Xen blkfront advertises its support of the persistent grants feature when it first setting up and when resuming in 'talk_to_blkback()'. Then, blkback reads the advertised value when it connects with blkfront and decides if it will use the persistent grants feature or not, and advertises its decision to blkfront. Blkfront reads the blkback's decision and it also makes the decision for the use of the feature. Commit 402c43ea ("xen-blkfront: Apply 'feature_persistent' parameter when connect"), however, made the blkfront's read of the parameter for disabling the advertisement, namely 'feature_persistent', to be done when it negotiate, not when advertise. Therefore blkfront advertises without reading the parameter. As the field for caching the parameter value is zero-initialized, it always advertises as the feature is disabled, so that the persistent grants feature becomes always disabled. This commit fixes the issue by making the blkfront does parmeter caching just before the advertisement.

The advertisement of the persistent grants feature (writing 'feature-persistent' to xenbus) should mean not the decision for using the feature but only the availability of the feature. However, commit 74a85247 ("xen-blkfront: add a parameter for disabling of persistent grants") made a field of blkfront, which was a place for saving only the negotiation result, to be used for yet another purpose: caching of the 'feature_persistent' parameter value. As a result, the advertisement, which should follow only the parameter value, becomes inconsistent. This commit fixes the misuse of the semantic by making blkfront saves the parameter value in a separate place and advertises the support based on only the saved value.

We have to copy only selected fields from the original resource. Because a PCI device will be removed immediately after getting its resources, we may not use any allocated data, hence we may not copy any pointers. Consider the following scenario: 1/ a caller of p2sb_bar() gets the resource; 2/ the resource has been copied by platform_device_add_data() in order to create a platform device; 3/ the platform device creation will call for the device driver's ->probe() as soon as a match found; 4/ the ->probe() takes given resources (see 2/) and tries to access one of its field, i.e. 'name', in the __devm_ioremap_resource() to create a pretty looking output; 5/ but the 'name' is a dangling pointer because p2sb_bar() removed a PCI device, which 'name' had been copied to the caller's memory. 6/ UAF (Use-After-Free) as a result.

Both __device_attach_driver() and __driver_attach() check the return code of the bus_type.match() function to see if the device needs to be added to the deferred probe list. After adding the device to the list, the logic attempts to bind the device to the driver anyway, as if the device had matched with the driver, which is not correct. If __device_attach_driver() detects that the device in question is not ready to match with a driver on the bus, then it doesn't make sense for the device to attempt to bind with the current driver or continue attempting to match with any of the other drivers on the bus. So, update the logic in __device_attach_driver() to reflect this. If __driver_attach() detects that a driver tried to match with a device that is not ready to match yet, then the driver should not attempt to bind with the device. However, the driver can still attempt to match and bind with other devices on the bus, as drivers can be bound to multiple devices. So, update the logic in __driver_attach() to reflect this.

Usually this is a duplicate input event with the "Video Bus" input device events. But on these devices the "Video Bus" does not send events for this key.

This patch adds logic to compute the MDIO period based on the i1clk, and thereafter write the MDIO period into the YU MDIO config register. The i1clk resource from the ACPI table is used to provide addressing to YU bootrecord PLL registers. The values in these registers are used to compute MDIO period. If the i1clk resource is not present in the ACPI table, then the current default hardcorded value of 430Mhz is used. The i1clk clock value of 430MHz is only accurate for boards with BF2 mid bin and main bin SoCs. The BF2 high bin SoCs have i1clk = 500MHz, but can support a slower MDIO period.

By using 16-bit I/O on the GPIO peripheral, which is apparently not safe on MIPS, the IMR can end up containing garbage. This then results in interrupt triggers for lines that don't have an interrupt handler associated. The irq_desc lookup fails, and the ISR will not be cleared, keeping the CPU busy until reboot, or until another IMR operation restores the correct value. This situation appears to happen very rarely, for < 0.5% of IMR writes. Instead of using 8-bit or 16-bit I/O operations on the 32-bit memory mapped peripheral registers, switch to using 32-bit I/O only, operating on the entire bank for all single bit line settings. For 2-bit line settings, with 16-bit port values, stick to manual (un)packing. This issue has been seen on RTL8382M (HPE 1920-16G), RTL8391M (Netgear GS728TP v2), and RTL8393M (D-Link DGS-1210-52 F3, Zyxel GS1900-48).

The same GPIO line can be shared by multiple phys for the coma mode pin. If that is the case then, all the other phys that share the same line will failed to be probed because the access to the gpio line is not non-exclusive. Fix this by making access to the gpio line to be nonexclusive using flag GPIOD_FLAGS_BIT_NONEXCLUSIVE. This allows all the other PHYs to be probed.
