Currently this is done by implementing suspend_late() ops in the regulator driver but this is painful for an I2C controlled regulator. Instead, the proposal is to add a device link between the driver and the consumer at regulator core framework level. To avoid storing the link pointer in the regulator core structure, we create device_link_remove() function that use the same argument as device_link_add(). pascal paillet (3): driver core: Add device_link_remove function regulator: core: Link consumer with regulator driver regulator: core: Change suspend_late to suspend drivers/base/core.c | 30 +++++++++++++++++++++++++++ drivers/regulator/core.c | 44 ++++++++++++++++++++++++++-------------- include/linux/device.h | 1 + include/linux/regulator/driver.h | 2 +- 4 files changed, 61 insertions(+), 16 deletions(-) -- 1.9.1
