The adis library only allows to define a `startup_delay` which for some devices is enough. However, other devices define different timeouts with significantly different timings which could lead to devices to not wait enough time or to wait a lot more than necessary (which is not efficient). This patch introduces a new timeout struct that must be passed into `adis_init()`. There are mainly, for now, three timeouts used. This is also an introductory patch with the goal of refactoring `adis_initial_startup()`. New driver's (eg: adis16480, adis16460) are replicating code for the device initial setup. With some changes (being this the first one) we can pass this to `adis_initial_startup()`. Signed-off-by:

dma_request_slave_channel() is a wrapper on top of dma_request_chan() eating up the error code. The dma_request_chan() is the standard API to request slave channel, clients should be moved away from the legacy API to allow us to retire them. Signed-off-by:

The driver reporting IEEE80211_TX_STAT_ACK is not being handled correctly. The driver should only report on TSR_TMO flag is not set indicating no transmission errors and when not IEEE80211_TX_CTL_NO_ACK is being requested. Cc: stable <stable@vger.kernel.org> Signed-off-by:

It appears that the drivers does not go into power save correctly the NULL data packets are not being transmitted because it not enabled in mac80211. The driver needs to capture ieee80211_is_nullfunc headers and copy the duration_id to it's own duration data header. Cc: stable <stable@vger.kernel.org> Signed-off-by:

It appears that the driver still transmits in CTS protect mode even though it is not enabled in mac80211. That is both packet types PK_TYPE_11GA and PK_TYPE_11GB both use CTS protect. The only difference between them GA does not use B rates. Find if only B rate in GB or GA in protect mode otherwise transmit packets as PK_TYPE_11A. Cc: stable <stable@vger.kernel.org> Signed-off-by:

Currently calls to wfx_alloc_hif are not checking for a null return when a memory allocation fails and this leads to null pointer dereferencing issues. Fix this by adding null pointer checks and returning passing down -ENOMEM errors where necessary. The error checking in the current driver is a bit sparse, so this may need some extra attention later if required. Fixes: f95a29d4 ("staging: wfx: add HIF commands helpers") Signed-off-by:

This adds support for the BMA254 variant of this accelerometer. The only difference for the simple IIO driver is that values are 12 bit and the temperature offset differs by 1 degree. Whilst wildcards in naming are normally frowned upon: The cases where I have labeled variables "25x" is where the models are identical, so as to make things easier for people that want to add support for BMA253 and BMA255.

There is no evidence of officially registered ACPI IDs for these devices. Thus, revert ACPI support from the driver. All authors of the respective changes are being informed here: d5c94568 ("iio: add bmp280 pressure and temperature driver") 6dba72ec ("iio: pressure: bmp280: add support for BMP180") 14beaa8f ("iio: pressure: bmp280: add humidity support") Above seems a cargo cult without paying attention to how ACPI IDs are being allocated.

The dmaengine buffer has some length alignment requirements that can differ from platform to platform. If the length alignment requirements are not met unexpected behavior like dropping of samples can occur. Currently these requirements are not reported and applications need to know the requirements of the platform by some out-of-band means. Add a new buffer attribute that reports the length alignment requirements called `length_align_bytes`. The reported length alignment is in bytes that means the buffer length alignment in sample sets depends on the number of enabled channels and the bytes per channel. Applications using this attribute to determine the buffer size requirements need to consider this. Signed-off-by:
