[linux-sunxi] [PATCH v2 09/10] ARM: dts: sun8i: a83t: cubietruck-plus: Enable micro-SD card and eMMC

Now that we support the MMC controllers on the A83T SoC, we can enable them on some boards. Signed-off-by: Chen-Yu Tsai --- arch/arm/boot/dts/sun8i-a83t-cubietruck-plus.dts | 27 1 file changed, 27 insertions(+) diff --git

[linux-sunxi] [PATCH v2 02/10] clk: sunxi-ng: Add MP_MMC clocks that support MMC timing modes switching

All of our MMC clocks are of the MP clock type. A few MMC clocks on some SoCs, such as MMC2 on the A83T, support new/old timing mode switching. >From a clock rate point of view, when the new timing mode is active. the output clock rate is halved. This patch adds a special wrapper class of

[linux-sunxi] [PATCH v2 03/10] clk: sunxi-ng: a83t: Support new timing mode for mmc2 clock

The MMC2 clock supports a new timing mode. When the new mode is active, the output clock rate is halved. This patch sets the feature flag for the new timing mode, and adds a pre-divider based on the mode bit. Signed-off-by: Chen-Yu Tsai --- drivers/clk/sunxi-ng/ccu-sun8i-a83t.c

[linux-sunxi] [PATCH v2 07/10] ARM: dts: sun8i: a83t: Add MMC controller device nodes

The A83T has 3 MMC controllers. The third one is a bit special, as it supports a wider 8-bit bus, and a "new timing mode". Signed-off-by: Chen-Yu Tsai --- arch/arm/boot/dts/sun8i-a83t.dtsi | 59 +++ 1 file changed, 59 insertions(+) diff --git

The MMC controller can support DDR52 transfers under the new timing mode. According to the BSP kernel, the module clock has to be double the card clock, regardless of the bus width. The default timings in the hardware can be used. This also reworks the code setting the internal divider, getting

The third MMC controller (MMC2) on the Allwinner A83T SoC is slightly different. It supports a wider 8-bit bus, has a dedicated controllable reset pin for eMMC, and a "new timing mode" which is supposed to deliver better signals and thus better performance. Add a compatible for this one to use

[linux-sunxi] [PATCH v2 04/10] mmc: sunxi: Support controllers that can use both old and new timings

On the SoCs that introduced the new timing mode for MMC controllers, both the old (where the clock delays are set in the CCU) and new (where the clock delays are set in the MMC controller) timing modes are available, and we have to support them both. However there are two bits that control which

[linux-sunxi] [PATCH v2 01/10] clk: sunxi-ng: Add interface to query or configure MMC timing modes.

Starting with the A83T SoC, Allwinner introduced a new timing mode for its MMC clocks. The new mode changes how the MMC controller sample and output clocks are delayed to match chip and board specifics. There are two controls for this, one on the CCU side controlling how the clocks behave, and one

Hi everyone, This is v2 of my MMC controller support series. Changes since v1: - Fix patches already applied have been dropped - V2 now exports sunxi-ng mmc timing mode API functions (in case mmc driver is built as a module) - Added stub functions for the timing mode API functions,
