| * net: dsa: mv88e6xxx: fix races between lock and irq freeingUwe Kleine-König2018-07-211-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | free_irq() waits until all handlers for this IRQ have completed. As the relevant handler (mv88e6xxx_g1_irq_thread_fn()) takes the chip's reg_lock it might never return if the thread calling free_irq() holds this lock. For the same reason kthread_cancel_delayed_work_sync() in the polling case must not hold this lock. Also first free the irq (or stop the worker respectively) such that mv88e6xxx_g1_irq_thread_work() isn't called any more before the irq mappings are dropped in mv88e6xxx_g1_irq_free_common() to prevent the worker thread to call handle_nested_irq(0) which results in a NULL-pointer exception.

* | net: dsa: realtek-smi: Add Realtek SMI driverLinus Walleij2018-07-186-0/+2584
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a driver core for the Realtek SMI chips and a subdriver for the RTL8366RB. I just added this chip simply because it is all I can test. The code is a massaged variant of the code that has been sitting out-of-tree in OpenWRT for years in the absence of a proper switch subsystem. This creates a DSA driver for it. I have tried to credit the original authors wherever possible. The main changes I've done from the OpenWRT code: - Added an IRQ chip inside the RTL8366RB switch to demux and handle the line state IRQs. - Distributed the phy handling out to the PHY driver. - Added some RTL8366RB code that was missing in the driver at the time, such as setting up "green ethernet" with a funny jam table and forcing MAC5 (the CPU port) into 1 GBit. - Select jam table and add the default jam table from the vendor driver, also for ASIC "version 0" if need be. - Do not store jam tables in the device tree, store them in the driver. - Pick in the "initvals" jam tables from OpenWRT's driver and make those get selected per compatible for the whole system. It's apparently about electrical settings for this system and whatnot, not really configuration from device tree. - Implemented LED control: beware of bugs because there are no LEDs on the device I am using! We do not implement custom DSA tags. This is explained in a comment in the driver as well: this "tagging protocol" is not simply a few extra bytes tagged on to the ethernet frame as DSA is used to. Instead, enabling the CPU tags will make the switch start talking Realtek RRCP internally. For example a simple ping will make this kind of packets appear inside the switch: 0000 ff ff ff ff ff ff bc ae c5 6b a8 3d 88 99 a2 00 0010 08 06 00 01 08 00 06 04 00 01 bc ae c5 6b a8 3d 0020 a9 fe 01 01 00 00 00 00 00 00 a9 fe 01 02 00 00 0030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 As you can see a custom "8899" tagged packet using the protocol 0xa2. Norm RRCP appears to always have this protocol set to 0x01 according to OpenRRCP. You can also see that this is not a ping packet at all, instead the switch is starting to talk network management issues with the CPU port. So for now custom "tagging" is disabled. This was tested on the D-Link DIR-685 with initramfs and OpenWRT userspaces and works fine on all the LAN ports (lan0 .. lan3). The WAN port is yet not working.

They can also be configured to use an external CPU handling the switch in a memory-mapped manner by connecting to that external CPU's memory bus. This driver (currently) only takes control of the switch chip over SPI and configures it to route packages around when connected to a CPU port. The chip has embedded PHYs and VLAN support so we model it using DSA as a best fit so we can easily add VLAN support and maybe later also exploit the internal frame header to get more direct control over the switch. The four built-in GPIO lines are exposed using a standard GPIO chip. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>

This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

* net: dsa: b53: Fix for brcm tag issue in Cygnus SoCArun Parameswaran2018-06-063-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | In the Broadcom Cygnus SoC, the brcm tag needs to be inserted in between the mac address and the ether type (should use 'DSA_PROTO_TAG_BRCM') for the packets sent to the internal b53 switch. Since the Cygnus was added with the BCM58XX device id and the BCM58XX uses 'DSA_PROTO_TAG_BRCM_PREPEND', the data path is broken, due to the incorrect brcm tag location. Add a new b53 device id (BCM583XX) for Cygnus family to fix the issue. Add the new device id to the BCM58XX family as Cygnus is similar to the BCM58XX in most other functionalities.

A large amount of what needs to be done already exists under bcm_sf2_sw_adjust_link() so we are essentially breaking this down into the necessary operation for PHYLINK to work: mac_config, mac_link_up, mac_link_down and validate. We can now entirely get rid of most of what fixed_link_update() provided because only the link information is actually necessary.
