[linux-sunxi] [PATCH 2/6] net: sun8i-emac: use new, generic GPIO setup routine

Instead of open-coding the fairly generic pinmux setup in the sun8i-emac driver, let's just use the new common implementation of that. This has also the advantage of supporting the newpinctrl bindings, so the driver can cope with the upstream Linux DTs. Signed-off-by: Andre Przywara

[linux-sunxi] [PATCH 0/6] sunxi: update Pine64/A64 DTs

Hi, in the wake of the sunxi DM enablement series it became apparent that the current device tree files for the A64 SoC and its board are outdated. Since Linux v4.10-rc1 there are now basic .dts files for the Allwinner A64 SoC and the Pine64 boards in the mainline kernel. Linux v4.11-rc1 added

[linux-sunxi] [PATCH 1/6] sunxi: GPIO: introduce sunxi_gpio_setup_dt_pins()

Instead of hard-coding GPIO pins used for a certain peripheral, we should just use the pinctrl information from the DT. The sun8i-emac driver has some simple implementation of that, so let's just generalize this and move the code into a more common location. On the way we add support for the new,

[linux-sunxi] [PATCH 5/6] sunxi: dts: remove now obsolete pine64-common.dtsi

Now since the common DT nodes between the two Pine64 boards have been moved into the .dts for the non-plus model, we no longer need the extra -common.dtsi. Let's just remove it. Signed-off-by: Andre Przywara --- arch/arm/dts/sun50i-a64-pine64-common.dtsi | 93

[linux-sunxi] [PATCH 4/6] sunxi: dts: update Pine64 .dts

Update the two .dts files for the Pine64 boards with those used in the kernel. This switches from using a -common.dtsi to including the .dts for the non-plus model in the -plus file. Again we keep our EMAC driver nodes in, which are not yet in mainline Linux. Signed-off-by: Andre Przywara

[linux-sunxi] [PATCH 3/6] sunxi: dts: update sun50i-a64.dtsi from Linux

Now with USB and MMC for the A64 supported in mainline Linux, let's sync our DT with what's in the official Linux repository. This completely changes the clock representation, but U-Boot doesn't use this anyway. Also it switches to a new pinctrl binding, which uses generic property names. The only

[linux-sunxi] [PATCH 6/6] sunxi: dts: add Bananapi M64 .dts

Since mainline Linux gained support for the BananaPi-M64, let's just copy this DT to prepare the U-Boot support for that board. Again add the required DT nodes for the Ethernet IP. Signed-off-by: Andre Przywara --- arch/arm/dts/Makefile| 3 +-

[linux-sunxi] [PATCH v4 2/3] nvmem: sunxi-sid: add support for H3's SID controller

The H3 SoC have a bigger SID controller, which has its direct read address at 0x200 position in the SID block, not 0x0. Also, H3 SID controller has some silicon bug that makes the direct read value wrong at cold boot, add code to workaround the bug. (This bug has already been fixed on A64 and

[linux-sunxi] [PATCH v4 1/3] nvmem: sunxi-sid: read NVMEM size from device compatible

Sometimes the SID device have more memory address space than the real NVMEM size (for the registers used to read/write the SID). Fetch the NVMEM size from device compatible, rather than the memory address space's length, in order to prepare for adding some registers-based read support.

Re: [linux-sunxi] Toggeling LDO3 causes crash/shutdown of the AXP209. Some verification help needed.

Hi again, more experiments with LDO3: If I set the voltage of LDO3 to the minimum value (0.7V): => i2c mw 0x34 0x29 0x0 then I can toggle LDO3 on and off without the AXP shutting down. Even increasing LDO3 voltage after it's been enabled works without problems: => i2c mw 0x34 0x12 0x57 => i2c
