mfd: Add Renesas Synchronization Management Unit (SMU) support Add support for ClockMatrix(TM) and 82P33xxx families of timing and synchronization devices. The access interface can be either SPI or I2C. Currently, it will create 2 types of MFD devices, which are to be used by the corresponding rsmu character device driver and the PTP hardware clock driver, respectively.

mfd: rsmu: Support 32-bit address space We used to assume 0x2010xxxx address. Now that we need to access 0x2011xxxx address, we need to support read/write the whole 32-bit address space. Also defined RSMU_MAX_WRITE_COUNT and RSMU_MAX_READ_COUNT for readability Signed-off-by: Min Li <min.li.xe@renesas.com> Signed-off-by: Lee Jones <lee@kernel.org> Link: https://lore.kernel.org/r/MW5PR03MB693295AF31ABCAF6AE52EE74A08B9@MW5PR03MB6932.namprd03.prod.outlook.com 2023-03-27 18:39:53 +00:00			`#define RSMU_CM_SCSR_BASE 0x20100000`
