soc: qcom: apr: Make qcom,protection-domain optional again

2023-01-24T06:24:44Z

commit 599d41fb8ea8bd2a99ca9525dd69405020e43dda upstream. APR should not fail if the service device tree node does not have the qcom,protection-domain property, since this functionality does not exist on older platforms such as MSM8916 and MSM8996. Ignore -EINVAL (returned when the property does not exist) to fix a regression on 6.2-rc1 that prevents audio from working: qcom,apr remoteproc0:smd-edge.apr_audio_svc.-1.-1: Failed to read second value of qcom,protection-domain qcom,apr remoteproc0:smd-edge.apr_audio_svc.-1.-1: Failed to add apr 3 svc Fixes: 6d7860f5750d ("soc: qcom: apr: Add check for idr_alloc and of_property_read_string_index") Signed-off-by: Stephan Gerhold Reviewed-by: Bjorn Andersson Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20221229151648.19839-3-stephan@gerhold.net Signed-off-by: Greg Kroah-Hartman

ARM: ux500: do not directly dereference __iomem

2023-01-07T10:11:38Z

commit 65b0e307a1a9193571db12910f382f84195a3d29 upstream. Sparse reports that calling add_device_randomness() on `uid` is a violation of address spaces. And indeed the next usage uses readl() properly, but that was left out when passing it toadd_device_ randomness(). So instead copy the whole thing to the stack first.

soc: qcom: Select REMAP_MMIO for ICC_BWMON driver

2023-01-07T10:11:36Z

commit a84160fbf4f2c8c5ffa588e19ea8f92eabd7ad17 upstream. ICC_BWMON driver uses REGMAP_MMIO for accessing the hardware registers. So select the dependency in Kconfig.

soc/tegra: cbb: Check firewall before enabling error reporting

[ Upstream commit 2927cf85f4877f417f884919de8e04ab9b362d32 ] To enable error reporting for a fabric to CCPLEX, we need to write its register for enabling error interrupt to CCPLEX during boot and later clear the error status register after error occurs. If a fabric's registers are protected and not accessible from CCPLEX, then accessing the registers will cause CBB firewall error. Add support to check whether write access from CCPLEX to the registers of a fabric is not blocked by it's firewall before enabling error reporting to CCPLEX for that fabric.
