2019-11-07thermal: amlogic: Add thermal driver to support G12 SoCsGuillaume La Roque3-0/+345
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 Kucheria6-63/+669
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 Kucheria4-21/+20
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.

2019-11-02net: fix installing orphaned programsJakub Kicinski1-1/+2
When netdevice with offloaded BPF programs is destroyed the programs are orphaned and removed from the program IDA - their IDs get released (the programs may remain accessible via existing open file descriptors and pinned files). After IDs are released they are set to 0. This confuses dev_change_xdp_fd() because it compares the __dev_xdp_query() result where 0 means no program with prog->aux->id where 0 means orphaned. dev_change_xdp_fd() would have incorrectly returned success even though it had not installed the program. Since drivers already catch this case via bpf_offload_dev_match() let them handle this case. The error message drivers produce in this case ("program loaded for a different device") is in fact correct as the orphaned program must had to be loaded for a different device.

2019-11-02r8169: fix wrong PHY ID issue with RTL8168dpHeiner Kallweit1-0/+4
As reported in [0] at least one RTL8168dp version has problems establishing a link. This chip version has an integrated RTL8211b PHY, however the chip seems to report a wrong PHY ID, resulting in a wrong PHY driver (for Generic Realtek PHY) being loaded. Work around this issue by adding a hook to r8168dp_2_mdio_read() for returning the correct PHY ID.

2019-11-02net: dsa: bcm_sf2: Fix IMP setup for port different than 8Florian Fainelli1-15/+21
Since it became possible for the DSA core to use a CPU port different than 8, our bcm_sf2_imp_setup() function was broken because it assumes that registers are applicable to port 8. In particular, the port's MAC is going to stay disabled, so make sure we clear the RX_DIS and TX_DIS bits if we are not configured for port 8.

2019-11-02inet: stop leaking jiffies on the wireEric Dumazet5-6/+6
Historically linux tried to stick to RFC 791, 1122, 2003 for IPv4 ID field generation. RFC 6864 made clear that no matter how hard we try, we can not ensure unicity of IP ID within maximum lifetime for all datagrams with a given source address/destination address/protocol tuple. Linux uses a per socket inet generator (inet_id), initialized at connection startup with a XOR of 'jiffies' and other fields that appear clear on the wire. Thiemo Nagel pointed that this strategy is a privacy concern as this provides 16 bits of entropy to fingerprint devices. Let's switch to a random starting point, this is just as good as far as RFC 6864 is concerned and does not leak anything critical.

Lyude Paul fixes an issue where a fatal read error occurs when the device is unplugged from the machine. So change the read error into a warn while the device is still present. Manfred Rudigier found that the i350 device was not apart of the "Media Auto Sense" feature, yet the device supports it. So add the missing i350 device to the check and fix an issue where the media auto sense would flip/flop when no cable was connected to the port causing spurious kernel log messages. I fixed an issue where the fix to resolve receive buffer starvation was applied in more than one place in the driver, one being the incorrect location in the i40e driver. Wenwen Wang fixes a potential memory leak in e1000 where allocated memory is not properly cleaned up in one of the error paths. Jonathan Neuschäfer cleans up the driver documentation to be consistent and remove the footnote reference, since the footnote no longer exists in the documentation. Igor Pylypiv cleans up a duplicate clearing of a bit, no need to clear it twice. v2: Fixed alignment issue in patch 3 of the series based on community feedback. ==================== Signed-off-by: David S.
