2023-02-12i2c: i801: make FEATURE_BLOCK_PROC dependent on FEATURE_BLOCK_BUFFERHeiner Kallweit
According to the datasheet the block process call requires block buffer mode. The user may disable block buffer mode by module parameter disable_features, in such a case we have to clear FEATURE_BLOCK_PROC.

2023-02-12i2c: i801: make FEATURE_HOST_NOTIFY dependent on FEATURE_IRQHeiner Kallweit
Host notification uses an interrupt, therefore it makes sense only if interrupts are enabled. Make this dependency explicit by removing FEATURE_HOST_NOTIFY if FEATURE_IRQ isn't set.

2023-02-12i2c: i801: improve interrupt handlerHeiner Kallweit
Not sure if it can happen, but better play safe: If SMBHSTSTS_BYTE_DONE and an error flag is set, then don't trust the result and skip calling i801_isr_byte_done(). In addition clear status bit SMBHSTSTS_BYTE_DONE in the main interrupt handler, this allows to simplify the code a little.

In the future, a new queue handling for timestamp will be implemented and this gptp flag is confusable. So, remove the gptp flag.

2023-02-10net: ethernet: ti: am65-cpsw: Add RX DMA Channel Teardown QuirkSiddharth Vadapalli
In TI's AM62x/AM64x SoCs, successful teardown of RX DMA Channel raises an interrupt. The process of servicing this interrupt involves flushing all pending RX DMA descriptors and clearing the teardown completion marker (TDCM). The am65_cpsw_nuss_rx_packets() function invoked from the RX NAPI callback services the interrupt. Thus, it is necessary to wait for this handler to run, drain all packets and clear TDCM, before calling napi_disable() in am65_cpsw_nuss_common_stop() function post channel teardown. If napi_disable() executes before ensuring that TDCM is cleared, the TDCM remains set when the interfaces are down, resulting in an interrupt storm when the interfaces are brought up again. Since the interrupt raised to indicate the RX DMA Channel teardown is specific to the AM62x and AM64x SoCs, add a quirk for it.
