lib: crc_ccitt_false() is identical to crc_itu_t()

2023-12-29T20:22:26Z

crc_ccitt_false() was introduced in commit 0d85adb5fbd33 ("lib/crc-ccitt: Add CCITT-FALSE CRC16 variant"), but it is redundant with crc_itu_t(). Since the latter is more used, it is the one being kept.

mfd: cs42l43: Add support for cs42l43 core driver

2023-08-17T11:06:11Z

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 MFD component registers and initialises the device and provides PM/system power management.
