* i.MX6: nitrogen6x: force HDMI onto IPU0/DI0Eric Nelson2013-08-21-1/+2
| | | | | | | | | | | | Our Linux kernel switches the HDMI connector onto IPU0/DI1, but the U-Boot display driver only supports IPU0/DI0 for the time being. Because of this, a soft re-boot will leave the HDMI output connected to the wrong display port and prevent video from being displayed. Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com>

* | imx: nitrogen6x: mx6qsabrelite: Add support for DVI monitorsRobert Winkler2013-07-27-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A little background is probably appropriate for this patch. Since "the beginning" of usage of the SABRE Lite and Nitrogen6x boards, DVI detection has been somewhat broken. Some (most) DVI monitors don't produce the "HPD" bit in the PHY_STAT0 register, but do show proper toggling of the RX_SENSE0..3 bits. Creating a new the bit-mask to include all five bits and modifying the 'hdmidet' command and internal detection routines allows these monitors to function properly in U-Boot. A related patch to our kernels allows things to work under Linux: https://github.com/boundarydevices/linux-imx6/commit/7d8752905c118af9063738a533227de0b2f6ecd4 Signed-off-by: Robert Winkler <robert.winkler@boundarydevices.com> Acked-by: Stefano Babic <sbabic@denx.de>

* | mx6qsabrelite: Remove mx6qsabrelite code in favor of nitrogen6xFabio Estevam2013-07-26-0/+72
|/ | | | | | | | | | mx6qsabrelite and nitrogen6q boards are hardware compatible, so let's avoid the code duplication and only use the nitrogen6x source code to make board code maintainance easier. Tested booting a mainline device tree kernel on a mx6qsabrelite board. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
* ddr cfg: DRAM_RESET needs 0x00020030Troy Kisky2013-07-20-1/+1
| | | | | | | | | | | | | | | | | The old value of 0x000e0030 will cause ethernet timeout issues on the sabrelite and possibly other boards using the KSZ9021. I have no explanation as to why. But this is a correct change, the TRM will be updated to show that 00b is the only valid setting for bits 19-18 of DRAM_RESET. My thanks go to Liu Hui(Jason) for this information.

| * mx6: mx6qsabrelite/nitrogen6x: Remove incorrect setting of gpio CS signalAndrew Gabbasov2013-06-03-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The number of gpio signal is packed inside CONFIG_SF_DEFAULT_CS macro (shifted and or'ed with chip select), so it's incorrect to pass that macro directly as an argument to gpio_direction_output() call. Also, SPI driver sets the direction and initial value of a gpio, used as a chip select signal, before any actual activity happens on the bus. So, it is safe to just remove the gpio_direction_output call, that works incorrectly, thus making no effect, anyway.

* | imx: iomux-v3: Include PKE and PUE to pad control pull definitionsBenoît Thébaudeau2013-04-28-24/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PUE requires PKE to mean something, as do pull values with PUE, so do not compell users to explicitly use PKE and PUE everywhere. This is also what is done on Linux and what has already been done for i.MX51. By the way, remove some unused pad control definitions. There is no change of behavior. Note that SPI_PAD_CTRL was defined by several boards with a pull value, but without PKE or PUE, which means that no pull was actually enabled in the pad. This might be a bug in those boards, but this patch does not change the behavior, so it just removes the meaningless pull value from those definitions.

* | nitrogen6x: Setup CCM_CCOSR registerFabio Estevam2013-04-25-0/+11
|/ | | | | | | | | | | | CKO1 drives sgtl5000 codec clock on nitrogen boards and wandboard. Doing this setup in the bootloader will allow us to remove a lot of code in arch/arm/mach-imx/mach-imx6q.c from the mainline kernel. Also, according to Eric Nelson: "enabling the clock <in the bootloader> will remove squeal after an ungraceful reboot (watchdog) if hooked up to speakers."

* mx6: Fix get_board_rev() for the mx6 solo caseFabio Estevam2013-04-03-5/+0
| | | | | | | | | | | | | | | | | | When booting a Freescale kernel 3.0.35 on a Wandboard solo, the get_board_rev() returns 0x62xxx, which is not a value understood by the VPU (Video Processing Unit) library in the kernel and causes the video playback to fail. The expected values for get_board_rev are: 0x63xxx: For mx6quad/dual 0x61xxx: For mx6dual-lite/solo So adjust get_board_rev() accordingly and make it as weak function, so that we do not need to define it in every mx6 board file.

* mmc: i.MX6: fsl_esdhc: Define maximum bus width supported by a boardAbbas Raza2013-04-03-0/+3
| | | | | | | | | | | | | | | | | | Maximum bus width supported by some i.MX6 boards is not 8bit like others. In case where both host controller and card support 8bit transfers, they agree to communicate on 8bit interface while some boards support only 4bit interface. Due to this reason the mmc 8bit default mode fails on these boards. To rectify this, define maximum bus width supported by these boards (4bit). If max_bus_width is not defined, it is 0 by default and 8bit width support will be enabled in host capabilities otherwise host capabilities are modified accordingly. It is tested with a MMCplus card.
