git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-mergewindow Code cleanup: A substantial code cleanup from Wolfram affects many drivers: - Removed dev_err() in case of timeout during i2c transfers, as timeouts are not considered errors and should not be treated as such. - For the same reason, 'timeout' variables have been renamed to 'time_left'. Other cleanups: - The viperboard driver now omits the "owner = THIS_MODULE" assignment. - Finally, we have eliminated the last remnants of I2C_CLASS_SPD: support for class-based devices has been completely removed from the mux-gpio driver. - In the ocore devices, a more standard use of ioport_map() for 8-bit I/O read/write operations has been implemented. - The mpc driver will be among the first i2c drivers and one of the first in the kernel to use the __free auto cleanup routine. - The designware driver now uses MODULE_DEVICE_TABLE() instead of MODULE_ALIAS() for better consistency with the ID table. - Added prefixes to the octeon register macros. - Fixed some checkpatch errors in the newly created i2c-viai2c-common.c file. Code refactoring: - The riic driver has refactored read/write operations to more flexibly support new platforms, laying the foundation for new SoC peculiarities. - In the i801 driver, a notifier callback has been created for muxed child segments. - The lpi2c driver now sets a clock rate during probe instead of continuously calling clk_get_rate(). - Improvements in the clock divisor logic to accommodate other clock frequencies. - Combined some common functionalities during initialization for the wmt driver and separated others that can be independently used by different drivers. Now, all the common functionalities are grouped in the i2c-viai2c-common.c file. - Improved the clock stretching mechanism in the newly created i2c-viai2c-common.c file, inherited from the previous i2c-wmt.c. Features added: - The octeon driver now includes watchdog timeout handling. - Added high-speed support for the octeon driver. Added support for: - R9A09G057 SoC in the riic driver. - Rapids-D I2C controller in the designware driver. - Cadence driver now also supports RISC-V architectures. - Added support to the WMT device as a separate driver using the newly created i2c-viai2c-common.c functionalities. - Added support for the Zhaoxin I2C controller. Some improvements in the bindings: - The pnx driver is converted to dtschema. - Added documentation for the Qualcomm SC8280XP.
2024-05-06i2c: synquacer: Fix an error handling path in synquacer_i2c_probe()Christophe JAILLET1-13/+7
If an error occurs after the clk_prepare_enable() call, it should be undone by a corresponding clk_disable_unprepare() call, as already done in the remove() function. As devm_clk_get() is used, we can switch to devm_clk_get_enabled() to handle it automatically and fix the probe. Update the remove() function accordingly and remove the now useless clk_disable_unprepare() call.

2024-05-06i2c: designware: Replace MODULE_ALIAS() with MODULE_DEVICE_TABLE()Andy Shevchenko2-4/+6
As Krzysztof Kozlowski pointed out the better is to use MODULE_DEVICE_TABLE() as it will be consistent with the content of the real ID table of the platform devices. While at it, drop unneeded and unused module alias in PCI glue driver as PCI already has its own ID table and automatic loading should just work.

Add Zhaoxin I2C controller driver. It provides the access to the i2c busses, which connects to the touchpad, eeprom, I2S, etc. Zhaoxin I2C controller has two separate busses, so may accommodate up to two I2C adapters. Those adapters are listed in the ACPI namespace with the IIC1D17 HID, and probed by a platform driver. The driver works with IRQ mode, and supports basic I2C features. Flags I2C_AQ_NO_ZERO_LEN and I2C_AQ_COMB_WRITE_THEN_READ are used to limit the unsupported access.

2024-05-06i2c: thunderx: Support for High speed modeSuneel Garapati3-25/+54
To support bus operations for high speed bus frequencies greater than 400KHZ following control bits need to be setup accordingly - hs_mode (bit 0) field in Mode register to switch controller between low-speed and high-speed frequency operating mode. - Setup clock divisors for desired TWSI bus frequency using FOSCL output frequency divisor (D): 0 - sets the divisor to 10 for low speed mode 1 - sets the divisor to 15 for high speed mode. The TWSI bus output frequency, in master mode is based on: TCLK = 100MHz / (THP + 2) FOSCL = FSAMP / (M+1)×D = TCLK / (2 ^ N × (M + 1) × 15) FSAMP = TCLK / 2 ^ N where, N is <2:0> and M is <6:3> of TWSI Clock Control Register D is 10 for low speed or 15 for HS_MODE With high speed mode support, HLC mode usage is limited to low speed frequency (<=400KHz) bus transfers in hardware.
