firmware: qcom_scm: drop redandant of_platform_populate

2017-12-20T21:38:34Z

Now that of_platform_default_populate_init() takes care of populating all the devices under the /firmware/ node, this patch removes the redandant call to of_platform_populate here.

firmware: scm: Add new SCM call API for switching memory ownership

2017-10-31T01:37:07Z

Two different processors on a SOC need to switch memory ownership during load/unload. To enable this, second level memory map table need to be updated, which is done by secure layer. This patch adds the interface for making secure monitor call for memory ownership switching request.

firmware: qcom: scm: Expose download-mode control

2017-10-12T04:48:27Z

In order to aid post-mortem debugging the Qualcomm platforms provide a "memory download mode", where the boot loader will provide an interface for custom tools to "download" the content of RAM to a host machine. The mode is triggered by writing a magic value somewhere in RAM, that is read in the boot code path after a warm-restart. Two mechanism for setting this magic value are supported in modern platforms; a direct SCM call to enable the mode or through a secure io write of a magic value. In order for a normal reboot not to trigger "download mode" the magic must be cleared during a clean reboot. Download mode has to be enabled by including qcom_scm.download_mode=1 on the command line.

firmware: qcom: scm: Mask APQ8064 core clk dependency

2017-01-17T05:07:41Z

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

2016-11-23T17:03:00Z

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.
