Matti Vaittinen 2a6a7aacd4 mfd: regulator: clk: Split rohm-bd718x7.h
Split the bd718x7.h to ROHM common and bd718x7 specific parts
so that we do not need to add same things in every new ROHM
PMIC header. Please note that this change requires changes also
in bd718x7 sub-device drivers for regulators and clk.

regulator: bd718x7: Support SNVS low power state
read ROHM BD71837 / BD71847 specific device tree bindings for
controlling the PMIC shutdown/reset states and voltages for
different HW states. The PMIC was designed to be used with NXP
i.MX8 SoC and it supports SNVS low power state which seems to
be typical for NXP i.MX SoCs. However, when SNVS is used we must
not allow SW to control enabling/disabling those regulators which
are crucial for system to boot as there is a HW limitation which
causes SW controlled regulators to be kept shut down after SNVS
reset.

Allow setting the SNVS to be used as reset target state and allow
marking those regulators which are critical for boot.

Merge branch 'for-linus' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator into regulator-4.21 2018-12-11 20:44:49 +00:00
Matti Vaittinen e770b18bbb
regulator: bd718x7: Change next state after poweroff to ready
BD71837 and BD71847 have a HW functionality which leave power
rails OFF after powerof state:
- if they have been controlled by SW.
- if state transition from poweroff is done to SNVS

BD71837 can after reset transition from power-off to SNVS or
READY state depending on reset reason. By default only wathcdog
reset changes state from poweroff to ready. Change PMIC
configuration to always transition to READY in order to avoid
crucial power rails being OFF after reset.

If SNVS is required the crucial power rails should not be
controlled by SW - eg corresponding regulator control register
should have SEL bit kept zero. Currently the driver assumes all
regulators to be controlled by SW so it sets all SEL bits to 1.

Geert Uytterhoeven de226ebda9
regulator: bd718x7: Remove double indirection for bd718xx_pmic_inits.rdatas
With gcc 4.1:

    drivers/regulator/bd718x7-regulator.c: In function ‘bd718xx_probe’:
    drivers/regulator/bd718x7-regulator.c:1020: warning: initialization from incompatible pointer type
    drivers/regulator/bd718x7-regulator.c:1024: warning: initialization from incompatible pointer type

Apparently this old compiler can't handle the obscure double
indirection.

However, there is no need for a double indirection.  Just store a
pointer to the array instead, like other drivers tend to do.
