2022-05-16spi: aspeed: Calibrate read timingsCédric Le Goater
To accommodate the different response time of SPI transfers on different boards and different SPI NOR devices, the Aspeed controllers provide a set of Read Timing Compensation registers to tune the timing delays depending on the frequency being used. The AST2600 SoC has one of these registers per device. On the AST2500 and AST2400 SoCs, the timing register is shared by all devices which is problematic to get good results other than for one device. The algorithm first reads a golden buffer at low speed and then performs reads with different clocks and delay cycle settings to find a breaking point. This selects a default good frequency for the CEx control register. The current settings are a bit optimistic as we pick the first delay giving good results. A safer approach would be to determine an interval and choose the middle value. Calibration is performed when the direct mapping for reads is created. Since the underlying spi-nor object needs to be initialized to create the spi_mem operation for direct mapping, we should be fine. Having a specific API would clarify the requirements though.

Things get more complex with multiple devices. The driver needs to also adjust the window of the next device to make sure that there is no overlap, even if there is no available device.

BMC firmware . New register set . 5 chip select pins (CE0 ∼ CE4) . supports NOR flash, NAND flash and SPI flash memory. . single, dual and quad mode. Each controller has a memory range on which flash devices contents are mapped. Each device is assigned a window that can be changed at bootime with the Segment Address Registers. Each SPI flash device can then be accessed in two modes: Command and User. When in User mode, SPI transfers are initiated with accesses to the memory segment of a device. When in Command mode, memory operations on the memory segment of a device generate SPI commands automatically using a Control Register for the settings. This initial patch adds support for User mode. Command mode needs a little more work to check that the memory window on the AHB bus fits the device size. It will come later when support for direct mapping is added. Single and dual mode RX transfers are supported. Other types than SPI are not supported.

2022-05-16dmaengine: tegra: Use platform_get_irq() to get IRQ resourceAkhil R
Use platform_irq_get() instead platform_get_resource() for IRQ resource to fix the probe failure. platform_get_resource() fails to fetch the IRQ resource as it might not be ready at that time. platform_irq_get() is also the recommended way to get interrupt as it directly gives the IRQ number and no conversion from resource is required.

2022-05-16net: fix dev_fill_forward_path with pppoe + bridgeFelix Fietkau
When calling dev_fill_forward_path on a pppoe device, the provided destination address is invalid. In order for the bridge fdb lookup to succeed, the pppoe code needs to update ctx->daddr to the correct value. Fix this by storing the address inside struct net_device_path_ctx Fixes: f6efc675c9dd ("net: ppp: resolve forwarding path for bridge pppoe devices") Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2022-05-16octeontx2-pf: Remove unnecessary synchronize_irq() before free_irq()Minghao Chi
Calling synchronize_irq() right before free_irq() is quite useless. On one hand the IRQ can easily fire again before free_irq() is entered, on the other hand free_irq() itself calls synchronize_irq() internally (in a race condition free way), before any state associated with the IRQ is freed.

2022-05-16mlx5: support BIG TCP packetsEric Dumazet
mlx5 supports LSOv2. IPv6 gro/tcp stacks insert a temporary Hop-by-Hop header with JUMBO TLV for big packets. We need to ignore/skip this HBH header when populating TX descriptor. Note that ipv6_has_hopopt_jumbo() only recognizes very specific packet layout, thus mlx5e_sq_xmit_wqe() is taking care of this layout only. v7: adopt unsafe_memcpy() and MLX5_UNSAFE_MEMCPY_DISCLAIMER v2: clear hopbyhop in mlx5e_tx_get_gso_ihs() v4: fix compile error for CONFIG_MLX5_CORE_IPOIB=y Signed-off-by: Coco Li <lixiaoyan@google.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Reviewed-by: Tariq Toukan <tariqt@nvidia.com> Cc: Saeed Mahameed <saeedm@nvidia.com> Cc: Leon Romanovsky <leon@kernel.org> Signed-off-by: David S.
