2014-09-26mfd: tps65910: Work around silicon erratum SWCZ010Arnout Vandecappelle (Essensium/Mind)1-0/+5
http://www.ti.com/lit/pdf/SWCZ010: Glitch on SDA-SCL not managed correctly by the I2C IP Impact: The standard specifies that the I2C transfer should restart on a start event in all cases. The current design does not support two consecutive Start conditions. This can cause the first real access after such a glitch to be corrupted. Description: An unexpected glitch on SDA and SCL can generate a wrong start event. In the current design, the SCL line must toggle two times to detect a new start event and completely restart the I2C access; hence the real start event is not detected in the case of a single SCL toggle. Workaround: Repeat I2C access. A simpler workaround is to make a dummy transfer just before the first access to the tps65910 chip. This can be done unconditionally.

2014-09-26mfd: arizona: Avoid use of legacy IRQ mappingCharles Keepax1-2/+2
regmap_add_irq_chip is called from arizona_irq_init with the irq_base specified as -1 and regmap_add_irq_chip uses if (irq_base) to check if it should use legacy IRQ mapping. As such the irq mappings are currently added with irq_domain_add_legacy, rather than irq_domain_add_linear. This is clearly a typo as there is no reason why this driver can't use irq_domain_add_linear. This patch corrects this by passing the irq_base as zero to regmap_add_irq_chip.

Mark some additional registers as volatile. The write sequencer control registers should not be cached, as we don't ever want their value synchronised as this might cause a write sequence to be accidentally initiated. Additionally, the DAC_COMP registers require special preconditions to write so there values wouldn't be updated accurately during a register sync.

2014-09-26mfd: menelaus: Remove null pointer dereferenceHimangi Saraogi1-3/+0
If vtg is NULL, it is not possible to access its mode_reg field. At all sites where the static function menelaus_set_voltage is called, the first argument is the address of a structure defined in the file. So, the null test is unnecessary and is removed. Also, a label is done away with.
