2019-11-06ice: Rename VF function ice_vc_dis_vf to match its behaviorBrett Creeley
ice_vc_dis_vf() tells iavf that it's going to perform a reset and then performs a software reset. This is misleading based on the function name because the VF does not get disabled. So fix this by changing the name to ice_vc_reset_vf().

2019-11-06ice: write register with correct offsetMitch Williams
The VF_MBX_ARQLEN register array is per-PF, not global, so we should not use the absolute VF ID as an index. Instead, use the per-PF VF ID. This fixes an issue with VFs on PFs other than 0 not seeing reset.

2019-11-06hwmon: (ina3221) Add summation feature supportNicolin Chen
This patch implements the summation feature of INA3221, mainly the SCC (enabling) and SF (warning flag) bits of MASK_ENABLE register, INA3221_SHUNT_SUM (summation of shunt voltages) register, and the INA3221_CRIT_SUM (its critical alert setting) register. Although the summation feature allows user to select which channels to be added to the result, as an initial support, this patch simply selects all channels by default, with one only condition: all shunt resistor values need to be the same. This is because the summation of current channels can be only accurately calculated, using shunt voltage sum register, if all shunt resistors are equivalent.

2019-11-06drm/amdgpu: add dummy read by engines for some GCVM status registers in gfx10changzhu
The GRBM register interface is now capable of bursting 1 cycle per register wr->wr, wr->rd much faster than previous muticycle per transaction done interface. This has caused a problem where status registers requiring HW to update have a 1 cycle delay, due to the register update having to go through GRBM. For cp ucode, it has realized dummy read in cp firmware.It covers the use of WAIT_REG_MEM operation 1 case only.So it needs to call gfx_v10_0_wait_reg_mem in gfx10. Besides it also needs to add warning to update firmware in case firmware is too old to have function to realize dummy read in cp firmware. For sdma ucode, it hasn't realized dummy read in sdma firmware. sdma is moved to gfxhub in gfx10. So it needs to add dummy read in driver between amdgpu_ring_emit_wreg and amdgpu_ring_emit_reg_wait for sdma_v5_0.

2019-11-06drm/amdgpu: disallow direct upload save restore list from gfx driverHawking Zhang
Direct uploading save/restore list via mmio register writes breaks the security policy. Instead, the driver should pass s&r list to psp. For all the ASICs that use rlc v2_1 headers, the driver actually upload s&r list twice, in non-psp ucode front door loading phase and gfx pg initialization phase. The latter is not allowed. VG12 is the only exception where the driver still keeps legacy approach for S&R list uploading. In theory, this can be elimnated if we have valid srcntl ucode for VG12.
