regulator: fix: enable gpio when requested

2020-06-15T20:37:01+00:00

The fix in commit b7adcdd073c0 has the side-effect that the regulator
will be disabled when requesting the relevant gpio in
regulator_common_ofdata_to_platdata() and enabled in
regulator_pre_probe() when the regulator was already enabled.
This leads to a short interruption in the 3.3V power to the PCIe
slot on the firefly-rk3399 which makes an ADATA SX8000NP NVMe SSD
unhappy.

Fix this by setting the GPIOD_IS_OUT_ACTIVE flag again when the
'regulator-boot-on' property is set, but check for this property
explicitly instead of relying on the "boot_on" member of
the uclass platdata.

command: Remove the cmd_tbl_t typedef

2020-05-18T22:36:55+00:00

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

imx: imx8qm/imx8qxp: Power down the resources before SPL jump to u-boot

2020-05-10T18:55:20+00:00

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.

imx8: Replace SC_R_LAST with SC_R_NONE in DTB

2020-05-10T18:55:20+00:00

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.

power: imx8: Check owned resource in power on

2020-05-10T18:55:20+00:00

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.

power: imx8: remove the resource owned check before power off

2020-05-10T18:55:20+00:00

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.
