* i2c: Add support for designware i2c controllerVipin KUMAR2012-04-24-1/+1
| | | | | | | | | | | | | Earlier, a driver exists in the u-boot source for designware i2c interface. That driver was specific to spear platforms. This patch implements the i2c controller as a generic driver which can be used by multiple platforms The driver files are now renamed to designware_i2c.c and designware_i2c.h and these are moved into drivers/i2c folder for reusability by other platforms Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Amit Virdi <amit.virdi@st.com>
* sh: i2c: Add support I2C controller of SH7734Nobuhiro Iwamatsu2012-04-24-0/+1
| | | | | | | | | | | | | | | | | | | | | | Renesas SH7734 has two I2C interfaceis. This supports these I2C. V5: - include i2c.h. - Add check of icsr bit polling logic. - Implement i2c_probe. V4: - Remove sh_i2c_dump_reg function. - Use puts() when there's no format. - Chnage check for I2C bus number. - Remove space before the semi-colon. V3: - Fix error for whitespace. V2: - Changed bit control to use the clr|set|clrsetbits_* functions. - Fix wrong comment style. - Add new line before for loop in i2c_read.

| | | | | | | | | | | | | Add basic i2c driver for Tegra2 with 8- and 16-bit address support. The driver requires CONFIG_OF_CONTROL to obtain its configuration from the device tree.

* pxa: move i2c driver to the common placeLei Wen2011-04-27-0/+1

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

* | Blackfin: overhaul i2c driverMike Frysinger2009-01-28-0/+1
|/ | | | | | | | | | | The current Blackfin i2c driver does not work properly with certain devices due to it breaking up transfers incorrectly. This is a rewrite of the driver and relocates it to the newer place in the source tree. Also remove duplicated I2C speed defines in Blackfin board configs and disable I2C slave address usage since it isn't implemented. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
