'found' variable to zero before the loop so the compiler knows it does not have to warn about it. Signed-off-by: Arnd Bergmann Signed-off-by: Greg Kroah-Hartman

soc: rockchip: power-domain: fix err handle while probing

2016-05-11T09:21:11Z

commit 1d961f11a108af9f7fbe89cc950a8d16ddbdbb28 upstream. If we fail to probe the driver, we should not directly break from the for_each_available_child_of_node since it calls of_node_get while iterating. This patch add of_node_put to fix the unbalanced call pair.

soc: ti: knav_qmss_queue: Fix linking RAM setup for queue managers

2015-11-23T18:36:27Z

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. Signed-off-by: Michal Morawiec Signed-off-by: Santosh Shilimkar

soc: ti: use request_firmware_direct() as acc firmware is optional

2015-11-23T18:32:44Z

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.

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 ...

soc: qcom: smd-rpm: Correct size of outgoing message

With the removal of VLAIS the size was incorrectly changed to only cover the headers of the packet, resulting in "empty" requests being sent to the RPM.
