ARM: sunxi: Remove left-over cd-inverted property from pcDuino3

2018-01-10T06:07:09Z

Commit 8620f384098b ("dm: sunxi: Linksprite_pcDuino3: Correct polarity of MMC card detect") claims that the Pcduino3 device tree had an incorrect polarity for the card detect pin and thus changed the polarity flag of the cd-gpios from GPIO_ACTIVE_HIGH to GPIO_ACTIVE_LOW. Actually the DT was correct since according to the mmc binding, a combination of GPIO_ACTIVE_HIGH + cd-inverted results in an active-low polarity. But because the U-Boot driver lacks the code to look at the cd-inverted property (unlike the Linux driver) it interpreted the polarity of active-high. Thus, after that commit the DT is actually wrong from the binding/Linux point of view. To make both Linux and U-Boot interpret the DT in the same way, just drop the left-over cd-inverted property. I've sent a Linux patch to switch all sunxi DTs over to not using the cd-inverted property, so eventually all sunxi boards in U-Boot will be consistent in not using cd-inverted.

This is shown as active high in the schematics[1], so fix it. [1] https://patchwork.ozlabs.org/patch/777890/ Signed-off-by: Simon Glass Reported-by: Maxime Ripard

sunxi: Sync dts files with the upstream kernel

2016-03-23T21:04:13Z

Sync dts files with the upstream kernel including changes queued for 4.6: https://git.kernel.org/cgit/linux/kernel/git/mripard/linux.git/commit/?h=sunxi/dt-for-4.6 Note this adds a number of new unused board dts files. I've asked the authors of the kernel commits adding these to submit a matching defconfig to u-boot. Signed-off-by: Hans de Goede Acked-by: Ian Campbell

sunxi: Sync dts files with the linux kernel

2015-06-04T12:12:03Z

Copy over all the latest dts changes from mripard/sunxi/dt-for-4.2 , this gives us a proper dtsi file for the A33 rather then abusing sun8i-a23.dtsi for this. And this replaces our minimal (dummy) sun7i-a20-mk808c and sun8i-a33-astar-mid756 dts files with proper ones. Signed-off-by: Hans de Goede Acked-by: Ian Campbell

sunxi: dts: Sync all dts files with upstream kernel

2015-05-04T14:51:54Z

Bring all the sunxi dts files (and update existing ones) from mripard/sunxi/dt-for-4.1 (which will be merged into upstream master any day now). This is necessary so that we can move all sunxi boards over to the driver model. Signed-off-by: Hans de Goede Reviewed-by: Simon Glass Acked-by: Ian Campbell

dm: sunxi: Add support for serial using driver model

2014-11-05T12:09:58Z

Add a driver for the designware serial UART used on sunxi. This just redirects to the normal ns16550 driver. Add a stdout-path to the device tree so that the correct UART is chosen. Signed-off-by: Simon Glass Signed-off-by: Hans de Goede

These are from Linux 3.17-rc7 (commit fe82dcec). U-Boot only uses a small portion of these, but we may as well have something to look forward to. The total compiled size is about 25KB. Acked-by: Hans de Goede Signed-off-by: Simon Glass Signed-off-by: Hans de Goede
