This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://www.ti.com/lit/pdf/SWCZ010: DCDC o/p voltage can go higher than programmed value Impact: VDDI, VDD2, and VIO output programmed voltage level can go higher than expected or crash, when coming out of PFM to PWM mode or using DVFS. Description: When DCDC CLK SYNC bits are 11/01: * VIO 3-MHz oscillator is the source clock of the digital core and input clock of VDD1 and VDD2 * Turn-on of VDD1 and VDD2 HSD PFETis synchronized or at a constant phase shift * Current pulled though VCC1+VCC2 is Iload(VDD1) + Iload(VDD2) * The 3 HSD PFET will be turned-on at the same time, causing the highest possible switching noise on the application. This noise level depends on the layout, the VBAT level, and the load current. The noise level increases with improper layout. When DCDC CLK SYNC bits are 00: * VIO 3-MHz oscillator is the source clock of digital core * VDD1 and VDD2 are running on their own 3-MHz oscillator * Current pulled though VCC1+VCC2 average of Iload(VDD1) + Iload(VDD2) * The switching noise of the 3 SMPS will be randomly spread over time, causing lower overall switching noise. Workaround: Set DCDCCTRL_REG[1:0]= 00. Signed-off-by: Jan Remmet <j.remmet@phytec.de> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org

* regulator: tps65910: Remove unused min_uV and max_uV from struct tps_infoAxel Lin2012-06-221-50/+0
| | | | | | | | | | | | | | | The min_uV and max_uV fields of struct tps_info are not used in the code. For the case voltage_table is provided, the min_uV and max_uV are the same values as volt_table[0] and volt_table[n_voltages -1]. For the case voltage_table is not available, having the min_uV and max_uV seems misleading. Current code uses equations to get the voltage value in this case, but these equations do not use the min_uV and max_uV fields of struct tps_info. Thus this patch removes the min_uV and max_uV fields from struct tps_info.

| * mfd: Commonize tps65910 regmap access through headerRhyland Klein2012-05-201-46/+42
| | | | | | | | | | | | | | | | | | | | This change removes the read/write callback functions in favor of common regmap accessors inside the header file. This change also makes use of regmap_read/write for single register access which maps better onto what this driver actually needs.
