+
+description: |
+ Pinmux and pinconf controller in the T-Head TH1520 RISC-V SoC.
+
+ The TH1520 has 3 groups of pads each controlled from different memory ranges.
+ Confusingly the memory ranges are named
+ PADCTRL_AOSYS -> PAD Group 1
+ PADCTRL1_APSYS -> PAD Group 2
+ PADCTRL0_APSYS -> PAD Group 3
+
+ Each pad can be muxed individually to up to 6 different functions. For most
+ pads only a few of those 6 configurations are valid though, and a few pads in
+ group 1 does not support muxing at all.
+
+ Pinconf is fairly regular except for a few pads in group 1 that either can't
+ be configured or has some special functions. The rest have configurable drive
+ strength, input enable, schmitt trigger, slew rate, pull-up and pull-down in
+ addition to a special strong pull up.
+
+ Certain pads in group 1 can be muxed to AUDIO_PA0 - AUDIO_PA30 functions and
+ are then meant to be used by the audio co-processor. Each such pad can then
+ be further muxed to either audio GPIO or one of 4 functions such as UART, I2C
+ and I2S. If the audio pad is muxed to one of the 4 functions then pinconf is
+ also configured in different registers. All of this is done from a different
+ AUDIO_IOCTRL memory range and is left to the audio co-processor for now.

+ * Limitations:
+ * - The THEAD_PWM_CTRL_START bit is only effective when 0 -> 1, which is used
+ * to start the channel, 1 -> 0 doesn't change anything. so 0 % duty cycle
+ * is used to "disable" the channel.
+ * - The THEAD_PWM_CTRL_START bit is automatically cleared once PWM channel is
+ * started.
+ * - The THEAD_PWM_CFG_UPDATE atomically updates and only updates period and duty.
+ * - To update period and duty, THEAD_PWM_CFG_UPDATE needs to go through 0 -> 1
+ * step, I.E if THEAD_PWM_CFG_UPDATE is already 1, it's necessary to clear it
+ * to 0 beforehand.
+ * - Polarity can only be changed if never started before.
