2019-03-01net: mvpp2: set the GMAC, XLG MAC, XPCS and MPCS in reset when a port is downAntoine Tenart1-0/+3
This patch adds calls in the stop() helper to ensure both MACs and both PCS blocks are set in reset when the user manually sets a port down. This is done so that we have the exact same block reset states at boot time and when a port is set down. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-03-01net: mvpp2: set the XPCS and MPCS in reset when not usedAntoine Tenart2-8/+59
This patch sets both the XPCS and MPCS blocks in reset when they aren't used. This is done both at boot time and when reconfiguring a port mode. The advantage now is that only the PCS used is set out of reset when the port is configured (10GKR uses the MCPS while RXAUI uses the XPCS).

2019-03-01net: mvpp2: reset the MACs when reconfiguring a portAntoine Tenart1-0/+3
This patch makes sure both PPv2 MACs (GMAC + XLG MAC) are set in reset while a port is reconfigured. This is done so that we make sure a MAC is in a reset state when not used, as only one of the two will be set out of reset after the port is configured properly.

2019-03-01net: mvpp2: rework the XLG MAC reset handlingAntoine Tenart1-9/+18
This patch reworks the way the XLG MAC is set in reset: the XLG MAC is set in reset at probe time and taken out of this state only when used. The idea is to move forward a situation where only the blocks used are taken out of reset. This also has the effect to handle the GMAC and the XLG MAC in a similar way (the GMAC already is set in reset at boot time).

2019-03-01net: mvpp2: force the XLG MAC link up or down when not using in-bandAntoine Tenart2-10/+27
This patch force the XLG MAC link state in the phylink link_up() and link_down() helpers when not using in-band auto-negotiation. This mimics what's already done for the GMAC and follows what's advised in the phylink documentation. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-03-01net: mvpp2: only update the XLG configuration when neededAntoine Tenart1-5/+8
This patch improves the XLG configuration function, to only update the XLG configuration register when a change is needed. This helps not writing over and over the same XLG configuration each time phylink request the MAC to be configured. This mimics the GMAC configuration function.

2019-03-01net: mvpp2: always disable both MACs when disabling a portAntoine Tenart1-4/+4
This patch modifies the port_disable() helper to always disable both the GMAC and the XLG MAC when called. At boot time we do not know of a port was enabled in the firmware/bootloader, and if so what mode was used (hence which of the two MACs was used). This also help in implementing a logic where all blocks are disabled when not used, and only enabled regarding the current mode used on a given port.

2019-03-01net: mvpp2: some AN fields require the link to be down when updatedAntoine Tenart1-1/+11
The GMAC configuration helper modifies values in the auto-negotiation register. Some of its values require the port to be forced down when modifying their values. This patches fixes the check made on the bit to be updated in this register, so that the port is forced down when needed. This fix cases where some of those parameters were updated, but not taken into account, such as when using RGMII interfaces.

2019-03-01net: mvpp2: fix the computation of the RXQsAntoine Tenart2-10/+17
The patch fixes the computation of RXQs being used by the PPv2 driver, which is set depending on the PPv2 engine version and the queue mode used. There are three cases: - PPv2.1: 1 RXQ per CPU. - PPV2.2 with MVPP2_QDIST_MULTI_MODE: 1 RXQ per CPU. - PPv2.2 with MVPP2_QDIST_SINGLE_MODE: 1 RXQ is shared between the CPUs. The PPv2 engine supports a maximum of 32 queues per port. This patch adds a check so that we do not overstep this maximum. It appeared the calculation was broken for PPv2.1 engines since f8c6ba8424b0, as PPv2.1 ports ended up with a single RXQ while they needed 4. This patch fixes it.

The Phylink validate function is the Marvell PPv2 driver makes a check on the GoP id. This is valid an has to be done when using PPv2.2 engines but makes no sense when using PPv2.1. The check done when using an RGMII interface makes sure the GoP id is not 0, but this breaks PPv2.1. Fixes it.

It turned out the interrupt can still be used with the port disabled. We can thus remove this check. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S.

By adding a check for an optional key/value pair to the test case data, individual test cases may be skipped to prevent tdc from aborting a test run due to setup or teardown failure. If a test case is skipped, it will still appear in the results output to allow for a consistent number of executed tests in each run. However, the test will be marked as skipped.

2019-03-01nfp: nsp: set higher timeout for flash bundleDirk van der Merwe1-4/+1
The management firmware now supports being passed a bundle with multiple components to be stored in flash at once. This makes it easier to update all components to a known state with a single user command, however, this also has the potential to increase the time required to perform the update significantly. The management firmware only updates the components out of a bundle which are outdated, however, we need to make sure we can handle the absolute worst case where a CPLD update can take a long time to perform. We set a very conservative total timeout of 900s which already adds a contingency.
