This series adds a GPIO sysinfo driver using the dm_gpio_get_values_as_int_base3 function. The board revision is mapped based in devicetree properties. This series is based on Simon's GPIO series [1].

Changes in v3: - Fix assuming any nonzero return of dev_count_phandle_with_args was an error. - Fix assuming nonzero return from dm_gpio_get_values_as_int_base3 is an error. - Move detected bool into sysinfo_priv struct - Rebase onto u-boot/next - Use SYSINFO_ID_BOARD_MODEL instead of SYSINFO_ID_REVISION
Changes in v2: - Document sysinfo_gpio_priv - Enforce sysinfo detect ordering in uclass. Users must still call sysinfo_detect beforehand. - Fix unbalanced brace in sysinfo_gpio_get_int - Modify sysinfo test to check for detect() ordering. - Refactor driver to take advantage of the uclass detect ordering guarantee. - Reorder includes - Set BOARD_HWVERSION to SYSINFO_ID_REVISION, as they represent the same content. - Use enums instead of defines for sysinfo ids
Sean Anderson (5): dm: gpio: Fix gpio_get_list_count failing with livetree sysinfo: Use global sysinfo IDs for existing sysinfo drivers sysinfo: Require that sysinfo_detect be called before other methods sysinfo: Add gpio-sysinfo driver test: Add gpio-sysinfo test
