Pull i2c updates from Wolfram Sang: - mostly driver updates. Bigger ones for mlxcpld and iproc. But most of them are all over the place. - removal of the efm32, sirf, u300, and zte zx bus drivers because of platform removal. So, we have a pleasant diffstat this time. - first set of cleanups in the I2C core as preparation to increase maximum length of SMBus transfers to 255 (as specified in the new standard). Better documentation of struct i2c_msg and its flags stand out here. - the testunit can now respond to SMBus block process calls which is the testcase when implementing the above new maximum length. * 'i2c/for-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (62 commits) i2c: remove redundant error print in stm32f7_i2c_probe i2c: testunit: add support for block process calls i2c: busses: Replace spin_lock_irqsave with spin_lock in hard IRQ dt-bindings: eeprom: at24: Document ROHM BR24G01 i2c: i801: Add support for Intel Alder Lake PCH-P i2c: mv64xxx: Fix check for missing clock after adding RPM i2c: mux: mlxcpld: Add callback to notify mux creation completion i2c: mux: mlxcpld: Extend supported mux number i2c: mux: mlxcpld: Extend driver to support word address space devices i2c: mux: mlxcpld: Get rid of adapter numbers enforcement i2c: mux: mlxcpld: Prepare mux selection infrastructure for two-byte support i2c: mux: mlxcpld: Convert driver to platform driver i2c: imx: Synthesize end of transaction events without idle interrupts i2c: i2c-qcom-geni: Add shutdown callback for i2c i2c: mv64xxx: Add runtime PM support i2c: amd-mp2: Remove unused macro i2c: amd-mp2: convert to PCI logging functions i2c: mux: mlxcpld: Move header file out of x86 realm platform/x86: mlxcpld: Update module license i2c: mux: mlxcpld: Update module license ...
