arm64: dts: ls1046ardb: set RGMII interfaces to RGMII_ID mode

2020-04-02T13:28:25+00:00

commit d79e9d7c1e4ba5f95f2ff3541880c40ea9722212 upstream. The correct setting for the RGMII ports on LS1046ARDB is to enable delay on both Rx and Tx so the interface mode used must be PHY_INTERFACE_MODE_RGMII_ID. Since commit 1b3047b5208a80 ("net: phy: realtek: add support for configuring the RX delay on RTL8211F") the Realtek 8211F PHY driver has control over the RGMII RX delay and it is disabling it for RGMII_TXID. The LS1046ARDB uses two such PHYs in RGMII_ID mode but in the device tree the mode was described as "rgmii". Changing the phy-connection-type to "rgmii-id" to address the issue.

arm64: dts: ls1043a-rdb: correct RGMII delay mode to rgmii-id

2020-04-02T13:28:24+00:00

commit 4022d808c45277693ea86478fab1f081ebf997e8 upstream. The correct setting for the RGMII ports on LS1043ARDB is to enable delay on both Rx and Tx so the interface mode used must be PHY_INTERFACE_MODE_RGMII_ID. Since commit 1b3047b5208a80 ("net: phy: realtek: add support for configuring the RX delay on RTL8211F") the Realtek 8211F PHY driver has control over the RGMII RX delay and it is disabling it for RGMII_TXID. The LS1043ARDB uses two such PHYs in RGMII_ID mode but in the device tree the mode was described as "rgmii_txid". This issue was not apparent at the time as the PHY driver took the same action for RGMII_TXID and RGMII_ID back then but it became visible (RX no longer working) after the above patch. Changing the phy-connection-type to "rgmii-id" to address the issue. Fixes: bf02f2ffe59c ("arm64: dts: add LS1043A DPAA FMan support") Signed-off-by: Madalin Bucur Signed-off-by: David S.

ARM: dts: N900: fix onenand timings

2020-04-02T13:28:24+00:00

commit 0c5220a3c1242c7a2451570ed5f5af69620aac75 upstream. Commit a758f50f10cf ("mtd: onenand: omap2: Configure driver from DT") started using DT specified timings for GPMC, and as a result the OneNAND stopped working on N900 as we had wrong values in the DT. Fix by updating the values to bootloader timings that have been tested to be working on Nokia N900 with OneNAND manufacturers: Samsung, Numonyx.

ARM: dts: imx6: phycore-som: fix arm and soc minimum voltage

commit 636b45b8efa91db05553840b6c0120d6fa6b94fa upstream. The current set minimum voltage of 730000µV seems to be wrong. I don't know the document which specifies that but the imx6qdl datasheets says that the minimum voltage should be 0.925V for VDD_ARM (LDO bypassed, lowest opp) and 1.15V for VDD_SOC (LDO bypassed, lowest opp).

perf map: Fix off by one in strncpy() size argument

2020-04-02T13:28:24+00:00

commit db2c549407d4a76563c579e4768f7d6d32afefba upstream. This patch fixes an off-by-one error in strncpy size argument in tools/perf/util/map.c. The issue is that in: strncmp(filename, "/system/lib/", 11) the passed string literal: "/system/lib/" has 12 bytes (without the NULL byte) and the passed size argument is 11. As a result, the logic won't match the ending "/" byte and will pass filepaths that are stored in other directories e.g. "/system/libmalicious/bin" or just "/system/libmalicious". This functionality seems to be present only on Android. I assume the /system/ directory is only writable by the root user, so I don't think this bug has much (or any) security impact.

net: ks8851-ml: Fix IO operations, again

2020-04-02T13:28:23+00:00

commit 8262e6f9b1034ede34548a04dec4c302d92c9497 upstream. This patch reverts 58292104832f ("net: ks8851-ml: Fix 16-bit IO operation") and edacb098ea9c ("net: ks8851-ml: Fix 16-bit data access"), because it turns out these were only necessary due to buggy hardware. This patch adds a check for such a buggy hardware to prevent any such mistakes again. While working further on the KS8851 driver, it came to light that the KS8851-16MLL is capable of switching bus endianness by a hardware strap, EESK pin. If this strap is incorrect, the IO accesses require such endian swapping as is being reverted by this patch. Such swapping also impacts the performance significantly. Hence, in addition to removing it, detect that the hardware is broken, report to user, and fail to bind with such hardware.
