2016-01-21gpio: Allow 's' as an abbreviation for 'status'Simon Glass
The 'gpio' command allows abbreviations for most subcommands. Allow them for 'status' also. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: jerry: Drop unused optionsSimon Glass
To reduce the SPL image size, drop the LED features. Jerry does not have an LED and we can leave out GPIO support also. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: Disable simple-bus in SPL for firefly-rk3288, jerrySimon Glass
This is not needed for booting, so drop it from SPL to save about 300 bytes. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: jerry: Enable the RK808 PMIC and regulatorSimon Glass
Enable this PMIC and regulator, which is used on jerry. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: Move firefly and jerry to use the full pinctrlSimon Glass
Use the full pinctrl driver in U-Boot proper. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: pinctrl: Add a full pinctrl driverSimon Glass
We can make use of the device tree to configure pinctrl settings. Add this support for the driver so we can use it in U-Boot proper. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: mmc: Update the driver to use the new clock IDSimon Glass
We can use the new clk_get_by_index() function to get the correct clock. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: spi: Avoid setting the pinctrl twiceSimon Glass
If full pinctrl is enabled we don't need to manually set the pinctrl in the driver. It will happen automatically. Adjust the code to suit - we will still use manual mode in SPL. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: spi: Update the driver to use the new clock IDSimon Glass
We can use the new clk_get_by_index() function to get the correct clock. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: i2c: Update the driver to use the new clock IDSimon Glass
We can use the new clk_get_by_index() function to get the correct clock. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: clock: Add a function to find a clock by IDSimon Glass
The current approach of using uclass_get_device() is error-prone. Another clock (for example a fixed-clock) may cause it to break. Add a function that does a proper search. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: clk: Add a function to get a peripheral clock rateSimon Glass
It is useful to be able to read the rate of a peripheral clock. Add a handler for that. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: clock: Rename the general clock variable to gclk_rateSimon Glass
The current name is confusing and a bit verbose. Rename it. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: Use a separate clock ID for clocksSimon Glass
At present we use the same peripheral ID for clocks and pinctrl. While this works it is probably better to use the device tree clock binding ID for clocks. We can use the clk_get_by_index() function to find this. Update the clock drivers and the code that uses them. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: jerry: Disable pmic-int-1 setup to avoid a hangSimon Glass
This hangs when activated (by probing the PMIC). Disable it for now until we understand the root cause. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: Use pwrseq for MMC start-up on jerrySimon Glass
This is defined in the device tree in Linux. Copy over the settings so that this can be used instead of hard-coding the reset line. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: Correct the defconfig orderSimon Glass
This has got out of sequence somehow. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: mmc: Use a pwrseq device if availableSimon Glass
Use the pwrseq uclass to find a suitable power sequence for the MMC device. If this is enabled in the device tree, we will pick it up automatically. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: Convert the PMU IOMUX registers into an arraySimon Glass
This is easier to deal with when using generic code since it allows us to use a register index instead of naming each register. Adjust it, adding an enum to improve readability. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: Avoid using MMC code when not booting from MMCSimon Glass
This saves some code space in SPL which is useful on jerry. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21dm: Add a power sequencing uclassSimon Glass
Some devices need special sequences to be used when starting up. Add a uclass for this. Drivers can be added to provide specific features as needed. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21power: Add support for RK808 regulatorsSimon Glass
Add regulator support for the RK808 PMIC. It integrated 4 BUCKs and 8 LDOs all of which are supported by this driver. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21power: Add base support for the RK808 PMICSimon Glass
This Rockchip PMIC provides features suitable for battery-powered applications. It is commonly used with Rockchip SoCs. Add a driver which provides register access. The regulator driver will use this. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21dts: Bring in pinctrl device tree bindingSimon Glass
Add this binding file since we now use it in U-Boot. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21dm: pmic: Add 'reg status' to show all regulatorsSimon Glass
It is convenient to be able to see the status of all regulators in a list. Add this feature to the 'reg status' command. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21dm: pinctrl: Add a function to parse PIN_CONFIG flagsSimon Glass
Add a function which produces a flags word from a few common PIN_CONFIG settings. This is useful for simple pinctrl drivers that don't need to worry about drive strength, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21dm: core: Don't set pinctrl for pinctrl devicesSimon Glass
There is sort-of race condition when a pinctrl device is probed. The pinctrl function is called which may end up using the same device as is being probed. This results in operations being used before the device is actually probed. For now, disallow pinctrl operations on pinctrl devices while probing. An alternative solution would be to move the operation to later in the device_probe() function (for pinctrl devices only) but this needs more thought. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: kylin: Store env in emmcJeffy Chen
There's a 64K reserved area at the end of the first 4M. Store env there, so we can use fastboot to flash it. Signed-off-by: Jeffy Chen <jeffy.chen@rock-chips.com> Acked-by: Simon Glass <sjg@chromium.org>
2016-01-21rockchip: kylin: Check fastboot requestJeffy Chen

2016-01-21dm: clk: Add support for decoding clocks from the device treeSimon Glass
Add a method which can locate a clock for a device, given its index. This uses the normal device tree bindings to return the clock device and the first argument which is normally used as a peripheral ID in U-Boot.

2016-01-21clk: add fixed rate clock driverMasahiro Yamada
This commit intends to implement "fixed-clock" as in Linux. (drivers/clk/clk-fixed-rate.c in Linux) If you need a very simple clock to just provide fixed clock rate like a crystal oscillator, you do not have to write a new driver. This driver can support it.

2016-01-20dm: stdio: video: Plumb the video uclass into stdioSimon Glass
Register video drivers with stdio so that they can be used for text output. This needs to be done explicitly for now. At some point we should be able to convert stdio itself to driver model and avoid this step. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2016-01-20dm: video: Implement the bmp command for driver modelSimon Glass
This command can use the bitmap display code in the uclass. This is similar to the code in lcd.c and cfb_console.c. These other copies will go away when all boards are converted to use driver model for video. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2016-01-20dm: common: Add memory reservation for the video uclassSimon Glass
Before relocation we need to reserve memory for the video driver frame buffers so that they can use this memory when they start up (after relocation). Add a call to the uclass to permit this. The current top and bottom of the region is stored in global_data so that it can be checked post-relocation to ensure enough memory is available. No video device should be probed before relocation.

2016-01-20dm: video: Add a driver for a rotated text consoleSimon Glass
Sometimes the console must be rotated. Add a driver which supports rotating the text clockwise to 90, 180 and 270 degrees. This can support devices where the display is rotated for mechanical reasons. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
