i2c: imx_lpi2c: Support read transfers longer than 256 bytes

2024-08-09T12:46:49Z

The TXFIFO register of LPI2C only has one byte length, and if the length of the data that needs to be read exceeds 256 bytes, it needs to be written to TXFIFO multiple times. Signed-off-by: Fedor Ross

i2c: imx_lpi2c: Replace hard-coded bus speed value with bus->speed_hz

2024-08-09T12:46:49Z

Instead of using the hard-coded bus speed value I2C_SPEED_STANDARD_RATE, use the actual configured bus speed. This way the bus speed doesn't change suddenly after calling the imx_lpi2c_probe_chip() function for example. Signed-off-by: Fedor Ross

i2c: imx_lpi2c: Fix a typo in bus_i2c_receive

i2c: samsung: Support platforms other than EXYNOS4 and EXYNOS5

2024-08-09T12:46:05Z

Newer Samsung SoCs (including newer Exynos, ExynosAuto, Google Tensor) still use these IPs, or slightly newer versions of it. Make these drivers available on these platforms by guarding EXYNOS4/EXYNOS5 specific code behind their configs, and using CCF for clocks on other platforms. Tested S3C I2C driver on Exynos7885. This along with extended clock driver should enable S3C I2C on Exynos850. Signed-off-by: David Virag Tested-by: Henrik Grimler Reviewed-by: Heiko Schocher

i2c: mux: Fix error path in i2c-arb-gpio

2024-08-09T12:46:05Z

There is no reason to use goto and just call return. Better is to call return directly which is done for some if/else parts. Also make no sense to setup ret to -ETIMEDOUT and then to 0. Return timeout directly. Signed-off-by: Michal Simek Reviewed-by: Heiko Schocher
