-Subject: [PATCH 19/21] wifi: rtw88: sdio: Honor the host max_req_size in the
- RX path
-
-Lukas reports skb_over_panic errors on his Banana Pi BPI-CM4 which comes
-with an Amlogic A311D (G12B) SoC and a RTL8822CS SDIO wifi/Bluetooth
-combo card. The error he observed is identical to what has been fixed
-in commit e967229ead0e ("wifi: rtw88: sdio: Check the HISR RX_REQUEST
-bit in rtw_sdio_rx_isr()") but that commit didn't fix Lukas' problem.
-
-Lukas found that disabling or limiting RX aggregation works around the
-problem for some time (but does not fully fix it). In the following
-discussion a few key topics have been discussed which have an impact on
-this problem:
-- The Amlogic A311D (G12B) SoC has a hardware bug in the SDIO controller
-  which prevents DMA transfers. Instead all transfers need to go through
-  the controller SRAM which limits transfers to 1536 bytes
-- rtw88 chips don't split incoming (RX) packets, so if a big packet is
-  received this is forwarded to the host in it's original form
-- rtw88 chips can do RX aggregation, meaning more multiple incoming
-  packets can be pulled by the host from the card with one MMC/SDIO
-  transfer. This Depends on settings in the REG_RXDMA_AGG_PG_TH
-  register (BIT_RXDMA_AGG_PG_TH limits the number of packets that will
-  be aggregated, BIT_DMA_AGG_TO_V1 configures a timeout for aggregation
-  and BIT_EN_PRE_CALC makes the chip honor the limits more effectively)
-
-Use multiple consecutive reads in rtw_sdio_read_port() and limit the
-number of bytes which are copied by the host from the card in one
-MMC/SDIO transfer. This allows receiving a buffer that's larger than
-the hosts max_req_size (number of bytes which can be transferred in
-one MMC/SDIO transfer). As a result of this the skb_over_panic error
-is gone as the rtw88 driver is now able to receive more than 1536 bytes
-from the card (either because the incoming packet is larger than that
-or because multiple packets have been aggregated).
-
-In case of an receive errors (-EILSEQ has been observed by Lukas) we
-need to drain the remaining data from the card's buffer, otherwise the
-card will return corrupt data for the next rtw_sdio_read_port() call.
-
-Fixes: 65371a3f14e7 ("wifi: rtw88: sdio: Add HCI implementation for SDIO based chipsets")

+Subject: [PATCH 05/11] drm/imx: add driver for HDMI TX Parallel Video
+ Interface
+
+This IP block is found in the HDMI subsystem of the i.MX8MP SoC. It has a
+full timing generator and can switch between different video sources. On
+the i.MX8MP however the only supported source is the LCDIF. The block
+just needs to be powered up and told about the polarity of the video
+sync signals to act in bypass mode.

+Add a simple wrapper driver for the DWC HDMI bridge driver that
+implements the few bits that are necessary to abstract the i.MX8MP
+SoC integration.
