soc: Tighten some soc driver dependencies

2025-08-14T16:59:16Z

The Qualcomm Snapdragon "SoC" driver cannot build without access to some ARM64 specific functionality. Express that requirements in Kconfig as well. Reviewed-by: Casey Connolly Signed-off-by: Tom Rini

soc: qcom: rpmh-rsc: add back __tcs_set_trigger() for SM8550/SM8650

2024-09-06T08:47:46Z

The TCS writes has no effect after the removal of the __tcs_set_trigger() call, obviously it seems the RSC version 3 requires it to complete the transactions.

soc: qcom: cmd-db: map cmd-db region

2024-09-06T08:47:46Z

On at least SM8650 this region might not be included in the memory map. Use the new mmu_map_region() helper to map it during bind(). Reviewed-by: Neil Armstrong Signed-off-by: Caleb Connolly

soc: qcom: cmd-db: use strncmp() instead of memcmp()

2024-09-06T08:47:46Z

memcmp() can cause aborts on some platforms and generally seems to be the wrong approach here. Use strncmp() instead which is more correct. Reviewed-by: Neil Armstrong Signed-off-by: Caleb Connolly

soc: qcom: add build infrastructure

2024-07-25T23:28:11Z

Add Kconfig / Makefiles to build rpmh and cmd-db drivers. Reviewed-by: Neil Armstrong Signed-off-by: Caleb Connolly

soc: qcom: rpmh: U-Boot API changes

2024-07-25T23:28:11Z

Fix build errors, add some debug logging. Acked-by: Sumit Garg Signed-off-by: Caleb Connolly

soc: qcom: rpmh: drop unused functions

2024-07-25T23:28:11Z

A lot of the features in here are only relevant when running multi-threaded with interrupts. Drop everything except what we need to run single-threaded with a single TCS (which is all the rpmh-rsc framework in U-Boot supports). Keep rpmh_write_async() for simplicity and make it wrap the regular rpmh_write(). Acked-by: Sumit Garg Signed-off-by: Caleb Connolly

soc: qcom: rpmh: adjust headers for U-Boot

2024-07-25T23:28:11Z

Drop unused/unsupported Linux headers and add dm/device.h for U-Boot. Acked-by: Sumit Garg Signed-off-by: Caleb Connolly

soc: qcom: rpmh-rsc: remaining U-Boot API changes

2024-07-25T23:28:11Z

Minor adjustments to fix building with U-Boot and work correctly as a synchronous driver without interrupts. RPMh is fast enough that we can get away with just firing off requests and assuming they complete. U-Boot behaviour changes are annotated with a "U-Boot:" comment.
