* net: stmmac: enable tx queue 0 for gmac4 IPs synthesized with multiple TX queuesNiklas Cassel2016-11-302-1/+14
| | | | | | | | | | | | | | The dwmac4 IP can synthesized with 1-8 number of tx queues. On an IP synthesized with DWC_EQOS_NUM_TXQ > 1, all txqueues are disabled by default. For these IPs, the bitfield TXQEN is R/W. Always enable tx queue 0. The write will have no effect on IPs synthesized with DWC_EQOS_NUM_TXQ == 1. The driver does still not utilize more than one tx queue in the IP. Signed-off-by: Niklas Cassel <niklas.cassel@axis.com> Signed-off-by: David S. Miller <davem@davemloft.net>

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All conflicts were simple overlapping changes except perhaps for the Thunder driver. That driver has a change_mtu method explicitly for sending a message to the hardware. If that fails it returns an error. Normally a driver doesn't need an ndo_change_mtu method becuase those are usually just range changes, which are now handled generically. But since this extra operation is needed in the Thunder driver, it has to stay. However, if the message send fails we have to restore the original MTU before the change because the entire call chain expects that if an error is thrown by ndo_change_mtu then the MTU did not change. Therefore code is added to nicvf_change_mtu to remember the original MTU, and to restore it upon nicvf_update_hw_max_frs() failue. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the ethtool stats for PTP frames; previous version does not take care about some message types: i.e. announce, management and signaling.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The stmmac driver use lots of pr_xxx functions to print information. This is bad since we cannot know which device logs the information. (moreover if two stmmac device are present) Furthermore, it seems that it assumes wrongly that all logs will always be subsequent by using a dev_xxx then some indented pr_xxx like this: kernel: sun7i-dwmac 1c50000.ethernet: no reset control found kernel: Ring mode enabled kernel: No HW DMA feature register supported kernel: Normal descriptors kernel: TX Checksum insertion supported So this patch replace all pr_xxx by their netdev_xxx counterpart. Excepts for some printing where netdev "cause" unpretty output like: sun7i-dwmac 1c50000.ethernet (unnamed net_device) (uninitialized): no reset control found In those case, I keep dev_xxx. In the same time I remove some "stmmac:" print since this will be a duplicate with that dev_xxx displays.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 52f95bbfcf72 ("stmmac: fix adjust link call in case of a switch is attached") added some logic to avoid polling the fixed PHY and therefore invoking the adjust_link callback more than once, since this is a fixed PHY and link events won't be generated. This works fine the first time, because we start with phydev->irq = PHY_POLL, so we call adjust_link, then we set phydev->irq = PHY_IGNORE_INTERRUPT and we stop polling the PHY. Now, if we called ndo_close(), which calls both phy_stop() and does an explicit netif_carrier_off(), we end up with a link down. Upon calling ndo_open() again, despite starting the PHY state machine, we have PHY_IGNORE_INTERRUPT set, and we generate no link event at all, so the link is permanently down.

This includes the newly added Nextthing GR8 platform, which is derived from sun5i/A13. - Some integrator (arm32) changes rely on clk driver changes. - A single patch for lpc32xx has no such dependency but wasn't added until just before the merge window" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (99 commits) ARM: dts: lpc32xx: add device node for IRAM on-chip memory ARM: dts: sun8i: Add accelerometer to polaroid-mid2407pxe03 ARM: dts: sun8i: enable UART1 for iNet D978 Rev2 board ARM: dts: sun8i: add pinmux for UART1 at PG dts: sun8i-h3: add I2C0-2 peripherals to H3 SOC dts: sun8i-h3: add pinmux definitions for I2C0-2 dts: sun8i-h3: associate exposed UARTs on Orange Pi Boards dts: sun8i-h3: split off RTS/CTS for UART1 in seperate pinmux dts: sun8i-h3: add pinmux definitions for UART2-3 ARM: dts: sun9i: a80-optimus: Disable EHCI1 ARM: dts: sun9i: cubieboard4: Add AXP806 PMIC device node and regulators ARM: dts: sun9i: a80-optimus: Add AXP806 PMIC device node and regulators ARM: dts: sun9i: cubieboard4: Declare AXP809 SW regulator as unused ARM: dts: sun9i: a80-optimus: Declare AXP809 SW regulator as unused ARM: dts: sun8i: Add touchscreen node for sun8i-a33-ga10h ARM: dts: sun8i: Add touchscreen node for sun8i-a23-polaroid-mid2809pxe04 ARM: dts: sun8i: Add touchscreen node for sun8i-a23-polaroid-mid2407pxe03 ARM: dts: sun8i: Add touchscreen node for sun8i-a23-inet86dz ARM: dts: sun8i: Add touchscreen node for sun8i-a23-gt90h ARM64: dts: meson-gxbb-vega-s95: Enable USB Nodes ...

| * net: stmmac: add a glue driver for the Amlogic Meson 8b / GXBB DWMACMartin Blumenstingl2016-09-073-4/+328
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Ethernet controller available in Meson8b and GXBB SoCs is a Synopsys DesignWare MAC IP core which is already supported by the stmmac driver. In addition to the standard stmmac driver some Meson8b / GXBB specific registers have to be configured for the PHY clocks. These SoC specific registers are called PRG_ETHERNET_ADDR0 and PRG_ETHERNET_ADDR1 in the datasheet. These registers are not backwards compatible with those on Meson 6b, which is why a new glue driver is introduced. This worked for many boards because the bootloader programs the PRG_ETHERNET registers correctly. Additionally the meson6-dwmac driver only sets bit 1 of PRG_ETHERNET_ADDR0 which (according to the datasheet) is only used during reset. Currently all configuration values can be determined automatically, based on the configured phy-mode (which is mandatory for the stmmac driver). If required the tx-delay and the mux clock (so it supports the MPLL2 clock as well) can be made configurable in the future.

| |/ | | | | | | | | | | | | | | | | | | | | | | MAC devices use the RWKPKTEN and MGKPKTEN bits of the PMT Control/Status register to generate power management events. So this patch is to properly set the RWKPKTEN [BIT(2)] inside the PMT register (needed in case of global unicast).

| | | | | | | | | | | | | | | | | | | | | | | | The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either built-in or as a module, use that macro instead of open coding the same. Using the macro makes the code more readable by helping abstract away some of the Kconfig built-in and module enable details.
