+Subject: [PATCH] work-around: aspeed-bmc-opp-palmetto: Add GPIO hogs to
+ devicetree
+
+This is a work-in-progress patch that attempts to emulate the GPIO
+state originally written by the mach-aspeed board file.
+
+It isn't entirely analogous: Whilst values might be set in the GPIO
+data/direction registers, this doesn't mean the GPIO IP was in control
+of the pins affected by the bits in question. However, the content of
+the patch is derived directly from the data and direction values that
+Steve Faure reported[1] from a Palmetto running the OpenBMC stable branch.
+
+Secondly, the patch pays no regard to the prescribed active state of the lines
+and assumes active high for all pins. This is not a reflection of the
+description in the schematic, and neither do the configured GPIO values
+necessarily reflect the prescribed initial values from the schematic.
+
+A starting point for the patch was generated from the following Python script:
+
+	 #!/usr/bin/python3
+	 import sys
+
+	 from collections import namedtuple
+
+	 GpioRegsetConfig = namedtuple("GpioRegsetConfig", "banks value direction")
+	 banks = ( "ABCD", "EFGH" )
+
+	 broken = (
+		 GpioRegsetConfig(banks[0], 0x130F8CE3, 0x01706074),
+		 GpioRegsetConfig(banks[1], 0x9F48F7FF, 0x00004002)
+	 )
+
+	 working = (
+		 GpioRegsetConfig(banks[0], 0x130F8CE3, 0x0370E677),
+		 GpioRegsetConfig(banks[1], 0x0370E677, 0xC738F202)
+	 )
+
+	 GpioConfig = namedtuple("GpioConfig", "bank index direction state active")
+
+	 def gpio_dt(name, config):
+	     fmt = "pin_gpio_{} {{\n\tgpio-hog;\n\tgpios = <ASPEED_GPIO({}, {}) {}>;\n\t{};\n\tline-name = \"{}\";\n}};"
+	     if "output" == config.direction:
+		 state = "{}-{}".format(config.direction, config.state)
+	     else:
+		 state = config.direction
+	     return fmt.format(
+		 name.lower(),
+		 config.bank,
+		 config.index,
+		 "GPIO_ACTIVE_HIGH",
+		 state,
+		 name)
+
+	 def tell_gpios(config, change):
+	     for i, bank in enumerate(config.banks):
+		 for j in range(0, 8):
+		     bi = i * 8 + j;
+		     if ((1 << bi) & change) > 0:
+			 gpio = "{}{}".format(bank, j)
+			 if (bi & config.direction) > 0:
+			     sd = "output"
+			     value = "high" if (bi & config.value) > 0 else "low"
+			 else:
+			     sd = "input"
+			     value = None
+			 dtconfig = GpioConfig(bank, j, sd, value, "GPIO_ACTIVE_HIGH")
+			 print(gpio_dt(gpio, dtconfig))
+			 print()
+
+	 def main():
+	     for b, w in zip(broken, working):
+		 cd = b.direction ^ w.direction
+		 tell_gpios(w, cd)
+
+	 if __name__ == "__main__":
+	     main()
+
+The generated patch was tested on a Pass 2 Palmetto. It was found that with the
+patch and an OpenBMC userspace generated at v1.99.0-60-g2b717d8489c1, the host
+could:
+
+* Boot to Petitboot
+* Reboot to Petitboot
+* Survive a reboot of the BMC (remain functional at the Petitboot shell)
+* Be powered off by the BMC after reboot
+
+Reports from Andrew Geissler[2] and Cédric Le Goater[3] suggest mixed results
+across the Palmetto fleet, but this patch at least represents a step forwards.
+
+For the above reasons and those below, this patch is a temporary work-around:
+
+* GPIOs configured as hogs cannot have their line state changed once initialised
+* GPIOs configured as hogs will not be exposed to userspace even if requested
+
+These two issues combined deny capabilities such as Cronus. The ultimate
+solution is userspace daemon(s) requesting and controlling the GPIOs as
+desired.
