+ occasions
+
+Add a small helper skb_postpush_rcsum() and fix up redirect locations
+that need CHECKSUM_COMPLETE fixups on ingress. dev_forward_skb() expects
+a proper csum that covers also Ethernet header, f.e. since 2c26d34bbcc0
+("net/core: Handle csum for CHECKSUM_COMPLETE VXLAN forwarding"), we
+also do skb_postpull_rcsum() after pulling Ethernet header off via
+eth_type_trans().
+
+When using eBPF in a netns setup f.e. with vxlan in collect metadata mode,
+I can trigger the following csum issue with an IPv6 setup:
+
+ [ 505.144065] dummy1: hw csum failure

+ [ 505.144259] [<ffffffff8160c4a5>] net_rx_action+0x145/0x320
+ [...]
+
+What happens is that on ingress, we push Ethernet header back in, either
+from cls_bpf or right before skb_do_redirect(), but without updating csum.
+The "hw csum failure" can be fixed by using the new skb_postpush_rcsum()
+helper for the dev_forward_skb() case to correct the csum diff again.
+
+Thanks to Hannes Frederic Sowa for the csum_partial() idea!

+Subject: [PATCH 394/423] dmaengine: bcm2835: remove unnecessary masking of dma
+ channels
+
+The original patch contained 3 dma channels that were masked out.
+
+These - as far as research and discussions show - are a
+artefacts remaining from the downstream legacy dma-api.
+
+Right now down-stream still includes a legacy api used only
+in a single (downstream only) driver (bcm2708_fb) that requires
+2D DMA for speedup (DMA-channel 0).
+Formerly the sd-card support driver also was using this legacy
+api (DMA-channel 2), but since has been moved over to use
+dmaengine directly.
+
+The DMA-channel 3 is already masked out in the devicetree in
+the default property "brcm,dma-channel-mask = <0x7f35>;"
+
+So we can remove the whole masking of DMA channels.

+Subject: [PATCH 398/423] dmaengine: bcm2835: limit max length based on channel
+ type
+
+The bcm2835 dma system has 2 basic types of dma-channels:
+* "normal" channels
+* "light" channels
+
+Lite channels are limited in several aspects:
+* internal data-structure is 128 bit (not 256)
+* does not support BCM2835_DMA_TDMODE (2D)
+* DMA length register is limited to 16 bit.
+ so 0-65535 (not 0-65536 as mentioned in the official datasheet)
+* BCM2835_DMA_S/D_IGNORE are not supported
+
+The detection of the type of mode is implemented by looking at
+the LITE bit in the DEBUG register for each channel.
+This allows automatic detection.
+
+Based on this the maximum block size is set to (64K - 4) or to 1G
+and this limit is honored during generation of control block
+chains. The effect is that when a LITE channel is used more
+control blocks are used to do the same transfer (compared
+to a normal channel).
+
+As there are several sources/target DREQS that are 32 bit wide
+we need to have the transfer to be a multiple of 4 as this would
+break the transfer otherwise.
+
+This is why the limit of (64K - 4) was chosen over the
+alternative of (64K - 4K).

+Subject: [PATCH 399/423] dmaengine: bcm2835: add slave_sg support to
+ bcm2835-dma
+
+Add slave_sg support to bcm2835-dma using shared allocation
+code for bcm2835_desc and DMA-control blocks already used by
+dma_cyclic.
+
+Note that bcm2835_dma_callback had to get modified to support
+both modes of operation (cyclic and non-cyclic).
+
+Tested using:
+* Hifiberry I2S card (using cyclic DMA)
+* fb_st7735r SPI-framebuffer (using slave_sg DMA via spi-bcm2835)
+playing BigBuckBunny for audio and video.

+Subject: [PATCH 401/423] dmaengine: bcm2835: use platform_get_irq_byname
+
+Use platform_get_irq_byname to allow for correct mapping of
+interrupts to dma channels.
+
+The currently implemented device tree is unfortunately
+implemented with the wrong assumption, that each dma-channel
+has its own dma channel, but dma-irq 11 is handling
+dma-channel 11-14 and dma-irq 12 is actually a "catch all"
+interrupt.
+
+So here we use the byname variant and require that interrupts
+are explicitly named via the interrupts-name property in the
+device tree.
+
+The use of shared interrupts is also implemented.
+
+As a side-effect this means we can now use dma channels 12, 13 and 14
+in a correct manner - also testing shows that onl using
+channels 11 to 14 for spi and i2s works perfectly (when playing
+some video)

+Subject: [PATCH 406/423] dmaengine: bcm2835: Fix cyclic DMA period splitting
+
+The code responsible for splitting periods into chunks that
+can be handled by the DMA controller missed to update total_len,
+the number of bytes processed in the current period, when there
+are more chunks to follow.
+
+Therefore total_len was stuck at 0 and the code didn't work at all.
+This resulted in a wrong control block layout and audio issues because
+the cyclic DMA callback wasn't executing on period boundaries.
+
+Fix this by adding the missing total_len update.

+Subject: [PATCH 407/423] dmaengine: bcm2835: Avoid splitting periods into very
+ small chunks
+
+The current cyclic DMA period splitting implementation can generate
+very small chunks at the end of each period. For example a 65536 byte
+period will be split into a 65532 byte chunk and a 4 byte chunk on
+the "lite" DMA channels.
+
+This increases pressure on the RAM controller as the DMA controller
+needs to fetch two control blocks from RAM in quick succession and
+could potentially cause latency issues if the RAM is tied up by other
+devices.
+
+We can easily avoid these situations by distributing the remaining
+length evenly between the last-but-one and the last chunk, making
+sure that split chunks will be at least half the maximum length the
+DMA controller can handle.
+
+This patch checks if the last chunk would be less than half of
+the maximum DMA length and if yes distributes the max len+4...max_len*1.5
+bytes evenly between the last 2 chunks. This results in chunk sizes
+between max_len/2 and max_len*0.75 bytes.

+
+The tx_status hook is supposed to be safe to call from interrupt
+context, but it wouldn't ever return completion for the last transfer,
+meaning you couldn't poll for DMA completion with interrupts masked.
+
+This fixes IRQ handling for bcm2835's DSI1, which requires using the

+
+This patch adds headphone and microphone capability to the Audio Injector sound card. The patch also sets the bit clock ratio for use in the bcm2835-i2s driver. The bcm2835-i2s can't handle an 8 kHz sample rate when the bit clock is at 12 MHz because its register is only 10 bits wide which can't represent the ch2 offset of 1508. For that reason, the rate constraint is added.

+"By default DAPM waits 5 seconds (pmdown_time) before shutting down

+ Unmute amp when ALSA device opened by a client. Mute, with 5 second delay
+ when ALSA device closed. (Re-opening the device within the 5 second close

+
+Revision 4, using gpiod.
+
+Revision 5, clean-up formatting before adding mute code.
+ - Convert tab plus 4 space formatting to 2x tab

+
+1) Try to avoid reducing overclock when a card is removed.
+
+2) Reset overclock on card insertion.
+
+3) Reduce logging when errors occur, lowering the severity of
+ some messages and making others conditional on the debug
+ flag.
+
+4) Attempt to identify a disconnected SD bus earlier, treating a
+ zero returned OCR (voltage support) as an error condition.

+Select software CS in bcm2708_common.dtsi, and disable the automatic
+conversion in the driver to allow hardware CS to be re-enabled with an
+overlay.
