Add KSZ9893 switch support in KSZ9477 driver. This switch is similar to KSZ9477 except the ingress tail tag has 1 byte instead of 2 bytes, so KSZ9893 tagging will be used. The XMII register that governs how the host port communicates with the MAC also has different register definitions. Signed-off-by: Tristram Ha <Tristram.Ha@microchip.com> Signed-off-by: David S.

2019-03-02Bluetooth: mediatek: add support for MediaTek MT7663U and MT7668U UART devicesSean Wang1-10/+271
This adds the support of enabling MT7663U and MT7668U Bluetooth function running on the top of btmtkuart driver. There are a few differences between MT766[3,8]U and MT7622 where MT766[3,8]U are standalone devices based on UART transport while MT7622 bluetooth is a built-in device on MediaTek SoC communicating with the host through BTIF serial transport. Thus, extra setup sequence is necessary for these standalone devices such as remote regulator and reset control via GPIO, baud rate changing handshake between the host and device and so on.

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.

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: 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.
