* fdt: Add basic support for decoding GPIO definitionsSimon Glass2012-03-29-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds some support into fdtdec for reading GPIO definitions from the fdt. We permit up to FDT_GPIO_MAX GPIOs in the system. Each GPIO is of the form: gpio-function-name = <phandle gpio_num flags>; where: phandle is a pointer to the GPIO node gpio_num is the number of the GPIO (0 to 223) flags is a flag, as follows: bit meaning 0 0=polarity normal, 1=active low (inverted) An example is: enable-propounder-gpios = <&gpio 43 0>; which means that GPIO 43 is used to enable the propounder (setting the GPIO high), or that you can detect that the propounder is enabled by checking if the GPIO is high (the fdt does not indicate input/output). Two main functions are provided: fdtdec_decode_gpio() reads a GPIO property from an fdt node and decodes it into a structure. fdtdec_setup_gpio() sets up the GPIO by calling gpio_request for you. Both functions can cope with the property being missing, which is taken to mean that that GPIO function is not available or is not needed. [For reference, from Stephen Warren <swarren@nvidia.com>. It may be that we add this extra complexity later if needed: The correct way to parse such a GPIO property in general is: * Read the first cell. * Find the node referenced by the phandle (the controller). * Ensure property gpio-controller is present in the controller node. * Read property #gpio-cells from the controller node. * Extract #gpio-cells from the original property. * Keep processing more cells from the original property; there may be multiple GPIOs listed. According to the binding documentation in the Linux kernel, Samsung Exynos4 doesn't use this format, and while all other chips do have a flags cell, about 50% of the controllers indicate the cell is unused. ] Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
* fdt: Add functions to access phandles, arrays and boolsSimon Glass2012-03-29-0/+39
| | | | | | | | | | | | Add a function to look up a property which is a phandle in a node, and another to read a fixed-length integer array from an fdt property. Also add a function to read boolean properties, although there is no actual boolean type in U-Boot.

* fdt: Tidy up a few fdtdec problemsSimon Glass2012-03-29-4/+19
| | | | | | | | | | | | | | | | This fixes five trivial issues in fdtdec.c: 1. fdtdec_get_is_enabled() doesn't really need a default value 2. The fdt must be word-aligned, since otherwise it will fail on ARM 3. The compat_names[] array is missing its first element. This is needed only because the first fdt_compat_id is defined to be invalid. 4. Added a header prototype for fdtdec_next_compatible() 5. Change fdtdec_next_alias() to only increment its 'upto' parameter on success, to make the display error messages in the caller easier.

* fdt: Add fdtdec_find_aliases() to deal with alias nodesSimon Glass2012-03-29-0/+47
| | | | | | | | | | | | | | | | Stephen Warren pointed out that we should use nodes whether or not they have an alias in the /aliases section. The aliases section specifies the order so far as it can, but is not essential. Operating without alisses is useful when the enumerated order of nodes does not matter (admittedly rare in U-Boot). This is considerably more complex, and it is important to keep this complexity out of driver code. This patch creates a function fdtdec_find_aliases() which returns an ordered list of node offsets for a particular compatible ID, taking account of alias nodes.

* bootstage: Implement core microsecond boot time measurementSimon Glass2012-03-18-0/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This defines the basics of a new boot time measurement feature. This allows logging of very accurate time measurements as the boot proceeds, by using an available microsecond counter. To enable the feature, define CONFIG_BOOTSTAGE in your board config file. Also available is CONFIG_BOOTSTAGE_REPORT which will cause a report to be printed just before handing off to the OS. Most IDs are not named at this stage. For that I would first like to renumber them all. Timer summary in microseconds: Mark Elapsed Stage 0 0 reset 205,000 205,000 board_init_f 6,053,000 5,848,000 bootm_start 6,053,000 0 id=1 6,058,000 5,000 id=101 6,058,000 0 id=100 6,061,000 3,000 id=103 6,064,000 3,000 id=104 6,093,000 29,000 id=107 6,093,000 0 id=106 6,093,000 0 id=105 6,093,000 0 id=108 7,089,000 996,000 id=7 7,089,000 0 id=15 7,089,000 0 id=8 7,097,000 8,000 start_kernel Signed-off-by: Simon Glass <sjg@chromium.org>
