[PATCH v2 0/5] Add TPU support for R-Car H3/M3-W/M3-N

[PATCH v2 0/5] Add TPU support for R-Car H3/M3-W/M3-N

[Cao Van Dong]

This series adds tpu support for r8a7795/r8a7796/r8a77965 SoCs.
Based on the renesas-drivers-2019-04-02-v5.1-rc3 tag of renesas-drivers tree.
For test, after booting, I found the device was registered in the booting log.

Could you clarify some details of this test.

Looking at the DTS patches I see 'status = "disabled";' for each
of the newly added devices. So I would not expect them to be probed
at run-time without some extra tweaking.

Test procedure:
   - Apply patch series "[PATCH 0/4] pinctrl: sh-pfc: r8a7795/6/65: Add 
TPU pins, groups and functions".
   - Make sure switches { SW29-[1-2] are switched off or SW31-[1-4] are 
switched off(only for Salvator-xs) }.
   - Enable TPU and pin control in DTS (salvator-x/xs.dtsi):

     +
     +&tpu {
     +       pinctrl-0 = <&tpu_pins>;
     +       pinctrl-names = "default";
     +
     +       status = "okay";
     +};
     +
     +&pfc {
     +       tpu_pins: tpu {
     +               groups = "tpu_to2", "tpu_to3";
     +               function = "tpu";
     +       };
     +};

   - Exercise userspace PWM control for pwm[2,3] of 
/sys/class/pwm/pwmchip1/ .
   - Inspect PWM signals on the input side of { CN29-[58,60] or 
SW31-[1,2] (only for Salvator-xs) } using an oscilloscope.

Thank you,
Dong

Thanks,

I have applied the dts patches for inclusion in v5.3 based on
a) Testing by Geert and yourself; and
b) A belief that the hardware is very similar on the SoCs covered
   by this patchset
