* remoteproc: q6v5-mss: Active powerdomain for SDM845Bjorn Andersson2019-01-301-2/+29
| | | | | | | | | | The SDM845 MSS needs the load_state powerdomain voted for during the duration of the MSS being powered on, to let the AOSS know that it may not perform certain power save measures. So vote for this. Tested-by: Sibi Sankar <sibis@codeaurora.org> Reviewed-by: Sibi Sankar <sibis@codeaurora.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
* remoteproc: q6v5-mss: Vote for rpmh power domainsRajendra Nayak2019-01-301-5/+114
| | | | | | | | | | | | | With rpmh ARC resources being modelled as power domains with performance state, we need to proxy vote on these for SDM845. Add support to vote on multiple of them, now that genpd supports associating mutliple power domains to a device.

| | | | | | | | | | | Sometimes that rmtfs userspace module is not brought up fast enough and the modem crashes. disabling automated boot in the driver and triggering the boot from user-space sovles the problem.

* remoteproc: qcom: q6v5-mss: Refactor mba load/unload sequenceSibi Sankar2018-10-191-138/+170
| | | | | | | | | | | | | | | Refactor re-useable parts of mba load/unload sequence into mba_load and mba_reclaim respectively. This is done in order to prevent code duplication for modem coredump, which requires the mba to be loaded before dumping the segments. The following changes in functionality are intended: * Add software bypass to avoid high MX current in mpss error path. * Remove the proxy votes of clk/regs only after the active/reset clks/regs. * Reclaim MBA memory after mpss_load failure in mba_reclaim func. * Set/Unset the dump_mba_loaded flag on mba_load/mba_reclaim respectively.
