2020-05-10imx: imx8qm/imx8qxp: Power down the resources before SPL jump to u-bootPeng Fan1-0/+35
Make sure that all devices that are powered up by SPL are powered down before entering into the u-boot. Otherwise the subsystem/device will never be powered down by SCFW, due to SPL and u-boot are in different partitions. Benefiting from power domain driver, this patch implements the function "imx8_power_off_pd_devices" to power off all active devices. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2020-05-10imx8: Replace SC_R_LAST with SC_R_NONE in DTBLeonard Crestez1-3/+3
We are currently using SC_R_LAST as a marker for imx8 power domain tree nodes without a resource attached. This value is compiled into dtb as part of the linux build and used by uboot. The SC_R_LAST constant changes frequently as SCFW resources are added (by design) and every time we need to update linux and uboot headers together or boot can fail. Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE defined to be 0xFFF0.

When fspi is assigned to M4, we have to let the fspi probe failed when its power domain is failed to power up. Because not all devices have power domain (for example, external devices on the board). Current checking resource owner in power domain probe is not good, change to check it in power on. Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
2020-05-10power: imx8: remove the resource owned check before power offPeng Fan1-4/+4
For all the devices used and set ACTIVE in U-Boot, U-Boot needs to power off all of them without the check of resource owner. When we create software partition before booting Linux, the resource own checkw will return false, and cause the power domain not powered off. If without the check of resource owner, the power domain in the other software partition could be powered off with parent partition could access child partition resources.

This is not expected by imx8-power-domain-legacy driver. Power off parent PD is controlled by the driver internally.

Add power_domain_lookup_name interface to power domain uclass to find a power domain device by its DTB node name, not using its associated client device. Through this interface, we can operate the power domain devices directly. This is needed for non-DM drivers. Modified from Ye's NXP downstream patch only for legacy imx8 power domain driver, since we have not migrated to use new power domain driver.

2020-03-10power-domain: fix hang in endless loop on i.MX8Anatolij Gustschin1-0/+11
Currently when booting the kernel on i.MX8 U-Boot hangs in an endless loop when switching off dma, connectivity or lsio power domains during device removal. It hapens first when removing gpio0 (gpio@5d080000) device, here its power domain device 'lsio_gpio0' is obtained for switching off power. Since the obtained 'lsio_gpio0' device is removed afterwards, its power domain is also switched off and here the parent power domain device 'lsio_power_domain' is optained for switching off the power. Thereafter, when the obtained 'lsio_power_domain' is removed, device_remove() removes its first child 'lsio_gpio0'. During this child removal the 'lsio_power_domain' device is obtained again for switching and when removing it later, the same child removal is repeated, so we are stuck in an endless loop. Below is a snippet from dm tree on i.MX8QXP for better illustration of the DM devices relationship: Class Index Probed Driver Name ----------------------------------------------------------- root 0 [ + ] root_driver root_driver ... simple_bus 0 [ + ] generic_simple_bus |-- imx8qx-pm power_doma 0 [ + ] imx8_power_domain | |-- lsio_power_domain power_doma 1 [ + ] imx8_power_domain | | |-- lsio_gpio0 power_doma 2 [ + ] imx8_power_domain | | |-- lsio_gpio1 Do not remove a power domain device if it is a parent of the currently controlled device.

2020-02-11regulator: fix: Move code to enable gpio regulator to pre_probe from ↵Lukasz Majewski2-5/+3
ofdata_to_platdata 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.

2020-02-06dm: core: Create a new header file for 'compat' featuresSimon Glass18-0/+19
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.
