The A10s and A13 have a few SRAM that can be mapped either to a device or to the CPU, with the mapping being controlled by a SRAM controller. Add the SRAM controller, the SRAM that it drives and the section that can be used by the various devices. Signed-off-by:

This patch reverts commit ccb4ada2 ("ARM: dts: sun7i: Add A20 SRAM and SRAM controller"), commit e6f51e4b ("ARM: dts: sun5i: Add A13 and A10s SRAM and SRAM controller") and commit 6d92b80f ("ARM: dts: sun4i: Add A10 SRAM and SRAM controller"). The bindings have been changed in the SRAM driver, and we need to change the DT accordingly. Signed-off-by:

On A80 there are 2 watchdogs, one in the main block, and one in the R (special) block. We do not have information on the R block watchdog, other than the register layout is the same, and the interrupt number. Both are able to reset the whole system. Add the main watchdog, in case the R block is used for special purposes like running an RTOS. Signed-off-by:

The BananaPro uses uart4 for the default rx/tx pins on the 40 pins connector, so enable uart4. Uart2 is also available at the bananapro io-pins, but like on the bananapi the primary function of the pins is to act as gpios, see: http://forum.lemaker.org/forum.php?mod=viewthread&tid=10852 Remove the uart2 node, people who want to use uart2 can do so with a devicetree-overlay.

The pinctrl groups for SPI until now were also adding the chip selects in the SPI pinctrl group. This was causing a few issues, since a board was forced to use a random number of chipselects, even though it might use one of these chip selects for another pin. The number of chipselects defined was also not the same from one group to another because of different needs at the time these groups have been introduced, resulting in no clear view from the board DTS on what exactly is being muxed, which even might change in the future. Solve this by creating different pinctrl groups for the chipselects and the standard SPI pins (CLK, MOSI and MISO) so that we fix both issues. Signed-off-by: -

A few lines (probably copy pasted) have an indentation mixing tabs and spaces that triggers a checkpatch warning. Fix those, and while we're at it, fix the space-indented sections. Signed-off-by: -

A few lines in our DTSIs are over the 80 characters limit, making checkpatch complain about that. If possible (and relevant), wrap these lines to 80 characters. Signed-off-by: -

The FSF address triggers a warning on checkpatch, saying that the FSF license is already present in the Linux source code, and that it has already changed in the past. Remove it from our DT, as suggested. Signed-off-by:

Currently none of the target boards nor the driver supports IR TX. However this pin is used in a few instances as a GPIO. Split the pin ctrl descriptions so that only the IR RX is configured to be used. Signed-off-by:

On sun6i we already have PLL6 as AHB1 clock's parent. However this was previously set in the dma controller node, which takes effect when the dma controller is probed. We want this to take effect as soon as possible, so hrtimer rate calculation is correct, and to be sure the AHB1 clock rate remains as stable as possible. Signed-off-by:

The clock driver now supports a muxable ahb clock. Update the dtsi with the proper compatible and add the new parent clocks. This also adds the new pll6/4 output for pll6 on sun7i-a20. The output is not used on sun4/5i. Also use assigned-clocks to reparent ahb to pll6. We want ahb to have a stable, non-changing clock rate. cpu/axi clock rate changes as a result of newly added cpufreq support. Signed-off-by:

The Jesurun Q5 has a black plastic casing with the approximate dimensions of 100mm x 100mm x 24mm with rounded edges. In terms of hardware it features an Allwinner A10 SoC with 1GB RAM and 8GB of NAND flash. The external connectors are: 2x USB-A female supporting USB2.0, 3.5mm female jack for audio, HDMI female, SPDIF, RJ45 LAN and Power. In addition the device has 1x red LED (hard wired to power) and an programmable green led. On the board there is also an unpopulated IR receiver and the UART. The devices is equipped with an AXP209 PMU. For more details see: http://linux-sunxi.org/Jesurun_Q5Signed-off-by:

The cpu core is clocked from the "cpu" clock. Add a reference to it in the first cpu node. Also add "cpu0" label to the node. The operating points were taken from the a list compiled by Maxime Ripard, which is based on A31 FEX files from the sunxi-boards repository. Not all boards have the same settings. The settings in this patch are the ones shared by A/B/C revisions, plus the default clock setting from u-boot. Signed-off-by:

Add UART aliases and stdout-path property for all the Allwinner boards so that we won't have to rely on the bootargs' console= value, while working with legacy bootloaders. While we're at it, also remove the mentions of earlyprintk in the bootargs, that will remove our default bootargs entirely, and allow the kernel to boot on a system even if DEBUG_LL is configured for another system.

Since the phy core already supports specifying a regulator to handle during power up/down, it was decided to drop the regulator support in the sun9i usb phy driver. This patch switches the DT to the core bindings. This and the phy driver would be in the same release and should not be a problem as far as DT stability goes. Signed-off-by:

Sometimes we need to specify non-probably information for sdio devices in the devicetree, this is done through child nodes addressed by the reg property, whereby the reg property refers to the sdio function number, see; Documentation/devicetree/bindings/mmc/mmc.txt This commit adds the necessary address- and size-cells properties to the mmc controller nodes in the dtsi files, so that dts files needing such a child node do not need to specify these themselves.

Add a Cubietech Cubieboard4 device tree and instruct make to build it. This device tree has been derived from the sun9i-a80-optimus.dts as they are very similar in design[1]. Notably, I2C3 is not used on Cubieboard4 and the LED/PWM definitions will need to be updated in the future. [1] http://dl.cubieboard.org/model/cc-a80/Hardware/CC-A80-HW-V1.1.pdfSigned-off-by:
