Hi everyone,
here's the the new version of CLK, RESET and PINCTRL drivers to
configure sunxi from the device-tree. This adds support for the
upstream CCU node (for reset and pinctrl) and tries to address the
various concerns people had.
Note that (to stay in sync with the Linux files), some of the
patches may not fully adhere to the style (e.g. some of the code
reused verbatim from Linux and in the config tables).
This has been tested with Ethernet, I2C, SPI and MMC on the A64-uQ7.
See my separate patchsets for the conversion of these drivers over
to support DM-based CLK, RESET and PINCTRL configuration.
Changes is v3:
* add support for the 'new-style' clock subsystem (CCU) by porting
from Linux and adding the necessary glue implementation
- add a CCU reset-driver (in addition to the legacy driver, which
will still be required for the R_* device nodes), which reuses
the reset-table from ccu-<SOC>.c
- add a clk-sunxi-ccu.c implementation based on Linux and reusing
both the low-level clock implementation (ccu_*.h) and the config
table (ccu-<SOC>.c) from Linux
* reuse the 'allwinner,pinctrl.txt' documentation for the pinctrl
binding from Linux
* adds the includes for the CCU dt-bindings from Linux
* adds support for printing the CCU subsystem via 'clk dump'
Philipp Tomsich (9):
