dm: core: Add functions to get strings and the string count from a stringlist

2017-09-22T14:23:54Z

dev_read_string_count() is used to get the number of strings in a stringlist. dev_read_string_index() is used to get a string in the stringlist based on its position in the list. Signed-off-by: Jean-Jacques Hiblot

dm: core: add dev_read_addr_ptr()

2017-09-18T18:40:33Z

The dev_read_addr_ptr() mimics the behaviour of the devfdt_get_addr_ptr(), retrieving the first address of the node's reg-property and returning it as a pointer (or NULL on failure). Signed-off-by: Philipp Tomsich Acked-by: Philipp Tomsich Reviewed-by: Simon Glass

dtoc: Add support for 32 or 64-bit addresses

2017-09-15T11:27:38Z

When using 32-bit addresses dtoc works correctly. For 64-bit addresses it does not since it ignores the #address-cells and #size-cells properties. Update the tool to use fdt64_t as the element type for reg properties when either the address or size is larger than one cell. Use the correct value so that C code can obtain the information from the device tree easily. Alos create a new type, fdt_val_t, which is defined to either fdt32_t or fdt64_t depending on the word size of the machine. This type corresponds to fdt_addr_t and fdt_size_t. Unfortunately we cannot just use those types since they are defined to phys_addr_t and phys_size_t which use 'unsigned long' in the 32-bit case, rather than 'unsigned int'. Add tests for the four combinations of address and size values (32/32, 64/64, 32/64, 64/32). Also update existing uses for rk3399 and rk3368 which now need to use the new fdt_val_t type.

dm: core: add clocks node scan

2017-09-12T03:43:58Z

Currently, all fixed-clock declared in "clocks" node in device tree can be binded by clk_fixed_rate.c driver only if each of them have the "simple-bus" compatible string. This constraint has been invoked here [1]. This patch offers a solution to avoid adding "simple-bus" compatible string to nodes that are not busses.

dm: core: Add ofnode_for_each_subnode()

2017-09-12T03:43:58Z

Add a convenience macro to iterate over subnodes of a node. Make use of this where appropriate in the code. Signed-off-by: Simon Glass

dm: core: Show driver name with 'dm tree'

2017-09-12T03:43:58Z

It is often useful to see which driver was actually selected for each device. Add a new 'Driver' column to provide this information. Sample output: Class Probed Driver Name ---------------------------------------- root [ + ] root_drive root_driver keyboard [ + ] i8042_kbd |-- keyboard serial [ + ] ns16550_se |-- serial rtc [ ] rtc_mc1468 |-- rtc timer [ + ] tsc_timer |-- tsc-timer syscon [ + ] ich6_pinct |-- pch_pinctrl pci [ + ] pci_x86 |-- pci northbridge [ + ] bd82x6x_no | |-- northbridge@0,0 video [ + ] bd82x6x_vi | |-- gma@2,0 vidconsole0 [ + ] vidconsole | | `-- gma@2,0.vidconsole0 ...

dm: core: Drop use of strlcpy()

2017-09-12T03:43:58Z

We can use printf() to limit the string width. Adjust the code to do this instead of using strlcpy() which is a bit clumbsy. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Tested-by: Bin Meng

ofnode: add {ofnode, dev}_read_resource_byname()

2017-08-29T14:56:17Z

Linux supports platform_get_resource_byname() to look up a resource by name. We want a similar helper. It is useful when a device node has named register regions. Signed-off-by: Masahiro Yamada Reviewed-by: Simon Glass

dm: core: Avoid calling dm_scan_fdt_dev() with of-platdata

2017-08-17T07:44:16Z

We cannot call dm_scan_fdt_dev() with of-platdata since there is no device tree. Fix this with an #if check. Fixes: 3be9a37 (dm: syscon: scan sub-nodes of the syscon node) Signed-off-by: Simon Glass

spl: dm: Kconfig: split REGMAP/SYSCON support for TPL from SPL

2017-08-13T15:12:20Z

This change introduces TPL variants of the REGMAP and SYSCON config options (i.e. TPL_REGMAP and TPL_SYSCON in analogy to SPL_REGMAP and SPL_SYSCON) in preparation of a finer-grained feature selection for building feature-rich TPL variants.
