This patch series converts uses of the old GPIO API to the GPIO descriptor API. It also converts the GPIO driver to use the GPIO irqchip library GPIOLIB_IRQCHIP instead of repimplementing the same.
Changes in v6: - Patchset now contains two patches as the patch 1 has been accepted. - Changes mentioned in individual patches of the set. Changes in v5: - Drop the patch which uses gpiochip_get_data() in place of gpio_chip_to_gb_gpio_controller() as of now. - This is because it currently breaks the driver, since gpiochip_add() sets the data pointer to NULL. Changes in v4: - Changes mentioned in individual patches of the set. Changes in v3: - Combines the latest versions of the three greybus patches together in a patch series.
Nishad Kamdar (2): staging: greybus: arche-apb-ctrl.c: Switch to the gpio descriptor interface staging: greybus: arche-platform: Switch to the gpio descriptor interface

Use the gpiod interface instead of the deprecated old non-descriptor interface while continuing to ignore gpio flags from device tree in functions "deassert_reset()" and "assert_reset()" for now.
Reviewed-by: Johan Hovold johan@kernel.org Signed-off-by: Nishad Kamdar nishadkamdar@gmail.com --- Changes in v6: - Remove some unnecessary line breaks. Changes in v5: - Change the commit message. - Restore the names of the gpio device-tree properties without the "-gpio" suffix. Changes in v4: - Use gpiod_set_raw_value() for deassert_reset() and assert_reset() as gpiod_set_value() will change the sematics of these calls by taking any gpio flags into account. - Remove some unnecesssary line breaks. - Restore 'spi_en' gpio check in fw_flashing_seq() as it is currently optional. Changes in v3: - Add this patch in a patchset. Changes in v2: - Resolved compilation errors. --- drivers/staging/greybus/arche-apb-ctrl.c | 152 +++++++++-------------- 1 file changed, 61 insertions(+), 91 deletions(-)

Changes in v6:
- Patchset now contains two patches as the patch 1 has been accepted.
All three patches look good now, but since Greg picks these up directly and applies them to the staging tree, it is best if you submit all three patches (with my reviewed-by tag) in a series.
One last resend as v7?
Thanks again for doing this.
