Looking at https://github.com/orangepi-xunlong/linux-orangepi and comparing drivers/clk/sunxi/clk-sun50iw[69].h, I see: /* PRCM Register List */ #define CPUS_CFG 0x0000 #define CPUS_APBS1_CFG 0x000C #define CPUS_APBS2_CFG 0x0010 -#define CPUS_TIMER_GATE 0x011C #define CPUS_TWDOG_GATE 0x012C -#define CPUS_PWM_GATE 0x013C -#define CPUS_UART_GATE 0x018C #define CPUS_TWI_GATE 0x019C #define CPUS_RSB_GATE 0x01BC #define CPUS_CIR_CFG 0x01C0 #define CPUS_CIR_GATE 0x01CC #define CPUS_OWC_CFG 0x01E0 #define CPUS_OWC_GATE 0x01EC #define CPUS_RTC_GATE 0x020C #define CPUS_CLK_MAX_REG 0x020C which suggests that TWD is still there, along with OWC/W1 and an undocumented RSB controller like the one in H6. Jernej, can you check RSB? It should be PL0/PL1 function 2 and MMIO base 0x7083000. Cheers, Samuel

I tested I2C and IR. What is your source for these > clocks? I poked around in this area, writing all Fs into those clock registers and checked which stuck. There are actually even more clocks still around there, though not all of the H6 (no PWM, for instance). For TWD: it's mentioned in the manual, the clock register is there and can be written to. The normal watchdog registers do not appear to work at 0x7020800 (they are RAZ/WI), but there is a counter at 0x7020820, which increments as long as those TWD clock gates are open. It stops when the clock bits are cleared. So that tells me that this clock is there and is working. I didn't have time yet to check the other (former) peripherals from that area.

Not sure what you mean, isn't that what I do? Having a separate sunxi_ccu_desc for each SoC and referencing separate structs? At least that's what I see in ccu-sun8i-v3s.c. What am I missing?
