Subject: [PATCH 0/4] GPIO & Hierarchy IRQ support for HiFive Unleashed
Date: Tue, 12 Nov 2019 12:11:52 +0000 [thread overview]
Message-ID: <1573560684-48104-1-git-send-email-yash.shah@sifive.com> (raw)
This patch series adds GPIO drivers, DT documentation and DT nodes for
HiFive Unleashed board. The gpio patches are mostly based on Wesley's patch.
The patchset also adds hierarchy irq domain support as it is required by this
gpio driver.
This patchset is based on Linux 5.4-rc6 and tested on HiFive Unleashed board
Changes since RFC version:
Incorporated below changes as suggested by Linus Walleij on RFC version of this
patchset[0]
- Dropped PWM patches as they are already merged.
- Include "GPIO_GENERIC" and "REGMAP_MMIO" in Kconfig select option
- Remove unwanted inclusion of header files
- Use regmap MMIO instead of customised sifive_assign_bit()
- Use GPIOLIB_GENERIC and bgpio_init() to set up the accessors
- Use hierarchical irqdomain
