2020-09-24gpio: aspeed: fix ast2600 bank propertiesTao Ren
GPIO_U is mapped to the least significant byte of input/output mask, and the byte in "output" mask should be 0 because GPIO_U is input only. All the other bits need to be 1 because GPIO_V/W/X support both input and output modes. Similarly, GPIO_Y/Z are mapped to the 2 least significant bytes, and the according bits need to be 1 because GPIO_Y/Z support both input and output modes.

2020-09-24gpio/aspeed-sgpio: don't enable all interrupts by defaultJeremy Kerr
Currently, the IRQ setup for the SGPIO driver enables all interrupts in dual-edge trigger mode. Since the default handler is handle_bad_irq, any state change on input GPIOs will trigger bad IRQ warnings. This change applies sensible IRQ defaults: single-edge trigger, and all IRQs disabled.

2020-09-24gpio/aspeed-sgpio: enable access to all 80 input & output sgpiosJeremy Kerr
Currently, the aspeed-sgpio driver exposes up to 80 GPIO lines, corresponding to the 80 status bits available in hardware. Each of these lines can be configured as either an input or an output. However, each of these GPIOs is actually an input *and* an output; we actually have 80 inputs plus 80 outputs. This change expands the maximum number of GPIOs to 160; the lower half of this range are the input-only GPIOs, the upper half are the outputs. We fix the GPIO directions to correspond to this mapping. This also fixes a bug when setting GPIOs - we were reading from the input register, making it impossible to set more than one output GPIO.

A struct device is a dynamic structure, with reference counting. "Tricking" the kernel to make a dynamic structure static, by working around the driver core release detection logic, is not nice. Because of this, this code has been used as an example for others on "how to do things", which is just about the worst thing possible to have happen.

2020-09-24platform/x86: intel-vbtn: Fix SW_TABLET_MODE always reporting 1 on the HP ↵Hans de Goede
Pavilion 11 x360 Commit cfae58ed681c ("platform/x86: intel-vbtn: Only blacklist SW_TABLET_MODE on the 9 / "Laptop" chasis-type") restored SW_TABLET_MODE reporting on the HP stream x360 11 series on which it was previously broken by commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet mode switch on 2-in-1's"). It turns out that enabling SW_TABLET_MODE reporting on devices with a chassis-type of 10 ("Notebook") causes SW_TABLET_MODE to always report 1 at boot on the HP Pavilion 11 x360, which causes libinput to disable the kbd and touchpad. The HP Pavilion 11 x360's ACPI VGBS method sets bit 4 instead of bit 6 when NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT collection shows only one other model, the Medion E1239T ever setting bit 4 and it always sets this together with bit 6. So lets treat bit 4 as a second bit which when set indicates the device not being in tablet-mode, as we already do for bit 6. While at it also prefix all VGBS constant defines with "VGBS_".

2020-09-24platform/x86: asus-nb-wmi: Revert "Do not load on Asus T100TA and T200TA"Hans de Goede
The WMI INIT method on for some reason turns on the camera LED on these 2-in-1s, without the WMI interface allowing further control over the LED. To fix this commit b5f7311d3a2e ("platform/x86: asus-nb-wmi: Do not load on Asus T100TA and T200TA") added a blacklist with these 2 models on it since the WMI driver did not add any extra functionality to these models. Recently I've been working on making more 2-in-1 models report their tablet-mode (SW_TABLET_MODE) to userspace; and I've found that these 2 Asus models report this through WMI. This commit reverts the adding of the blacklist, so that the Asus WMI driver can be used on these models to report their tablet-mode. I have another patch fixing the LED issue in a different manner. Note this is the second time the we revert the adding of the asus_nb_wmi_blacklist. It was reverted before in commit: aab9e7896ec9 ("platform/x86: asus-nb-wmi: Revert "Do not load on Asus T100TA and T200TA")" But some how (accidentally re-applying of the patch?) it got re-added again in commit 3bd12da7f50b ("platform/x86: asus-nb-wmi: Do not load on Asus T100TA and T200TA"), so now we need to revert it again.

2020-09-23net: dsa: b53: Configure VLANs while not filteringFlorian Fainelli
Update the B53 driver to support VLANs while not filtering. This requires us to enable VLAN globally within the switch upon driver initial configuration (dev->vlan_enabled). We also need to remove the code that dealt with PVID re-configuration in b53_vlan_filtering() since that function worked under the assumption that it would only be called to make a bridge VLAN filtering, or not filtering, and we would attempt to move the port's PVID accordingly. Now that VLANs are programmed all the time, even in the case of a non-VLAN filtering bridge, we would be programming a default_pvid for the bridged switch ports. We need the DSA receive path to pop the VLAN tag if it is the bridge's default_pvid because the CPU port is always programmed tagged in the programmed VLANs. In order to do so we utilize the dsa_untag_bridge_pvid() helper introduced in the commit before within net/dsa/tag_brcm.c.

2020-09-23net: stmmac: removed enabling eee in EEE set callbackVoon Weifeng
EEE should be only be enabled during stmmac_mac_link_up() when the link are up and being set up properly. set_eee should only do settings configuration and disabling the eee. Without this fix, turning on EEE using ethtool will return "Operation not supported". This is due to the driver is in a dead loop waiting for eee to be advertised in the for eee to be activated but the driver will only configure the EEE advertisement after the eee is activated. Ethtool should only return "Operation not supported" if there is no EEE capbility in the MAC controller.

While the switch driver is written such that port 5 or 8 could be CPU ports, the use case on Broadcom STB chips is to use port 8 exclusively. The platform firmware does make port 5 comply to a proper DSA CPU port binding by specifiying an "ethernet" phandle. This is undesirable for now until we have an user-space configuration mechanism (such as devlink) which could support dynamically changing the port flavor at run time.
