You have to check this offset and the formula from the vendor kernel. For the calibration data this seems to be "0x01c1b240" : https://github.com/BPI-SINOVOIP/BPI-M2U-bsp/blob/cbfb10bffba398dd109262af9704fe70cb4b2f3e/linux-sunxi/drivers/soc/allwinner/sunxi-sid-efuse.h#L49 For the formula you have to check here: https://github.com/BPI-SINOVOIP/BPI-M2U-bsp/blob/cbfb10bffba398dd109262af9704fe70cb4b2f3e/linux-sunxi/drivers/thermal/sunxi_thermal/sun8iw11_ths.c#L65 And you can check a bit the dt bindings for IRQ and memory mapping here : https://github.com/BPI-SINOVOIP/BPI-M2U-bsp/blob/master/linux-sunxi/arch/arm/boot/dts/sun8iw11p1.dtsi#L1601-L1607 > > Hope this can help. > > Regards, > Clément > > > > > Thank you anyway. > > > > On Thursday, July 25, 2019 at 5:37:39 PM UTC-3, Clément Péron wrote: > >> > >> Hi Alex, > >> > >> On Thu, 25 Jul 2019 at 22:01, @lex <alex....@gmail.com> wrote: > >> > > >> > Thank you for the info. > >> > > >> > Almost there, i get negative values for the temp, still something > >> > missing or wrong. > >> > >> This mean that the calibration data are wrong. > >> > >> I don't know where the H3 is looking for his callibration data. > >> > >> But the R40 seems to have a register for that with an offset of 0x74: > >> Maybe you should try : > >> reg = <0x1c24c00 0x400>, > >> <0x1c24c74 0x4>; > >> > >> Else you have to open the H3 user manual and understand what this > >> "0x01c14234" address is pointing to. > >> And look for the same information for R40. > >> > >> Regards, > >> Clément > >> > >> > > >> > I came up with this: > >> > > >> >> ths: ths@1c24c00 { > >> >> #thermal-sensor-cells = <0>; > >> >> compatible = "allwinner,sun8i-h3-ths"; > >> >> reg = <0x1c24c00 0x400>, > >> >> <0x01c14234 0x4>; > >> >> reg-names = "ths", "calibration"; > >> >> interrupts = <GIC_SPI 36 IRQ_TYPE_LEVEL_HIGH>; > >> >> resets = <&ccu RST_BUS_THS>; > >> >> reset-names = "ahb"; > >> >> clocks = <&ccu CLK_BUS_THS>, <&ccu CLK_THS>; > >> >> clock-names = "ahb", "ths"; > >> >> }; > >> > > >> > > >> > On Thursday, July 25, 2019 at 4:28:07 PM UTC-3, Clément Péron wrote: > >> >> > >> >> Hi Alex, > >> >> > >> >> On Thu, 25 Jul 2019 at 19:12, @lex <alex....@gmail.com> wrote: > >> >> > > >> >> > Hi Clément, > >> >> > > >> >> > No. i did not read the R40 manual until now, Base address: 1c24c00 > >> >> > But how to find the correct interrupt number and the correct Mapping > >> >> > in the Manual?
