Pull spi updates from Mark Brown: "A moderately busy release for SPI, the main core update was the merging of support for multiple chip selects, used in some flash configurations. There were also big overhauls for the AXI SPI Engine and PL022 drivers, plus some new device support for ST.

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: intel-lpss: Fix the fractional clock divider flags

2023-12-13T16:19:08Z

The conversion to CLK_FRAC_DIVIDER_POWER_OF_TWO_PS uses wrong flags in the parameters and hence miscalculates the values in the clock divider. Fix this by applying the flag to the proper parameter.

mfd: da9062: Simplify obtaining I2C match data

2023-12-07T16:06:30Z

Simplify probe() by replacing of_device_get_match_data() and ID lookup for retrieving match data by i2c_get_match_data(). Some minor cleanups: * Remove the trailing comma in the terminator entry for the ID table making code robust against (theoretical) misrebases or other similar things where the new entry goes _after_ the termination without the compiler noticing. * Move OF table near to the user.
