2013-05-10palmas: use palmas_i2c_[read|write]_u8Nishanth Menon
commit 21144298 (power: twl6035: add palmas PMIC support) introduced twl6035_i2c_[read|write]_u8 Then, commit dd23e59d (omap5: pbias ldo9 turn on) introduced palmas_[read|write]_u8 for precisely the same access function. TWL6035 belongs to the palmas family, so instead of having an twl6035 API, we could use an generic palmas API instead. To stay consistent with the function naming of twl4030,6030 accessors, we use palmas_i2c_[read|write]_u8 Cc: Balaji T K <balajitk@ti.com> Cc: Sricharan R <r.sricharan@ti.com> Reported-by: Ruchika Kharwar <ruchika@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com>

2012-03-27twl4030: fix potential power supply handling issuesGrazvydas Ignotas
twl4030_pmrecv_vsel_cfg currently first sets up device group (effectively enabling the supply), and only then sets vsel (selects voltage). This could lead to wrong voltage for a short time, or even long time if second i2c write fails. Fix this by writing vsel first and device group after that. Also introduce error checking to not enable the supply if we failed to set the voltage, and start logging errors as power supply problems are usually important.

MMC interfaces are specified to be 3.3V compatible with an operating voltage range of 3.1V to 3.5V for SD cards. This change affects hardware using TWL4030 (TPS6595x) PMICs and should improve the reliability when communicating with marginally-spec'd MMC devices. 3.15V is the highest possible level for this chip.

2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
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>
