2019-11-07thermal: amlogic: Add thermal driver to support G12 SoCsGuillaume La Roque
Amlogic G12A and G12B SoCs integrate two thermal sensors with the same design. One is located close to the DDR controller and the other one is located close to the PLLs (between the CPU and GPU). The calibration data for each of the thermal sensors instance is stored in a different location within the AO region. Implement reading the temperature from each thermal sensor. The IP block has more functionality, which may be added to this driver in the future: - chip reset when the temperature exceeds a configurable threshold - up to four interrupts when the temperature has risen above a configurable threshold - up to four interrupts when the temperature has fallen below a configurable threshold Tested-by: Christian Hewitt <christianshewitt@gmail.com> Tested-by: Kevin Hilman <khilman@baylibre.com> Reviewed-by: Amit Kucheria <amit.kucheria@linaro.org> Signed-off-by: Guillaume La Roque <glaroque@baylibre.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20191004090114.30694-3-glaroque@baylibre.com
2019-11-07drivers: thermal: tsens: Add interrupt supportAmit Kucheria
Depending on the IP version, TSENS supports upper, lower and critical threshold interrupts. We only add support for upper and lower threshold interrupts for now. TSENSv2 has an irq [status|clear|mask] bit tuple for each sensor while earlier versions only have a single bit per sensor to denote status and clear. These differences are handled transparently by the interrupt handler. At each interrupt, we reprogram the new upper and lower threshold in the .set_trip callback.

2019-11-07drivers: thermal: tsens: Get rid of id field in tsens_sensorAmit Kucheria
There are two fields - id and hw_id - to track what sensor an action was to performed on. This was because the sensors connected to a TSENS IP might not be contiguous i.e. 1, 2, 4, 5 with 3 being skipped. This causes confusion in the code which uses hw_id sometimes and id other times (tsens_get_temp, tsens_get_trend). Switch to only using the hw_id field to track the physical ID of the sensor. When we iterate through all the sensors connected to an IP block, we use an index i to loop through the list of sensors, and then return the actual hw_id that is registered on that index.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-11-06 This series contains updates to ice driver only. Scott adds ethtool -m support so that we can read eeprom data on SFP/OSFP modules. Anirudh updates the return value to properly reflect when SRIOV is not supported. Md Fahad updates the driver to handle a change in the NVM, where the boot configuration section was moved to the Preserved Field Area (PFA) of the NVM. Paul resolves an issue when DCBx requests non-contiguous TCs, transmit hangs could occur, so configure a default traffic class (TC0) in these cases to prevent traffic hangs. Adds a print statement to notify the user when unsupported modules are inserted. Bruce fixes up the driver unload code flow to ensure we do not clear the interrupt scheme until the reset is complete, otherwise a hardware error may occur. Dave updates the DCB initialization to set is_sw_lldp boolean when the firmware has been detected to be in an untenable state. This will ensure that the firmware is in a known state. Michal saves off the PCI state and I/O BARs address after PCI bus reset so that after the reset, device registers can be read. Also adds a NULL pointer check to prevent a potential kernel panic. Mitch resolves an issue where VF's on PF's other than 0 were not seeing resets by using the per-PF VF ID instead of the absolute VF ID. Krzysztof does some code cleanup to remove a unneeded wrapper and reduces the code complexity. Brett reduces confusion by changing the name of ice_vc_dis_vf() to ice_vc_reset_vf() to better describe what the function is actually doing. v2: dropped patch 3 "ice: Add support for FW recovery mode detection" from the origin al series, while Ani makes changes based on community feedback to implement devlink into the changes. v3: dropped patch 1 "ice: implement set_eeprom functionality" due to a bug found and additional changes will be needed when Ani implements devlink in the driver. ==================== Signed-off-by: David S.

2019-11-06net: stmmac: selftests: Prevent false positives in filter testsJose Abreu
In L2 tests that filter packets by destination MAC address we need to prevent false positives that can occur if we add an address that collides with the existing ones. To fix this, lets manually check if the new address to be added is already present in the NIC and use a different one if so. For Hash filtering this also envolves converting the address to the hash.

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.
