move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

Bluetooth: btmtk: move btusb_mtk_hci_wmt_sync to btmtk.c

2024-07-15T14:11:46+00:00

Move btusb_mtk_hci_wmt_sync from btusb.c to btmtk.c which holds vendor specific stuff and would make btusb.c clean. Add usb.h header to btmtksdio.c/btmtkuart.c for usb related element defined in btmtk.h Signed-off-by: Sean Wang Signed-off-by: Chris Lu Signed-off-by: Luiz Augusto von Dentz

treewide, serdev: change receive_buf() return type to size_t

2024-01-28T02:13:53+00:00

receive_buf() is called from ttyport_receive_buf() that expects values ">= 0" from serdev_controller_receive_buf(), change its return type from ssize_t to size_t. The need for this clean-up was noticed while fixing a warning, see commit 94d053942544 ("Bluetooth: btnxpuart: fix recv_buf() return value"). Changing the callback prototype to return an unsigned seems the best way to document the API and ensure that is properly used. GNSS drivers implementation of serdev receive_buf() callback return directly the return value of gnss_insert_raw(). gnss_insert_raw() returns a signed int, however this is not an issue since the value returned is always positive, because of the kfifo_in() implementation. gnss_insert_raw() could be changed to return also an unsigned, however this is not implemented here as request by the GNSS maintainer Johan Hovold.

Bluetooth: btmtkuart: fix recv_buf() return value

2023-12-22T17:58:35+00:00

Serdev recv_buf() callback is supposed to return the amount of bytes consumed, therefore an int in between 0 and count. Do not return negative number in case of issue, just print an error and return count. This fixes a WARN in ttyport_receive_buf().

tty: serdev: convert to u8 and size_t

2023-12-08T11:02:38+00:00

Switch character types to u8 and sizes to size_t. To conform to characters/sizes in the rest of the tty layer. This patch converts struct serdev_device_ops hooks and its instantiations.

bluetooth: Explicitly include correct DT includes

2023-08-11T18:50:24+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

Bluetooth: btmtkuart: fix the conflict between mtk and msft vendor event

2022-03-18T16:12:07+00:00

There is a conflict between MediaTek wmt event and msft vendor extension logic in the core layer since 145373cb1b1f ("Bluetooth: Add framework for Microsoft vendor extension") was introduced because we changed the type of mediatek wmt event to the type of msft vendor event in the driver. But the purpose we reported mediatek event to the core layer is for the diagnostic purpose with that we are able to see the full packet trace via monitoring socket with btmon. Thus, it is harmless we keep the original type of mediatek vendor event here to avoid breaking the msft extension function especially they can be supported by Mediatek future devices.
