[linux-sunxi] SPI in Linux 4.8.0-rc6: Weird dip in SCLK right when slave select goes low

Hello, when using SPI on Allwinner A20 with CPOL=1 and CPHA=1 with Linux 4.8.0-rc6 Psychotic Stoned Sheep I see a weird dip in the beginning (which also confuses the slave) on the SCLK line right when SSEL goes low - see attachment. The lines are, starting from the top, SCLK MOSI MISO SSEL.

[linux-sunxi] [PATCH v5 2/3] ASoC: sun4i-codec: Rename some sun7i-only registers

Some of the registers defined in the driver are only usable on the A20. Rename these registers. Signed-off-by: Danny Milosavljevic --- sound/soc/sunxi/sun4i-codec.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/sound/soc/sunxi/sun4i-codec.c

[linux-sunxi] [PATCH v5 0/3] ASoC: sun4i-codec: Distinguish sun4i from sun7i

ASoC: sun4i-codec: Introduce mechanism to detect sun7i and provide a different regmap different compared to sun4i Allwinner A10. The controls will be extended in a forthcoming patch - it is necessary to distinguish between sun4i and sun7i controls because they have different registers. Renamed

[linux-sunxi] [PATCH v5 3/3] ASoC: sun4i-codec: Add custom regmap configs

The A20 has a few extra registers that the A10 doesn't have. Therefore, use different regmaps for A10 as compared to A20. Signed-off-by: Danny Milosavljevic --- sound/soc/sunxi/sun4i-codec.c | 38 +++--- 1 file changed, 35 insertions(+), 3

[linux-sunxi] [PATCH v5 1/3] ASoC: sun4i-codec: Rename sun4i_codec_widgets for consistency

Re: [linux-sunxi] custom bootloader/OS + registers question + IPI

Andre, I took some time to answer because I documented myself further. I like to be precise. You are right, this is the bit I missed: the platform seeks for a sd card to boot before looking for the on board NAND. So, from here, I can add my bootloader on the sdcard and let the fun start (no
