2020-05-31mtd: rawnand: diskonchip: Fix the probe error pathMiquel Raynal
Not sure nand_cleanup() is the right function to call here but in any case it is not nand_release(). Indeed, even a comment says that calling nand_release() is a bit of a hack as there is no MTD device to unregister. So switch to nand_cleanup() for now and drop this comment. There is no Fixes tag applying here as the use of nand_release() in this driver predates by far the introduction of nand_cleanup() in commit d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources") which makes this change possible. However, pointing this commit as the culprit for backporting purposes makes sense even if it did not intruce any bug.

2020-05-30ravb: Mask PHY mode to avoid inserting delays twiceGeert Uytterhoeven
Until recently, the Micrel KSZ9031 PHY driver ignored any PHY mode ("RGMII-*ID") settings, but used the hardware defaults, augmented by explicit configuration of individual skew values using the "*-skew-ps" DT properties. The lack of PHY mode support was compensated by the EtherAVB MAC driver, which configures TX and/or RX internal delay itself, based on the PHY mode. However, now the KSZ9031 driver has gained PHY mode support, delays may be configured twice, causing regressions. E.g. on the Renesas Salvator-X board with R-Car M3-W ES1.0, TX performance dropped from ca. 400 Mbps to 0.1-0.3 Mbps, as measured by nuttcp. As internal delay configuration supported by the KSZ9031 PHY is too limited for some use cases, the ability to configure MAC internal delay is deemed useful and necessary. Hence a proper fix would involve splitting internal delay configuration in two parts, one for the PHY, and one for the MAC. However, this would require adding new DT properties, thus breaking DTB backwards-compatibility. Hence fix the regression in a backwards-compatibility way, by letting the EtherAVB driver mask the PHY mode when it has inserted a delay, to avoid the PHY driver adding a second delay. This also fixes messages like: Micrel KSZ9031 Gigabit PHY e6800000.ethernet-ffffffff:00: *-skew-ps values should be used only with phy-mode = "rgmii" as the PHY no longer sees the original RGMII-*ID mode. Solving the issue by splitting configuration in two parts can be handled in future patches, and would require retaining a backwards-compatibility mode anyway.

Anirudh (Ani) adds a poll for reset completion before proceeding with driver initialization when the DDP package fails to load and the firmware issues a core reset. Jake cleans up unnecessary code, since ice_set_dflt_vsi_ctx() performs a memset to clear the info from the context structures. Fixed a potential double free during probe unrolling after a failure. Also fixed a potential NULL pointer dereference upon register_netdev() failure. Tony makes two functions static which are not called outside of their file. Brett refactors the ice_ena_vf_mappings(), which was doing the VF's MSIx and queue mapping in one function which was hard to digest. So create a new function to handle the enabling MSIx mappings and another function to handle the enabling of queue mappings. Simplify the code flow in ice_sriov_configure(). Created a helper function for clearing VPGEN_VFRTRIG register, as this needs to be done on reset to notify the VF that we are done resetting it. Fixed the initialization/creation and reset flows, which was unnecessarily complicated, so separate the two flows into their own functions. Renamed VF initialization functions to make it more clear what they do and why. Added functionality to set the VF trust mode bit on reset. Added helper functions to rebuild the VLAN and MAC configurations when resetting a VF. Refactored how the VF reset is handled to prevent VF reset timeouts. Paul cleaned up code not needed during a CORER/GLOBR reset. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

The dynamic configuration interface for the General Params and the L2 Lookup Params tables was copy-pasted between E/T devices and P/Q/R/S devices. Nonetheless, these interfaces are bitwise different. The driver is using dynamic reconfiguration of the General Parameters table for the port mirroring feature, which was therefore broken on P/Q/R/S. Note that this patch can't be backported easily very far to stable trees (since it conflicts with some other development done since the introduction of the driver).

To save power in kernel idle, mailbox driver needs to support runtime PM in order to power off MU when it is unused. However, the runtime suspend/resume can ONLY be implemented in mailbox's .shutdown/.startup callback, so its consumer needs to call mbox_request_channel()/mbox_free_channel() in consumer driver's runtime PM callback, then the MU's power will be ON/OFF along with consumer's runtime PM status.

2020-05-30i2c: designware: Retrieve quirk flags as early as possibleSerge Semin
Some platforms might need to activate the driver quirks at a very early probe stage. For instance, Baikal-T1 System I2C doesn't need to map the registers space as ones belong to the system controller. Instead it will request the syscon regmap from the parental DT node. In order to be able to do so let's retrieve the model flags right after the DW I2C private data is created. While at it replace the or-assignment with just assignment operator since or-ing is redundant at this stage.

2020-05-30i2c: designware: Convert driver to using regmap APISerge Semin
Seeing the DW I2C driver is using flags-based accessors with two conditional clauses it would be better to replace them with the regmap API IO methods and to initialize the regmap object with read/write callbacks specific to the controller registers map implementation. This will be also handy for the drivers with non-standard registers mapping (like an embedded into the Baikal-T1 System Controller DW I2C block, which glue-driver is a part of this series). As before the driver tries to detect the mapping setup at probe stage and creates a regmap object accordingly, which will be used by the rest of the code to correctly access the controller registers. In two places it was appropriate to convert the hand-written read-modify-write and read-poll-loop design patterns to the corresponding regmap API ready-to-use methods. Note the regmap IO methods return value is checked only at the probe stage. The rest of the code won't do this because basically we have MMIO-based regmap so non of the read/write methods can fail (this also won't be needed for the Baikal-T1-specific I2C controller).
