* mx6: remove SYS_SOC from board KconfigPeng Fan2015-09-13-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | Remove duplicated SYS_SOC Kconfig entry from board Kconfig, because we have this entry in arch/arm/cpu/armv7/mx6/Kconfig.

* imx: mx6: ddr init MMDC according to ddr_typePeng Fan2015-09-02-0/+1
| | | | | | | | | | | | | | | | | To i.MX6, DDR3 and LPDDR2 is supported, so rename function mx6_dram_cfg to mx6_ddr3_cfg and the original mx6_dram_cfg function only is a wrapper. The new reimplemented function mx6_dram_cfg only invokes mx6_ddr3_cfg when ddr_type is for DDR3. Later we can use ddr_type to initialize MMDC for LPDDR2. Initialize ddr_type for different boards which enable SPL.

* imx: clock support enet2 anatop clock supportPeng Fan2015-09-02-1/+1
| | | | | | | | | | | | | | | | To i.MX6SX/UL, two ethernet interfaces are supported. Add ENET2 clock support: 1. Introduce a new input parameter "fec_id", only 0 and 1 are allowed. To value 1, only i.MX6SX/UL can pass the check. 2. Modify board code who use this api to follow new api prototype.

* mx6cuboxi: Fix Ethernet PHY detection problemFabio Estevam2015-05-15-1/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mx6cuboxi sometimes fails to recognize the Ethernet PHY: Net: Phy 0 not found The explanation for this behavior comes from from Rabeeh Khoury: "The LED_ACT pin on the carrier-one boards had a pull down that forces the phy address to 0x0; where on CuBox-i and the production HummingBoard that pin is connected directly to LED that depending on the pull down strength of the LED it might be sampled as '0' or '1' thus the phy address might appear as either address 0x0 or 0x4." "This is AR8035 implementation; in reset stage the LED pin is configured as input, and pull up/down does matter. In this case it configures the PHY address. After reset is deasserted the same LED pin becomes output and then according to the previous pull/up it should be active high/low" One way to properly fix this behavior is to place external pull-up/down resistors in the LED line, but from a software standpoint we can fix it by telling phy_find_by_mask() to scan the PHY at addresses 0x0 and 0x4.

* mx6cuboxi: Add HDMI output supportFabio Estevam2015-05-15-1/+100
| | | | | | | | | | | | | | | | | | | | | | Add HDMI output using PLL5 as the source for the IPU clocks, and accurate VESA timings. These settings are based on the patch from Soeren Moch <smoch@web.de> submitted for the tbs2910 mx6 based board. It allows the display to work properly at 1024x768@60. This should make the hdmi output signal compatible with most if not all modern displays.
