      cpsw/netcp: refine cpts dependency · 504926df
      Arnd Bergmann authored
      Tony Lindgren reports a kernel oops that resulted from my compile-time
      fix on the default config. This shows two problems:
      a) configurations that did not already enable PTP_1588_CLOCK will
         now miss the cpts driver
      b) when cpts support is disabled, the driver crashes. This is a
         preexisting problem that we did not notice before my patch.
      While the second problem is still being investigated, this modifies
      the dependencies again, getting us back to the original state, with
      another 'select NET_PTP_CLASSIFY' added in to avoid the original
      link error we got, and the 'depends on POSIX_TIMERS' to hide
      the CPTS support when turning it on would be useless.

      cpsw/netcp: cpts depends on posix_timers · 07fef362
      Arnd Bergmann authored
      With posix timers having become optional, we get a build error with
      the cpts time sync option of the CPSW driver:
      drivers/net/ethernet/ti/cpts.c: In function 'cpts_find_ts':
      drivers/net/ethernet/ti/cpts.c:291:23: error: implicit declaration of function 'ptp_classify_raw';did you mean 'ptp_classifier_init'? [-Werror=implicit-function-declaration]
      This adds a hard dependency on PTP_CLOCK to avoid the problem, as
      building it without PTP support makes no sense anyway.

      cpsw/netcp: work around reverse cpts dependency · be9ca0d3
      Arnd Bergmann authored
      The dependency is reversed: cpsw and netcp call into cpts,
      but cpts depends on the other two in Kconfig. This can lead
      to cpts being a loadable module and its callers built-in:
      drivers/net/ethernet/ti/cpsw.o: In function `cpsw_remove':
      cpsw.c:(.text.cpsw_remove+0xd0): undefined reference to `cpts_release'
      drivers/net/ethernet/ti/cpsw.o: In function `cpsw_rx_handler':
      cpsw.c:(.text.cpsw_rx_handler+0x2dc): undefined reference to `cpts_rx_timestamp'
      drivers/net/ethernet/ti/cpsw.o: In function `cpsw_tx_handler':
      cpsw.c:(.text.cpsw_tx_handler+0x7c): undefined reference to `cpts_tx_timestamp'
      drivers/net/ethernet/ti/cpsw.o: In function `cpsw_ndo_stop':
      As a workaround, I'm introducing another Kconfig symbol to
      control the compilation of cpts, while making the actual
      module controlled by a silent symbol that is =y when necessary.

      drivers/net: remove all references to obsolete Ethernet-HOWTO · 138b15ed
      Paul Gortmaker authored
      This howto made sense in the 1990s when users had to manually configure
      ISA cards with jumpers or vendor utilities, but with the implementation
      of PCI it became increasingly less and less relevant, to the point where
      it has been well over a decade since I last updated it.  And there is
      no value in anyone else taking over updating it either.
      However the references to it continue to spread as boiler plate text
      from one Kconfig file into the next.  We are not doing end users any
      favours by pointing them at this old document, so lets kill it with
      fire, once and for all, to hopefully stop any further spread.
      No code is changed in this commit, just Kconfig help text.

      net: netcp: Add Keystone NetCP core ethernet driver · 84640e27
      Karicheri, Muralidharan authored
      The network coprocessor (NetCP) is a hardware accelerator available in
      Keystone SoCs that processes Ethernet packets. NetCP consists of following
      hardware components
       1 Gigabit Ethernet (GbE) subsystem with a Ethernet switch sub-module to
         send and receive packets.
       2 Packet Accelerator (PA) module to perform packet classification
         operations such as header matching, and packet modification operations
         such as checksum generation.
       3 Security Accelerator(SA) capable of performing IPSec operations on
         ingress/egress packets.
       4 An optional 10 Gigabit Ethernet Subsystem (XGbE) which includes a
         3-port Ethernet switch sub-module capable of 10Gb/s and 1Gb/s rates
         per Ethernet port.
       5 Packet DMA and Queue Management Subsystem (QMSS) to enqueue and dequeue
         packets and DMA the packets between memory and NetCP hardware components
         described above.
      NetCP core driver make use of the Keystone Navigator driver API to allocate
      DMA channel for the Ethenet device and to handle packet queue/de-queue,
      Please refer API's in include/linux/soc/ti/knav_dma.h and
      drivers/soc/ti/knav_qmss.h for details.
      NetCP driver consists of NetCP core driver and at a minimum Gigabit
      Ethernet (GBE) module (1) driver to implement the Network device function.
      Other modules (2,3) can be optionally added to achieve supported hardware
      acceleration function. The initial version of the driver include NetCP
      core driver and GBE driver modules.
      Please refer Documentation/devicetree/bindings/net/keystone-netcp.txt
      for design of the driver.

      drivers: net: cpsw-phy-sel: Add new driver for phy mode selection for cpsw · 5892cd13
      Mugunthan V N authored
      The cpsw currently lacks code to properly set up the hardware interface
      mode on AM33xx. Other platforms might be equally affected.
      Usually, the bootloader will configure the control module register, so
      probably that's why such support wasn't needed in the past. In suspend
      mode though, this register is modified, and so it needs reprogramming
      after resume.
      This patch adds a new driver in which hardware interface can configure
      correct register bits when the slave is opened.
      The AM33xx also has a bit for each slave to configure the RMII reference
      clock direction. Setting it is now supported by a per-slave DT property.
      This code path introducted by this patch is currently exclusive for
      am33xx and same can be extened to various platforms via the DT compatibility

      drivers/net/ethernet/*: Enabled vendor Kconfig options · 88f07484
      Jeff Kirsher authored
      Based on finds for Stephen Rothwell, where current defconfig's
      enable a ethernet driver and it is not compiled due to the newly
      added NET_VENDOR_* component of Kconfig.
      This patch enables all the "new" Kconfig options so that current
      defconfig's will continue to compile the expected drivers.  In
      addition, by enabling all the new Kconfig options does not add
      any un-expected options.
