Hi everyone,
This is v3 of my A83T CCU series. This is for 4.13.
Changes since v2:
- Dropped patches "clk: Provide option to query hardware for clk phase"
and "clk: sunxi-ng: Add class of phase clocks supporting MMC new timing
modes".
- Dropped support for MMC new timing mode. This will be added later with
MMC support. The goal for this series is to get clk support for the A83t
in. This is long overdue.
- Explicitly include ccu_mux.h and select SUNXI_CCU_MUX
Changes since v1:
- Dropped two patches that were merged
- Added clk core flag to disable caching of clock phases
- Added support for multiple variable pre-dividers
- Merged "pll-periph-ahb1" pre-divider clock into "ahb1" clock
with multiple variable pre-dividers
- Introduced new class of phase clocks that return -ENOTSUPP
when the clock is in new timing mode
- Force mmc2 clock to new timing mode
- Added back mmc2 output and sample clocks
- Fixed bit ops for forcing audio PLL configuration
- Added requirement for "losc" clock in device tree binding
- Stripped leading 0 in device node name
- Updated subject prefixes for various patches
Patch 1 adds a compatible string for the A83T CCU to the sunxi-ccu
bindings.
Patch 2 adds support for multiple variable pre-dividers to the sunxi-ng
mux class.
Patch 3 adds the driver for the A83T CCU.
Patch 4 adds the CCU device nodes, and fixes up any existing clock
phandles in the dtsi, without using the macros.
Patch 5 sets the clock accuracy for the main oscillator.
Patch 6 is for the next -rc2, switch the clock indices from raw numbers
to macros we introduced with the driver. This will be updated if more
peripherals are introduced in the same cycle.
Let me know what you think.
Cover letter excerpt from v1:
This is yet another series that adds support for the A83T CCU.
The A83T CCU has a mix of new styled (like the A80) clocks at
old (like A3x) offsets. Some differences include:
- D1/D2 style PLL clocks
- divisible audio module clocks
- new timing mode for mmc2 module clock
