* gpu: nvgpu: cleanup return types for MISRA 10.3Philip Elcan2018-09-07
| | | | | | | | | | | | | | | This is a big cleanup of return types across a number of modules in the nvgpu driver. Many functions were returning u32 but using negative return codes. This is a MISRA 10.3 violation by assigning signed values to a u32.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Added support for single rail multi step volt policy & below are the list of define & struct added/updated to support same. CTRL_VOLT_POLICY_TYPE_SINGLE_RAIL_MULTI_STEP 0x04, NV_VBIOS_VOLTAGE_POLICY_1X_ENTRY_TYPE_SINGLE_RAIL_MULTI_STEP 0x04, Updated struct vbios_voltage_policy_table_1x_entry, struct nv_pmu_volt_volt_policy_sr_multi_step_boardobj_set, this holds members which help to config single rail multi step like delay between switch step, ramp up & ramp down step size in uv. - Added case to support SINGLE_RAIL_MULTI_STEP in volt_volt_policy_construct() based on boardobj type. - Added case to support SINGLE_RAIL_MULTI_STEP in volt_get_volt_policy_table() to read data from VBIOS table vbios_voltage_policy_table_1x_entry & extract to voltage_policy_single_rail_multi_step. - Added methods to forward single rail multi step data to PMU using below methods by assigning data read from VBIOS voltage_policy_single_rail_multi_step to nv_pmu_volt_volt_policy_sr_multi_step_boardobj_set interface. volt_construct_volt_policy_single_rail_multi_step() volt_policy_pmu_data_init_sr_multi_step() volt_policy_pmu_data_init_single_rail() construct_volt_policy_single_rail() Change-Id: I17bc8c320777191611365ee63274c38ffe5ecbf7 Signed-off-by: Mahantesh Kumbar <mkumbar@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1660687 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: svc-mobile-coverity <svc-mobile-coverity@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Vijayakumar Subbu <vsubbu@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

- changes to read voltage tables from VBIOS & create boardobj then send to pmu - Rail, Device & Policy objects are read from VBIOS & created boardobjs - RPC support to load, Set & get voltage.
