Hi Simon,
Do you have plan to support interrupt controller driver for U-Boot?
On Rockchip SDK uboot，interrupt is enabled, usb driver using interrupt for speed up programing images.
U-Boot code has no a good interrupt controller driver platform, especially when u-boot using dtb.
So, I haven't a good idea if I want to upstream rockchip interrupt driver, do you have any suggestion?
Regards,
蔡文忠（CWZ）

Subject: [PATCH v4 00/33] dm: Introduce Rockchip RK3288 support
The Rockchip RK3288 is based on a quad-core Cortex-A17 CPU and has a good
set of peripherals. Various full-featured U-Boot ports are available and
this is an attempt to bring those features into mainline. With this series
the Firefly RK3288 can boot to a prompt from an SD card.
Since much of the code is generic, this also supports the Radxa Rock 2.
Since there is no device tree available for that yet, it uses the same
config and device tree as the Firefly. This works because not all
peripherals are supported, so the differences don't matter.
Support for booting from USB OTG is also provided, using the on-chip boot
ROM and the rkflashtool utility. This can boot as far as SPL, but there is
no support for reading U-Boot proper from USB as yet. This requires
implementing a suitable protocol (perhaps DFU or Rockchip's proprietary
one) in SPL.
Support is also provided for the Hisense Chromebook, which is based on the
same SoC. In this case it boots from SPI rather than an SD card.
This seriea makes use of driver model including a number of recently added
uclasses:
- Clocks - setting and getting PLL and peripheral clocks
- Pinctrl - adjusting pin multiplexing settings
- Reset - reseting the board or SoC
- RAM - setting up RAM controllers and detecting the available RAM
- MMC - MMC controllers (using the existing block device framework)
- LEDs - turning LEDs on and off, with only a GPIO driver so far
This series avoids hard-coding RK3288-specific code into the build. There
is a CONFIG_ROCKCHIP_RK3288 but it only *adds* support for RK3288. In
principle another CONFIG could add support for a different Rockchip SoC
with only the device tree selecting which one U-Boot works on.
Support is provided in mkimage to build these image types:
- rkimage - suitable for packaging up SPL to be sent to the boot ROM over
USB OTG
- rksd - suitable for writing to an SD card
Much of the source and ideas for this series came from downstream Rockchip
U-Boot trees. SDRAM init came from Coreboot. In most cases it has been
pretty heavily cleaned up / rewritten to meet U-Boot style and remove
hard-coding of things.
Drivers are provided for:
- Clocks
- Pinctrl
- SoC reset
- DDR3 SDRAM
- I2C
- SPI
- GPIOs
- LEDs using GPIOS
- MMC
- Firefly main PMIC (ACT8846) and included regulators
These are lightly tested and doubtless some problems exist with some,
particularly I2C.
One problem with device tree is that U-Boot has no way of dropping features
it does not need or use. For SPL this problem needs to be solved and this
series uses a new 'fdtgrep' tool for this. The 45KB Firefly device tree
reduces to a 6KB bytes when unused material is removed. SDRAM timings are
also in the device tree.
There is a large amount of additional work to bring other Rockchip drivers
and features into mainline U-Boot, so this is only a start.
Note: This series sits on top of Masahiro's RFC pinctrl series. I wanted to
get a new version out while we wait for this to make it to mainline. You can
find this series at u-boot-dm/rockchip-working.
Changes in v4:
- Add a set_state_simple() method
- Adjust the defconfig file to suit mainline
- Rename pinctrl.h to dm/pinctrl.h
- Tweak the cover letter a little, drop mention of patches already applied
- Use CONFIG_SPL_LED instead of CONFIG_SPL_LED_SUPPORT
Changes in v3:
- Add device tree bindings for CRU and DMC
- Add various new patches to get RK3288 booting to a prompt
- Make use of additional features since version 2
- Update README to mention available drivers
- Update clock rate to always be 24MHz
Changes in v2:
- Drop use of CONFIG_USE_PRIVATE_LIBGCC=y
- Tidy up license headers and remove SPL #ifdefs

dm: do not return pointer if NULL is given to devp of device_bind()
