2023-08-21spi: stm32: fix accidential revert to byte-sized transfer splittingLeonard Göhrs
Commit 6f486556abe35 ("spi: stm32: renaming of spi_master into spi_controller") included an accidential reverted of a change added in commit 1e4929112507f ("spi: stm32: split large transfers based on word size instead of bytes"). This breaks large SPI transfers with word sizes > 8 bits, which are e.g. common when driving MIPI DBI displays. Fix this by using `spi_split_transfers_maxwords()` instead of `spi_split_transfers_maxsize()`.

2023-08-18Add cs42l43 PC focused SoundWire CODECMark Brown
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>: This patch chain adds support for the Cirrus Logic cs42l43 PC focused SoundWire CODEC.
2023-08-18spi: cs42l43: Add SPI controller supportLucas Tanure
The CS42L43 is an audio CODEC with integrated MIPI SoundWire interface (Version 1.2.1 compliant), I2C, SPI, and I2S/TDM interfaces designed for portable applications. It provides a high dynamic range, stereo DAC for headphone output, two integrated Class D amplifiers for loudspeakers, and two ADCs for wired headset microphone input or stereo line input. PDM inputs are provided for digital microphones. The SPI component incorporates a SPI controller interface for communication with other peripheral components.

2023-08-14spi: switch to use modern name (part2)Mark Brown
Merge series from Yang Yingliang <yangyingliang@huawei.com>: I'm trying to rename the legacy name to modern name used in SPI drivers, this is part2 patchset. After introducing devm_spi_alloc_host/spi_alloc_host(), the legacy named function devm_spi_alloc_master/spi_alloc_master() can be replaced. And also change other legacy name master/slave to modern name host/target or controller. All compile test passed.

Also, the return value from the call to platform_get_irq(pdev,0) is int and it is assigned to an unsigned int variable 'irq', thus redeclaring the type of variable 'irq' to signed int.
