* sunxi/nand: Add support to the SPL for loading u-boot from internal NAND memoryDaniel Kochmański2015-05-292-0/+69
| | | | | | | | | | | This commit adds support to the sunxi SPL to load u-boot from the internal NAND. Note this only adds support to access the boot partitions to load u-boot, full NAND support to load the kernel, etc. from the nand data partition will come later.

* sunxi: Make DRAM_ODT_EN Kconfig setting a boolHans de Goede2015-05-192-2/+2
| | | | | | | | | | | | | | | | | Make DRAM_ODT_EN Kconfig setting a bool, add a separate DRAM_ODT_CORRECTION setting for A23 SoCs and use DRAM_ODT_EN Kconfig everywhere instead of only in dram_sun4i.c and hardcoding odt_en elsewhere. Note this commit makes no functional changes for existing boards, its purpose is to allow changing the odt_en value on future A33 boards. For sun4i/sun5i/sun7i boards which set DRAM_ODT_EN=y (which no defconfigs currently do) this patch turns on odt for both the DQ and the DQS lines, whereas previously it was possibly (but not desirable) to turn odt on only for one of them by setting the in DRAM_ODT_EN option to 1 or 2 instead of 3.

* sunxi: usb: Do not call phy_probe from hcd codeHans de Goede2015-05-041-2/+2
| | | | | | | | | | | | | | | | | | | 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: axp: Move axp gpio code to a separate axpi-gpio driverHans de Goede2015-05-041-0/+13
| | | | | | | | | | | | | | | | | | | | Move the axp-gpio code out of the drivers/power/axp*.c code, and into a new separate axpi-gpio driver. This change drops supports for the gpio3 pin on the axp209, as that requires special handling, and no boards are using it. Besides cleaning things up by moving the code to a separate driver, as a bonus this change also adds support for the (non vusb) gpio pins on the axp221 and the gpio pins on the axp152. The new axp-gpio driver gets its own Kconfig option, and is only enabled on boards which need it. Besides that it only gets enabled in the regular u-boot build and not for the SPL as we never need it in the SPL.

| | | | | | | | | | | | | | | | | | | | | | | | | | sun6i and newer (derived) SoCs such as the sun8i-a23, sun8i-a33 and sun9i have a various things in common, like having separate ahb reset control registers, the SID living inside the pmic, custom pmic busses, new style watchdog, etc. This commit introduces a new hidden SUNXI_GEN_SUN6I Kconfig bool which can be used to check for these features avoiding the need for an ever growing list of "#if defined CONFIG_MACH_SUN?I" conditionals as we add support for more "new style" sunxi SoCs. Note that this commit changes the behavior of the gmac and hdmi code for sun8i and the upcoming sun9i devices. This does not matter as sun8i does not have gmac nor hdmi, and sun9i has new hardware-blocks for these so the old code will not work there. Also this is intentional as if a sun8i / sun9i variant which does use the old hwblocks shows up then the GEN_SUN6I code paths will be the right ones to use. For completeness this also adds a SUNXI_GEN_SUN4I bool for A10/A13/A20. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

| | | | | | | | | | | | | | | | | | | | Testing has shown that on sun4i the display backend engine does not have deep enough fifo-s causing flickering / tearing in full-hd mode due to fifo underruns.

As added advantage of this is that it results in much better memory bandwidth as it reduces the amount of dram bank switches, for more details see: http://ssvb.github.io/2014/11/11/revisiting-fullhd-x11-desktop-performance-of-the-allwinner-a10.html Note that this changes the pipeline searched for in the simplefb node, we can get away with doing this now, since no kernel has yet shipped with simplefb dtb nodes, and I will make sure to get a simplefb node with the new pipeline into 3.19 before it ships.

| | | | | | | | | | | | | | | | | | | | | | | | | | | While working on adding more boards I noticed that we lack a config for the 512M cubieboard, and that some of the new boards which I want to add also have 512M and 1G variants, rather then adding 2 defconfig's for all of these, lets switch the exising boards which have both a 512M and 1024M variant over to the sun4i dram autoconfig code. This also drops the foo_RAMSIZE_defconfig variants of boards where we currently have 2 separate configs already. Note: 1) The newly introduced CONFIG_DRAM_EMR1 kconfig value is not used with a value other then its default for now, but we need this to be configurable to support some new boards with auto dram config. 2) We always set all CONFIG_DRAM_foo values in defconfigs, even if they match the defaults, this is done to make it more clear what values are used for a certain board. This has been tested on a Mele A1000, Mini-X and a Cubieboard, all 1G variants, the dram autoconfig code has also been tested on a 512M mk802 (a defconfig for the mk802 is added in a later patch).

* sunxi: display: Make lcd display clk phase configurableHans de Goede2015-01-221-3/+1
| | | | | | | | | | | | | | | | | | | | While running some tests with an Olinuxino-A13-Micro + a 7" Olimex LCD module I noticed that the screen flickered. This is caused by the lcd display clk phase reg value being set to 0, where it should be 1 in this setup. This commit adds a Kconfig option for the lcd display clk phase, so that we can set it per board. This defaults to 1, because looking at all the fex files in sunxi-boards, that is by far the most used value. This commit updated the Ippo and MSI Primo73 tablet defconfigs to override the default of 1 with 0, as that is the correct value for those tablets, this keeps the register settings the same as before this commit. The Olinuxino-A13 defconfigs are not updated, changing the register setting for these boards from 0 to 1, this is intentional.

* sunxi: video: Modify sunxi_lcdc_pll_set to work with both tcon0 and tcon1Hans de Goede2015-01-141-0/+2
| | | | | | | | | | | | | Modify sunxi_lcdc_pll_set to work with both tcon0 and tcon1, this is a preparation patch for adding lcd support. While at it also swap the divider search order, searching from low to high, as the comment above the code says we should do. In cases where there are multiple solutions this will result in picking a lower pll clock and divider, which is more stable and saves power.
