2024-07-04mfd: idt8a340_reg: Start comments with '/*'Simon Horman1-4/+4
Several comments in idt8a340_reg.h start with '/**', which denotes the start of a Kernel doc, but are otherwise not Kernel docs. Resolve this conflict by starting these comments with '/*' instead.

2022-05-18ptp: ptp_clockmatrix: Add PTP_CLK_REQ_EXTTS supportMin Li1-1/+11
Use TOD_READ_SECONDARY for extts to keep TOD_READ_PRIMARY for gettime and settime exclusively. Before this change, TOD_READ_PRIMARY was used for both extts and gettime/settime, which would result in changing TOD read/write triggers between operations. Using TOD_READ_SECONDARY would make extts independent of gettime/settime operation Signed-off-by: Min Li <min.li.xe@renesas.com> Acked-by: Richard Cochran <richardcochran@gmail.com> Link: https://lore.kernel.org/r/1652712427-14703-1-git-send-email-min.li.xe@renesas.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2021-09-27ptp: clockmatrix: use rsmu driver to access i2c/spi busMin Li1-1/+30
rsmu (Renesas Synchronization Management Unit ) driver is located in drivers/mfd and responsible for creating multiple devices including clockmatrix phc, which will then use the exposed regmap and mutex handle to access i2c/spi bus.

2021-07-13mfd: Add Renesas Synchronization Management Unit (SMU) supportMin Li1-0/+729
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.
