AddU-Boot support for MediaTek SoCs - MT7623n & MT7629
Subsystems (11)
cover AddU-Boot support for MediaTek SoCs - MT7623n & MT7629
Hello,
This is the second round to add U-Boot support for MediaTek SoCs - MT7623n & MT7629, and the most of the drivers are based on mainline Linux, such as clock, timer, mmc, pinctrl, watchdog, power domain and device tree.
The following are the major differences between mainline Linux and U-Boot:
- Modify the drivers to adapt the U-Boot DM framework.
- Remove unneeded DT nodes as they don't have proper drivers in U-Boot yet.
- Just add the basic functions (step-by-step) so that we can monitor the size.
- Reuse UART driver ns16550.c but add a highspeed register for MediaTek chips.
Our current progress:
The MT7623n (BananaPi R2) which has already been supported in mainline Linux.
- Boot from eMMC or SD card.
- Boot flow: ROM -> MediaTek's preloder -> U-Boot ...
- An open development board called BananaPi R2 [1].
The MT7629 is NOT supported yet in mainline Linux, but I will add it soon.
- Boot from SNOR currently.
- Boot flow: ROM -> (boot header parsing sequence) -> SPL -> U-Boot ...
[1] http://wiki.banana-pi.org/Banana_Pi_BPI-R2
Current implementation was validated via the FIT image.
Thanks,
Ryder
Changes since v1:
- Fix new blank line at EOF and indentation.
- Revise commit message.
- Add missing sgmiisys device nodes.
- Add Tested-by tags from Matthias.
- Drop MT7629 qspi driver in the series, and we will implement another one based on the spi-mem framework.

PATCH 8/19 clk: MediaTek: add clock driver for MT7629 SoC.
In reply to Ryder LeeThis patch adds clock modules for MediaTek SoCs:
- Shared part: a common driver which contains the general operations for plls, muxes, dividers and gates so that we can reuse it in future.
- Specific SoC part: the group of structures used to hold the hardware configuration for each SoC.
We take MT7629 as an example to demonstrate how to implement driver if any other MediaTek chips would like to use it.

PATCH 12/19 pinctrl: MediaTek: add pinctrl driver for MT7629 SoC
In reply to Ryder LeeThis patch adds pinctrl support for MT7629 SoC. The IO core found on the SoC has the registers for pinctrl, pinconf and gpio mixed up in the same register range. Hence the driver also implements the gpio functionality through UCLASS_GPIO.
This also creates a common file as there might be other chips that use the same binding and driver, then being a little more abstract could help in the long run.

PATCH 14/19 power domain: MediaTek: add power domain driver for MT7629 SoC
In reply to Ryder LeeThis adds a power domain driver for the Mediatek SCPSYS unit.
The System Control Processor System (SCPSYS) has several power management related tasks in the system. The tasks include thermal measurement, dynamic voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control. The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power domain control.
For now this driver only adds power domain support.
