https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v6.1 This has been a very quiet release for the core but quite a busy one for drivers with a big crop of new drivers and lots of feature additions and fixes to existing ones: - A new string helper parse_int_array_user(). - Improvements to the SOF IPC4 code, especially around trace. - Support for AMD Rembrant DSPs, AMD Pink Sardine ACP 6.2, Apple Silcon systems, Everest ES8326, Intel Sky Lake and Kaby Lake, MediaTek MT8186 support, NXP i.MX8ULP DSPs, Qualcomm SC8280XP, SM8250 and SM8450 and Texas Instruments SRC4392 There is a conflict with the conversion of I2C remove functions to void in the cs42l42 driver which is fairly straightforward to resolve but should be highlighted to Linus.
2022-10-03net: wwan: iosm: Call mutex_init before locking itMaxim Mikityanskiy
wwan_register_ops calls wwan_create_default_link, which ends up in the ipc_wwan_newlink callback that locks ipc_wwan->if_mutex. However, this mutex is not yet initialized by that point. Fix it by moving mutex_init above the wwan_register_ops call. This also makes the order of operations in ipc_wwan_init symmetric to ipc_wwan_deinit.

2022-10-03octeontx2-pf: mcs: Introduce MACSEC hardware offloadingSubbaraya Sundeep
This patch introduces the macsec offload feature to cn10k PF netdev driver. The macsec offload ops like adding, deleting and updating SecYs, SCs, SAs and stats are supported. XPN support will be added in later patches. Some stats use same counter in hardware which means based on the SecY mode the same counter represents different stat. Hence when SecY mode/policy is changed then snapshot of current stats are captured. Also there is no provision to specify the unique flow-id/SCI per packet to hardware hence different mac address needs to be set for macsec interfaces.

2022-10-03octeontx2-af: cn10k: mcs: Handle MCS block interruptsGeetha sowjanya
Hardware triggers an interrupt for events like PN wrap to zero, PN crosses set threshold. This interrupt is received by the MCS_AF. MCS AF then finds the PF/VF to which SA is mapped and notifies them using mcs_intr_notify mbox message. PF/VF using mcs_intr_cfg mbox can configure the list of interrupts for which they want to receive the notification from AF.

2022-10-03octeontx2-af: cn10k: Introduce driver for macsec block.Geetha sowjanya
CN10K-B and CNF10K-B has macsec block(MCS) to encrypt and decrypt packets at MAC level. This block is a global resource with hardware resources like SecYs, SCs and SAs and is in between NIX block and RPM LMAC. CN10K-B silicon has only one MCS block which receives packets from all LMACS whereas CNF10K-B has seven MCS blocks for seven LMACs. Both MCS blocks are similar in operation except for few register offsets and some configurations require writing to different registers. Those differences between IPs are handled using separate ops. This patch adds basic driver and does the initial hardware calibration and parser configuration.

2022-10-03net: fec: using page pool to manage RX buffersShenwei Wang
This patch optimizes the RX buffer management by using the page pool. The purpose for this change is to prepare for the following XDP support. The current driver uses one frame per page for easy management. Added __maybe_unused attribute to the following functions to avoid the compiling warning. Those functions will be removed by a separate patch once this page pool solution is accepted. - fec_enet_new_rxbdp - fec_enet_copybreak The following are the comparing result between page pool implementation and the original implementation (non page pool). --- small packet (64 bytes) testing are almost the same --- no matter what the implementation is --- on both i.MX8 and i.MX6SX

2022-10-03bnx2x: fix potential memory leak in bnx2x_tpa_stop()Jianglei Nie
bnx2x_tpa_stop() allocates a memory chunk from new_data with bnx2x_frag_alloc(). The new_data should be freed when gets some error. But when "pad + len > fp->rx_buf_size" is true, bnx2x_tpa_stop() returns without releasing the new_data, which will lead to a memory leak. We should free the new_data with bnx2x_frag_free() when "pad + len > fp->rx_buf_size" is true.

2022-10-03net: sfp: add support for multigig RollBall transceiversMarek Behún
This adds support for multigig copper SFP modules from RollBall/Hilink. These modules have a specific way to access clause 45 registers of the internal PHY. We also need to wait at least 22 seconds after deasserting TX disable before accessing the PHY. The code waits for 25 seconds just to be sure.

2022-10-03net: phy: mdio-i2c: support I2C MDIO protocol for RollBall SFP modulesMarek Behún
Some multigig SFPs from RollBall and Hilink do not expose functional MDIO access to the internal PHY of the SFP via I2C address 0x56 (although there seems to be read-only clause 22 access on this address). Instead these SFPs PHY can be accessed via I2C via the SFP Enhanced Digital Diagnostic Interface - I2C address 0x51. The SFP_PAGE has to be selected to 3 and the password must be filled with 0xff bytes for this PHY communication to work. This extends the mdio-i2c driver to support this protocol by adding a special parameter to mdio_i2c_alloc function via which this RollBall protocol can be selected.

Instead of configuring the I2C mdiobus when SFP driver is probed, create/destroy the mdiobus before the PHY is probed for/after it is released. This way we can tell the mdio-i2c code which protocol to use for each SFP transceiver. Move the code that determines MDIO I2C protocol from sfp_sm_probe_for_phy() to sfp_sm_mod_probe(), where most of the SFP ID parsing is done. Don't allocate I2C bus if no PHY is expected.

2022-10-03net: phy: marvell10g: select host interface configurationRussell King
Select the host interface configuration according to the capabilities of the host if the host provided them. This is currently provided only when connecting PHY that is inside a SFP. The PHY supports several configurations of host communication: - always communicate with host in 10gbase-r, even if copper speed is lower (rate matching mode), - the same as above but use xaui/rxaui instead of 10gbase-r, - switch host SerDes mode between 10gbase-r, 5gbase-r, 2500base-x and sgmii according to copper speed, - the same as above but use xaui/rxaui instead of 10gbase-r. This mode of host communication, called MACTYPE, is by default selected by strapping pins, but it can be changed in software. This adds support for selecting this mode according to which modes are supported by the host. This allows the kernel to: - support SFP modules with 88X33X0 or 88E21X0 inside them Note: we use mv3310_select_mactype() for both 88X3310 and 88X3340, although 88X3340 does not support XAUI. This is not a problem because 88X3340 does not declare XAUI in it's supported_interfaces, and so this function will never choose that MACTYPE.

2022-10-03net: phylink: pass supported host PHY interface modes to phylib for SFP's PHYsMarek Behún
Pass the supported PHY interface types to phylib if the PHY we are connecting is inside a SFP, so that the PHY driver can select an appropriate host configuration mode for their interface according to the host capabilities. For example the Marvell 88X3310 PHY inside RollBall SFP modules defaults to 10gbase-r mode on host's side, and the marvell10g driver currently does not change this setting. But a host may not support 10gbase-r. For example Turris Omnia only supports sgmii, 1000base-x and 2500base-x modes. The PHY can be configured to use those modes, but in order for the PHY driver to do that, it needs to know which modes are supported.
