+ * Driver for the Xtensa LX4 GPIO32 Option
+ *
+ * Documentation: Xtensa LX4 Microprocessor Data Book, Section 2.22
+ *
+ * GPIO32 is a standard optional extension to the Xtensa architecture core that
+ * provides preconfigured output and input ports for intra SoC signaling. The
+ * GPIO32 option is implemented as 32bit Tensilica Instruction Extension (TIE)
+ * output state called EXPSTATE, and 32bit input wire called IMPWIRE. This
+ * driver treats input and output states as two distinct devices.
+ *
+ * Access to GPIO32 specific instructions is controlled by the CPENABLE
+ * (Coprocessor Enable Bits) register. By default Xtensa Linux startup code
+ * disables access to all coprocessors. This driver sets the CPENABLE bit
+ * corresponding to GPIO32 before any GPIO32 specific instruction, and restores
+ * CPENABLE state after that.
+ *
+ * This driver is currently incompatible with SMP. The GPIO32 extension is not
+ * guaranteed to be available in all cores. Moreover, each core controls a
+ * different set of IO wires. A theoretical SMP aware version of this driver
+ * would need to have a per core workqueue to do the actual GPIO manipulation.
