remoteproc: qcom_q6v5_wcss: use optional reset for wcss_q6_bcr_reset

2025-11-29T21:20:23+00:00

The "wcss_q6_bcr_reset" is not used on IPQ8074, and IPQ6018. Use devm_reset_control_get_optional_exclusive() for this reset so that probe() does not fail on platforms where it is not used.

remoteproc: qcom_q6v5_wcss: fix parsing of qcom,halt-regs

2025-11-29T21:19:45+00:00

The "qcom,halt-regs" consists of a phandle reference followed by the three offsets within syscon for halt registers. Thus, we need to request 4 integers from of_property_read_variable_u32_array(), with the halt_reg ofsets at indexes 1, 2, and 3. Offset 0 is the phandle. With MAX_HALT_REG at 3, of_property_read_variable_u32_array() returns -EOVERFLOW, causing .probe() to fail. Increase MAX_HALT_REG to 4, and update the indexes accordingly.

remoteproc: st: Fix indexing of memory-regions

2025-11-27T15:35:19+00:00

The recent transition to use of_reserved_mem_region_to_resource() changes the while loop to a for loop, but the increment of the "index" variable was left behind at the end of the loop, as highlighted by the following error/warning: error: variable 'index' is incremented both in the loop header and in the loop body [-Werror,-Wfor-loop-analysis] Drop the extra increment to avoid skipping over every other memory-region in the loop.
