2020-01-02clk: sunxi-ng: sun8i-r: Fix divider on APB0 clockSamuel Holland1-18/+3
According to the BSP source code, the APB0 clock on the H3 and H5 has a normal M divider, not a power-of-two divider. This matches the hardware in the A83T (as described in both the BSP source code and the manual). Since the A83T and H3/A64 clocks are actually the same, we can merge the definitions.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This round of clk driver and framework updates is heavy on the driver update side. The two main highlights in the core framework are the addition of an bulk clk_get API that handles optional clks and an extra debugfs file that tells the developer about the current parent of a clk. The driver updates are dominated by i.MX in the diffstat, but that is mostly because that SoC has started converting to the clk_hw style of clk registration. The next big update is in the Amlogic meson clk driver that gained some support for audio, cpu, and temperature clks while fixing some PLL issues. Finally, the biggest thing that stands out is the conversion of a large part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses less strings and more pointer comparisons to match clk parents and children up. In general, it looks like we have a lot of little fixes and tweaks here and there to clk data along with the normal addition of a handful of new drivers and a couple new core framework features.

2019-06-22clk: sunxi-ng: sun8i-r: Use local parent references for SUNXI_CCU_GATEChen-Yu Tsai1-14/+23
With the new clk parenting code and SUNXI_CCU_GATE macros, we can reference parents locally via pointers to struct clk_hw or DT clock-names. Convert existing SUNXI_CCU_GATE definitions to SUNXI_CCU_GATE_HWS as the parent clock is internal to this clock unit. To avoid duplication of clock definitions, we fix up the parent reference for A83T in the A83T init function.

With the new clk parenting code and CLK_FIXED_FACTOR_{HW,FW_NAME} macros, we can reference parents locally via pointers to struct clk_hw or DT clock-names. Convert existing CLK_FIXED_FACTOR definitions to either the _HW or _FW_NAME variant based on whether the parent clock is internal or external to the CCU.

2019-06-18clk: sunxi-ng: sun8i-r: Use local parent references for CLK_HW_INIT_*Chen-Yu Tsai1-40/+25
With the new clk parenting code and CLK_HW_INIT_* macros, we can reference parents locally via pointers to struct clk_hw or DT clock-names. Convert existing CLK_HW_INIT_* definitions to describe parents using either struct clk_hw pointers or clock-names from the device tree binding. For the AR100, this also allows us to merge the generic AR100 and the A83T specific one, which only differed in the global clock names for their parent clocks. The device tree bindings used the same name specifiers. Acked-by: Maxime Ripard <maxime.ripard@bootlin.com> Signed-off-by: Chen-Yu Tsai <wens@csie.org>

2017-06-07clk: sunxi-ng: a83t: Add support for A83T's PRCMChen-Yu Tsai1-0/+107
The A83T's PRCM has the same set of clocks and resets as the A64. However, a few dividers are different. And due to the lack of a low speed 32.768 kHz oscillator, a few of the clock parents are different.

2017-06-07clk: sunxi-ng: Support multiple variable pre-dividersChen-Yu Tsai1-5/+5
On the A83T, the AHB1 clock has a shared pre-divider on the two PLL-PERIPH clock parents. To support such instances of shared pre-dividers, this patch extends the mux clock type to support multiple variable pre-dividers. As the pre-dividers are only used to calculate the rate, but do not participate in the factorization process, this is fairly straightforward.
