Hi, I turned GPIO support in bcma (CONFIG_BCMA_DRIVER_GPIO) and get this in log: bcma: bus0: Found chip with id 0xA8D8, rev 0x01 and package 0x0A bcma: bus0: Core 0 found: ChipCommon (manuf 0x4BF, id 0x800, rev 0x22, class 0x0) bcma: bus0: Core 1 found: IEEE 802.11 (manuf 0x4BF, id 0x812, rev 0x17, class 0x0) bcma: bus0: Core 2 found: PCIe (manuf 0x4BF, id 0x820, rev 0x0F, class 0x0) bcma: bus0: Found rev 6 PMU (capabilities 0x108C2606) bcma: bus0: SPROM offset 0x830 bcma: bus0: PMU resource config unknown or not needed for device 0xA8D8 gpiochip_add: gpios -1..14 (bcma_gpio) failed to register bcma: bus0: Error registering GPIO driver: -28 bcma: bus0: Bus registered bcma: bus1: Found chip with id 0x4313, rev 0x01 and package 0x08 bcma: bus1: Core 0 found: ChipCommon (manuf 0x4BF, id 0x800, rev 0x24, class 0x0) bcma: bus1: Core 1 found: IEEE 802.11 (manuf 0x4BF, id 0x812, rev 0x18, class 0x0) bcma: bus1: Core 2 found: PCIe (manuf 0x4BF, id 0x820, rev 0x11, class 0x0) bcma: bus1: Found rev 8 PMU (capabilities 0x084C3008) bcma: bus1: SPROM offset 0x830 gpiochip_add: gpios -1..14 (bcma_gpio) failed to register bcma: bus1: Error registering GPIO driver: -28 bcma: bus1: Bus registered bcma: bus2: Found chip with id 0x4313, rev 0x01 and package 0x08 bcma: bus2: Core 0 found: ChipCommon (manuf 0x4BF, id 0x800, rev 0x24, class 0x0) bcma: bus2: Core 1 found: IEEE 802.11 (manuf 0x4BF, id 0x812, rev 0x18, class 0x0) bcma: bus2: Core 2 found: PCIe (manuf 0x4BF, id 0x820, rev 0x11, class 0x0) bcma: bus2: Found rev 8 PMU (capabilities 0x084C3008) bcma: bus2: SPROM offset 0x830 gpiochip_add: gpios -1..14 (bcma_gpio) failed to register bcma: bus2: Error registering GPIO driver: -28 bcma: bus2: Bus registered does that mean that gpio is not usable? what might be the problem?
