* pinctrl: qcom: qdf2xxx: drop ACPI_PTRKrzysztof Kozlowski2023-06-091-1/+1
| | | | | | | | | | | Driver can bind only via ACPI matching and acpi_device_id is there unconditionally, so drop useless ACPI_PTR() macro.

* pinctrl: qcom: qdf2xxx: add support for new ACPI HID QCOM8002Timur Tabi2018-05-021-41/+73
| | | | | | | | | | | | | | | | | | | | | | | | | Newer versions of the firmware for the Qualcomm Datacenter Technologies QDF2400 restricts access to a subset of the GPIOs on the TLMM. To prevent older kernels from accidentally accessing the restricted GPIOs, we change the ACPI HID for the TLMM block from QCOM8001 to QCOM8002, and introduce a new property "gpios". This property is an array of specific GPIOs that are accessible. When an older kernel boots on newer (restricted) firmware, it will fail to probe. To implement the sparse GPIO map, we register all of the GPIOs, but fill in the data only for available GPIOs. This ensures that the driver cannot accidentally access an unavailable GPIO. The pinctrl-msm driver also scans the "gpios" property to determine which pins are available, and ensure that only those can be registered. Support for QCOM8001 is removed as there is no longer any firmware that implements it.

| | | | | | | | | | The driver doesn't report an error message if the ACPI tables are missing the num-gpios property (which indicates how many GPIOs there are on this SOC), and it didn't check to ensure that the mallocs didn't fail.

* pinctrl: add support for Qualcomm Technologies QDF2xxx ARM64 SoCsTimur Tabi2015-07-171-0/+122
Add the pinctrl driver for the Qualcomm Technologies QDF2xxx ARM64 SoCs, which uses the Qualcomm Technologies TLMM pinctrl/gpio device. This driver is probed via ACPI and uses the pinctrl-msm.c backend driver. This driver is intended to be used only an ACPI-enabled system. As such, UEFI will handle all pin control configuration, so this driver does not provide pin control functions. It is effectively a GPIO-only driver.
