2026-05-14rtc: ds1307: Handle oscillator stop flag set on ds1339 chipRonan Dalton
Currently the oscillator stop flag (OSF) bit is never checked or cleared on the DS1339 RTC chip. On getting the time from the RTC, check if the OSF bit is set, log a warning, and clear the flag. This matches the behavior of the DS1337 chip. Note that the `date` command always reads from the RTC even when setting or resetting the date, so the OSF flag is cleared in those cases as well.

2026-05-12Merge patch series "add memdup_nul(), use it and memdup() in a few places"Tom Rini
Rasmus Villemoes <[email protected]> says: There are quite a few places where we allocate X+1 bytes, initialize the first X bytes via memcpy() and then set the last byte to 0. The kernel has a helper for that, kmemdup_nul(). Introduce a similar one, and start making use of it in a few places. Also the existing memdup() helper can be put to more use. There are lots more places one could modify. But for code shared with host tools, one would need to do some refactoring, putting memdup() and memdup_nul() in their own str-util.c TU which could then also be included in the tools build.

2026-05-12mmc: sdhci-cadence: trigger tuning for SD HS mode on SD6HC (v6) PHYTze Yee Ng
The Cadence SD6HC (SDHCI spec v4.20+) controller uses a soft PHY whose DLL delay characteristics vary with PVT (Process, Voltage, Temperature) and board-level trace routing. A static delay value programmed via device tree for SD High Speed mode is insufficient because the optimal sampling point varies per board, SD card, and operating conditions. Runtime calibration is required. While the SD Physical Layer Specification does not mandate tuning for SD HS mode (only for UHS-I SDR50/SDR104), the Cadence SD6HC PHY requires runtime calibration of its receive data delay line to find a valid sampling window under constrained clock conditions. The tuning is triggered from the set_ios_post callback because at that moment hardware has committed the new bus width, clock frequency, and speed mode to the controller registers. This ensuring the tuning sequence runs at the correct SD HS operating conditions. The tuning is gated by a device tree property "cdns,sd-hs-tuning" so that only boards requiring runtime calibration opt in. When enabled, the driver performs a 40-tap DLL sweep using CMD19 to find the largest consecutive passing window, then programs the midpoint into PHY_DLL_SLAVE_CTRL_REG. To enable on a board, add to the MMC node in device tree: &mmc { cdns,sd-hs-tuning; }; Signed-off-by: Tze Yee Ng <[email protected]>

Cadence Ethernet MAC has a feature named user_io, which provides some input and some output signals for arbitrary purpose in the SoC. From the driver code, I understand that, on Atmel SoC, it is used to drive the PHY mode. At least on Cadence IP7014 r1p12, this feature is optional, and I am working on a SoC that does not instantiate it. The presence of this feature is advertised in DCFG1, this patch merely disables the access to the user_io register based on this information. I did not apply this change to the non-gigabit capable versions of the IP, as I do not have documentation for them, and a new non-gigabit instance is unlikely to appear. I prefer avoiding regressions on old systems. Signed-off-by: Christian DREHER <[email protected]>

2026-05-06net: phy: dp83867: default to 2ns delay if unspecified in device-treeSiddharth Vadapalli
Since Linux commit c360eb0c3ccb ("dt-bindings: net: ethernet-controller: Add informative text about RGMII delays"), the interpretation of RGMII delays has changed. Prior to the commit, the RGMII Variant among "rgmii", "rgmii-id", "rgmii-rxid" and "rgmii-txid" clearly specified whether it is the MAC or the PHY that "should" add the delay. However, post that commit, the RGMII Variant only specifies whether or not there is a delay on the PCB traces between the MAC and the PHY, leaving it open as to who adds the delay. Hence, instead of enforcing the existence of the device-tree properties "ti,rx-internal-delay" and "ti,tx-internal-delay", default to a delay of 2ns, while continuing to override this delay with the aforementioned properties, if they exist in the device-tree. This is in line with the Linux driver implementation updated by commit 6bf78849371d ("net: phy: dp83867: use 2ns delay if not specified in DTB").

So, the A10 OOB Layout is: [4Bytes USER_DATA_STEP0] [ECC_STEP0 bytes] [4bytes USER_DATA_STEP1] [ECC_STEP1 bytes] ... NB: the BBM is stored at the beginning of the USER_DATA_STEP0. Now, for H6/H616 NAND flash controller, this user data can have a different size for each step. So, we are maximizing the user data length to use as many OOB bytes as possible.
