mfd: intel_quark_i2c_gpio: Convert GPIO to use software nodes

2021-08-11T13:00:53+00:00

The driver can provide a software node group instead of passing legacy platform data. This will allow to drop the legacy platform data structures along with unifying a child device driver to use same interface for all property providers, i.e. Device Tree, ACPI, and board files.

gpio: dwapb: Unify ACPI enumeration checks in get_irq() and configure_irqs()

2021-08-11T12:56:43+00:00

Shared IRQ is only enabled for ACPI enumeration, there is no need to have a special flag for that, since we simple can test if device has been enumerated by ACPI. This unifies the checks in dwapb_get_irq() and dwapb_configure_irqs(). Signed-off-by: Andy Shevchenko Acked-by: Lee Jones Acked-by: Serge Semin Tested-by: Serge Semin

mfd: intel_quark_i2c_gpio: Don't play dirty trick with const

2021-04-14T15:06:35+00:00

As Linus rightfully noticed, the driver plays dirty trick with const, i.e. it assigns a place holder data structure to the const field in the MFD cell and then drops the const by explicit casting. This is not how it should be. Assign local pointers of the cell and resource to the respective non-const place holders in the intel_quark_i2c_setup() and intel_quark_gpio_setup().
