* sunxi: Move usb-controller init code out of ehci-sunxi.c for reuse for otgHans de Goede2015-01-141-203/+10
| | | | | | | | | | Most of the usb-controller init code found in ehci-sunxi.c also is necessary to init the otg usb controller, so move it to a common place. While at it also update various #ifdefs / defines for sun8i support. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

| | | | | | | | | The axp221 / axp223's N_VBUSEN pin can be configured as an output rather then an input, add axp_drivebus_enable() and _disable() functions to set the pin in output mode and control it. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
* sunxi: axp221: Protect axp221_init against multiple callsHans de Goede2015-01-141-0/+6
| | | | | | | | | | | | | | | The voltage setting code knows it needs to call axp221_init before calling the various voltage setting functions. But users of axp utility functions like axp221_get_sid() do not know this, so the utility functions always call axp221_init() to ensure that the p2wi / rsb setup magic has been done. Since doing this repeatedly is quite expensive, add a check to axp221_init so that it only does the initialization once.

* sunxi: video: Add a hpd_delay parameter to configure hpd delayHans de Goede2015-01-141-4/+5
| | | | | | | | | | | | | In some extreme cases it may be necessary to wait 1.5 seconds or more for a hpd signal to show up (and be able to read edid info), but we do not want to penalize all headless boots with an extra second boot delay, so add a hpd_delay parameter which can be set through the video-mode env. variable. While at it raise the default from 300ms to 500ms as 300 may very well be too low in many cases. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

Also the A23 has the same reset bits (and necessity to enable the DRC block) as the sun6i, so enable those bits for sun8i too. Note building without HDMI support is useful for the A13 (sun5i variant) too, as that one does not have HDMI either.

* sunxi: gpio: Add support for gpio pins on the AXP209 pmicHans de Goede2015-01-142-0/+102
| | | | | | | | | | | | | | | | | | | | | | Some boards use GPIO-s on the pmic, one example of this is the A13-OLinuXino board, which uses gpio0 of the axp209 for the lcd-power signal. This commit adds support for gpio pins on the AXP209 pmic, the sunxi_gpio.c changes are universal, adding gpio support for the other AXP pmics (when necessary) should be a matter of adding the necessary axp_gpio_foo functions to their resp. drivers, and add "#define AXP_GPIO" to their header file. Note this commit only adds support for the non device-model version of the gpio code, patches for adding support to the device-model version are very welcome. The string representation for these gpio-s is AXP0-#, the 0 in the AXP0 prefix is there in case we need to support gpio-s on more then 1 pmic in the future. At least A80 boards have 2 pmics, and we may end up needing to support gpio-s on both. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

| | | | | | | | | | | | | | | | | | | Add a write to the "unknown" (*) register to enable auto input sync, when initially adding sunxi hdmi output support this magic write from the android kernel code was missed, causing lcdc -> hdmi encoder sync problems. With this write added, we can drop the modesetting retries and the extra delays added to work around these sync problems. With the retries dropped there also is no need to 0 all the enable flags at the beginning of the modeset, as they are initialized to 0 already by engines_init. *) "unknown" is the actual name of this register in the android kernel sources Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk> Acked-by: Anatolij Gustschin <agust@denx.de>

| | | | | | | | | | | | | When using a hdmi powered hdmi to vga dongle, and cold booting a sunxi device, the hpd detect code would not see the dongle (until a warm reboot), because the dongle needs some time to boot. Testing has shown that this dongle needs 213ms to respond on a cold boot, so wait up to 300ms for a hpd signal to show up before giving up.

* sunxi: video: Add hdmi supportHans de Goede2015-01-141-5/+61
| | | | | | | | | | | | | | | | | So far we've been programming the hdmi-encoder to send out dvi data over the hdmi connector. This works well for most devices, including hdmi devices, but not all devices accept dvi data on a hdmi input. Add support for sending proper hdmi data over the hdmi output found on most sunxi boards. This can be turned on by adding monitor=hdmi as option to the video-mode env. variable. A follow up patch will determine whether to send dvi or hdmi automatically when EDID is used.

| | | | | | | | | | | | | | | | The timings for the modes defined in videomodes.c differ (significantly) from vesa standard timings for these modes. This commit adds a version with the proper std timings for these modes, since I do not want to cause regressions, boards which want to use the standard timings need to define CONFIG_VIDEO_STD_TIMINGS to get the new correct timings. Since there is no std timing for 960x720 this commit uses the timing used by the nvidia video drivers for 960x720, which uses a standard pixelclock of 74.25 MHz rather then the weird 76.335... clock used by the old modes.

* videomodes: Add pixelclock_khz and refresh fields to ctfb_res_modesHans de Goede2015-01-142-7/+11
| | | | | | | | | | | | | | | | | | Add pixelclock_khz and refresh fields to ctfb_res_modes: 1) pixelclocks are usually referred to in hz, not picoseconds, and e.g pll-s are also typically programmed in hz, not ps. Converting between the 2 leads to rounding differences, add a pixelclock_khz field to directly store the *exact* pixelclock for a mode, so that drivers do not need to resort to rounding tricks to try and guess the exact pixelclock; 2) The video-mode environment variable, as parsed by video_get_video_mode also contains the vertical refresh rate, add a refresh field, so that the refresh-rate can be matched when parsing the video-mode environment variable.

* sunxi: mmc: Properly setup mod-clk and clock sampling phasesHans de Goede2015-01-141-27/+68
| | | | | | | | | | | | | | | | | | | | | | | The sunxi mmc controller has both an internal clock divider, as well as the divider in the mod0-clk for the mmc controller. The internal divider cannot be used, as it conflicts with the setting of clock sampling phases which is done in the mod0-clk, so it must be set to 0 (divide by 1). For some reason while the kernel has had this correct from day one, the u-boot sunxi mmc code has been using a fixed mod0-clk and setting its internal divider depending on the desired speed. This is something which we've inherited from the original Allwinner u-boot sources, but while this has been fixed in Allwinner's own u-boot code at least for the A23 and later upstream u-boot was still doing this wrong. This commit fixes this, thereby also fixing mmc support not working reliable on the A23 (which seems more sensitive to this) and possible also fixes some other sunxi mmc issues.
