soc/qcom: rpmh: correctly wait for TCS flush 2026-01-14T15:25:09+00:00 Casey Connolly casey.connolly@linaro.org 2026-01-08T20:28:45+00:00 5942ad0ddb54e7042d2f465d563779da4e42bc47 Several bugs were discovered in the rpmh-rsc driver which collectively meant we were never actually waiting for the TCS to flush, these were likely missed because U-Boot runs single threaded and the RPMh had typically processed the single command we sent by the time we went to send the next one. However a future patch will implement rpmh read support which requires us to properly wait for the RPMh command response so we can return the value. Fix these issues so we correctly ensure the TCS is done before returning.

dm: core: Default to using DEVRES outside of xPL 2026-01-09T15:08:14+00:00 Tom Rini trini@konsulko.com 2025-12-27T22:37:11+00:00 217cf656e249f698d390a7d8eaf255eb1a6c0230 The devm alloc functions that we have may follow the Linux kernel model where allocations are (almost always) automatically free()'d. However, quite often we don't enable, in full U-Boot, the tracking and free()'ing functionality. This in turn leads to memory leaks because the driver author expects that since the functions have the same name as in the Linux Kernel they have the same behavior. In turn we then get functionally correct commits such as commit 00e1fed93c8c ("firmware: ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually add these calls. Rather than manually tracking allocations and implementing free()s, rework things so that we follow expectations by enabling the DEVRES functionality (outside of xPL phases). This turns DEVRES from a prompted symbol to a symbol that must be select'd, and we now remove our non-managed alloc/free functions from outside of xPL builds.
