firmware: qcom_scm: add two scm calls for iommu secure page table

2017-03-28T21:03:21+00:00

Those two new SCM calls are needed from qcom-iommu driver in order to initialize secure iommu page table. Signed-off-by: Stanimir Varbanov Signed-off-by: Rob Clark Signed-off-by: Andy Gross

firmware: qcom_scm: Add set remote state API

2017-01-17T05:45:04+00:00

This patch adds a set remote state SCM API. This will be used by the Venus and GPU subsystems to set state on the remote processors. This work was based on two patch sets by Jordan Crouse and Stanimir Varbanov. Signed-off-by: Andy Gross

firmware: qcom: scm: Mask APQ8064 core clk dependency

2017-01-17T05:07:41+00:00

This patch masks the core clk requirement for the APQ8064. Until the other peripherals correctly describe their clock dependencies or the bus driver is put in place to handle the RPM dependencies, this bit will remain masked. Signed-off-by: Andy Gross

firmware: qcom: scm: Return PTR_ERR when devm_clk_get fails

2016-11-23T17:03:00+00:00

When devm_clk_get fails for core clock, the failure was ignored and the core_clk was explicitly set to NULL so that other remaining clocks can be queried. However, now that we have a cleaner way of expressing the clock dependency, return failure when devm_clk_get fails for core clock.

firmware: qcom: scm: Remove core, iface and bus clocks dependency

2016-11-23T17:02:51+00:00

Core, iface and bus clocks are not required to be voted from SCM driver for some of the Qualcomm chipsets. Remove dependency on these clocks from driver. Suggested-by: Bjorn Andersson Signed-off-by: Sarangdhar Joshi Acked-by: Bjorn Andersson Signed-off-by: Andy Gross

firmware: qcom: scm: Use devm_reset_controller_register()

2016-11-13T05:24:51+00:00

Use devm_reset_controller_register() for the reset controller registration and fixes the memory leak when unload the module. Signed-off-by: Wei Yongjun Signed-off-by: Andy Gross

firmware: qcom_scm: make it explicitly non-modular

2016-08-23T20:46:32+00:00

The Kconfig currently controlling compilation of this code is: drivers/firmware/Kconfig:config QCOM_SCM drivers/firmware/Kconfig: bool ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init was not in use by this code, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.

firmware: qcom: scm: Change initcall to subsys

2016-07-05T21:29:25+00:00

The patch changes the initcall for SCM to use subsys_initcall instead of arch_initcall. This corrects the order so that we don't probe defer when trying to get clks which causes issues later when the spm driver makes calls to qcom_set_warm_boot_addr(). The order became an issue due to the changes to use arch_initcall_sync for of_platform_default_populate_init(). Signed-off-by: Andy Gross

firmware: qcom_scm: Add missing is_available API
