A series of patches that add support for GPIO maps that have holes in them. That is, even though a client driver has N consecutive GPIOs, some are just unavailable for whatever reason, and the hardware should not be accessed for those GPIOs. Patch 1 reverts an old patch that triggers a get_direction of every pin upon init, without attempting to request the pins first. The direction is already being queried when the pin is requested. Patch 2 adds support to pinctrl-msm for "unavailable" GPIOs. Patch 3 extends that support to pinctrl-qdf2xxx. A recent ACPI change on QDF2400 platforms blocks access to most pins, so the driver can only register a subset. This version drops the availability check in gpiolib, because it's no necessary. Instead, just having pinctrl-msm return -EACCES is enough to block all unavailable GPIOs. Patch 1 removes the only instance where an unrequested GPIO is being accessed. v10: Use driver_stuct to obtain ACPI match table entry Timur Tabi (3): [v2] Revert "gpio: set up initial state from .get_direction()" [v8] pinctrl: qcom: disable GPIO groups with no pins [v6] pinctrl: qcom: qdf2xxx: add support for new ACPI HID QCOM8002 drivers/gpio/gpiolib.c | 31 ++------ drivers/pinctrl/qcom/pinctrl-msm.c | 28 +++++-- drivers/pinctrl/qcom/pinctrl-qdf2xxx.c | 134 +++++++++++++++++++++++++-------- 3 files changed, 133 insertions(+), 60 deletions(-) -- Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.
