| * | | | sh_eth: consolidate sh_eth_reset()Nobuhiro Iwamatsu2013-06-06

Consolidate every variation into a single function -- which allows us to get rid of some more #ifdef'fery.

| * | | | sh_eth: add IRQ flags to 'struct sh_eth_cpu_data'Nobuhiro Iwamatsu2013-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver supports some SH and SH-Mobile SOCs.

| * | | | net: mvneta: read MAC address from hardware when availableThomas Petazzoni2013-06-04

Until now, it was only looking at the Device Tree, and if no address was found, was falling back to generating a random MAC address. This patch adds the intermediate solution of reading the MAC address from the hardware registers, in case it has been set by the bootloader. So the order is now: 1) MAC address from the Device Tree 2) MAC address from the hardware registers 3) Random MAC address This requires moving the MAC address initialization a little bit later in the ->probe() code, because it now requires the hardware registers to be remapped.

FW_VERSION_T4 = 1.4.0.0 FW_VERSION_T5 = 0.0.0.0 At this point driver supports above and greater than above version of firmware. If it doesn't find the required firmware version than it forces the adapter to be reinitialized as shown below. 1) If FW_ON_ADAPTER < FW_VERSION and we're the MASTER_PF force uninitialized state and a FW upgrade if available. - If FW_ON_ADAPTER < /lib/firmware/cxgb4/t*fw.bin we will update the adapters FW. - If FW_ON_ADAPTER >= /lib/firmware/cxgb4/t*fw.bin don't upgrade FW. - If upgrade_fw() fails force reinitialization of the adapter anyways, it might still work. Either way forcing the uninitialized state allows cxgb4 reinitialize FW. 2) If FW_ON_ADAPTER >= FW_VERSION driver follows normal path.

The exact feature set of this controller is unknown, since there is no public documentation for this IP, and this driver is mostly the one published by Allwinner that has been heavily cleaned up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds device tree parsing support for the shared driver of mv643xx_eth. As the bindings are slightly different from current PPC bindings new binding documentation is also added. Following PPC-style device setup, the shared driver now also adds port platform_devices and sets up port platform_data.

This patch clears the CLK125_BYPASS_EN bit for DT enabled Kirkwood only by using of_device_is_compatible() instead of #ifdefs. Non-DT Kirkwood is not affected as it installs a clock gating workaround because of the MAC address issue above. Other Orion SoCs do not suffer from register reset, do not have the bit in question, or do not have the register at all. Moreover, system controllers on PPC using this driver should also be protected from clearing that bit. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Signed-off-by: David S.
