* mx6cuboxi: Fix Ethernet PHY detection problemFabio Estevam2015-05-151-1/+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: Allow HDMI and USB keyboard to be stdout/stdinFabio Estevam2015-05-151-0/+7
| | | | | | | | | | | | | | | There are users of Cuboxi and Hummingboard that use these boards without connecting them to a USB/serial adapter. Allow such usage by allowing the HDMI port to act as stdout and USB keyboard as stdin. The serial console still also works as stdin/stdout.

| | | | | | | | | | | | | | | | | | | | | | 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.

* arm: mx6: Clamp MMDC and DDR3 clocks for timing calculationsNikolay Dimitrov2015-05-151-7/+23
| | | | | | | | | | | | | | | | This is proposal for clamping the MMDC/DDR3 clocks to the maximum supported frequencies as per imx6 SOC models, and for dynamically calculating valid clock value based on mem_speed. Currently the code uses impossible values for mem_speed (1333, 1600 MT/s) for calculating the DDR timings, and uses fixed clock (528 or 400 MHz) which doesn't take into account DDR3 memory limitations.

The regulator tests includes: - Regulator get by devname/platname - Voltage set/get - Current set/get - Enable set/get - Mode set/get - Autoset - List autoset For the regulator 'get' test, the returned device pointers are compared, and their names are also compared to the requested one. Every other test, first sets the given attribute and next try to get it. The test pass, when the set/get values are equal.

| | | | | | | | | | | | | | | This is the implementation of driver model PMIC driver. The max77686 PMIC driver implements read/write operations and driver bind method - to bind its childs. This driver will try to bind the regulator devices by using it's child info array with regulator prefixes and driver names. This should succeed when compatible regulator driver is compiled. If no regulator driver found, then the pmic can still provide read/write operations, and can be used with PMIC function calls.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Introduce a new structure `struct mxc_i2c_bus`, this structure will used for non-DM and DM. 2. Remove `struct mxc_i2c_regs` structure, but use register offset to access registers based on `base` entry of `struct mxc_i2c_bus`. 3. Remove most `#ifdef I2C_QUIRK_REG`. Using driver_data to contain platform flags. A new flag is introduced, I2C_QUIRK_FLAG. 4. Most functions use `struct mxc_i2c_bus` as one of the parameters. Make most functions common to DM and non-DM, try to avoid duplicated code. 5. Support DM, but pinctrl is not included. Pinmux setting is still set by setup_i2c, but we do not need bus_i2c_init for DM. 6. struct i2c_parms and struct sram_data are removed. 7. Remove bus_i2c_read bus_i2c_write prototype in header file. The frist paramter of bus_i2c_init is modified to i2c index. Add new prototype i2c_idle_bus and force_bus_idle. Since bus_i2c_init is not good for DM I2C and pinctrl is missed, we use a weak function for i2c_idle_bus. Board file take the responsibility to implement this function, like this: " int i2c_idle_bus(struct mxc_i2c_bus *i2c_bus) { if (i2c_bus->index == 0) force_bus_idle(i2c_pads_info0); else if (i2c_bus->index == 1) force_bus_idle(i2c_pads_info1); else xxxxxx } " 8. Introduce a weak function, enable_i2c_clk 9. Tested on an i.MX7 platform.

| | | | | | | | | | | | | | These GPIO_PORTx macros should be in gpio.h, but not in imx-regs.h. Also, imx-regs.h and iomux-v3.h has same macro defintion for GPIO_PORTx, and both of them are included in mxc_i2c.c(include mxc_i2c.h). This will incur build warnings with macro redefinition. Since iomux-v3.h is not compatible with mx27, we can not simply include iomux-v3.h for mx27, so move the GPIO_PORTx to gpio.h to fix the build warning.

* usb: ohci: Do not reuse ed for interrupt endpoints of different devicesHans de Goede2015-05-142-1/+38
| | | | | | | | | | | | | | | | | | | When submitting interrupt packets to an endpoint we only link in the ed once to avoid some races surrounding unlinking of periodic endpoints, but we share one ohci_device struct / one set of ed-s for all devices, which means that if we have an interrupt endpoint at endpoint 1 with one device, and a non interrupt endpoint 1 with another device we end up with the same ed linked into both the periodic and async lists, which is not good (tm). This commit switches over to using separate ohci_device structs, and thus separate ed-s for devices with interrupt endpoints, fixing this. This fixes e.g. matching a usb storage device and keyboard on the same usb-1 hub not working. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Marek Vasut <marex@denx.de>
