The device link device's name was of the form: <supplier-dev-name>--<consumer-dev-name> This can cause name collision as reported here [1] as device names are not globally unique. Since device names have to be unique within the bus/class, add the bus/class name as a prefix to the device names used to construct the device link device name.

2021-01-21driver core: Extend device_is_dependent()Rafael J. Wysocki1-1/+16
If the device passed as the target (second argument) to device_is_dependent() is not completely registered (that is, it has been initialized, but not added yet), but the parent pointer of it is set, it may be missing from the list of the parent's children and device_for_each_child() called by device_is_dependent() cannot be relied on to catch that dependency. For this reason, modify device_is_dependent() to check the ancestors of the target device by following its parent pointer in addition to the device_for_each_child() walk.

The number of hdmi_rdma_channels determines the size of the regmap via this code in sound/soc/qcom/lpass-cpu.c: lpass_hdmi_regmap_config.max_register = LPAIF_HDMI_RDMAPER_REG(variant, variant->hdmi_rdma_channels); According to debugfs the size of the regmap is 0x68010 but according to the DTS file posted in [1] the size is only 0x68000 (see the first reg property of the lpass_cpu node). Let's change the number of channels to be 3 instead of 4 so the math works out to have a max register of 0x67010, nicely fitting inside of the region size of 0x68000. Note: I tried to bump up the size of the register region to the next page to include the 0x68010 register but then the tail command caused SErrors with an async abort, implying that the register region doesn't exist or it isn't clocked because the bus is telling us that the register read failed. I reduce the number of channels and played audio through the HDMI channel and it kept working so I think this is correct.

2021-01-21x86/fpu: Add kernel_fpu_begin_mask() to selectively initialize stateAndy Lutomirski2-6/+18
Currently, requesting kernel FPU access doesn't distinguish which parts of the extended ("FPU") state are needed. This is nice for simplicity, but there are a few cases in which it's suboptimal: - The vast majority of in-kernel FPU users want XMM/YMM/ZMM state but do not use legacy 387 state. These users want MXCSR initialized but don't care about the FPU control word. Skipping FNINIT would save time. (Empirically, FNINIT is several times slower than LDMXCSR.) - Code that wants MMX doesn't want or need MXCSR initialized. _mmx_memcpy(), for example, can run before CR4.OSFXSR gets set, and initializing MXCSR will fail because LDMXCSR generates an #UD when the aforementioned CR4 bit is not set. - Any future in-kernel users of XFD (eXtended Feature Disable)-capable dynamic states will need special handling. Add a more specific API that allows callers to specify exactly what they want.

2021-01-20net: dsa: microchip: Adjust reset release timing to match reference reset ↵Marek Vasut1-1/+1
circuit KSZ8794CNX datasheet section 8.0 RESET CIRCUIT describes recommended circuit for interfacing with CPU/FPGA reset consisting of 10k pullup resistor and 10uF capacitor to ground. This circuit takes ~100 ms to rise enough to release the reset. For maximum supply voltage VDDIO=3.3V VIH=2.0V R=10kR C=10uF that is VDDIO - VIH t = R * C * -ln( ------------- ) = 10000*0.00001*-(-0.93)=0.093 s VDDIO so we need ~95 ms for the reset to really de-assert, and then the original 100us for the switch itself to come out of reset. Simply msleep() for 100 ms which fits the constraint with a bit of extra space.

2021-01-20net: dsa: microchip: ksz8795: Fix KSZ8794 port map againMarek Vasut2-11/+21
The KSZ8795 switch has 4 external ports {0,1,2,3} and 1 CPU port {4}, so does the KSZ8765. The KSZ8794 seems to be repackaged KSZ8795 with different ID and port 3 not routed out, however the port 3 registers are present in the silicon, so the KSZ8794 switch has 3 external ports {0,1,2} and 1 CPU port {4}. Currently the driver always uses the last port as CPU port, on KSZ8795/KSZ8765 that is port 4 and that is OK, but on KSZ8794 that is port 3 and that is not OK, as it must also be port 4. This patch adjusts the driver such that it always registers a switch with 5 ports total (4 external ports, 1 CPU port), always sets the CPU port to switch port 4, and then configures the external port mask according to the switch model -- 3 ports for KSZ8794 and 4 for KSZ8795/KSZ8765.
