sunxi: Add sun5i support Add support for the Allwinner A13 and A10s SoCs also know as the Allwinner sun5i family, and the A13-OLinuXinoM A13 based and r7-tv-dongle A10s based boards. The only differences compared to the already supported sun4i and sun7i families are all in the DRAM controller initialization: -Different hcpr values -Different MBUS settings -Some other small initialization changes Signed-off-by: Henrik Nordstrom <henrik@henriknordstrom.net> Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Oliver Schinagl <oliver@schinagl.nl> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk> 2014-06-09 09:36:58 +00:00			`/*`

Kconfig: USB: Migrate CONFIG_USB_EHCI to CONFIG_USB_EHCI_HCD In order to be able to migrate the various SoC EHCI CONFIG options we first need to finish the switch from CONFIG_USB_EHCI to CONFIG_USB_EHCI_HCD.

sun5i: add USB EHCI settings Specific USB EHCI settings to be set for sun5i if CONFIG_USB_EHCI is enabled. Note we don't specify default VBUS gpio pins for sun5i since they vary too much from board to board.

sunxi: usb: Do not call phy_probe from hcd code The 2/3 usb-phys on the sunxi SoCs are really a single separate functional block, and are modelled as such in devicetree. So once we've moved all the sunxi usb code to the driver-model then phy_probe will be called once for the entire block from the driver-model enumeration code. Move to this now as this also avoids problems with phy_probe being called multiple times once we introduce ohci support. This also allows us to get rid of the sunxi_usb_phy_enabled_count variable as phy_probe now is guaranteed to be called only once. Since we're effectively rewriting the probe / remove functions, move them to the end of the file while we are at it, as that is the most logical place for them.

sunxi: Machine id hack to prevent loading buggy sunxi-3.4 kernels Right now U-Boot supports the CONFIG_OLD_SUNXI_KERNEL_COMPAT option, which makes it go out of its way in limiting the selection of PLL clock frequencies and PMIC voltages in order not to upset outdated buggy sunxi-3.4 kernel releases. And if the CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set, then booting such old kernels exhibits various failures at runtime. This is very user unfriendly, and there were already several incidents when people wasted their time being hit by these runtime failures and trying to debug them. The right solution is not to add hacks and workarounds to the mainline U-Boot, but to fix these bugs in the sunxi-3.4 kernel. And in fact, the updated sunxi-3.4 kernels already exist. Still we need to follow the 'Principle of Least Surprise' and U-Boot needs to ensure that the old buggy kernels are not getting happily booted when the CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set. And this patch addresses this particular issue. This patch makes U-Boot store the 'compatibility revision' number in the top 4 bits of the machine id and pass it to the kernel. The old buggy kernels will fail to load with a very much googlable error message on the serial console (the "r1 = 0x100010bb" part of it): "Error: unrecognized/unsupported machine ID (r1 = 0x100010bb)" This error message can be documented in the linux-sunxi wiki with proper explanations about how to resolve this situation and where to get the necessary bugfixes for the sunxi-3.4 kernel. The fixed sunxi-3.4 kernels implement a revision compatibility check and clear the top 4 bits of the machine id if everything is alright. By accepting the machine id with the bits 31:28 set to 1, the sunxi-3.4 kernel effectively certifies that it has the PLL5 clock speed and AXP209 DCDC3 voltage fixes applied. It is still possible to set the CONFIG_OLD_SUNXI_KERNEL_COMPAT option in U-Boot if the user desires to use an outdated unpatched sunxi-3.4 kernel.
