+
+description: |
+ The RK3399 clock controller generates and supplies clock to various
+ controllers within the SoC and also implements a reset controller for SoC
+ peripherals.
+ Each clock is assigned an identifier and client nodes can use this identifier
+ to specify the clock which they consume. All available clocks are defined as
+ preprocessor macros in the dt-bindings/clock/rk3399-cru.h headers and can be
+ used in device tree sources. Similar macros exist for the reset sources in
+ these files.
+ There are several clocks that are generated outside the SoC. It is expected
+ that they are defined using standard clock bindings with following
+ clock-output-names:
+ - "xin24m" - crystal input - required,
+ - "xin32k" - rtc clock - optional,
+ - "clkin_gmac" - external GMAC clock - optional,
+ - "clkin_i2s" - external I2S clock - optional,
+ - "pclkin_cif" - external ISP clock - optional,
+ - "clk_usbphy0_480m" - output clock of the pll in the usbphy0
+ - "clk_usbphy1_480m" - output clock of the pll in the usbphy1

Subject: [PATCH] arm64: dts: rockchip: remove interrupt-names from iommu nodes
The iommu driver gets the interrupts by platform_get_irq(),
so remove interrupt-names property from iommu nodes.

Nodes with compatible "jedec,spi-nor" are now checked with
jedec,spi-nor.yaml and mtd.yaml. The pattern is now
"^flash(@.*)?$", so change that for the boards with a
Rockchip SoC.

ROC-RK3328-PC is the board inside the portable Firefly Station M1
Geek PC. As a redesign after the ROC-RK3328-CC, it uses TypeC as
power input and OTG port, embedded with eMMC 5.1 storage and a
SDIO WiFi/BT chip (RTL8723DS).
- Rockchip RK3328 SoC
- 2/4GB LPDDR3 RAM
- 16/32/64/128GB eMMC 5.1
- TF card slot
- USB 3.0 Port x 1, USB 2.0 Port x 1, TypeC Port x 1 (Power/OTG)
- HDMI
- Gigabit Ethernet
- WiFi: RTL8723DS
- Audio: RK3328
- Key: Power, Reset, Recovery
- LED: POWER, USER

ROCK Pi 4A+ board is the successor of ROCK Pi 4A board.
Differences to the original version are
- has RK3399 OP1 SoC revision
- has eMMC (16 or 32 GB) soldered on board (no changes required,
since it is enabled in rk3399-rock-pi-4.dtsi)
- dev boards have SPI flash soldered, but as per manufacturer response,
this won't be the case for mass production boards

Subject: [PATCH] arm64: dts: rockchip: add SPDIF node for ROCK Pi 4
Add a SPDIF audio-graph-card to ROCK Pi 4 device tree.
It's not enabled by default since all dma channels are used by
the (already) enabled i2s0/1/2 and the pin is muxed with GPIO4_C5
which might be in use already.
If enabled SPDIF_TX will be available at pin #15.

The rockpro64 had a fan node since

however it was never tied into the thermal driver for automatic control.
Add the links to the thermal node to permit the kernel to handle this
automatically.

Subject: [PATCH] arm64: dts: rockchip: Enable SFC for Odroid Go Advance
This enables the Rockchip Serial Flash Controller for the Odroid Go
Advance. Note that while the attached SPI NOR flash and the controller
both support quad read mode, only 2 of the required 4 pins are present.
The rx bus width is set to 2 for this reason, and tx bus width is set
to 1 for compatibility reasons.
