Fix GPIO operation of STMPE811 driver. Fixed issues: 1. STMPE811_GPIO_DIR was defined for register name and later was redefined to be the pin direction mask for `stmpe811_gpioconfig` I decided to change register name to be STMPE811_GPIO_DIR_REG, and keep pin direction mask STMPE811_GPIO_DIR, so that any external code that already use this driver will be unchanged. 2. The STMPE811 register GPIO_DIR uses bit value 1 for output and 0 for input, but `stmpe811_gpioconfig` set the opposite. 3. The call to `stmpe811_gpiowrite` from inside of `stmpe811_gpioconfig` leaded to deadlock. Approved-by: Gregory Nutt <gnutt@nuttx.org> |
