After magic pattern comming during system suspend status, system will be waked up, and irq handler will be running, there have enet register access. Since all clocks are disabled in suspend, and clocks are enabled after resume function. But irq handler run before resume function.

Execution 'ethtool -S' on fec device that is down causes OOPS on Vybrid board: Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0898200 pgd = ddecc000 [e0898200] *pgd=9e406811, *pte=400d1653, *ppte=400d1453 Internal error: : 1008 [#1] SMP ARM ... Reason of OOPS is that fec_enet_get_ethtool_stats() accesses fec registers while IPG clock is stopped by PM. Fix that by caching statistics in fec_enet_private. Cache is initialized at device probe time, and updated at statistics request time if device is up, and also just before turning device off on down path. Additional locking is not needed, since cached statistics is accessed either before device is registered, or under rtnl_lock().

2016-01-25net: fec: use CONFIG_ARM instead of CONFIG_ARCH_MXC/SOC_IMX28Johannes Berg
As Arnd Bergmann points out, using CONFIG_ARCH_MXC and/or SOC_IMX28 is wrong if some other ARM platform uses this device - the operation of the driver would depend on an unrelated ARM platform that might or might not be set for multi-platform kernels. Prior to my previous patch, any other platforms using it would have been broken already due to having the cbd_datlen/cbd_sc fields in the wrong order, but byte ordering correctly, so no such platforms can exist and work today. In any case, it seems likely that only Freescale SoCs use this part, and those are little-endian on ARM, so CONFIG_ARM is safe for them.

2016-01-25net: fec: make driver endian-safeJohannes Berg
The driver treats the device descriptors as CPU-endian, which appears to be correct with the default endianness on both ARM (typically LE) and PowerPC (typically BE) SoCs, indicating that the hardware block is generated differently. Add endianness annotations and byteswaps as necessary. It's not clear that the ifdef there really is correct and shouldn't just be #ifdef CONFIG_ARM, but I also can't test on anything but the i.MX6 HummingBoard where this gets it working with a BE kernel.

2015-06-28net: fec: don't access RACC register when not availableGreg Ungerer
Not all silicon implementations of the Freescale FEC hardware module have the RACC (Receive Accelerator Function) register, so we should not be trying to access it on those that don't. Currently none of the ColdFire based parts with a FEC have it. Support for RACC was introduced by commit 4c09eed9 ("net: fec: Enable imx6 enet checksum acceleration"). A fix was introduced in commit d1391930 ("net: fec: Fix build for MCF5272") that disables its use on the ColdFire M5272 part, but it doesn't fix the general case of other ColdFire parts. To fix we create a quirk flag, FEC_QUIRK_HAS_RACC, and check it before working with the RACC register. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: David S.

2015-01-14net: fec: fix MDIO bus assignement for dual fec SoC'sStefan Agner
On i.MX28, the MDIO bus is shared between the two FEC instances. The driver makes sure that the second FEC uses the MDIO bus of the first FEC. This is done conditionally if FEC_QUIRK_ENET_MAC is set. However, in newer designs, such as Vybrid or i.MX6SX, each FEC MAC has its own MDIO bus. Simply removing the quirk FEC_QUIRK_ENET_MAC is not an option since other logic, triggered by this quirk, is still needed. Furthermore, there are board designs which use the same MDIO bus for both PHY's even though the second bus would be available on the SoC side. Such layout are popular since it saves pins on SoC side. Due to the above quirk, those boards currently do work fine. The boards in the mainline tree with such a layout are: - Freescale Vybrid Tower with TWR-SER2 (vf610-twr.dts) - Freescale i.MX6 SoloX SDB Board (imx6sx-sdb.dts) This patch adds a new quirk FEC_QUIRK_SINGLE_MDIO for i.MX28, which makes sure that the MDIO bus of the first FEC is used in any case. However, the boards above do have a SoC with a MDIO bus for each FEC instance. But the PHY's are not connected in a 1:1 configuration. A proper device tree description is needed to allow the driver to figure out where to find its PHY. This patch fixes that shortcoming by adding a MDIO bus child node to the first FEC instance, along with the two PHY's on that bus, and making use of the phy-handle property to add a reference to the PHY's.

iMX6SX IEEE 1588 module has one hw issue in capturing the ATVR register. The current SW flow is: ENET0->ATCR |= ENET_ATCR_CAPTURE_MASK; ts_counter_ns = ENET0->ATVR; The ATVR value is not expected value that cause LinuxPTP stack cannot be convergent. ENET Block Guide/ Chapter for the iMX6SX (PELE) address the issue: After set ENET_ATCR[Capture], there need some time cycles before the counter value is capture in the register clock domain. The wait-time-cycles is at least 6 clock cycles of the slower clock between the register clock and the 1588 clock. So need something like: ENET0->ATCR |= ENET_ATCR_CAPTURE_MASK; wait(); ts_counter_ns = ENET0->ATVR; For iMX6SX, the 1588 ts_clk is fixed to 25Mhz, register clock is 66Mhz, so the wait-time-cycles must be greater than 240ns (40ns * 6).
