2021-02-15gpio: mvebu: don't limit pwm period/duty_cycle to UINT_MAXBaruch Siach
PWM on/off registers are limited to UINT_MAX. However the state period and duty_cycle fields are ns values of type u64. There is no reason to limit them to UINT_MAX.

Add support for the GPIO controller block in the R-Car V3U (R8A779A0) SoC, which is very similar to the block found on other R-Car Gen3 SoCs. However, this block has a new General Input Enable Register (INEN), whose reset state is to have all inputs disabled. Enable input for all available pins in probe and resume, to support the use of the General Input Register (INDT) for reading pin state at all times. This preserves backwards compatibility with other R-Car Gen3 SoCs, as recommended by the Hardware Manual.

2021-02-15gpio: rcar: Optimize GPIO pin state read on R-Car Gen3Geert Uytterhoeven
Currently, the R-Car GPIO driver treats R-Car Gen2 and R-Car Gen3 GPIO controllers the same. However, there exist small differences, like the behavior of the General Input Register (INDT): - On R-Car Gen1, R-Car Gen2, and RZ/G1, INDT only reflects the state of an input pin if the GPIO is configured for input, - On R-Car Gen3 and RZ/G2, INDT always reflects the state of the input pins. Hence to accommodate all variants, the driver does not use the INDT register to read the status of a GPIO line when configured for output, at the expense of doing 2 or 3 register reads instead of 1. Given register accesses are slow, change the .get() and .get_multiple() callbacks to always use INDT to read pin state on SoCs where this is supported.

2021-02-15xen-blkback: fix error handling in xen_blkbk_map()Jan Beulich
The function uses a goto-based loop, which may lead to an earlier error getting discarded by a later iteration. Exit this ad-hoc loop when an error was encountered. The out-of-memory error path additionally fails to fill a structure field looked at by xen_blkbk_unmap_prepare() before inspecting the handle which does get properly set (to BLKBACK_INVALID_HANDLE). Since the earlier exiting from the ad-hoc loop requires the same field filling (invalidation) as that on the out-of-memory path, fold both paths. While doing so, drop the pr_alert(), as extra log messages aren't going to help the situation (the kernel will log oom conditions already anyway). This is XSA-365.

Failure of the kernel part of the mapping operation should also be indicated as an error to the caller, or else it may assume the respective kernel VA is okay to access. Furthermore gnttab_map_refs() failing still requires recording successfully mapped handles, so they can be unmapped subsequently. This in turn requires there to be a way to tell full hypercall failure from partial success - preset map_op status fields such that they won't "happen" to look as if the operation succeeded. Also again use GNTST_okay instead of implying its value (zero). This is part of XSA-361.

To record the value for unmapping, we also better don't use our local p2m: In particular after a subsequent change it may not have got updated for all the batch elements.

The AM64x SoC contains a Mailbox IP instance with multiple clusters in the MAIN domain, and is a variant of the IP on current AM65x and J721E SoCs. The AM64x SoC has only 8 clusters with no interrupts routed to the A53 core on the first 2 clusters. The interrupt outputs from the IP do not go through any Interrupt Routers and are hard-wired to each processor, with only couple of interrupts from each cluster reaching the A53 core. The IP is also not built with the K3 safety feature in hardware. Add the support for this IP through a new compatible.

2021-02-15pinctrl: mediatek: Fix trigger type setting follow for unexpected interruptHailong Fan
When flipping the polarity will be generated interrupt under certain circumstances, but GPIO external signal has not changed. Then, mask the interrupt before polarity setting, and clear the unexpected interrupt after trigger type setting completed. Remove mtk_eint_flip_edge: because mtk_eint_unmask already calls it.

2021-02-15soc: ti: omap-prm: Fix reboot issue with invalid pcie reset map for dra7Tony Lindgren
Yongqin Liu <yongqin.liu@linaro.org> reported an issue where reboot hangs on beagleboard-x15. This started happening after commit 7078a5ba7a58 ("soc: ti: omap-prm: Fix boot time errors for rst_map_012 bits 0 and 1"). We now assert any 012 type resets on init to prevent unconfigured accelerator MMUs getting enabled on init depending on the bootloader or kexec configured state. Turns out that we now also wrongly assert dra7 l3init domain PCIe reset bits causing a hang during reboot. Let's fix the l3init reset bits to use a 01 map instead of 012 map. There are only two rstctrl bits and not three. This is documented in TRM "Table 3-1647. RM_PCIESS_RSTCTRL".

2021-02-14net: dsa: propagate extack to .port_vlan_filteringVladimir Oltean
Some drivers can't dynamically change the VLAN filtering option, or impose some restrictions, it would be nice to propagate this info through netlink instead of printing it to a kernel log that might never be read. Also netlink extack includes the module that emitted the message, which means that it's easier to figure out which ones are driver-generated errors as opposed to command misuse.

2021-02-14net: dsa: propagate extack to .port_vlan_addVladimir Oltean
Allow drivers to communicate their restrictions to user space directly, instead of printing to the kernel log. Where the conversion would have been lossy and things like VLAN ID could no longer be conveyed (due to the lack of support for printf format specifier in netlink extack), I chose to keep the messages in full form to the kernel log only, and leave it up to individual driver maintainers to move more messages to extack.
