regulator: fix: Move code to enable gpio regulator to pre_probe from ofdata_to_platdata

2020-02-10T23:00:38Z

The commit e8e9715df2d4 ("regulator: fixed: Modify enable-active-high behavior") fixed the regulator driver behavior when 'enable-active-high' is defined. Unfortunately, this patch used dm_regulator_platdata()'s "boot_on" member to set GPIOD_IS_OUT_ACTIVE flag and enable the regulator. The issue here is that regulator_common_ofdata_to_platdata() is called _before_ regulator_pre_probe() function in which the 'regulator-boot-on' property is asserted. As a result the GPIOD_IS_OUT_ACTIVE flag is not set and gpio_request_by_name() called in the former function is not enabling the regulator. This is problematic for e.g. i.MX ethernet driver, which then tries to perform initialization without power (and fails). The solution here is to explicitly enable regulator in regulator_pre_probe() callback only when 'regulator-boot-on' property is present in device tree. The GPIOD_IS_OUT_ACTIVE flag is not set at all, but relevant gpio is requested. Signed-off-by: Lukasz Majewski Reviewed-by: Patrice Chotard Tested-by: Patrice Chotard

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46Z

At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

dm: core: Require users of devres to include the header

2020-02-06T02:33:46Z

At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres. Signed-off-by: Simon Glass Reviewed-by: Anatolij Gustschin

power: regulator: tps62360_regulator: Convert ofdata_to_platdata to the missing probe

2020-01-20T04:40:28Z

commit 29f7d05a347a ("dm: core: Move ofdata_to_platdata() call earlier") introduces changes in the order of device_probe execution. ofdata_to_platdata now comes before the probe function which resulted in a deadlock and caused boot hang on AM6 devices. Deadlock sequence: tps62360_regulator_ofdata_to_platdata --> i2c_get_chip --> device_probe(tps62360) --> tps62360_regulator_ofdata_to_platdata Hence convert ofdata_to_platdata to the missing probe function to fix the hang.
