2025-06-19clk: renesas: Add CPG/MSSR support to RZ/N2H SoCLad Prabhakar
Add clock driver support for the Renesas RZ/N2H (R9A09G087) SoC by reusing the existing RZ/T2H (R9A09G077) CPG/MSSR implementation, as both SoCs share the same clock and reset architecture.

2024-11-06clk: renesas: vbattb: Add VBATTB clock driverClaudiu Beznea
The VBATTB IP of the Renesas RZ/G3S SoC controls the clock that is used by the RTC. The input to the VBATTB could be a 32KHz crystal or an external clock device. The HW block diagram for the clock generator is as follows: +----------+ XC `\ RTXIN --->| |----->| \ +----+ VBATTCLK | 32K clock| | |----->|gate|-----------> | osc | XBYP | | +----+ RTXOUT --->| |----->| / +----------+ , After discussions w/ Stephen Boyd the clock tree associated with this hardware block was exported in Linux as: vbattb-xtal xbyp xc mux vbattbclk where: - input-xtal is the input clock (connected to RTXIN, RTXOUT pins) - xc, xbyp are mux inputs - mux is the internal mux - vbattclk is the gate clock that feeds in the end the RTC to allow selecting the input of the MUX though assigned-clock DT properties, using the already existing clock drivers and avoid adding other DT properties. If the crystal is connected on RTXIN, RTXOUT pins the XC will be selected as mux input. If an external clock device is connected on RTXIN, RTXOUT pins the XBYP will be selected as mux input. The load capacitance of the internal crystal can be configured with renesas,vbattb-load-nanofarads DT property.

These become a maintenance burden now, so our development group decided to remove upstream support for this SoC. Public users only have ES2 onwards.

2018-09-11clk: renesas: cpg-mssr: Add R7S9210 supportChris Brandt
Add support for the R7S9210 (RZ/A2) Clock Pulse Generator and Module Standby. The Module Standby HW in the RZ/A series is very close to R-Car HW, except for how the registers are laid out. The MSTP registers are only 8-bits wide, there are no status registers (MSTPSR), and the register offsets are a little different. Since the RZ/A hardware manuals refer to these registers as the Standby Control Registers, we'll use that name to distinguish the RZ/A type from the R-Car type.
