sunxi: rsb: Move rsb_set_device_mode() call to rsb_init()

2015-02-02T12:55:14Z

It turns out that the device_mode_data is rsb specific, rather then slave specific, so integrate the rsb_set_device_mode() call into rsb_init(). Signed-off-by: Hans de Goede Acked-by: Ian Campbell

dm: i2c: Provide an offset length parameter where needed

2015-01-30T00:09:53Z

Rather than assuming that the chip offset length is 1, allow it to be provided. This allows chips that don't use the default offset length to be used (at present they are only supported by the command line 'i2c' command which sets the offset length explicitly).

dm: i2c: Rename driver model I2C functions to permit compatibility

2015-01-30T00:09:53Z

Add a dm_ prefix to driver model I2C functions so that we can keep the old ones around. This is a little unfortunate, but on reflection it is too difficult to change the API. We can undo this rename when most boards and drivers are converted to use driver model for I2C. Signed-off-by: Simon Glass

sunxi: axp221: Add ELDO[1-3] support

2015-01-22T11:34:56Z

And also add Kconfig option for selecting ELDO3 voltage. The reason for having this option is that the Android kernel sets ELDO3 to 1.2V when powering up LCD in the case if 'lcd_if' configuration variable is set to 6 (LCD_IF_EXT_DSI) in the FEX file. Most likely to supply power for a SSD2828 chip. However on the MSI Primo81 tablet, which is using this particular 'lcd_if = 6' setup for LCD, setting the ELDO3 voltage appears to be unnecessary and it works regardless. Having no schematics of this tablet, I can only guess that 1.2V is supplied to SSD2828 in some other way. Signed-off-by: Siarhei Siamashka Acked-by: Hans de Goede Signed-off-by: Hans de Goede

sunxi: axp209: Disable interrupts when intializing the axp209

2015-01-22T11:34:55Z

We do not use the axp209 interrupt, and at least in my mini-x (which does not have a power button) the pwr-button pin and the irq pin are soldered together, so if the axp209 keeps it irq asserted too long it will see a 10s pwr-button press and hard power off the board, disabling the irqs fixes this.

sunxi: axp221: Add support for controlling the drivebus pin

2015-01-14T13:56:40Z

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 Acked-by: Ian Campbell

sunxi: axp221: Protect axp221_init against multiple calls

2015-01-14T13:56:40Z

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. Signed-off-by: Hans de Goede Acked-by: Ian Campbell

sunxi: axp221: correct ALDO2 description for sun6i

2015-01-14T13:56:40Z

ALDO2 is used to power LPDDR2 SDRAM on both the reference design and the Hummingbird A31, when this type of RAM is present. Signed-off-by: Chen-Yu Tsai Acked-by: Hans de Goede Signed-off-by: Hans de Goede
