2021-09-19soc: qcom: mdt_loader: Drop PT_LOAD check on hash segmentShawn Guo
PT_LOAD type denotes that the segment should be loaded into the final firmware memory region. Hash segment is not one such, because it's only needed for PAS init and shouldn't be in the final firmware memory region. That's why mdt_phdr_valid() explicitly reject non PT_LOAD segment and hash segment. This actually makes the hash segment type check in qcom_mdt_read_metadata() unnecessary and redundant. For a hash segment, it won't be loaded into firmware memory region anyway, due to the QCOM_MDT_TYPE_HASH check in mdt_phdr_valid(), even if it has a PT_LOAD type for some reason (misusing or abusing?). Some firmware files on Sony phones are such examples, e.g WCNSS firmware of Sony Xperia M4 Aqua phone. The type of hash segment is just PT_LOAD. Drop the unnecessary hash segment type check in qcom_mdt_read_metadata() to fix firmware loading failure on these phones, while hash segment is still kept away from the final firmware memory region.

2021-08-04soc: qcom: smsm: Fix missed interrupts if state changes while maskedStephan Gerhold
The SMSM driver detects interrupt edges by tracking the last state it has seen (and has triggered the interrupt handler for). This works fine, but only if the interrupt does not change state while masked. For example, if an interrupt is unmasked while the state is HIGH, the stored last_value for that interrupt might still be LOW. Then, when the remote processor triggers smsm_intr() we assume that nothing has changed, even though the state might have changed from HIGH to LOW. Attempt to fix this by checking the current remote state before unmasking an IRQ. Use atomic operations to avoid the interrupt handler from interfering with the unmask function. This fixes modem crashes in some edge cases with the BAM-DMUX driver. Specifically, the BAM-DMUX interrupt handler is not called for the HIGH -> LOW smsm state transition if the BAM-DMUX driver is loaded (and therefore unmasks the interrupt) after the modem was already started: qcom-q6v5-mss 4080000.remoteproc: fatal error received: a2_task.c:3188: Assert FALSE failed: A2 DL PER deadlock timer expired waiting for Apps ACK Fixes: c97c4090ff72 ("soc: qcom: smsm: Add driver for Qualcomm SMSM") Signed-off-by: Stephan Gerhold <stephan@gerhold.net> Link: https://lore.kernel.org/r/20210712135703.324748-2-stephan@gerhold.net Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

2021-07-21bus: Make remove callback return voidUwe Kleine-König
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

2021-07-19soc: qcom: aoss: Fix the out of bound usage of cooling_devsManivannan Sadhasivam
In "qmp_cooling_devices_register", the count value is initially QMP_NUM_COOLING_RESOURCES, which is 2. Based on the initial count value, the memory for cooling_devs is allocated. Then while calling the "qmp_cooling_device_add" function, count value is post-incremented for each child node. This makes the out of bound access to the cooling_dev array. Fix it by passing the QMP_NUM_COOLING_RESOURCES definition to devm_kzalloc() and initializing the count to 0. While at it, let's also free the memory allocated to cooling_dev if no cooling device is found in DT and during unroll phase.

rpmhpd_aggregate_corner() takes a corner as parameter, but in rpmhpd_power_off() the code requests the level of the first corner instead. In all (known) current cases the first corner has level 0, so this change should be a nop, but in case that there's a power domain with a non-zero lowest level this makes sure that rpmhpd_power_off() actually requests the lowest level - which is the closest to "power off" we can get.

Given that no validation of how much data the firmware loader read in for a given segment truncated segment files would best case result in a hash verification failure, without any indication of what went wrong.

2021-03-26soc: qcom-geni-se: Cleanup the code to remove proxy votesRoja Rani Yarubandi
This reverts commit 048eb908a1f2 ("soc: qcom-geni-se: Add interconnect support to fix earlycon crash") ICC core and platforms drivers supports sync_state feature, which ensures that the default ICC BW votes from the bootloader is not removed until all it's consumers are probes. The proxy votes were needed in case other QUP child drivers I2C, SPI probes before UART, they can turn off the QUP-CORE clock which is shared resources for all QUP driver, this causes unclocked access to HW from earlycon. Given above support from ICC there is no longer need to maintain proxy votes on QUP-CORE ICC node from QUP wrapper driver for early console usecase, the default votes won't be removed until real console is probed.

Currently, GENI devices like i2c-qcom-geni fails to probe in ACPI boot, if interconnect support is enabled. That's because interconnect driver only supports DT right now. As interconnect is not necessarily required for basic function of GENI devices, let's shield geni_icc_get() call, and then all other ICC calls become nop due to NULL icc_path, so that GENI devices keep working for ACPI boot.
