regulator: qcom_spmi: Update mvs1/mvs2 switches on pm8941

2016-10-07T13:23:43+00:00

commit 93bfe79b03365f410aa91caf04263173c008ecdf upstream.

The mvs1 and mvs2 switches are actually called 5vs1 and 5vs2 on
some datasheets. Let's rename them to match the datasheets and
also match the RPM based regulator driver which calls these by
their 5vs names (see qcom_smd-regulator.c). There aren't any
users of these regulators so far, so there aren't any concerns of
DT ABI breakage here. While we're here making updates to the
switches, also mandate usage of the OCP irq for these switches
too.

regulator: qcom_spmi: Add support for get_mode/set_mode on switches

2016-10-07T13:23:43+00:00

commit 919163f6362ac23138d31fc8befdd52e5d7e488d upstream.

The voltage switches support mode switching, so add support for
these ops to those types of regulators.

regulator: qcom_spmi: Add support for S4 supply on pm8941

2016-10-07T13:23:43+00:00

commit c333dfe8dba7d3e47e97e1cee3c38123e19ae73c upstream.

The S4 supply is sometimes called the boost regulator because it
outputs 5V. Typically it's connected to the 5vs1 and 5vs2
switches for use in USB OTG and HDMI applications. Add support
for this regulator which was mistakenly left out from the initial
submission of this driver.

regulator: qcom_spmi: Fix calculating number of voltages

2015-06-19T15:28:17+00:00

n /= range->step_uV + 1; is equivalent to n /= (range->step_uV + 1);
which is wrong. Fix it.

These lines where missing braces causing the break to always
be executed even when it shouldn't be. Fix it.

regulator: Add QCOM SPMI regulator driver

2015-06-16T11:14:54+00:00

Add an SPMI regulator driver for Qualcomm's PM8841, PM8941, and
PM8916 PMICs. This driver is based largely on code from
codeaurora.org[1].
