2011-07-10tty/serial: Add devicetree support for nVidia Tegra serial portsGrant Likely2-1/+2
Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-07-08dt: add empty of_property_read_u32[_array] for non-dtShawn Guo1-8/+21
The patch adds empty functions of_property_read_u32 and of_property_read_u32_array for non-dt build, so that drivers migrating to dt can save some '#ifdef CONFIG_OF'. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> [grant.likely: Moved things around so only one new static inline is needed] [grant.likely: Added _string variant] Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-07-07dt: bindings: move SEC node under new crypto/Kim Phillips1-1/+1
Since technically it's not powerpc arch-specific. Also rename it sec2 to differentiate it from its incompatible successor, the SEC 4. Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-07-06dt: add helper function to read u32 arraysRob Herring2-8/+25
Rework of_property_read_u32 to read an array of values. Then of_property_read_u32 becomes an inline with array size of 1. Also make struct device_node ptr const. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-07-04tty/serial: change of_serial to use new of_property_read_u32() apiGrant Likely1-22/+15
Simplifies the code a bit and drops a few lines. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Arnd Bergmann <arnd@arndb.de>
2011-07-03dt: add 'const' for of_property_read_string parameter **out_stringShawn Guo2-2/+2
The existing dt codes usually call of_get_property to get a string property and save it as a 'const char *'. The patch adds'const' for of_property_read_string parameter **out_string to make the converting of existing code a little easier.

2011-06-30dt: add helper functions to read u32 and string property valuesThomas Abraham2-0/+62
Add helper functions to retrieve unsigned integer and string property values from properties of a device node. These helper functions can be used to lookup a property in a device node, perform error checking and read the property value. [grant.likely@secretlab.ca: Proposal and initial implementation] Signed-off-by: Thomas Abraham <thomas.abraham@linaro.org> [grant.likely: some word smithing and be more defensive validating the string] Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-06-30tty: of_serial: support for 32 bit accessesJamie Iles2-0/+20
Some platforms e.g. TI Davinci require 32-bit accesses to the UARTs. The of_serial driver currently registers all UARTs as UPIO_MEM. Add a new attribute "reg-io-width" to allow the port to be registered with different IO width requirements.
