2022-08-17hantro: Remove incorrect HEVC SPS validationEzequiel Garcia3-15/+7
[ Upstream commit df9ec2fc8e70e01532fd9161cd98711969561ff6 ] Currently, the driver tries to validat the HEVC SPS against the CAPTURE queue format (i.e. the decoded format). This is not correct, because typically the SPS control is set before the CAPTURE queue is negotiated.

[ Upstream commit 143201a6435bf65f0115435e9dc6d95c66b908e9 ] Not all DPB entries will be used most of the time. Unused entries will thus have invalid timestamps. They will produce negative buffer index which is not specifically handled. This works just by chance in current code. It will even produce bogus pointer, but since it's not used, it won't do any harm. Let's fix that brittle design by skipping writing DPB entry altogether if timestamp is invalid.

2022-08-17wifi: ath11k: Fix register write failure on QCN9074Manikanta Pubbisetty6-69/+128
[ Upstream commit 867f4eeee862d6568a0f142d6a38f8bb724ff80e ] Commit 56c8ccf331bd ("ath11k: Add register access logic for WCN6750") regressed QCN9074. With the above mentioned commit, writes are failing for some registers on QCN9074 although the device seems to work normally. ath11k_pci 0000:03:00.0: failed to set pcie link register0x01e0e0a8: 0xffffffff != 0x00000010 ath11k_pci 0000:03:00.0: failed to set sysclk: -110 PCIe devices in ath11k (QCA6390, WCN6855, QCN9074, WCN6750) use window concept for register accesses. There are two schemes, dynamic & static window. In dynamic window scheme, a single window(region in the BAR) is mapped either to CE or DP register windows at any give time. QCA6390 & WCN6855 follow this scheme for register accesses. In static window scheme, CE & DP register windows are statically mapped to separate regions with in the BAR so that there is no switching of register windows between CE & DP register accesses. QCN9074 & WCN6750 follow this scheme although the window start offsets are different for QCN9074 & WCN6750. QCN9074 uses 3rd & 2nd window for DP & CE register accesses respectively whereas WCN6750 uses 1st & 2nd window for DP & CE. In QCN9074, along with 2nd & 3rd windows, 1st window is also used for certain configurations which commit 56c8ccf331bd ("ath11k: Add register access logic for WCN6750") did not account for and hence the regression. Fix this by going back to the original way of accessing the registers on QCN9074. Since this diverges from WCN6750 way of accessing registers, it is required to register window_read32/window_write32() pci_ops for WCN6750. We can also get rid of dp_window_idx & ce_window_idx members in hw_params, so remove them. Also add a new API ath11k_pcic_register_pci_ops() for registering pci_ops to the ath11k core. This API checks for mandatory pci_ops() and reports error if those are missing. Also initialize unused pci_ops to NULL.

2022-08-17i2c: cadence: Support PEC for SMBus block readLars-Peter Clausen1-1/+9
[ Upstream commit 9fdf6d97f03035ad5298e2d1635036c74c2090ed ] SMBus packet error checking (PEC) is implemented by appending one additional byte of checksum data at the end of the message. This provides additional protection and allows to detect data corruption on the I2C bus. SMBus block reads support variable length reads. The first byte in the read message is the number of available data bytes. The combination of PEC and block read is currently not supported by the Cadence I2C driver. * When PEC is enabled the maximum transfer length for block reads increases from 33 to 34 bytes. * The I2C core smbus emulation layer relies on the driver updating the `i2c_msg` `len` field with the number of received bytes. The updated length is used when checking the PEC. Add support to the Cadence I2C driver for handling SMBus block reads with PEC. To determine the maximum transfer length uses the initial `len` value of the `i2c_msg`. When PEC is enabled this will be 2, when it is disabled it will be 1. Once a read transfer is done also increment the `len` field by the amount of received data bytes. This change has been tested with a UCM90320 PMBus power monitor, which requires block reads to access certain data fields, but also has PEC enabled by default.

[ Upstream commit bee5395ced44c5a312348557eb2dfb0c2a7bfaa2 ] Bluetooth HCI devices indicate if they are able to wakeup in the wakeup callback since 'commit 4539ca67fe8e ("Bluetooth: Rename driver .prevent_wake to .wakeup")'.

[ Upstream commit 7b0a0e3c3a88260b6fcb017e49f198463aa62ed1 ] In order to support multi-link operation with multiple links, start adding some APIs. The notable addition here is to have the link ID in a new nl80211 attribute, that will be used to differentiate the links in many nl80211 operations. So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID attribute (as well as the NL80211_ATTR_MLO_LINKS attribute) and plugs it through the system in some places, checking the validity etc. along with other infrastructure needed for it. For now, I've decided to include only the over-the-air link ID in the API. I know we discussed that we eventually need to have to have other ways of identifying a link, but for local AP mode and auth/assoc commands as well as set_key etc. we'll use the OTA ID. Also included in this patch is some refactoring of the data structures in struct wireless_dev, splitting for the first time the data into type dependent pieces, to make reasoning about these things easier.
