2024-09-07regulator: Add AXP717 boost supportMark Brown1-0/+4
Merge series from Andre Przywara <andre.przywara@arm.com>: This is remainder of the AXP717 fix series, containing support for the boost regulator. This is meant to increase the battery voltage to the 5 volts required to provide the USB VBUS power. It's the usual trinity of DT bindings patch (1/3), the MFD part describing the PMIC registers (2/3) and the final patch to model the regulator (3/3). Compared to v2, this drops the merged patches, and just retains the boost related parts. It also changes the internal name of the register to AXP717_MODULE_EN_CONTROL_2, since there is another control register we will need later for battery support.

2024-08-06regulator: bd9576: Constify struct linear_rangeChristophe JAILLET1-4/+4
'struct linear_range' are not modified in these drivers. Constifying this structure moves some data to a read-only section, so increase overall security. This is also more consistent with the other struct linear_range declaration above. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 20767 4544 0 25311 62df drivers/regulator/bd9576-regulator.o After: ===== text data bss dec hex filename 21023 4288 0 25311 62df drivers/regulator/bd9576-regulator.o Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://patch.msgid.link/a4e37991ea7b47145ab033128c8dd49f73a983e6.1722949232.git.christophe.jaillet@wanadoo.fr Signed-off-by: Mark Brown <broonie@kernel.org>
2024-08-01regulator: Use of_property_read_bool()Rob Herring (Arm)2-6/+3
Use of_property_read_bool() to read boolean properties rather than of_get_property(). This is part of a larger effort to remove callers of of_get_property() and similar functions. of_get_property() leaks the DT property data pointer which is a problem for dynamically allocated nodes which may be freed.

Since the regulator can't be used without the USB controller also tighten the dependency to match, as well as the default.
